Abstract

Ulnar artery aneurysms are quite rare discoveries, related to repetitive trauma, vasculitis, anatomic abnormalities, or infections. Typically caused by blunt injury to the ulnar artery and superficial palmar arch, arterial wall damage leads to the formation of an aneurysm. The sensory branch of the ulnar nerve becomes compressed, causing paraesthesia and weakness along the 4th and 5th digits, and resection is required. It is interesting to note, in this particular case, that a high origin and superficial ulnar artery coursed along the forearm and entered along the ulnar side of the hand. A diagnostic and therapeutic approach is necessary to relieve ulnar nerve entrapment. In addition, it is important to establish an early diagnosis prior to any surgical procedures in order to isolate and establish continuous flow to the compromised region. Further studies are required, however, to establish an evidenced-based approach to such anatomic variations with surgical repair.

Highlights

Aneurysmal formations, from excessive dilatation, occurs secondary to damage of blood vessel walls
Aneurysms of the ulnar artery and palmar arch, related to repetitive trauma of the upper extremity, arise from rare circumstances, which affect the hypothenar region of the hand
Most traumatic aneurysms are quite common among young males, and sometimes related to congenital abnormalities or infections

Summary

Introduction

Aneurysmal formations, from excessive dilatation, occurs secondary to damage of blood vessel walls. Aneurysms of the ulnar artery and palmar arch, related to repetitive trauma of the upper extremity, arise from rare circumstances, which affect the hypothenar region of the hand. Most traumatic aneurysms are quite common among young males, and sometimes related to congenital abnormalities or infections. In this particular case, a 73-year-old woman underwent an aneurysmal repair after minor trauma and suffered numbness and tingling along the 4th and 5th digits of the right hand. Duplex ultrasound and AV Fistulogram identified an aneurysm a superficial ulnar artery, lying adjacent to the aneurysm. Knowledge of such variations allows for improved care in the fields of radiology, angiography, surgery and the medical sciences
