Resumo

Resumo: A ultrassonografia vascular com Doppler é um método não invasivo útil no diagnóstico e planejamento terapêutico da doença oclusiva das artérias podais. A artéria pediosa dorsal é a continuação direta da artéria tibial anterior e tem trajeto retilíneo no dorso do pé, dirigindo-se medialmente ao primeiro espaço intermetatarsiano, onde dá origem a seus ramos terminais. A artéria tibial posterior distalmente ao maléolo medial se bifurca e dá origem às artérias plantar lateral e plantar medial. A plantar medial apresenta menor calibre e segue medialmente na planta do pé, enquanto a plantar lateral é mais calibrosa, seguindo um curso lateral na região plantar e formando o arco plantar profundo, o qual se anastomosa com a artéria pediosa dorsal através da artéria plantar profunda. A avaliação das artérias podais pode ser realizada de maneira não invasiva com exame de eco-Doppler, com adequado nível de detalhamento anatômico.

Abstract

Vascular Doppler ultrasound is a noninvasive method that can help in diagnostic and therapeutic planning in case of pedal arterial obstructive disease. The dorsalis pedis artery is the direct continuation of the anterior tibial artery and follows a straight course along the dorsum of the foot, leading medially to the first intermetatarsal space, where it gives off its terminal branches. The posterior tibial artery forks distal to the medial malleolus and gives rise to the lateral plantar and medial plantar arteries. The medial plantar artery has a smaller caliber and runs medially in the sole of the foot, while the lateral plantar artery is of larger caliber, following a lateral course in the plantar region and forming the deep plantar arch, which anastomoses with the dorsalis pedis artery via the deep plantar artery. The arteries of the foot can be assessed noninvasively with Doppler, providing an adequate level of anatomical detail.
