Resumo

Os autores relatam um caso de tumor de corpo carotídeo (paraganglioma) em um paciente de 74 anos de idade, submetido a embolização intra-arterial com micropartículas esféricas, de polivinil acetato, com casca de polivinil álcool (PVAc + PVA), previamente à ressecção do tumor. O estudo angiográfico demonstrou massa altamente vascularizada na bifurcação carotídea esquerda, sendo a embolização pré-operatória utilizada no intuito de diminuir a vascularização e reduzir a perda sangüínea, aumentando a segurança do tratamento cirúrgico. O estudo histopatológico confirmou a presença de trombose e isquemia tecidual.

Abstract

The authors report a case of carotid body tumor (paraganglioma) in a 74-year-old male patient, submitted to intraarterial embolization with spherical core/shield polyvinyl acetate and polyvinyl alcohol (PVAc + PVA) microparticles prior to surgical excision. Angiography has demonstrated a highly vascularized mass in the left carotid bifurcation, and preoperative embolization was used in order to decrease vascularity, reduce blood loss and improve safety of surgical treatment. Microscopic study confirmed presence of thrombosis and tissue ischemia.
