✓ A 44-year-old man experienced the sudden onset of horizontal diplopia and hemifacial numbness. Arteriography demonstrated a left intrapetrous carotid artery aneurysm. The patient was successfully treated with a left superficial temporal artery to middle cerebral artery bypass followed by balloon entrapment of the aneurysm. There have been at least 40 previously reported cases of aneurysms of the petrous portion of the carotid artery. These aneurysms can be mycotic, traumatic, or developmental in origin. They can present with massive otorrhagia or epistaxis from acute rupture or with decreased hearing and paresis of the fifth through eighth cranial nerves and, less frequently, of the ninth, 10th, and 12th cranial nerves caused by direct pressure. They can also produce pulsatile tinnitus, and sometimes they are discovered as a retrotympanic vascular mass during otological examination. The treatment of choice is carotid artery occlusion. Trapping of the aneurysm by detachable balloons eliminates immediately the risk of hemorrhage, offers the possibility of test occlusion of the internal carotid artery with the patient awake prior to permanent occlusion, and should also reduce the risk of thromboembolism. It should be preceded by a bypass procedure when preliminary evaluation indicates that the patient will not tolerate internal carotid artery occlusion.

✓ The authors report the case of a patient with transient ischemic attacks who was evaluated by duplex scanning, which demonstrated total carotid artery occlusion. Arteriography revealed what appeared to be a classic “string sign” in the cervical carotid artery, and a standard endarterectomy was planned. At surgery the internal carotid artery was found to be congenitally atretic, accounting for the string appearance of the arteriogram. The etiology, associated anomalies, differential diagnosis, and diagnostic evaluation of such lesions are discussed.

✓ A patient with known internal carotid artery occlusion developed transient ischemic attacks in the distribution of the occluded vessel. Arteriography demonstrated a thrombus clearly originating from the internal carotid artery stump, which was unassociated with significantly stenotic atherosclerotic disease of the ipsilateral common or external carotid arteries. Stump angioplasty and endarterectomy led to complete and sustained cessation of further symptoms.

Spontaneous Dissection

✓ Spontaneous dissection of the internal carotid arteries, including those dissections resulting in total occlusion, may be a spontaneously reversible process. A patient who had angiographic evidence of bilateral complete internal carotid artery occlusions of different ages of onset illustrates this process. This case suggests certain considerations regarding the pathogenesis of these dissections.

✓ The authors describe the use of a microanastomotic device to perform intracranial end-to-end vascular anastomoses. Direct end-to-end anastomosis was performed between the superficial temporal artery and branches of the middle cerebral artery (MCA) in three patients. Two patients had moyamoya disease, with severe proximal MCA disease, and one suffered an internal carotid artery occlusion with poor collateral flow. All patients reported a history of recent ischemic symptoms. Each anastomosis was accomplished in less than 15 minutes with technically satisfactory results. Postoperative angiographic studies demonstrated patency of the bypasses in all patients.

Cerebrovascular Complications

Abstract Objective: For patients with internal carotid artery occlusion with advanced narrowing of the ipsilateral external carotid artery (ECA), we performed preventive carotid endarterectomy (CEA) for the ECA stenosis before superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis for internal carotid artery occlusion. Methods: Between August 2002 and July 2005, we treated seven patients with such lesions, six men and one woman, ranging in age from 52 to 66 years (median, 60 yr). Before STA-MCA anastomosis, we performed preventive CEA for advanced ECA stenosis (>70%) to ensure sufficient blood flow to the STA. STA-MCA double anastomoses were performed more than 1 month after the CEA. Postoperative cerebrovascular complications and carotid restenosis were investigated. Results: All patients in the present series had an excellent postoperative course without cerebrovascular complications during either the CEA or STA-MCA anastomosis phase. Furthermore, no postoperative carotid restenosis occurred, and all STA-MCA anastomoses were patent during a mean follow-up period of 35.6 months. Conclusion: The present study suggests that surgical management by external CEA followed by STA-MCA anastomosis is safe and effective for patients with internal carotid artery occlusion and advanced stenosis of the ipsilateral ECA.

✓ The authors report a case of pituitary apoplexy occurring several hours after carotid angiography. The event was associated with stupor, focal headache, and left hemiparesis. Repeat angiography demonstrated intracranial occlusion of the right internal carotid artery. At surgery, a hemorrhagic pituitary adenoma was found to be compressing the internal carotid artery, and the removal of the tumor resulted in restoration of flow. The mechanism, presenting symptoms and signs, and treatment of pituitary apoplexy causing compression of a major vessel are discussed.

The Impact

The impact of ADAPT—“a direct aspiration first pass technique”—on intracranial vasculature is not well understood, since the change of arterial diameter is often not visible during aspiration. We present a unique case in which the impact of aspiration on the parent vessel was visualized due to a previously deployed Neuroform Atlas stent and a Pipeline embolization device. The patient presented with right internal carotid artery occlusion. An aspiration catheter was advanced over the microcatheter system and corked into the clot, located within the stents in proximal M1. The stents were seen to collapse both during electronic pump and hand aspiration with no evidence of stent migration. This demonstrates that it is crucial to engage the clot interface with the tip of the aspiration catheter while performing ADAPT. Placing the aspiration catheter remote from the clot may result in collapse of the artery proximal to the clot with subsequent ADAPT failure.(video 1)video 1.

✓ The authors report the occurrence of ipsilateral transient cavernous sinus syndrome during balloon test occlusion (BTO) of the cervical internal carotid artery (ICA) and discuss the involved pathomechanisms. The authors reviewed their series of 129 BTOs of the ICA performed between 1989 and 1996. Two patients developed facial paresthesias and transient palsies of the third through sixth cranial nerves during test occlusion of the cervical ICA. The tests were performed prior to planned permanent carotid artery occlusion for the treatment of a neck sarcoma in one patient and a giant cavernous carotid artery aneurysm in the other. The patients' symptoms resolved with deflation of the balloon. When the balloon was subsequently inflated above the inferior cavernous sinus artery (ICSA), one of the patients complained of mild facial discomfort. There was no contralateral weakness or mental status change during test occlusion in either patient. Angiography demonstrated good filling of the ipsilateral intracranial circulation via collateral vessels of the circle of Willis. In these two cases, the cranial nerves in the cavernous sinus were likely supplied by the ICA via the meningohypophyseal trunk and the ICSA. In each case, there was excellent blood supply to the ipsilateral cerebral hemisphere; however, there was probably inadequate retrograde filling of the cranial nerve collateral vessels located where the meningohypophyseal trunk and ICSA originated. These cases emphasize the importance of a patent external carotid artery—ICA connection for successful cervical carotid artery occlusion. Neurological examination during BTO was critical to interpret the clinical manifestations caused by the hemodynamic changes.
