HUANG Xin-wen;LV Hong-bin;LAN Yong-shu;TANG Guang-cai;LI Chun-zhi
DOI:
Objective: To investigate CT features of the orbit of Graves’ disease(GD) and explore the value of CT in clinical diagnosis and treatment in patient with GD. Methods: The manifestations of CT scan in 68 cases(136 orbits) with GD were studied in respect to the size and density of the extraocular muscles, exophthalmos and other manifestations. Results: The extraocular muscles in patients with GD were significantly larger than those in normal person (all P<0.05). Among the enlarged extraocular muscles, medial rectus was more frequently involved(67.6%), inferior rectus(58.8%) and superior rectus(45.6%) were the next, the last was lateral rectus(30.9%). In all 136 eyes, there were 118 eyes with exophthalmos. Among the 118 eyes with exophthalmos, there were 97 eyes with degree I exophthalmos and 21 eyes with degree Ⅱ exophthalmos. The detecting rate of exophthalmos was 86.8% in CT, but 66.9% in clinical diagnosis. The density change of the extraocular muscles and other characteristic manifestations were found in patients with GD. Conclusion: Orbital CT scan can become a routine examination and can be useful to clinical diagnosis and treatment in patients with Graves’ ophthalmopathy(GO).

CHEN Ran;YANG Jun;REN Wei-dong;MA Chun-yan
DOI:
Objective: To assess systolic and diastolic function of right ventricle in patients with pulmonary hypertension by Doppler tissue imaging(DTI) technique. Methods: The patients with pulmonary hypertension were divided into three groups. The motion of tricuspid annular of patients were analyzed by DTI and the velocity of anterior, septal and posterior of tricuspid annular, systolic velocity(Sa), early diastolic velocity(Ea), late diastolic velocity(Aa), were measured. Meanwhile, these parameters were compared with control group. Results: Compared with control group, Sa of anterior and septal tricuspid annular were decreased in groupⅡ, Ⅲ(P<0.05). In group Ⅲ, Sa of anterior tricuspid annular was worse than groupⅠ(P<0.05). Sa of posterior tricuspid annular, Ea of anterior tricuspid annular were lower than those of control group(P<0.05). Meanwhile, Ea of septal tricuspid annular were lower than those of normal group and groupⅠ(P<0.05). In group Ⅲ, Aa and Ea/Aa of septal and posterior tricuspid annular were lower than those of normal group(P<0.05). In groupⅡ and Ⅲ, Ea/Aa of anterior tricuspid annular were lower than those of control group(P<0.05). Conclusion: Pulmonary hypertension lead to moderate or severe dysfunction of right ventricle, systolic dysfunction was involved earlier than those of diastolic function.

XU Dong-mei;FAN Chong-lun;ZHANG Mei;ZHANG Yun
DOI:
Objective: To analyse the correlation of parameters between left ventricular systolic function, functional class, and the systolic and diastolic function of left ventricle before and after treatment by Doppler tissue imaging(DTI). Methods: Thirty-four consecutive patients with a clinical diagnosis of congestive heart failure were studied by DTI. Four sites at mitral annuli were selected corresponding to the septal, lateral, anterior and inferior walls of the ventrical from apical 4- and 2-chamber views. We detected wall motion of mitral valve annulus and recorded DTI indexes included the peak systolic velocities(Sa), the peak early and late diastolic velocities(Ea and Aa). Sa/Ea and VMS were calculated. Thirty-four normal subjects were selected as control group. Results: Sa derived from the lateral site of mitral annulus from apical four-chamber view correlated well with functional class(rs=-0.65, P<0.0001), the 4-site average velocities of mitral annulus correlated better with functional class(rs=-0.69, P<0.0001). Compared with healthy controls, Sa and Ea of all 4 sites were significantly decreased(P<0.001), Ea/Sa significantly increased(P<0.01). After treatment, Sa and Ea of all 4 sites were significantly increased(P<0.001), Ea/Sa significantly decreased(P<0.01). Conclusions: Left ventricular systolic and diastolic function could be quantitatively analyzed by DTI, there are more close correlation between the 4-site average velocities of mitral annulus VMS and NYHA functional class.

