Abstract: Objective To evaluate value of endovascular stent in treatment of superior vena cava syndrome(SVCS) caused by pulmonary carcinoma.Methods There were ten diagnosed SVCS male patients,aged from 63 to 81.With DSA scanning,the lesion was confirmed and localized through angiography.Appropriate stent was advanced and inserted at a right place.Stents were observed for their positions by fluoroscopy or chest films and patency of blood stream by echo-Doppler during follow-up.Results Initial clinical success was achieved to 100%.Average venous pressure of distal end of SVC decreased from 31.5 cm H2O before and 14.7 cm H2O(P<0.05) after stent insertion,and related clinical symptoms and signs significantly alleviated or disappeared within 2~3 days.No symptoms or signs of stents displacement or pulmonary embolism could be detected during follow-up.Recurrent symptoms of SVCS were found in two cases,one was conduced by thrombosis at the stent three days after operation,and the others were caused by carcinoma progression 90 days after operation.Five cases survived for 11,11,12,14,20 months up to now.Conclusion Percutaneous endovascular stent insertion is a mini-invasive,effective,rapid technique and usually the first choice of treatment for palliation of SVCS.To prolong survival,appropriate treatment of pulmonary carcinoma is important.
