GAO Xin-hua, LIU Zhao-yu
DOI: 10.12117/jccmi.2020.08.002
Objective: To evaluate the efficacy of endovascular aortal repair(EVAR) and remodeling of aortic wall in patients with Stanford type B thoracic aortic dissection(AD). Methods: A total of 30 patients with Stanford type B AD who underwent EVAR were collected. A unified follow-up plan was made for all patients. CTA of the aorta was reviewed regularly at 1 month, 3 months, 6 months and 1 year after the operation to evaluate the changes of the aorta and postoperative complications. Results: In this study, 30 patients were successfully completed EVAR(100%), 21 males(70%), 9 females(30%), aged 36~68 years, the average age was (51.48±3.55) years, including AD 15 cases in acute phase(50%), 9 cases(30%) in subacute phase, 6 cases(20%) in chronic phase. The average follow-up time after EVAR was (17.31±4.28) months. One case died of aortic rupture within one year after operation, and two cases had internal leakage(1 case in type Ⅰ and 1 case in type Ⅱ). After the operation of AD, the aortic stent segment had the best absorption effect, followed by the distal thoracic aorta segment, and the abdominal aorta segment had the worst effect. Compared with AD patients in the acute and subacute phase, the absorption effect of AD patients in chronic phase was significantly decreased(P<0.05). In patients with AD at different stages after surgery, the true lumen diameter of the aorta was larger and the false lumen was smaller than that before surgery, and the difference was statistically significant(P<0.05). Compared with AD in the acute phase and subacute phase, the difference between the true lumen diameter and the false lumen diameter in the chronic phase was smaller. The maximum diameter of the vasculature after EVAR in the acute and subacute phase was smaller than that before EVAR, the difference was statistically significant(before operation in acute phase (3.32±0.19) cm, after operation (2.96±0.27) cm, P=0.00, P<0.05; before operation in subacute phase (3.03±0.28) cm, after operation (2.88±0.37) cm, P=0.04, P<0.05), but the change of the aortic lumen diameter in the chronic phase was not statistically significant(before operation in chronic phase (4.15±0.53) cm, after operation (4.12±0.55) cm, P=0.95, P>0.05). Conclusion: EVAR in the treatment of Stanford type B AD patients has a certain short-term and medium-term effect, promoting the remodeling of the aortic wall after AD surgery, but the effect of EVAR treatment in AD patients with different phases of aortic wall remodeling is different, the effect of aortic remodeling in chronic phase is the worst.

DOI: 10.12117/jccmi.2020.08.005
Objective: To explore the characteristics and treatment of varicose veins of the lower extremities caused by other superficial or great saphenous venous regurgitation combined with other venous regurgitation, except for the valve insufficiency of the great saphenous vein. Materials and Methods: From May 2018 to May 2019, 61 cases(63 limbs) of primary varicose veins of lower extremities caused by non simple saphenous vein valve dysfunction were treated by ultrasound-guided endovenous radiofrequency obliteration combined with varicose vein local exfoliation and sclerotherapy. There were 42 males and 19 females, aged 23~78 years, the average age was (55.9±13.2) years. The types, diameters and CEAP grades of reflux veins were analyzed. The great saphenous vein, small saphenous vein, anterior accessory saphenous vein and pathological perforator vein were all treated with radiofrequency. The superficial varicose veins were treated with foam sclerotherapy. Exfoliation of local varicose vein was performed. After the operation, the patients wore the medical sequential decompression elastic socks. Results: In this group, there were 10 types of varicose veins in the lower extremities caused by the non simple valve insufficiency of the great saphenous vein. The proportion of severe varicose veins(C4~C6) was 34/63, 54.0% in the limbs with non simple great saphenous valve insufficiency. The highest incidence of severe varicose veins was 81.8%(27/33). The success rate of operation was 100%. Forty-four cases were followed up in 61 patients, with a follow-up rate of 72.1%. There were 15 limbs with varicose veins disappearance and 24 limbs with clinical grade degradation in 44 limbs. The effective rate was 88.6%. Conclusion: It is necessary to master the hemodynamics of the superficial veins of the lower extremities in the preoperative diagnosis of the patients with primary varicose veins of the lower extremities. Endovenous radiofrequency obliteration combined with sclerotherapy is a minimally invasive, safe and effective method for the treatment of primary varicose veins of the lower extremities caused by non simple great saphenous vein dysfunction.

