A simple tourniquet technique for bleeding control after percutaneous hemodialysis fistula and graft interventions

摘要

The purse-string suture has been widely used for bleeding control after percutaneous interventions through arteriovenous fistula (AVF) and graft (AVG), and it requires suture removal the next day. This study aimed to introduce a simple method using a tourniquet to facilitate hemostasis following AVF or AVG sheath removal after percutaneous procedures. Data were retrospectively collected and included all the consecutive patients who received bleeding control with a tourniquet after percutaneous AVF or AVG interventions. Hemostasis was facilitated using the tourniquet technique after sheath removal. A total of 1966 patients who received the tourniquet technique for bleeding control after percutaneous AVF or AVG interventions were included. Bleeding control was successfully achieved in all patients. Regarding complications, hematoma, thrombosis, and rebleeding occurred in 57 (2.9%), 11 (0.6%), and 8 (0.4%) patients, respectively. Neither pseudoaneurysm nor infection occurred in the patients. Age, gender, pre-existing diseases (including diabetes and hypertension), procedure count, sheath size, hemodialysis access type, and canalization route were similar between patients with and without complications. The primary patency rates at 6,12, 24, and 36?months were 85.0, 64.6, 53.8, and 41.6%, respectively. The tourniquet technique is an effective and safe approach for facilitating hemostasis after catheter-based percutaneous interventions of hemodialysis accesses.
