✓ The case of a 64-year-old woman with multiple intracranial aneurysms and abnormal ophthalmic arteries arising from the bifurcation of the internal carotid artery is described. It is believed that this type of anomaly of the ophthalmic artery has not previously been reported. The neuroradiological and operative findings of this case are presented.

Fine Print

✓ The author reports on 41 aneurysms of the proximal internal carotid artery (PICA) demonstrated in 36 patients with subarachnoid hemorrhage. The patients included a striking preponderance of women, and there was a high incidence of multiple aneurysms. In cases with multiple aneurysms the PICA aneurysm was usually found incidentally, a more distal aneurysm on the internal carotid artery being the source of hemorrhage. An infundibulum at the origin of a posterior communicating artery was unusually common in these patients. The origin of the ophthalmic artery is proposed as the angiographic landmark of the level at which the internal carotid artery penetrates the dura mater.

Doppler Flowmeter

✓ The authors report two cases in which the ophthalmic artery (OA) originated from the interdural portion of the internal carotid artery at the carotid dural ring and coursed within the dura. This configuration was observed during surgeries performed in 82 cases of juxta—dural ring aneurysms.In surgery for such an aneurysm, if the OA is not seen intradurally, an attempt should be made to find this kind of variation by using a Doppler flowmeter before sectioning the dural ring.

Anomalous Branch

✓ Angiographic and operative investigations revealed an anomalous branch of the internal carotid artery (ICA) in a patient with an anterior communicating artery (ACoA) aneurysm. The anomalous vessel originated from the right ICA at the level of the ophthalmic artery, and pursued an infraoptic and prechiasmatic path to supply both pericallosal arteries. The clinical features and possible genesis of this anomaly are discussed. This irregularity is frequently associated with intracranial aneurysms, especially those of the ACoA, and with other anomalies.

✓The authors report and discuss two cases in which collateral circulation could be angiographically demonstrated passing through the anterior spinal artery. Case 1 proved to have occlusions of the left internal carotid artery and both vertebral arteries. The basilar artery was visualized via the anterior spinal, the primitive trigeminal, and primitive otic arteries. The presence of multiple vascular malformations and an abnormal anterior spinal artery suggested that the latter had been functioning as collateral circulation since an embryonic stage. In Case 2, both internal carotids and both vertebral arteries were occluded by arteriosclerotic changes. It was assumed that the deleted anterior spinal artery visualized angiographically had developed into a collateral circulation with increasing age.

✓ Domestic violence leading to strangulation by an abusive spouse can cause carotid artery dissection. This phenomenon is rare and has been described in only three previous instances. The authors present their management strategies in three additional cases.Three young women aged 24 to 43 years were victims of manual strangulation committed by their spouses 3 months to 1 year before presentation. Two of the patients suffered delayed cerebral infarctions before presentation and angiography demonstrated focal, mirror-image severe residual stenoses in the high-cervical internal carotid artery (ICA), which were characteristic of a healed chronic dissection; there was no evidence of fibromuscular dysplasia. One of these patients underwent unilateral percutaneous angioplasty with stent placement, and the other underwent bilateral percutaneous angioplasty. Both patients have recovered from their strokes and remain clinically stable at 8 and 20 months posttreatment, respectively. The third patient presented with bilateral ischemic frontal watershed infarctions resulting from an occluded left ICA and a severely narrowed right ICA. Given the extent of the established infarctions, this case was managed with a long-term regimen of anticoagulation medications, and the patient remains neurologically impaired.These cases illustrate the susceptibility of the manually compressed ICA to traumatic injury as a result of domestic violence. They identify bilateral symmetrical ICA dissection as a consistent finding and the real danger of delayed stroke as a consequence of strangulation. Endovascular therapy in which percutaneous angioplasty and/or stent placement are used can be useful in treating residual focal stenoses to improve cerebral perfusion and to lower the risk of embolic or ischemic stroke.

✓ Five cases of a congenital berry aneurysm of the internal carotid artery with origin partially intradural and fundus mainly intracavernous are presented. Angiography does not allow a precise definition of the amount of aneurysm that is intradural, a fact of importance when planning treatment of these cases. However, the angiographic features are characteristic of the type and suggest that these aneurysms be grouped together as a separate entity.

✓ A new aneurysm clip has been developed specifically for internal carotid artery (ICA) aneurysms. This fenestrated clip's occluding blades deviate laterally, since the majority of ICA aneurysms protrude posterolateral to the parent artery. The clip was applied safely in seven recent patients with ICA aneurysms.