DOI: 10.12117/jccmi.2020.08.006
Objective: To evaluate the clinical application values of CT electromagnetic navigation system-guided 125I seed implantation therapy for parahilar non-small cell lung carcinoma(NSCLC). Methods: A total of 26 patients with parahilar NSCLC treated by CT-guided 125I seed implantation therapy were retrospectively analyzed. The 125I seed implantation procedures were performed under CT electromagnetic navigation and routine CT guidance in 16 and 10 cases, respectively. The preoperative planning designs, intraoperative optimization and postoperative dosimetry verifications were performed for all patients. The dose related parameters including D90, MPD, V100, V150 and V200 were compared between pre- and post-operation by t test. The operating time, adjustment times of puncture needle, total radiation dose during the puncture and complications were also compared between the two groups. Results: All 26 patients were treated successfully without serious procedure-related complications. An average of 33 seeds were implanted in the CT electromagnetic navigation system-guided group, and 40 seeds were implanted in the routine CT guided group. Preoperative V100 in CT electromagnetic navigation system-guided group and routine CT guided group were (95.45±1.52)% and (93.47±2.37)%, respectively. Postoperative V100 in both groups were (89.83±2.78)% and (87.85±4.35)%, respectively. There was no significant difference between pre- and post-operation for all parametersexcept for V100. The operating time was (53.3±11.4) min in CT electromagnetic navigation system-guided group and (66.0±12.7) min in routine CT guided group. The adjustment times of puncture needle were (0.5±0.13) and (2.08±0.11) in both group, respectively. Total radiation dose during the puncture was (206.4±11.19) mGycm and (299.9±8.402) mGycm in both group, respectively. Compared with routine CT guided group, the mean value of the operating time, adjustment times of puncture needle and total radiation dose during the puncture decreased in CT electromagnetic navigation system-guided group. The differences between two groups were statistically significant(P<0.01). Conclusions: Compared with the routine CT guidance, CT electromagnetic navigation system-guided 125I seed implantation therapy for NSCLC can achieve preoperative plans accurately, and effectively reduce the adjustment times of puncture needle, shorten the operation time, reduce radiation dose and improve the patients’ tolerance.

LIANG Xiao-qiu, CAO Ling-ling, CHEN Yi-xu, WANG Yan, DU Hao
DOI: 10.12117/jccmi.2020.08.007
Objective: To assess the efficacy and safety of ultrasound-guided thrombin injection(UGTI) in the treatment of femoral artery pseudoaneurysm(PSA). Method: From November 2017 to December 2019, 24 PSA patients confirmed by angiography or color Doppler ultrasound in our hospital were analyzed, including 19 cases of simple type and 5 cases of complex type. Under the guidance of color Doppler ultrasound, 20G PTC needle was used to puncture into the PSA cavity from the bottom of the PSA cavity far away from the PSA neck, and thrombin solution was injected slowly (concentration 250 IU/mL, total dose ≤1 000 IU). The near PSA cavity was injected preferentially for complex PSA. After operation, thrombin dosage and adverse reactions of each patient were recorded. Ultrasound(US) reexaminations were performed 24 hours and 1 week after operation, to observe the blood flow in PSA cavity and parent artery. Result: Blood flow signal in all 24 cases disappeared, only 2 patients(1 simple type, 1 complex type) had a little residual blood flow in the neck of the PSA. After 24 hours of compression, the blood flow in the neck of the simple PSA disappeared, and the complex PSA was treated successfully for the second time. The success rate of the first treatment was 95.8%(23/24), and the total success rate was 100.0%(24/24). The average thrombin dosage was (180±107) IU(25~500 IU). One patient had transient vasovagal syncope during the operation. One patient developed shivering, fever(39 ℃) 40 minutes after operation, with extensive skin rash, lower limb plaque and hypotension. After intravenous fluid infusion and intravenous injection of 5 mg dexamethasone, the patient was gradually and completely relieved. No adverse reactions and no recurrence were found in the other patients. Conclusion: Ultrasound-guided percutaneous low-dose thrombin injection is a safe and effective therapy method for treating PSA.

