Paciente do sexo feminino, 73 anos, negra, lavadeira/lavradora, hipertensa, apresentava tumor puls芍til de 1,5 x 0,5 cm em regi o de tabaqueira anat mica da m o direita h芍 10 anos, de crescimento lento e progressivo, associado a dor local. N o apresentava altera es neurol車gicas, cianose de extremidades, sinais de infec o ou trauma local. O teste de Allen resultou negativo, e o Eco-Doppler colorido demonstrou aneurisma de art谷ria radial na tabaqueira anat mica. Procedeu-se a aneurismectomia de art谷ria radial na tabaqueira anat mica com ligadura dupla proximal e distal. Houve boa evolu o operat車ria, sem sinais de isquemia digital. O exame anatomopatol車gico confirmou diagn車stico de parede arterial (aneurisma verdadeiro). O paciente encontra-se em acompanhamento ambulatorial, no momento assintom芍tico. N o h芍 defini o de quais aneurismas distais 角 art谷ria axilar possam ser acompanhados sem conduta cir迆rgica. Como a paciente, neste caso, apresentava teste de Allen normal e dor local, optou-se pela ligadura proximal e distal, com bom resultado. 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%26quot;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%26quot;s test and local pain, proximal and distal ligation was chosen and had good outcome.
