Treatment of arteriovenous access pseudoaneurysms using ultrasound guided balloon assisted thrombin injection: Two cases and systematic review of the literature

Arteriovenous fistula pseudoaneurysm (AVF-PSA) is a common complication, usually caused during dialysis cannulation, which traditionally has been treated with open and less frequently endovascular techniques. Thrombin injection, although established in the treatment of arterial pseudoaneurysms, has barely been used in the treatment of AVF-PSA, due to concerns for AVF thrombosis or proximal embolization.
