Abstract

A 47-year-old male presented with a right-sided Shamblin type 2 carotid body tumor measuring 5*5 cm. After preoperative embolization, a sub adventitial resection of the tumor was done. He was discharged after postoperative day 5 and presented again to emergency 10 days later with a bleeding pseudoaneurysm at the surgical site causing dysphagia and dyspnea. He was taken for emergency exploration of the surgical wound and, intraoperatively, it was observed that the proximal ends of the internal carotid artery and external carotid artery close to the bifurcation were forming a pseudoaneurysm, 1 cm distal to the common carotid artery. The external carotid artery was ligated and a common carotid to internal carotid artery bypass was done with a reversed saphenous vein graft. He recovered well in the postoperative period and was discharged on day 7. Pseudoaneurysm formation following carotid body tumor resection is extremely rare and has only been reported thrice in the literature.

Keywords

Resumo

Um homem de 47 anos apresentou tumor carotídeo Shamblin tipo 2 no lado direito, medindo 5 x 5 cm. Após embolização pré-operatória, foi realizada ressecção subadventicial do tumor. O paciente teve alta no quinto dia pós-operatório e voltou à emergência 10 dias depois, com pseudoaneurisma hemorrágico no sítio operatório causando disfagia e dispneia. Foi levado para exploração emergencial da ferida cirúrgica, e, no intraoperatório, 1 cm distalmente à artéria carótida comum, as extremidades proximais da artéria carótida interna e da artéria carótida externa próximas à bifurcação formavam um pseudoaneurisma. A artéria carótida externa foi ligada, e foi realizada uma ponte de safena de carótida comum para a artéria carótida interna com a veia safena invertida. O paciente se recuperou bem no pós-operatório e recebeu alta no sétimo dia. A formação de pseudoaneurisma após ressecção de tumor do corpo carotídeo é extremamente rara, tendo sido relatada apenas três vezes na literatura.
