Giant Pseudoaneurysm as a delayed Surgical Complication in a Patient Operated on a Giant Neuroma of the Vagus Nerve: Case Report and Management Considerations

Abstract

The vertebral artery has four segments. The horizontal portion of the V3 segment is the most exposed portion of the vertebral artery to potential iatrogenic injuries during surgical approaches to the posterior fossa. We present an unusual case of a patient who was operated on a giant neuroma of the left vagus nerve, with incidental vertebral artery iatrogenic injury, the development of a delayed giant pseudoaneurysm, and the treatment for this complication. We conclude that endovascular treatment may be a good option for the management of this serious surgical complication.

Resumo

A artéria vertebral tem quarto segmentos. A porção horizontal do segmento V3 é a mais exposta a potenciais lesões iatrogênicas durante procedimento cirúrgico de acesso à fossa posterior. Apresentamos caso incomum de paciente submetido à cirurgia para neuroma gigante no nervo vago esquerdo, com acidental lesão da artéria vertebral iatrogênica, desenvolvimento de posterior pseudoaneurisma gigante e tratamento para esta complicação. Concluímos que o tratamento endovascular pode ser uma boa opção para o cuidado desta grave complicação cirúrgica.
