Interventional treatment and imaging diagnosis of Cockett's syndrome / 介入放射学杂志

Objective To evaluate the imaging diagnosis and select rational interventional treatment for Cockett's syndrome. Methods Clinical analyses and retrospective studies were carried out for 14 cases with Cockett's syndrome in the past five years. Results Three cases of simple Cockett's syndrome and 2 cases of varicose veins showed obvious curable efficacy. In 2 cases of synthetically interventional treatment, 1 case showed no relapse after long-term follow-up of 24 months, another developed acute thrombosis again two weeks later but with a further recurrence after a successful thrombolysis; and then the patient was undergone vascular graft bypass and temporary arteriovenous shunt. Conclusions Through proper and prompt evaluation of stenotic and hemadynamic changes of the iliac and femoral veins giving a complete picture of the pathophysiology, whould lead to a successful treatment for cocketts syndrome especialy before the venous thombosis, and in turn would greatly reduce the late stage complications.

Percutaneous transluminal angioplasty with stenting for treatment of superior vena cava obstructive syndrome / 介入放射学杂志

Objective To evaluate the clinical value of percutaneous transluminal angioplasty with stenting(PTAS) for the treatment of superior vana cava obstructive syndrome (SVCOS). Methods 15 cases of SVCOS including 10 cases of lung cancer with mediastinal lymphatic metastasis, 3 cases as malignant lymphoma and 2 cases of esophageal cancer with mediastinal lymphadenopathy, were undergone right subclavian vein or ellow vein catheterization for pressure measurement and DSA imaging of SVC with displaying the obstructive characteristics. A self expanding stent was then implanted throwgh right fermoral vein catheterization.Results 15 cases were all successfully undertaken angioplasty and stenting, except 1 case with a long stricture over 10 cm requiring 2 stents. After successful stent placement, DSA revealed smooth flow of contrast with almost normal diameter of SVC lumen, together with disappearance or relief of SVCOS. The SVC pressure decreased from 30.5?2.3 cmH 2O down to 8.8?1.5 cmH 2O after recanalization, with a significant difference in statistics( P
