ABSTRACT
Vascular complications after kidney transplantation have been described and pseudoaneurysms represent a well-recognized vascular complication. Although the incidence of pseudoaneurysm is low, it may potentially cause graft loss or may even be fatal for the patients if it is not diagnosed and treated quickly. The authors report a case of renal artery pseudoaneurysm diagnosed two months posttransplantation with cadaveric graft, the treatment and literature data.
ABSTRACT
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.
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.
