✓ The authors describe a case of subarachnoid hemorrhage secondary to moyamoya disease in an adult Negro. To the authors' knowledge, this is the first such case reported. Moyamoya, the Japanese word for “puff of smoke,” describes the characteristic angiographic appearance of the collateral arterial network associated with internal carotid artery occlusion. The cause is unknown. Treatment consists of supportive care; the prognosis is variable.

✓ Two cases of internal carotid artery occlusion secondary to spontaneous dissection are reported. Both patients presented with transient ischemic attacks. Both had antiplatelet aggregation therapy, followed by spontaneous resolution of the occlusion. The period of healing seems to be relatively short. In both cases, restoration of flow was angiographically documented 14 days and 10 weeks after the initial arteriogram. Strategies for treatment of such patients are discussed.

✓ 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.

✓ The authors report a case of pituitary apoplexy resulting in bilateral internal carotid artery occlusion, with marked depression of consciousness and hemiplegia. After transsphenoidal tumor decompression, restoration of flow in both carotid arteries was documented angiographically and the patient made an excellent clinical recovery. The unique aspect of this case is that the pituitary apoplexy was apparently precipitated by neuroendocrine manipulation, performed as a preoperative test of pituitary function.

✓ 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 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.

✓ 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.

✓ It has recently been reported that pretreatment with a single dose of dexamethasone (0.1 mg/kg) 24 hours before hypoxia in 7-day-old rat pups is protective against an hypoxic-ischemic insult (unilateral carotid artery occlusion followed by 3 hours of hypoxia in 8% O2). The authors now examine whether pretreatment 6 hours before insult is equally effective and compare other agents potentially suitable for prophylaxis in neonatal hypoxia-ischemia, including the calcium antagonists flunarizine (30 mg/kg pretreatment), nimodipine (0.5 mg/kg pretreatment), and the 21-aminosteroid U-74389F (10 mg/kg pre- and posttreatment). For each active agent, there was also a vehicle-treated control group. Comparison of the mean area of ipsilateral infarction on brain coronal sections showed that there was no statistically significant difference between the various control groups (mean area of infarction 66% ± 4%). Pretreatment with dexamethasone 6 hours prior to hypoxia offered complete protection with no infarction. A beneficial effect was seen following pretreatment with flunarizine (mean area of infarction 33.6% ± 7.8%), although this degree of damage was still significantly different from that seen with dexamethasone pretreatment. Pretreatment with nimodipine or U-74389F offered no protection (mean area of infarction 77.5% ± 4% and 59% ± 10%, respectively). Unlike findings in adult animals and clinical studies, the current studies show that dexamethasone may have a role in the treatment of neonatal hypoxia-ischemia and deserves reappraisal.

✓ Ocular pneumoplethysmography (OPG), a semiautomated form of suction ophthalmodynamometry, was used to evaluate and follow 15 patients who underwent carotid endarterectomy and two patients in whom gradual carotid artery occlusion was performed for inoperable intracranial aneurysm. Postoperative corrected ophthalmic arterial pressures (COAP's) on the operated side in the carotid endarterectomy patients averaged 12.5 mm Hg higher than before surgery, the standard deviation being 4.9 mm Hg for clinically stable patients. There was no significant change in COAP on the contralateral side. Several problems were encountered in closing down carotid clamps, the most potentially serious being a precipitous fall in COAP with the final adjustment. The current uses of OPG and similar techniques are reviewed, and potential neurosurgical applications are discussed.