DOI: 10.12117/jccmi.2020.08.008
Objective: To investigate the correlation between the signal intensity in globus pallidus(SIgp), the ratio of T1WI signal intensity in globus pallidus to putamen(G/P) and the grades of neonatal hyperbilirubinemia(NHB) and the value in diagnosing NHB brain injury. Methods: The clinical and MRI data of 224 cases of NHB hospitalized from January 2017 to November 2019 were collected, and divided into 6 groups according to the peak level of serum total bilirubin, ranging from B0 to B5. The SIgp and SIp were measured respectively, and the G/P ratio was calculated. The differences between SIgp and G/P in different groups were analyzed by One-way ANOVA. The correlation between SIgp, G/P and serum bilirubin level were analyzed by Spearman. The efficacy of SIgp and G/P in the diagnosis of bilirubin brain injury were analyzed by ROC. Results: There were significant differences in SIgp and G/P between different NHB grades(P<0.05). The differences of SIgp between B0 and B2, B3, B4, B5 groups, B1 and B4, B5 groups were statistically significant respectively(P<0.05). The differences of G/P between B0 and B2, B3, B4, B5 groups, B1 and B2, B3, B4, B5 groups, B2 and B3, B4, B5 groups, B3 and B5 groups, B4 and B5 groups were statistically significant respectively(P<0.01). There was a weak positive correlation between SIgp and NHB grades(rs=0.281, P<0.001), and a strong positive correlation between G/P and NHB grades(rs=0.714, P<0.001). The AUC of G/P in each group was significantly higher than that of SIgp, and the difference of ROC in each group was statistically significant(Z>1.96, P<0.05). Conclusion: G/P ratio can provide objective imaging evidence for the grades of NHB brain injury, and it’s diagnostic efficiency is better than SIgp. It is necessary to be alert to the occurrence of acute bilirubin encephalopathy(ABE) when the G/P ratio is ≥1.160.

DOI: 10.12117/jccmi.2020.08.009
Objective: To investigate the diagnostic value of diffusion kurtosis imaging(DKI) in head and neck lymphoma. Methods: The clinical data of 114 cases of head and neck lymphoma(neck lymphoma group), 97 tumor patients with neck lymph node metastasis(lymph node metastasis group) and 82 healthy individuals with benign lymph nodes(benign lymph node group) diagnosed by biopsy from January 2016 to January 2019 in our hospital were retrospectively analyzed. All the selected subjects underwent the DKI examinations. Diffusion(D) and kurtosis(K) values were recorded, and were compared among head and neck lymphoma patients with different pathological types and cell sources. ROC curve was used to analyze the value of DKI in the diagnosis of head and neck lymphoma. Results: There was significant difference in D value among the three groups(F=96.380, P<0.05). D value of head and neck lymphoma group was significantly lower than that of lymph node metastasis group and benign lymph node group(P<0.05). D value of Non-Hodgkin’s lymphoma(NHL) type was significantly lower than that of Hodgkin’s lymphoma(HL) type(P<0.05). D and K values of NHL from B cells and T cells had no significant difference(P>0.05). When the D value was 1.06×10-3 mm2/s, the AUC, sensitivity and specificity of D value in the diagnosis of head and neck lymphoma was 0.801, 85.09% and 69.83%, respectively. When the D value was 0.94×10-3 mm2/s, the AUC, sensitivity and specificity of D value in the diagnosis of head and neck lymphoma was 0.817, 68.18% and 89.13%, respectively. Conclusion: The D value of magnetic resonance DKI has a high value in the diagnosis and classification of head and neck lymphoma, which can provide a reliable basis for early diagnosis of head and neck lymphoma.

