Resolution of unilateral obstructive hydrocephalus complicating expanding thrombosed basilar apex aneurysm after anticoagulation treatment

Trans-lateral ventricular approach for surgical treatment of a high located basilar apex aneurysm: report of a rare presentation of the disease and surgical technique

Surgical management of basilar apex aneurysms is considered among the most technically challenging procedures and high located basilar apex makes the procedure more challenging. Pterional trans-sylvian (with or without orbitozygomatic extension) and subtemporal are the most commonly used approaches, however, it is sometimes difficult or impossible to access a high-positioned aneurysm of basilar bifurcation without excessive retraction of brain and neurovascular structures. We are reporting a 65-year-old woman presented with chronic hydrocephalus secondary to a high-located basilar apex aneurysm surgically clipped through trans-frontal trans-ventricular trans-choroidal approach. We described anatomical details for selecting this approach and surgical steps during the procedure.

Dementia resulting from expansion of basilar artery aneurysm: two case reports and a review of the literature

BACKGROUND

Dementia places a large burden on the economy, with financial and emotional costs incurred by patients, caregivers and the health sector.

METHODS AND RESULTS

We report the first published case series of giant basilar aneurysm leading to progressive cognitive and functional decline. We review the literature regarding giant aneurysms and their association with dementia and the possible underlying pathophysiological mechanism.

CONCLUSIONS

This report highlights a number of therapeutic considerations when determining the best management strategy for these difficult lesions.
