Iatrogenic arteriovenous fistula in the brachial artery after percutaneous coronary intervention in a patient with end stage kidney disease.

Abstract

Iatrogenic arteriovenous fistula (AVF) is a complication accompanying venous and arterial puncture. Herein we report a case of ligation closure of an iatrogenic AVF in the brachial artery after percutaneous coronary intervention (PCI) for the patient with end-stage kidney disease (ESKD). A 68-year-old woman presented with a history of several coronary angiographies (CAG) and PCI through the right brachial artery. After PCI, the patient experienced a thrill in the right elbow. Two years later, the patient initiated hemodialysis (HD) using a temporary HD catheter for ESKD and congestive cardiac failure. Ultrasonography and computed tomographic angiography revealed an iatrogenic AVF between the right brachial artery and the medial brachial vein. Blood flow in the brachial artery was 760 mL/min. However, the iatrogenic AVF was unusable as vascular access for HD, and prior ligation closure of the iatrogenic AVF was performed, considering the risk of cardiac failure due to double AVFs after the creation of a new AVF for HD. Subsequently, a new radial-cephalic AVF was created in the left forearm. Therefore, clinicians should consider the possibility of iatrogenic AVF in patients with ESKD having a history of CAG or PCI.
