Revascularization with saphenous vein bypasses for complex intracranial aneurysms

Area of Science:

• Neurosurgery
• Vascular Surgery
• Cerebrovascular Disease

Background:

• Intracranial aneurysms are typically managed with microsurgical clipping or endovascular coiling.
• Complex aneurysms with unusual anatomy or morphology may necessitate revascularization strategies.

Purpose of the Study:

• To review the indications, surgical techniques, and clinical management of saphenous vein bypasses for complex intracranial aneurysms.
• To highlight the role of bypass in treating aneurysms that require parent artery sacrifice.

Main Methods:

• Review of cases involving saphenous vein bypasses for intracranial aneurysms performed by the senior author.
• Analysis of 110 total bypasses, with 46 for aneurysms, including 22 high-flow extracranial-to-intracranial saphenous vein grafts.

Main Results:

• Saphenous vein bypasses were utilized for complex aneurysms unsuitable for conventional treatments.
• Sixteen of the 22 saphenous vein graft bypasses were for giant intracranial aneurysms.
• The technique allows for revascularization of nearly all intracranial arteries.

Conclusions:

• Saphenous vein bypass is a viable option for complex intracranial aneurysms requiring parent artery sacrifice.
• This technique provides a reconstructive solution when standard treatments are not feasible.
• The study reviews specific indications and management strategies for this advanced procedure.
