Coiling of ruptured pericallosal artery aneurysms

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Vascular Neurology

Background:

• Ruptured pericallosal artery aneurysms pose significant treatment challenges.
• Surgical clipping has traditionally been the primary treatment modality.
• Endovascular coiling offers a less invasive therapeutic option.

Purpose of the Study:

• To evaluate the technical feasibility of treating ruptured pericallosal artery aneurysms using detachable coils.
• To assess the anatomical and clinical outcomes following endovascular coiling.
• To determine if coiling is a viable alternative to surgical intervention.

Main Methods:

• A retrospective review of 12 patients with ruptured pericallosal artery aneurysms treated with detachable coils over 27 months.
• Assessment of clinical presentation (Hunt and Hess grades), concomitant pathologies (hematoma, other aneurysms), and procedural success.
• Clinical and angiographic follow-up to evaluate occlusion, recanalization, and patient outcomes.

Main Results:

• Successful microcatheter access and coil delivery were achieved in all 12 patients.
• No procedure-related complications were reported.
• Initial complete occlusion was achieved in 11 aneurysms; 11 patients had excellent clinical outcomes at follow-up.

Conclusions:

• Endovascular coiling is technically feasible for ruptured pericallosal artery aneurysms.
• Coiling demonstrates promising anatomical and clinical results, comparable to surgical clipping.
• Coiling represents a safe and effective alternative treatment for these challenging aneurysms.
