Ulnar Artery Aneurysm and Repair

This is a case study of a patient who was presented to the emergency room with ischemia of the left third, fourth and fifth fingers and a pulsatile mass in the hypothenar eminence. Non-invasive arterial exam of the upper extremities was performed bilaterally which resulted in normal pressures and normal blood flow velocities. The arterial duplex imaging was also normal in the subclavian, axillary, brachial, radial and ulnar arteries and also demonstrated triphasic Doppler flow velocities. The technologist scanned distal to the wrist where a branch of the ulnar artery along with the aspect of the palmer arch surface revealed a true aneuryms with both antegrade and retrograde flow. The patient was infused tissue plasminogen activator (TPA) for a total of 72 hours with eventual recanalization of the thrombosed aneurysm. Due to the high risk of limb threat the patient underwent a successful resection of the left ulnar artery aneurysm with vein patch
