Background: Very large and giant aneurysms (≥20 mm) of the internal carotid artery (ICA) bifurcation (ICAbif) are definitely rare, and optimal treatment is not established. Endovascular treatments are reported as suboptimal due to difficulties of complete occlusion and tendencies to recanalization. Therefore, direct surgery remains an effective strategy if the clipping can be performed safely and reliably, although very difficult. Case Description: Two cases of ICAbif aneurysms (>20 mm) were treated. Prior assistant superficial temporal artery (STA)-middle cerebral artery (MCA) bypass was performed to avoid ischemic complications during prolonged temporary occlusion of the arteries in both cases. In Case 1 (22-mm aneurysm), the dome was inadvertently torn in applying the clip because trapping had resulted in insufficient decompression. Therefore, in Case 2 (28-mm aneurysm), almost complete trapping of the aneurysm and subsequent dome puncture was performed, and the aneurysm was totally deflated by suction from the incision. This complete aneurysm decompression allowed safe dissection and successful clipping. Conclusion: Trapping, deliberate aneurysm dome puncture, and suction decompression from the incision in conjunction with assistant STA-MCA bypass can achieve complete aneurysm deflation, and these techniques enable safe dissection of the aneurysm and direct clipping of the aneurysm neck. Direct clipping with this technique for very large and giant ICAbif aneurysms may be the optimal treatment choice with the acceptable outcome if endovascular treatment remains suboptimal.

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.

Thrombosed giant intracranial aneurysms usually present with symptoms and signs from their mass effect. Although multiple treatment options are available, direct clip reconstruction with thromboendarterectomy remains the gold standard. Here we present a 66-year-old man with seizure, aphasia and hemiparesis. Work-up revealed a giant partially thrombosed aneurysm of the internal carotid artery bifurcation with surrounding vasogenic edema. He underwent clip reconstruction of the aneurysm via a cranio-orbital approach. Although we prepared for bypass with the radial artery and/or the superficial temporal artery, we were able to clip-reconstruct the aneurysm without bypass. The patient improved upon his pre-morbid state after surgery and made an excellent recovery.The video can be found here: http://youtu.be/P_10hRQFuPo.

Surgical Embolectomy

Background: Dissection of the internal carotid artery (ICA) is an important cause of stroke. Intravenous alteplase administration and mechanical thrombectomy have been strongly recommended for selected patients with acute ischemic stroke. However, the efficacy and safety of these treatments for ischemic stroke due to ICA dissection remain unclear. Here, we report a case of acute ICA dissection successfully treated by microsurgical embolectomy. Case Description: A 40-year-old man presented with sudden left hemiparesis and in an unconscious state, with a National Institutes of Health Stroke Scale score of 14. Preoperative radiologic findings revealed an ICA dissection from the extracranial ICA to the intracranial ICA and occlusion at the superior-most aspect of the ICA. A dissection at the superior-most aspect of the ICA occlusion could not be confirmed; therefore, a surgical embolectomy with bypass was initiated. It became apparent that the superior ICA occlusion was not due to dissection but rather to an embolic occlusion; therefore, we undertook a surgical embolectomy and cervical ICA ligation with a double superficial temporal artery-middle cerebral artery bypass. The postoperative course was uneventful and, at the 6-month follow-up, the Modified Rankin Scale score for this patient was 1. Conclusion: Surgical embolectomy with or without bypass can safely treat acute ischemic stroke due to an ICA dissection that cannot be distinguished between a dissecting occlusion and an embolic occlusion. Thus, it may be considered as an alternative option for patients in whom mechanical thrombectomy has failed or for those who are ineligible for mechanical thrombectomy.
