A case of intraoperative observation of maxillary artery aneurysm

Abstract

The maxillary artery aneurysm occurs rarely, only a few cases were described in the foreign literature where the aneurysm were associated mainly with the past head injury. The behavior of the aneurysm is largely unknown: both spontaneous resolution and growth of the aneurysm, resulting in rupture, have been reported. We observed an aneurysm of the maxillary artery in the maxillary sinus as an intraoperative finding, with the following bleeding and embolization of the bleeding vessel. Due to the growing number of endovideoscopic operations on the axillary system, it was proposed to increase the volume of preoperative examination to prevent the intraoperative bleeding.
