The best treatment for intracranial aneurysms is undoubtedly neck-clipping; however, some aneurysms, such as giant aneurysms or those with a broad neck, cannot be treated in this manner. The microvascular suture technique introduced by Yasargil contributed to the wide indications for curative operations of some unclippable aneurysms.
The authors present two cases of such unclippable aneurysms, which could be treated by utilizing the microvascular suture technique. The first case, a giant middle cerebral artery aneurysm, was managed with excision and end-to-end anastomosis, and the second case, an irregular shaped broadnecked aneurysm of the internal carotid artery, was treated by combining internal carotid trapping with an extracranial-intracranial bypass using an interposed saphenous vein graft. The patients had no postoperative neurological deficit. Alternative treatment is also discussed in this paper.
