          Abstract

          Paciente do sexo feminino, 73 anos, negra, lavadeira/lavradora, hipertensa, apresentava tumor pulsátil de 1,5 x 0,5 cm em região de tabaqueira anatômica da mão direita há 10 anos, de crescimento lento e progressivo, associado a dor local. Não apresentava alterações neurológicas, cianose de extremidades, sinais de infecção ou trauma local. O teste de Allen resultou negativo, e o Eco-Doppler colorido demonstrou aneurisma de artéria radial na tabaqueira anatômica. Procedeu-se a aneurismectomia de artéria radial na tabaqueira anatômica com ligadura dupla proximal e distal. Houve boa evolução operatória, sem sinais de isquemia digital. O exame anatomopatológico confirmou diagnóstico de parede arterial (aneurisma verdadeiro). O paciente encontra-se em acompanhamento ambulatorial, no momento assintomático. Não há definição de quais aneurismas distais à artéria axilar possam ser acompanhados sem conduta cirúrgica. Como a paciente, neste caso, apresentava teste de Allen normal e dor local, optou-se pela ligadura proximal e distal, com bom resultado.

          Translated abstract

          We report a case of a 73-year-old female, laundress/farmer, hypertensive, with symptomatic pulsatile lump of 1.5 x 0.5 cm at the right anatomical snuffbox of the right hand, with slow and progressive growth and local pain in the past 10 years. The patient presented no neurological symptoms, cyanosis, infection or local trauma history. Allen"s test was negative, and color Doppler ultrasound confirmed presence of radial artery aneurysm in the anatomical snuffbox. Surgical treatment via aneurysmectomy of radial artery in the snuffbox with proximal and distal ligation was carried out. She had good operative course with no signs of digital ischemia. Histopathological test confirmed diagnosis of arterial wall (true aneurysm). She remains asymptomatic in outpatient follow-up. There is no definition as to which aneurysms distal to the axillary artery could be followed without a surgical procedure. As the patients had normal Allen"s test and local pain, proximal and distal ligation was chosen and had good outcome.

          Management of true aneurysms distal to the axillary artery.

          To delineate management strategies and outcomes for true aneurysms involving arteries of the upper extremity distal to the axillary artery. The management of these rare lesions has not been well established in the literature. Retrospective chart review was performed at tertiary referral centers. All patients who received the diagnosis of true upper extremity aneurysms distal to the axillary artery between 1975 and 1995 were included in the review. Nineteen patients were found; seven were excluded because no confirmatory diagnostic imaging study or operative exploration was performed. This represents the largest reported series of true upper extremity arterial aneurysms. Twelve patients (9 men or boys) had 12 confirmed true aneurysms of the brachial or more distal arteries. The average diameters were as follows: brachial artery 4.6 cm, radial artery 2.0 cm, ulnar artery 1.4 cm, and digital artery 0.8 cm. The mean age was 51 years (range, 10 to 86 years). The most common presentation was the presence of a mass. This occurred among eight patients (67%). Four patients (33%) reported pain or paresthesia. One patient (8%) had cold intolerance only. Three patients (25%) had thromboembolic complications. Complications did not consistently correlate with size or presence of intramural thrombus. Three aneurysms (25%) were initially managed nonoperatively and followed for a mean period of 71 months. One of these required operative repair after 5 months because of progressive pain. Ten patients (83%) were treated surgically as follows: five underwent ligation and excision only, and five underwent excision and revascularization. Morbidity was minimal, and there were no perioperative deaths. True arterial aneurysms of the upper extremity distal to the axillary artery are rare and most commonly caused by blunt trauma. Fifty-eight percent of these lesions present with symptoms or complications. Thirty-three percent of asymptomatic lesions later become symptomatic. These factors combined with the minimal morbidity associated with repair suggest that operative repair should be routinely performed for these aneurysms. Revascularization can be performed selectively.

            Idiopathic radial artery aneurysm in the anatomical snuff box.

            An otherwise fit and well 40-year-old left-handed male computer operator presented with a minimally symptomatic lump of 2 years duration in his non-dominant anatomical snuffbox. There was no history of trauma. This was pulsatile and did not transilluminate despite being referred as a ganglion. MRI scan confirmed the presence of a 1.5 cm radial artery aneurysm fed by the radial artery and draining to the second digital artery. In view of his lack of symptoms the patient declined surgical intervention. Literature review reveals radial artery aneurysms to be very rare and usually traumatic in origin. Iatrogenic pseudoaneurysms are widely reported following cannulation. We are unaware of previous descriptions of an idiopathic, isolated radial artery aneurysm.

              True ulnar artery aneurysm of the hand in an 18-month-old boy: a case report.

              True aneurysms of the hand arteries are rare and are exceedingly uncommon in children. Presented is a case of a true ulnar artery aneurysm in an 18-month-old boy in which there was no history of trauma. The aneurysm was resected without reconstruction because of the normal preoperative Allen test result, normal preoperative finger pressure measurement with ulnar artery occlusion, the angiographic evidence that the radial artery was the dominant artery of the hand, and intraoperative evidence of adequate hand perfusion after excluding the aneurysm from the hand circulation as documented by good Doppler signals in all digital arteries.
