上、下腔静脉阻塞综合征的诊断与治疗（病例报告及文献复习）

上、下腔静脉阻塞综合征很罕见，其诊断及治疗很困难。我们报告的病例，经皮球囊成形术治疗成功。治疗前后下腔静脉跨狭窄部压力阶差由５．３３ｋＰａ（４０ｍｍＨｇ）下降至０．５３ｋＰａ（４ｍｍＨｇ），１周后临床症状明显改善。根据我们的体会及文献复习，正确诊断上、下腔静脉综合征对治疗方式的选择极为重要。经皮血管成形术及血管内支架对上、下腔静脉综合征是一种安全、有效的治疗手段，仅在无血管内支架适应症时，才考虑外科手术。

Diagnosis and Treatment of Superior Vena Cava Syndrome Associated with Inferior Vena Cava Syndrome:A Case Report and Literature Review.

Superior vena cava syndrome(SVCS)associated with inferior vena cava syndrome(IVCS)is extremely rare,Both diagnosis and treatment for the syndrome are very difficult.A case of SVCS associated with IVCS successfully managed by percutaneous transluminal angioplasty(PTA)is reported,Before PTA,translesional pressure gradient was 5.33 kPa(40 mmHg).After PTA,the gradient was 0.53 kPa(4mmHg).The clinical symptoms was improved after the treatment.This report suggests that PTA is a safe,effetive procedure for patients with SCVS associated with IVCS.
