Abstract
in English, Portuguese

The ulnar artery is the larger terminal branch of the brachial artery. It originates in the cubital fossa and is covered by the flexor muscles of the forearm. We report an anatomic variant in which the ulnar artery was in a superficial position in the forearm. Since this variant was unknown, an attempted venous puncture injured the artery, causing formation of a pseudoaneurysm.

Resumo: A artéria ulnar é o maior ramo terminal da artéria braquial, ela apresenta origem na fossa cubital e é coberta pelos músculos flexores do antebraço. Reportamos uma variação anatômica, na qual a artéria ulnar situava-se em posição superficial no antebraço. Por falta de conhecimento sobre essa variação, ocorreu a lesão após uma tentativa de punção venosa, a qual levou à formação de um pseudoaneurisma.

Keywords: anatomic variant; pseudoaneurysm; ulnar artery.
