Background: At times, a regulation internal carotid artery-posterior communicating artery junction (ICA-P-Comm) aneurysm becomes a surgical hurdle owing to its close proximity to the anterior clinoid process, an immovable ICA and a concealed dominant P-Comm artery arising from the aneurysm neck.

Method: A 70 year old patient with a low lying ICA-P-Comm aneurysm underwent a "tailored" intradural clinoidectomy for aneurysm clipping.

Conclusion: A tailored anterior clinoidectomy to expose "just enough" allows a proximal ICA control in a suitable area, mobility of an atherosclerotic ICA and exposes the P-Comm artery origin which are essential in safe clipping of these aneurysms.

Purpose: To evaluate the correlation between the degrees of circumferential decompression of the optic canal (OC) and the improvement of visual acuity in patients with parasellar meningiomas (PMs) with optic canal invasion.

Methods: This is a monocentric retrospective study conducted at author's institution. The visual acuity was evaluated preoperative and at 3-months after surgery with Snellen acuity test.

The patient is a 51-year-old woman who had been experiencing syncope and near-syncopal events for at least 10 years with an otherwise benign neurological exam. Magnetic resonance imaging revealed an extra-axial mass consistent with a midline planum and tuberculum sellae meningioma, for which the patient opted to have resected. We demonstrate how performing a posterior orbitotomy with anterior clinoidectomy can enhance a lateral supraorbital craniotomy.

Article Synopsis
  • The study investigates the transorbital approach (TO) for accessing vascular lesions, specifically the carotid and middle cerebral arteries, using cadaveric specimens to understand its feasibility for vascular clipping.
  • Dissection involved a stepwise TO method that included procedures like lateral orbital craniectomy and anterior clinoidectomy, allowing for exposure of various vascular segments and cranial nerves.
  • Findings suggest that the TO approach effectively exposes key artery segments, indicating its potential use in treating paraclinoid and posterior communicating aneurysms.