Objective: To evaluate the value of MRI texture analysis in predicting cervical lymph node metastasis of papillary thyroid carcinoma(PTC). Materials and Methods: The imaging and clinical data of 54 patients with PTC diagnosed by operation and pathology were retrospectively analyzed, according to the result of surgical pathology, the patients were divided into lymph node metastasis group(34 cases) and no lymph node metastasis group(20 cases). Preoperative thyroid MRI examination was performed on all patients, ROI was manually delineated on the T2WI axial image of the largest section of the tumor, texture parameters(entropy, standard deviation, contrast, skewness, kurtosis, deficit moment, angular second moment, mean, correlation) were extracted by texture analysis software. The independent sample t-test(normal distribution with homogeneity of variance) and Mann-Whitney U test(non-normal distribution without homogeneity of variance) were used to compare the differences of measurement data between the two groups. The difference of enumeration data was compared by χ2 test. The ROC curve was used to evaluate the texture parameters with statistical significance and to predict the efficacy of cervical lymph node metastasis. P<0.05 was considered statistically significant. Results: The T2WI image entropy(t=-5.64), correlation(Z=-2.67), angular second-order moment(Z=-3.53) and standard deviation(Z=-2.67) between PTC cervical lymph node metastasis group and non-metastasis group were statistically significant(P<0.05). The maximum of the area under ROC curve(AUC) of entropy was 0.884, threshold was 5.59, sensitivity was 97.1%, and specificity was 70%. Contrast, skewness, kurtosis, deficit moment and mean were not statistically significant(P>0.05). Conclusion: MRI T2WI image texture analysis has certain significance for prediction of PTC cervical lymph node metastasis.

DOI: 10.12117/jccmi.2020.08.012
Objective: To evaluate the changes of left ventricular(LV) systolic function in patients with essential hypertension in early stage by using the longitudinal strain(LS) index of two-dimension(2D) and three-dimensional speckle-tracking echocardiography(3D-STE), and to explore the application value and superiority of 3D-STE. Methods: Thirty-four cases of untreated essential hypertension were collected from 45~65 years old middle-aged people in the hypertension group(H) and 34 healthy volunteers matched in age and sex were collected in the control group(C). Left ventricular posterior wall thickness at end-diastole(LVPWTd), interventricular septal thickness at end-diastole(IVSTd), relative wall thickness(RWT), and left ventricular ejection fraction(2D-EF) were measured. 2D-LS was calculated by 2D-STE. 3D-EF, LV mass index(LVMi), and 3D-LS were calculated by 3D-STE. Results: There was no significant difference in LVPWTd, IVSTd, RWT, 2D-LS, 2D-EF and 3D-EF; 3D-LS was significantly lower(P<0.05) and LVMi was significantly higher(P<0.05) in H than that in C. 3D-LS was positively correlated with 3D-EF(r=0.28, P<0.05), and negatively correlated with SBP, DBP(r=-0.39, P<0.05; r=-0.31, P<0.05). Conclusion: In the middle-aged patients with essential hypertension, the left ventricular systolic function has been reduced when the early left ventricle has not been reconstructed. 3D-LS is more sensitive than 2D-LS to evaluate the left ventricular systolic function in the early stage of hypertension.

DOI: 10.12117/jccmi.2020.08.013
Objective: To explore the diagnostic value and scanning technique of echocardiography in double aortic arch,and analyze the causes of missed diagnosis and improve the accuracy of echocardiography diagnosis. Methods: Echocardiographic features of thirty-one cases of double aortic arch diagnosed by CT or surgery were retrospectively analyzed. Results: Twenty-five cases were diagnosed by echocardiography. Echocardiographic manifestations: In the long axis plane of suprasternal view, the probe was rotated 30° clockwise and 30° anticlockwise along the coronal section of the human body respectively, and the left and right aortic arches were displayed. In the short axial plane of the suprasternal view, two aortic arches on both sides of the trachea could be found(showing cordate changes). Three patients with left arch distal occlusion were misdiagnosed as right aortic arch, and three cases of equilibrium type were missed. Sixteen cases were associated with intracardiac malformation. Fifteen cases with different degrees of airway stenosis. Conclusion: Echocardiography can diagnose the double aortic arch accurately, and it should pay more attention to the continuous scanning and careful exploration of the suprasternal view, which is helpful to improve the accuracy of the double aortic arch ultrasound diagnosis.

