Abstract

Aneurysmal venous dilatation is a frequent complication of arterio venous fistulas (AVFs) created for hemodialysis. Venous aneurysm rupture can lead to lethal hemorrhage. A 49-year-old male patient presented with a giant aneurysmal dilatation of his AVF 10 years after its creation. The patient had complaints of pulsating pain and discomfort due to swelling of the left forearm. We performed an aneurysm resection and revised the overlying dermal lesion through a brachial plexus block. Here, we describe the pathological features of the arterialized venous aneurysm compared to simple venous aneurysms.
