Although endovascular management has been increasingly adopted for basilar apex aneurysms (BAAs), microsurgery still represents an amenable treatment option. In this case series, six female patients (median age: 46 years) with six saccular high-riding BAAs (50% ruptured) were included. The median neck size was 5.

Article Synopsis
  • Posterior communicating artery (PCoA) aneurysms account for about 15-25% of intracranial aneurysms and come with a 44% rupture risk, complicating surgical procedures due to limited visibility.
  • A case is presented involving a 54-year-old woman who experienced severe headaches, vomiting, and a loss of consciousness, leading to a diagnosis of a PCoA aneurysm via imaging after a subarachnoid hemorrhage.
  • She successfully underwent a right minipterional craniotomy with exoscopic clipping, which provided high-quality images and improved ergonomics during surgery, resulting in her significant recovery within three days post-operation.

Background And Objective: Aneurysms of the posterior cerebral circulation constitute a burdensome condition with high mortality and morbidity. In the modern era, there has been a trend toward favoring an endovascular approach over microsurgery for aneurysm cases. Nevertheless, this transition has yet to be mirrored in low-to-middle-income countries where endovascular therapy may not be widely available.

Background: The microscope is important in neurosurgery, but it is not exempt from limitations. The exoscope has emerged as an alternative because it offers better 3-dimensional (3D) visualization and better ergonomics. We present our initial experience in vascular pathology using 3D exoscopy at the Dos de Mayo National Hospital to show the viability of the 3D exoscope in vascular microsurgery.
