Thrombosis related to true axillo-brachial arterial aneurysm following ligation of longstanding arteriovenous fistula for hemodialysis.

A 52-year-old man who had received hemodialysis via a left radial-cephalic arteriovenous fistula (AVF) for 18 years presented with severe ischemic symptoms in the left upper arm 12 years after occlusion of the AVF. Diagnostic imaging revealed thrombotic occlusion from a left axillary-brachial artery aneurysm, which required distal bypass surgery. The inflow artery of an AVF can develop aneurysmal degeneration, resulting in upper limb ischemia by embolization or decreased flow, especially with a ligated or occluded AVF or immunosuppressive therapy after renal transplantation. In such cases, the AVF should be monitored, even if ligated or occluded.

Thoracic Endovascular Aortic Repair With Subclavian Revascularization for Symptomatic Nonaneurysmal Aberrant Right Subclavian Artery.

Aberrant right subclavian artery is a common aortic arch anomaly that can cause dysphagia as a result of compression by the aberrant artery. For patients with an aneurysm associated with an aberrant right subclavian artery, surgical or endovascular intervention is a well-described treatment. However, for patients with a nonaneurysmal aberrant right subclavian artery, treatment with thoracic endovascular aortic repair has been limited. We describe the use of thoracic endovascular aortic repair and subclavian revascularization to treat esophageal stricture in a patient with a symptomatic nonaneurysmal aberrant right subclavian artery. The patient's dysphagia was successfully relieved after the operation.

Congenital absence of left common and external iliac arteries.

Congenital atresia of the common and external iliac arteries is an extremely rare vascular anomaly, although often associated with limb ischemia and genitourinary malformations. We have presented a rare case of the congenital absence of the left common and external iliac arteries, with no limb ischemic symptoms or organ anomalies present.