DOI: 10.12117/jccmi.2020.08.014
Objective: To explore the value of real-time three-dimensional speckle tracking imaging(RT3D-STI) in the evaluation of left ventricular myocardial strain in left breast cancer patients treated with radiotherapy in early stage. Methods: Totally 37 cases of left breast cancer patients with radiotherapy underwent three dimensional echocardiography. Left ventricular diastolic volume(LVEDV), left ventricular systolic volume(LVESV), left ventricular ejection fraction(LVEF), cardiac output(CO), left ventricular sphericity index(SpI), etc, and left ventricular global longitudinal strain (GLS), left ventricular global circumferential strain(GCS), left ventricular area strain(GAS), left ventricular radial strain(GRS) were acquired by RT3D-STI before and after radiotherapy respectively. The differences of parameters between the two groups were compared. Results: There was no significant difference in LVEDV, LVESV, SV, CO, end-diastolic mass(EDmass), end-systolic mass(ESmass), SpI between the two groups(P>0.05), LVEF was significantly reduced((59.47±4.47) vs. (63.20±4.86), r=2.48, P<0.05). GLS, GCS, GAS, GRS were all decreased after radiotherapy(P<0.05), especially GAS. The correlation coefficients of GLS, GCS, GAS and GRS were r=-0.710, r=-0.645, r=-0.814, respectively(P<0.05), GAS was closely related to GRS. The correlation coefficients of GLS, GCS, GAS, GRS and LVEF were r=-0.653, r=-0.627, r=-0.724, r=0.693, respectively. GAS was closely related to LVEF. Conclusion: In the early stage of the radiotherapy of left breast cancer, RT3D-STI can accurately provide the changes of specific parameters of left ventricular systolic function in different directions when the results of general parameters are in the normal range, and the changes of gas parameters are more valuable, so as to assist clinicians to evaluate the heart damage of patients in the early stage of radiotherapy.

Objective: To investigate the role of 18F-FDG PET/CT in the diagnosis, staging and follow-up of extramammary Paget’s disease(EMPD). Methods: Whole-body 18F-FDG PET/CT images of 13 patients with newly diagnosed or suspected recurrent EMPD were retrospectively analyzed. The lesions with increased uptake of 18F-FDG were positive and were measured with maximum standard uptake(SUVmax). Results: Among the 13 patients with EMPD, 11 received 18F-FDG PET/CT before surgery and 2 received 18F-FDG PET/CT after surgery. Eleven patients had skin lesions, 18F-FDG uptake of all skin lesions was increased in varying degrees, SUVmax ranged from 1.4 to 15.9. The skin lesions thickness was more than or equal to 1 cm in 4 cases(4/11), and SUVmax ranged from 4.6 to 15.9, the thickness was less than 1 cm in 7 cases(7/11), and SUVmax ranged from 1.4 to 3.9. The SUVmax of skin lesions between two groups was compared by independent sample t-test and the results showed that t=2.821, P=0.064, without statistical significance. Lymph node metastasis was found in 7(7/13), and SUVmax ranged from 3.4 to 15.1, and one of them(1/7) was suspected recurrence after EMPD surgery and radiotherapy. In 13 EMPD patients, distant metastasis was found in 2 cases(1 case with single bony metastasis, 1 case with multiple lung, liver and bone metastases), all lesions showed increased FDG uptake in varying degrees and SUVmax ranged from 3.8 to 14.0. Two cases(2/13) of EMPD with lung cancer or colon cancer were found. Conclusion: 18F-FDG PET/CT diagnosis of EMPD mainly depends on the thickness of the lesion, which is more sensitive to the diagnosis of metastasis. Therefore, 18F-FDG PET/CT is very useful for the diagnosis, staging and follow-up of EMPD.

