✓ Twenty-four different kinds of fenestrated clips are introduced for the obliteration of unusual aneurysms. The clips were used for eight aneurysms of the internal carotid artery and 10 aneurysms of the vertebral artery. All but one of the aneurysms were successfully obliterated. Recommendations are made concerning the actual use of the clips.

✓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.

✓ Experience with surgical clipping of 16 large and nine giant aneurysms of the intradural internal carotid artery (ICA) is described. Reconstruction of the parent artery with part of the aneurysmal wall was necessary in the majority of cases. Multiple clips were required for satisfactory clipping in 20 cases. Complications related to the clipping procedure comprised occlusion and stenosis of the parent carotid artery in isolated cases. Straightening of the parent carotid artery with consequent kinking of the middle cerebral artery was seen in three cases of an aneurysm with a dome directed ventrally in the proximal segment of the ICA. The factors that caused straightening of the ICA are analyzed. It was observed that an excessive change in the direction of the ICA can cause cerebral infarction.

✓ The authors describe their experiences with five patients with delayed transient ischemic symptoms homolateral to internal carotid artery (ICA) occlusions. In each instance, initial arteriograms were interpreted as showing irreversible occlusions of these arteries in the neck and microvascular bypass procedures were contemplated. However, after repeat arteriographic evaluations with a modified injection technique, certain angiographic features were identified that suggested the mechanism of the symptoms in these patients and that their ICA's could be reconstituted in the neck. This was successfully accomplished in each patient with complete relief of ischemic symptoms. The angiographic technique employed and the arterial flow patterns identified in these patients are discussed. The details of the operative technique are described. It is concluded that routine arteriographic techniques may be inadequate to identify the reversible carotid occlusion. This may account for some of the confusion which surrounds the surgery of these vessels as well as the failure of extracranial-intracranial bypass to relieve recurrent ischemic symptoms in these individuals.
