Surgical treatment for anterior spinal artery aneurysm

Aneurysms arising from anterior spinal arteries are very rare. Rupture of an anterior spinal aneurysm is a rare cause of subarachnoid hemorrhage accounting for less than 1% of all cases reported in the literature. The management options include a surgical approach, endovascular embolization, or conservative treatment. Endovascular treatment with embolization using coils or liquid embolic agents is very difficult to reach to the aneurysm and to preserve parent artery. So the surgical approach is usually employed in origin of anterior spinal artery aneurysm. Far lateral approach is useful method to approach to the origin of anterior spinal artery and manage the aneurysm.
