ABSTRACT
False aneurysm is one of the complications of untreated arterial injury. Most traumatic aneurysms in the extremities are false, and they are usually caused by penetrating trauma. The pathogenesis of false aneurysm is initiated by a damaged artery that allows hemorrhage into surrounding soft tissue, an encapsulated hematoma is then formed, which undergoes organization, with invasion of fibrin and con-nective tissue, and the endothelialization of its central cavity, which communicates with the arterial defect, forming the false aneurysm. We experienced two cases of traumatic false anerysm of a left anterior tibial artery and a right radial artery, which were treated successfully by end-to-end anastomosis in the former and a saphenous vein graft in the latter.

An aneurysm in the upper extremity is rarer than in the lower extremity, and a traumatic false aneurysm is very rare. We encountered two patients with a traumatic false aneurysm in the upper extremity. The first case developed from a posterior interosseous artery injury after an internal fixation using a plate and circumferential wiring for a comminuted fracture of the proximal shaft of radius associated with a dislocation of the left elbow joint. This patient was managed by excision of the false aneurysm, and ligation of the artery. The second case developed from a radial artery catheterization on the left wrist. This was managed by excision of the false aneurysm and an end-to-end anastomosis and resulted in the disappearance of the false aneurysm and a good vascular patency. We report two rare cases of traumatic false aneurysm in the upper extremity and a review of the literature.

Two cases of iatrogenically induced false aneurysm of the superficial temporal artery are presented. One patient showed partially filled aneurysmal sac, 1x1 cm sized, on the main trunk of left superficial temporal artery by external carotid artery angiography. Another patient showed aneurysmal dilatation, 3x2 cm sized, of the superficial temporal artery with direct injection of Urograffin into the pulsatile mass. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.
