Venous hypertension and outflow stenosis of arteriovenous hemodialysis access managed using endovascular procedures usually present a high technical success rate, with few complications. We reported a rare and fatal complication of superior vena cava perforation with pericardial tamponade 3 months after subclavian vein stenting. Interventional recanalization with stenting for the management of superior vena cava syndrome or central vein stenosis is a safe procedure with a low complication rate. Stent misplacement, reocclusion, migration, or access-related complications appear to occur most frequently.

Ligation and division of the saphenofemoral junction (L/D SFJ) can protect against the danger of venous thromboembolism (VTE) associated with greater saphenous vein (GSV) radiofrequency ablation (RFA). Although this procedure is regarded as clean from an infection standpoint, surgical site infection (SSI) can offset its thromboembolic benefit. We questioned whether SSI associated with L/D SFJ could be minimized by a single preoperative dose of antibiotic. ⋯ L/D SFJ combined with RFA of the GSV, when treated as a clean procedure and not prophylaxed with antibiotic, carries a significant risk of SSI. While diabetes and high body mass index are patient-associated SSI risk factors, a single dose of preoperative antibiotic significantly reduces the rate of all infection, eliminates the danger of serious infection, and is associated with minimal VTE.
