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.

Flow Monitoring

Abstract We review our recent experience with occlusion of the cervical internal carotid artery (ICA) in 15 patients with symptomatic aneurysms of the cavernous segment. All the patients were women and ranged in age from 38 to 74 years. Ten patients sought treatment initially for ophthalmoplegia, 9 for retro-orbital pain, 8 for facial paresthesia, and 3 for loss of vision. Two patients had symptoms of transient ocular or brain ischemia. The diameter of the aneurysm was greater than 3 cm in 10 patients. Ten patients underwent gradual occlusion of the ICA by Selverstone clamp under anticoagulation and monitoring of neurological status. One patient underwent ligation of a severely stenotic ICA under general anesthesia and electroencephalographic monitoring. Four patients underwent trapping of the aneurysm (after attempts at direct obliteration) under electroencephalographic and cerebral blood flow monitoring. Two patients with incompetent circle of Willis collaterals underwent prophylactic superficial temporal artery to middle cerebral artery bypass surgery prior to ICA occlusion. There was no postoperative clinical change in 9 patients. Ophthalmoplegia improved in 2 patients, and facial pain improved in 3. Three patients developed new extraocular muscle palsies within hours of ICA occlusion; these resolved in all patients by 1 week postoperatively. No change in aneurysm size was documented by serial postoperative computed tomographic or magnetic resonance imaging scans. After a follow-up of 5 to 6 years (range, 6 months-9 years), 11 patients have remained neurologically stable. Two patients experienced delayed transient worsening of visual or facial symptoms. Two patients developed delayed ipsilateral brain ischemia: one patient had a visibly patent superficial temporal artery to middle cerebral artery bypass; the second patient had an occluded A-1 segment that previously had been patent. These results are discussed in light of direct approaches and recent techniques of intervention.

Thickened Intima

Background and Objective Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass is a procedure to reconstruct cerebral blood flow in the MCA territory. In some cases, the STA wall is thickened and the size discrepancy between STA and MCA is apparent. In such a situation, STA-MCA bypass is challenging. We present two patients who underwent STA-MCA bypass using STA in which a thickened intima was removed. We discuss the usefulness of this rescue technique. Patients and Results A patient with an atherosclerotic MCA occlusion and another with an occluded internal carotid artery are included. Endarterectomy of STA was performed before or during anastomosis, and the intima-resected STA was anastomosed to MCA. In both cases, the STA was thick and hard, and it was difficult to anastomose the STA as it was to the MCA. Patency of the bypass was confirmed by postoperative angiography. Conclusion Endarterectomy of a thickened STA might be an effective rescue technique in cases with severely atherosclerotic STA in STA-MCA bypass.

Abstract Objective: Aneurysm formation is a complication of superficial temporal arterymiddle cerebral artery bypass surgery occurring as pseudoaneurysms caused by technical failure, but also as true aneurysms discovered after long-term follow-up. Clinical Presentation: A 53-year-old woman presented with a left internal carotid artery cavernous aneurysm manifesting as double vision. Superficial temporal artery-middle cerebral artery bypass, internal trapping of the internal carotid artery, and embolization were performed. Three years later, angiography disclosed a distal middle cerebral artery aneurysm. A 70-year-old man who had undergone right superficial temporal artery-middle cerebral artery bypass after internal carotid artery occlusion died of subarachnoid hemorrhage from a ruptured anterior spinal artery aneurysm 21 years later. Angiography and postmortem examination revealed de novo aneurysm formation on a middle cerebral artery branch adjoining the anastomotic site. Both patients had hypertension and multiplicity of aneurysms. Interpretation: Both cases were de novo true aneurysms caused by hemodynamic stress because of saccular to fusiform shape, location extending to the middle cerebral artery, high perfusion pressure, projection along the hemodynamic stress, and presence of common risk factors. Conclusion: Bypass surgery is increasingly performed in patients with complicated aneurysms if sacrifice or temporary occlusion of any major vessel is required. Therefore, de novo aneurysm formation may not be rare in patients with risk factors such as hypertension or multiple aneurysms. Extended follow-up examination is required in such patients.
