Vascular Insufficiency/Chronic Ischemia in the Upper Extremity-Reconstruction for Ulnar Artery Aneurysm at the Wrist

Reconstruction for Ulnar Artery Aneurysm at the Wrist

Pdf Summary

This document describes the surgical technique for reconstructing ulnar artery aneurysms at the wrist. Ulnar artery aneurysms are most commonly caused by hypothenar hammer syndrome, which occurs due to repetitive trauma to the hand. The standard approach is open exploration of the palm followed by excision of the aneurysmal segment. The aneurysm is then reconstructed using either vein or arterial grafts to bridge the arterial gap. Digital ischemia is relieved by the arterial reconstruction. Common symptoms include pain, cyanosis, pallor, coolness, and recurrent episodes of vasospasm. Diagnostic tests such as duplex studies and contrast arteriography are performed to visualize the aneurysm and determine the need for reconstruction. Surgical anatomy of the ulnar artery is described, including its passage through Guyon's canal. The surgical technique involves making an incision on the ulnar volar wrist, exposing the ulnar artery, excising the aneurysm, and examining the artery for any damage. If the gap between the arterial ends is too great for direct repair, vein or arterial grafts are used for reconstruction. The document also discusses the potential complications and outcomes of ulnar artery reconstruction surgery.
