Abstract Objective: To explore the value of color Doppler ultrasound (CDUS) in the thrombolytic therapy for the patient with upper extremity venous thrombosis after peripherally inserted central venous catheter(PICC). Method: Follow-up observation and analysis of 12 patients who underwent PICC due to upper extremity venous thrombosis and received thrombolytic therapy later under CDUS monitoring. Results: In all the 12 patients, 8 patients were male, 4 were female. Seven cases of catheter located in the right upper extremity, 5 cases in the left upper extremity, 4 cases due to gastrointestinal cancer, 3 cases of lung cancer and breast cancer respectively, 2 cases of abdominal malignancies. All the patients with breast cancer were female. In 11 patients the upper extremity venous thrombosis disappeared after thrombolytic therapy. One patient developed extensive upper limb venous thrombosis, and had been suspected clinically to have pulmonary thromboembolism, but excluded later. CDUS can observe the size, shape, scope of the venous thrombosis, also can monitor the situation of flow recanalization, and show the position and the state of the catheter clearly during the whole process of thrombolytic therapy. It would help clinicians to assess the effect of thrombolytic therapy and so as to guide the treatment plan in an large extent. Conclusions: CDUS can accurately observe the location, scope, status of the patients with upper venous thrombosis after PICC and monitor the therapeutic treatment during the whole process. CDFI plays an important role in the assessment of thrombolytic effect for the patients with upper venous thrombosis after PICC and to guide treatment plan.
