A case report of successful using interventional radiology with covered stents for a vascular access-related aneurysm.

Abstract

The etiology of vascular access-related aneurysm (VARA) usually results from repeated cannulation in the same area of the access or caused by inadequate hemostasis after removal of needles during hemodialysis. Surgical management is indicated for the management of compli-cations such as rapid enlargement, overlying skin necrosis, or rupture. Rupture of a VARA is a lethal and requires emergency treatment. The definitive treatment for VARA is surgery, such as vascular repair. However, in cases with arterial bleeding, emergency vascular surgery is difficult to perform. As an alternative, interventional radiology (IVR) has been increasingly used as a minimally invasive and rapid procedure for bleeding arterial lesions. The advan-tages of IVR with covered stents compared with surgery for VARA include a shorter procedure time, lower risk of postoperative peripheral tissue ischemia, and preservation of vascular access (VA), whereas disadvantages include the risk of infection and occlusion and the contraindica-tion of a puncture at the covered stent site. This report pre-sents the case of a patient with a VARA rupture who underwent IVR with a covered stent to preserve VA func-tion and achieved hemostatic efficacy. A 64-year-old female
