Aneurisma sacular da artéria radial: a propósito de um caso clínico

radial artery aneurysms are sporadic and rare, pseudoaneurysms are more common than true aneurysms, mainly in saccular configuration. the etiology is varied and difference from other diagnostics is done by the presence of pulse and thrill. thrombosis and embolization are the main complications, while rupture is rare. from the reported cases of true aneurysms of the radial artery, only one is described as being secondary to repetitive occupational injury, the majority being idiopathic. the authors describe the case of a 63 year old woman, referred to a vascular surgery consultation because of a growing pulsatile mass in the anatomical snuffbox of the left hand. the doppler and angiography studies confirmed the diagnosis of saccular aneurysm of the radial artery, 20 mm on the long axis, with permeable palmar arch and without signs of distal embolization. she underwent a partial aneurysmectomy with ligation and double proximal and distal endoaneurysmorrhaphy. there were no surgical or postoperative complications, particularly ischemic complications. regarding this case, diagnosis and treatment options are discussed.
