Resumo

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.

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.
