Superior vena cava (SVC) syndrome is a disabling and potentially life-threatening complication. SVC revascularization can be achieved by means of endovascular or direct surgical reconstructions. In the patient on whom we report, these two options were not possible, and a peripheral venous bypass grafting procedure was done with a technical innovation. Right upper-extremity swelling developed in a 55-year-old woman after radiation therapy for lung carcinoma. A left subclavian vein Port-A-Cath induced extensive thrombosis of the left innominate, axillosubclavian, and jugular veins. She was referred to our institution with very symptomatic SVC syndrome after two failed endovascular interventions. The occlusion of both innominate veins and chronic thrombus extending into the left axillosubclavian and internal jugular veins was confirmed by means of a venogram. A third endovascular attempt failed. The presternal skin had severe radiation-induced damage precluding direct SVC reconstruction. A bypass grafting procedure from the right internal jugular to the femoral vein was performed with spliced bilateral greater saphenous veins tunneled inside an externally supported expanded polytetrafluoroethylene graft. Postoperatively, the patient had no symptoms, and graft patency was confirmed by means of duplex ultrasound scanning. A saphenojugular bypass grafting procedure can offer prompt and durable relief of SVC syndrome when endovascular or direct surgical reconstructions are not possible. This rarely used peripheral venous bypass grafting procedure was modified by tunneling the vein graft inside an externally supported polytetrafluoroethylene graft to prevent kinking or compression.
上腔静脉(SVC)综合征是一种致残且可能危及生命的并发症。SVC血运重建可通过血管内或直接手术重建来实现。在我们所报告的该患者中,这两种选择均不可行,于是采用了一项技术创新进行外周静脉旁路移植术。一名55岁女性在接受肺癌放射治疗后出现右上肢肿胀。左锁骨下静脉植入式静脉输液港导致左无名静脉、腋锁骨下静脉和颈静脉广泛血栓形成。在两次血管内介入治疗失败后,她因症状严重的SVC综合征被转诊至我院。通过静脉造影证实双侧无名静脉闭塞以及慢性血栓延伸至左腋锁骨下静脉和颈内静脉。第三次血管内介入尝试失败。胸骨前皮肤有严重的放射损伤,无法进行直接的SVC重建。采用双侧大隐静脉拼接后经外部支撑的膨体聚四氟乙烯移植物隧道化,进行了从右颈内静脉到股静脉的旁路移植术。术后,患者无症状,通过双功超声扫描证实移植物通畅。当无法进行血管内或直接手术重建时,隐颈旁路移植术可迅速且持久地缓解SVC综合征。这种很少使用的外周静脉旁路移植术通过将静脉移植物经外部支撑的聚四氟乙烯移植物隧道化进行改良,以防止扭结或受压。
