✓ 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.

✓ The sources of blood supply of calvarial hemangiomas are not well established angiographically but have been reported to derive from the middle meningeal artery. A case is presented in which both the external and the internal carotid arteries supplied the hemangioma. The protean arteriographic picture is explained in terms of the various tissues the tumor involves (galea, calvarium, or meninges).

✓ Four cases are presented in which intermittent ischemic symptomatology was referable to a cerebral hemisphere. Arteriography in each case showed complete occlusion of the ipsilateral internal carotid artery in the neck with collateral filling of the ipsilateral intracranial carotid artery into the cavernous portion. Endarterectomy was performed successfully in each case from 1 to 5 weeks after the demonstrated complete occlusion. The collateral circulation to the intracranial portion of the internal carotid artery and the probable reasons for the technical success of these operations 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.

✓ The authors report a case in which the cause of a “spontaneous” carotid-cavernous fistula could not be demonstrated by selective angiography of external and internal carotid arteries. However, postmortem study of the cavernous sinuses revealed an unsuspected ruptured aneurysm of the internal carotid artery at the origin of the meningohypophyseal branch.

✓ Embolism from an aneurysm is one of the mechanisms involved in the pathogenesis of ischemic symptoms associated with intracranial aneurysms. Four cases are reported in which aneurysms of the internal carotid arteries and middle cerebral arteries were the source of emboli resulting in cerebral infarction. In the treatment of these aneurysms, it is best to clip the neck of the aneurysm with great care to avoid embolism due to extrusion of clot into the distal artery.

AbstractObjective:This study aimed to determine whether magnetic resonance imaging has a role in the evaluation of the sphenoid sinus and internal carotid artery. In addition, we aimed to establish reference measurements for the minimal distance between the internal carotid arteries.Method:The sphenoid sinuses and neighbouring internal carotid arteries of 90 patients were evaluated using sagittal T1-weighted and axial and coronal T2-weighted magnetic resonance images.Results:Sphenoid sinus pneumatisation was categorised as occipitosphenoidal (0 per cent), conchal (3.3 per cent), presellar (14.4 per cent) or sellar (82.2 per cent). The internal carotid artery protruded into the sphenoid sinus in 32.8 per cent, with a septum in 9.4 per cent. The incidence of sellar-type sphenoid sinus pneumatisation was higher in patients with protrusion of the internal carotid artery into the sphenoid sinus (p < 0.001). The incidence of presellar pneumatisation was higher in patients without internal carotid artery protrusion (p < 0.001). The minimal distance between the internal carotid arteries varied between 9.04 and 24.26 mm (mean, 15.94 mm).Conclusion:Magnetic resonance imaging can provide useful information about the sphenoid sinus and internal carotid artery, prior to endoscopic sphenoidotomy and trans-sphenoidal hypophysectomy.

✓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.

Autopsy showed a mycotic aneurysm of fungal origin at the junction of the right posterior cerebral and internal carotid arteries. Four of five reported cases of fungal aneurysm were due to Aspergillus infection.
