Supraclinoid Internal Carotid Artery

✓ The case of an aneurysm occurring at the site of fenestration of the supraclinoid portion of the left internal carotid artery (ICA) is reported. A 37-year-old woman presenting with subarachnoid hemorrhage was found to have bilateral ICA aneurysms at the level of the posterior communicating arteries (PCoA's). The patient underwent right-sided craniotomy with uneventful clipping of the right PCoA aneurysm, and attempted clip placement on the contralateral left ICA aneurysm. The follow-up angiogram revealed a residual dome on the left ICA aneurysm, which was noted to originate at the proximal end of a fenestration of the left supraclinoid ICA. This represents the third reported case of fenestration of the intracranial ICA associated with an aneurysm. Intracranial artery fenestrations and their embryological origins are also reviewed.

✓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.

✓ A 54-year-old woman was admitted with a complete occlusion of the right internal carotid artery and a 25% stenosis of the left internal carotid artery. Intracranial circulation on the right side was restored by taking a vein from the leg and anastomosing the vein of the intracranial carotid artery just distal to the anterior clinoid process. Prior to insertion the vein was turned inside out, the valves removed and then reinverted allowing the distal end of the vein to be anastomosed to the intracranial internal carotid artery. The blood flow was therefore reversed in the vein. The proximal end of the vein was anastomosed to the common carotid artery. Upon completion there was excellent circulation in the bypass graft and internal carotid artery.

Object. The aim of this study was to determine the prevalence of angiographically identifiable skull base arterial branches that potentially serve as collateral conduits during a balloon occlusion test (BOT) of the internal carotid artery (ICA). The authors posited that neurological deficits in patients who had previously tolerated the occlusion test may be attributable to an unrecognized collateral support through these channels (operant during proximal ICA BOT) when permanent ICA occlusion was performed more distally. Methods. In 481 cases (962 ICAs), cerebral angiograms obtained during routine Wada testing were retrospectively reviewed. Two hundred sixty-one patients had at least one angiographically identifiable ICA branch; 109 patients had two or more branches. A meningohypophyseal branch of the cavernous ICA was identified on the right side in 108 patients and on the left in 122. A vidian artery originated from the petrous portion of the ICA on the right side in 58 patients and on the left in 85. The inferolateral trunk revealed itself as a branch of the cavernous ICA on the right side in 17 patients and on the left in 33. A caroticotympanic artery arose from a left cavernous ICA. A persistent trigeminal artery was situated on the right side in two patients and on the left in three. More than half of the patients had angiographically identifiable and perhaps hemodynamically significant skull base branches of the ICA, and approximately one quarter had more than one identifiable branch. Conclusions. The authors recommend that patients be screened during angiography studies performed prior to BOT in branches of the proximal intracranial ICA and that the site of BOT be moved distally if such branches are identified.

✓ The authors describe an indwelling intraluminal shunt for use during graft bypass procedures of the cavernous internal carotid artery. The clinical use of this shunt in a patient with meningioma invading the right cavernous sinus is described. This shunt has also been found applicable during carotid endarterectomy, and should prove to be a useful addition to the neurosurgical armamentarium for skull-base surgery.