DOI:
Objective: This study reports our clinical experience of interventional treatment of multi-fenestrated atrial septal defect(ASD) under echocardiography. Methods: From December 1998 to March 2005, 11 patients, 2 males, 9 females, with mean age of 26.1±4.2 years(ranged from 4 to 60 years old), underwent percutaneous closure of multi-fenestrated ASD. Out of the 11 patients, 8 had two defects, 2 had three defects, 1 had four defects. Two of the 11 patients associated with atrial septal aneurysm, one with atrial fibrillation and hydropericardium. The frequency of detecting probe used was 2.5MHz and 5.0MHz respectively. Diagnosis was determined with transthoracic or transesophageal echocardiography before procedure, procedure was performed under support of transesophageal echocardiography. Transthoracic echocardiography(TTE) was used on the second day after the procedure and during follow-up. TTE mainly observed in parasternal, cardiac apical, inferior xiphoid process four chamber view, and inferior xiphoid process couple atrium, great artery minor axial views, and TEE mainly reviewed in atrial septal long axis, superior vena cava long axis, inferior vena cava, great artery minor axis, four chamber view. Results: Nine of the 11 patients were successfully treated with single occluder(device size ranged from 12 to 40mm), two were implanted with two devices for effective closure of all defects(occluder diameter 18 and 8mm). During follow-up, residual shunting was observed in two of the 11 patients, and no other complications were noted. Conclusions: Multi-fenestrated ASDs should be closed under transesophageal echocardiographic guidance to determine number, diameter and distance of ASDs. We should try our best to close multi-fenestrated ASDs with one device.

GAO Zai-rong;ZHU Hong-yan;ZHANG Jun;LI Zhen-qiong;LIU Jian-she;ZHANG Yong-xue;ZHU Zhong-hua
DOI:
Objective: To analyze the relation between renal dynamic imaging and pathological changes in IgA nephropathy (IgAN). Methods: Sixty-seven histologically confirmed patients with IgAN were included in this study. According to the extent of renal pathological changes, such as glomerular lesions, tubulo-interstitial lesions and vessel lesions, all patients were divided into several groups according to Katafuchi’s score system and Lee’s histological classification. All of the 67 patients underwent renal dynamic imaging with 99mTc-DTPA (diethylenetriaminepentaacetic acid). And the imaging parameters including perfusion index(PI), glomerular filtration rate(GFR) and 20min clearance(C20) were calculated. The relationship between pathological Katafuchi’s scores and imaging parameters among all Lee’s groups were analyzed. Results: The results indicated that there was a positive correlation between PI and the vessel lesion score (P<0.01), negative correlation between GFR and the glomerular lesion score (P<0.01) and tubulo-interstitial lesion score (P<0.05), and negative correlation between C20 and tubulo-interstitial lesion score (P<0.05). With the Lee’s grade increasing, GFR and C20 gradually decreased, and PI increased. The differences of these imaging parameters among Lee’s groups were significant(P<0.05). Conclusion: The results of renal dynamic imaging closely relate to the renal pathological changes of IgAN, and can better reflect the degree of pathological lesions. Renal dynamic imaging is of practical value in the decision of therapy procedure and evaluation of prognosis of IgAN.

ZHANG Hai-shen;WANG Yong;YANG Yi-jun;ZHONG Tao;HUANG Ping-bo
DOI:
Objective: To study CT characteristics of giant lymph node hyperplasia and their pathologic basis. Methods: Seven cases of pathologically proved giant lymph node hyperplasia were examined by plain and enhanced CT scanning. Results: In 5 cases with localized type of giant lymph node hyperplasia, which belonged to hyaline vascular type pathologically, the lesion presented as a solitary round or oval, iso-density soft tissue mass with smooth border. After contrast administration, obvious homogeneous sustaining enhancement was observed. The 2 cases with disseminated type, belonged to plasma cell type pathologically, the lesion presented as many dissimilar size nodules, inhomogeneous density, indistinct border, the periphery fat plane was fuzzy, with mild moderate non-uniform enhancement, 1 case showed incomplete ring-like enhancement. Conclusion: CT findings of giant lymph node hyperplasia are closely associated with its pathology. For localized type(hyaline vascular type), it is possible to make a correct diagnosis preoperatively. For disseminated type(plasma cell type) carries no specific CT signs, its verification is mainly based on pathologic examination.
