Pseudoaneurysm in Deep Palmar Arch of the Hand

Abstract

Full-thickness traumatic disruption of the normal arterial wall is the leading cause of pseudoaneurysms. Pseudoaneurysms in the upper extremity especially the deep palmar arch of the hand are rare. A 17 year-old boy developed a pesudoaneurysm in his deep palmar arch of right hand after sustaining multiple penetrating wounds. The symptoms and signs were suggestive of the diagnosis of the psendoaneurysim and was confirmed by color Doppler ultrasonography preoperatively. Total excision of the pseudo- aneurysm was performed with intraoperative evaluation of arterial circulation due to the multiple penetrating injury to the vessles and delayed diagnosis. Characteristic of pseudoaneurysms of hand and upper extremity are reviewed with further discussions on diagnostic modalities and treatment options.