DOI: 10.12117/jccmi.2020.08.016
Objective: To investigate the reference range of the width of fetal cavum septum pellucidum(CSP) at different gestational age and its correlation with gestational age and biparietal diameter, intending to provide a reference basis for clinic. Methods: From January 2018 to May 2019, 1 546 cases of singleton pregnancy without abnormality were collected from the third affiliated hospital of Zhengzhou university for the prenatal ultrasound screening at different gestational age. Logistic regression analysis was used to analyze the change trend of the width of CSP with gestational age and biparietal diameter, Spearman rank correlation coefficient was used to analyze the correlation between the width of CSP and gestational age. Results: In this study, the normal reference range of CSP width was (4.64±1.32) mm, there was a positive correlation(r=0.63, P<0.001) between CSP width and gestational age at 17 to 30 weeks, and there was no significant correlation between CSP width and gestational age at 31 to 37 weeks, the fetal biparietal diameter-to-cavum septum pellucidum ratio(BCR) at 19 to 30 weeks was relatively constant and the reference range was 13.38±3.31. Conclusion: The CSP width is related to the gestational age at 17 to 30 weeks, the BCR is relatively constant at 19 to 30 weeks.

DOI: 10.12117/jccmi.2020.08.017
Objective: To evaluate fetal left ventricular function in patients with pregnancy-induced hypertension by using the tissue Doppler Tei index. Methods: One hundred and thirty pregnant women with hypertension were enrolled, including 84 cases of mild preeclampsia and 46 cases of severe preeclampsia. One hundred and thirty pregnant women with matching gestational age were selected as the control group. Tissue Doppler parameters were measured including isovolumetric time(ICT), isovolumetric relaxation time(IRT) and ejection time(ET), and the Tei index was calculated. Both fetal umbilical arteries spectrum and pregnant women’s uterine arteries spectrum were acquired. Results: There was no significant difference in the Tei index between the mild preeclampsia group and the the control group(P>0.05). There was significant difference in Tei index between severe preeclampsia group and control group and mild preeclampsia group(P<0.05). There was significant difference in the incidence of umbilical artery abnormalities beweeen mild preeclampsia group and severe preeclampsia group(χ2=11.33, P<0.01). There was significant difference in the incidence of early diastolic notch of uterine arteries in pregnant women between mild and severe preeclampsia groups(χ2=8.20, P<0.01). Conclusion: By measuring the tissue Doppler Tei index of fetal left ventricular during pregnancy-induced hypertension, the fetal left ventricular function can be estimated, which can provide clinical diagnosis and treatment basis.

600 Application of dual-layer spectral detector CT in improving the imaging quality of lower extremity arteries
WANG Ning, LIU Zhao-yu
DOI: 10.12117/jccmi.2020.08.018
Objective: To evaluate the application value of the dual-layer spectral detector CT(DLCT) in the CT angiography(CTA) of lower extremity. Methods: Forty-eight patients with suspected lower extremity arterial disease underwent CTA by DLCT. Virtual monoenergetic images(VMIs) were reconstructed at 60 keV to 80 keV with a 5 keV increment. Attenuation, noise, the corresponding contrast noise ratios(CNR), and signal noise ratio(SNR) were assessed in iliac artery, femoral artery, popliteal artery and anterior tibial artery. Comparisons between VMIs and conventional images(CIs) were performed by one-way ANOVA test, and the differences of image quality were compared by Kruskal Wallis H. Results: In CI and VMI studies, 60 keV VMI showed highest subjective score(217 points). CNR and SNR at 60 keV and 65 keV were significantly higher than other VMIs and CIs(P<0.05). Image noise at 60 keV and 65 keV were significantly lower than CIs(P<0.05). The attenuation of each target vessel at 60 keV were significantly higher than that at 65 keV and other level VMIs(P<0.05). Overall image quality was best at 60 keV. Conclusion: VMI level at 60 keV for lower extremity CTA can notably improve the overall image quality and may be using in clinical routine imaging protocols.
