Abstract Revascularization techniques for microsurgical manage-ment of middle cerebral artery (MCA) bifurcation aneurysms are often necessary for treatment of fusiform or giant aneurysms. Augmentation of the standard pterional approach to include an extended orbitozygomatic or modified orbitozygomatic approach provides a wider and more favorable approach to the MCA when attempting revascularization. Direct excision of a giant aneurysm (aneurysmectomy) with mobilization and reanastomosis of the MCA afterward has been reported. This patient had a giant MCA bifurcation aneurysm for which aneurysmectomy and distal reanastomosis were performed between the M1 and two M2 branches via a modified orbitozygomatic craniotomy. A second bypass between a third M2 branch at the ipsilateral superficial temporal artery was performed. Postoperative angiography confirmed patency of the bypasses. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.

✓ Giant intracranial aneurysms often pose difficult management issues. Such aneurysms may not be amenable to direct surgical attack because of their size, location, or lack of a clear aneurysmal neck. In such cases, a combination of strategies may provide a means of proximal aneurysm occlusion and distal cerebral revascularization. The authors report the successful treatment of a giant (186.8-ml) serpentine aneurysm of the left middle cerebral artery (MCA) in a 14-year-old boy. The aneurysm was managed in a two-stage procedure in which the MCA branches distal to the aneurysm were anastomosed first with branches of the left superficial temporal artery. After the bypass procedure, direct occlusion of the MCA was performed at the proximal base of the aneurysm at its site of dilatation. The patient had no intraoperative or postoperative complications and was intact neurologically 6 months following the procedures.

Abstract This report graphically illustrates the consequences of flow augmentation through extracranial-intracranial bypass grafts. Propagation of clot from a thrombosed middle cerebral artery aneurysm into the middle cerebral artery produced transient ischemic attacks. Superficial temporal artery-middle cerebral artery bypass was performed to augment cerebral blood flow. Postoperative angiography demonstrated filling of the aneurysm through improved collateral channels. The role of bypass operation in the presence of an aneurysm and its contribution to collateral blood flow and clot lysis are discussed.

Abstract Broad-based aneurysms of the middle cerebral artery M1 bifurcation usually involve aneurysmal inclusion of an M2 vessel wall within the neck. This necessitates a consideration of performing a bypass to preserve the patency of distal perfusion. The patient in this video is a 17-yr-old man who presented after experiencing a small stroke and was found to have a partially thrombosed giant middle cerebral artery M1 bifurcation aneurysm with an M2 branch arising from the aneurysm. To maintain the perfusion of the M2 brain, the anterior temporal artery was used to perform a side-to-side anastomosis with the M2 brain at risk. A distal clip was determined to be not necessary for aneurysm occlusion because the aneurysm was almost completely thrombosed before the operation and the bypass flow was anticipated to be sufficient to facilitate complete thrombosis. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.

Abstract We present the case of a 34-yr-old male who suffered repeated ischemic events resulting in right-sided weakness. He was found to have left M1 segment near occlusion on angiography with a large area of uncompensated hypoperfusion. The patient underwent a direct superficial temporal artery-middle cerebral artery (STA-MCA) bypass. Direct bypass in the acute setting of ischemia has been previously described.1-5 Moyamoya ischemic disease can be treated with either direct or indirect surgical revascularization. There have been several techniques developed for direct bypasses in moyamoya ischemic disease. These include the standard 1-donor 1-recipient (1D1R) end-to-side (ES) bypass, the “double-barrel” 2-donor 2-recipient (2D2R) ES bypass, and the more recently developed 1-donor 2-recipient (1D2R)6,7 utilizing both an ES and a side-to-side (SS) bypass with a 1-donor vessel. The case presentation, surgical anatomy, decision-making, operative nuances, and postoperative course and outcome are reviewed. The patient gave verbal consent for participating in the procedure and surgical video.

Abstract Cerebral revascularization is the treatment of choice for select complex intracranial aneurysms unamenable to traditional approaches.1 Complex middle cerebral artery (MCA) bifurcation aneurysms can include the origins of 1 or both M2 branches and may benefit from a revascularization strategy.2,3 A novel 3-vessel anastomosis technique combining side-to-side and end-to-side anastomoses, allowing for bihemispheric anterior cerebral artery revascularization, was recently reported.4  This 2-dimensional operative video presents the case of a 73-yr-old woman who presented as a Hunt-Hess grade 4 subarachnoid hemorrhage due to the rupture of a large right MCA bifurcation aneurysm. The aneurysm incorporated the origins of the frontal and temporal M2 branches and was deemed unfavorable for endovascular treatment. A strategy using a high-flow bypass from the external carotid artery to the MCA with a saphenous vein (SV) graft was planned to revascularize both M2 branches simultaneously, followed by clip-trapping of the aneurysm. Intraoperatively, the back walls of both M2 segments distal to the aneurysm were connected with a standard running suture, and the SV graft was then attached to the side-to-side construct in an end-to-side fashion. Catheter angiograms on postoperative days 1 and 6 demonstrated sustained patency of the anastomosis and good filling through the bypass. The patient's clinical course was complicated by vasospasm-related right MCA territory strokes, resulting in left-sided weakness, which significantly improved upon 3-mo follow-up with no new ischemia.  The patient consented for inclusion in a prospective Institutional Review Board (IRB)-approved database from which this IRB-approved retrospective report was created.

Abstract This case history of a man with bilateral carotid artery occlusions presents angiographic documentation of the embolization of a superficial temporal-middle cerebral artery bypass. The embolic source was thrombotic and/or atheromatous debris that had collected in the persistent stump of one of the occluded internal carotid arteries.
