Congenital anomalies of the cervical internal carotid artery (ICA) include anomalous origin, hypoplasia or aplasia, and anomalous branches. Among them, congenital anastomosis of the external carotid artery with the cervical ICA is extremely rare. We report herein two patients with congenital external-internal carotid artery anastomoses at the cervical segment with a remnant of the ICA stump or hypoplasia of the ICA.

Spontaneous bilateral cerebellar infarction in the territory of the superior cerebellar arteries is extremely rare. Occasionally there have been reports of bilateral cerebellar infarction due to vertebrobasilar atherosclerotic occlusion or stenosis, whereas no report of bilateral cerebellar infarction due to complicated hemodynamic changes. In this report, we present a patient with bilateral cerebral infarctions related to stenoses of bilateral internal carotid arteries, in whom vertebrobasilar system was supplied by multiple collaterals from both posterior communicating arteries and right external carotid artery. We performed stent-angioplasty of bilateral internal cerebral arterial stenosis, and then acute infarction developed on bilateral superior cerebellar artery territories. The authors assumed that the infarction occurred due to hemodynamic change between internal carotid artery and external carotid artery after stent-angioplasty for stenosis of right internal carotid artery.

6.Cerebral Oxygen Saturation Monitoring during Carotid Endarterectomy: A case report.
Korean Journal of Anesthesiology 1996;31(3):399-404
Cerebral oximetry based on the principle of near infrared spectroscopy is a relatively new technique that can monitor changes in cerebral oxygenation. Limited clinical experience with this monitoring technique exists, and the critical level of cerebral oxygen saturation below which neuronal damage takes place, has not been established. However, cerebral oximetry enables noninvasive and continuous cerebral oxygen saturation monitoring. It provides valuable information during carotid endarterectomy and other neurologic conditons. We experienced cerebral oxygen saturation changes during carotid endarterectomy. We monitored electroencephalography (EEG) simultaneously. During clamping of common carotid artery, there was a decrease in cerebral oxygen saturation from 65% to 58% without EEG changes. During clamping of external carotid artery, there was a decrease in cerebral oxygen saturation from 65% to 60% without EEG change.

A 38-year old man was admitted to our hospital due to a 5x6 cm sized pulsating mass in the right neck. He suffered from intermittent neck pain and hoarseness for two months due to the rapidly growing mass. The radiological examinations revealed an aneurysm of the right common carotid artery near the bifurcation, and it was compressing the internal and external carotid arteries. Endarterectomy of the right internal carotid artery, aneurysmectomy of the right common carotid artery and graft interposition were done, while the cerebral circulation was maintained by an internal shunt. Intraoperative injury to the nerve tissue around the aneurysm was avoided. He was discharged on the postoperative 7th day without any complications.

PURPOSE: To evaluate the blood flow patterns and the velocities of the carotid arteries in healthy Korean adults. MATERIALS AND METHODS: We evaluated the blood flow patterns and measured the peak systolic and end-diastolic velocities of the common, internal and external carotid arteries in 48 healthy adults who did not have cardiovascular disorders and neck lesions. The velocity difference was analyzed according to different age groups. In addition, peak systolic and end-diastolic velocity ratio of the internal to common carotid artery was estimated, and our data were compared with values reported by other authors. RESULTS: Generally, the velocity in the younger age group tends be to higher than in older group. The peak systolic and end diastolic velocities of the internal carotid artery were 84.5cm/sec and 30.5cm/sec. The peak systolic and end diastolic velocity ratio of the internal to common carotid artery were 0.715 and 0.966. The internal carotid artery was less resistant in blood flow than the external carotid artery. Our data were lower than the values which were reported by Bluth et al. CONCLUSION: The blood flow velocities of the internal carotid artery in healthy adults were lower than those of previously reported foreign values, but the patterns were similar.

Preoperative embolization of hypervascualr brain tumors is known to be an effective method to reduce intraoperative bleeding and to reduce the operative difficulty. The most commonly tumor vessels are branches of the external carotid artery, which are frequently embolized as a preoperative procedure. However, branches from the internal carotid artery, such as the ophthalmic artery, tentorial artery, or cortical branches sometimes feed tumors, but there are some limitations of embolization of branches from the internal carotid artery. In addition, hypervascular tumors are rarely associated with neoplastic aneurysms. Their possible role in producing massive intraoperative hemorrhage has been well recognized. We describe the successful embolization of the tumor vessels from branches of the internal carotid artery and their neovascularization.

BACKGROUND: The present study was aimed at defining the topological characteristics of the carotid intima-media thickness (IMT) in hypertensives, and to delineate whether the characteristics were different from those of non-hypertensive vascular risk factors. METHODS: B-mode carotid ultrasonography was performed in 33 participants who were devoid of stroke, ischemic heart disease, and carotid plaques. Longitudinal carotid images were obtained at 6 angular sites, 0 degree indexed adjacent to the external carotid artery (ECA) side from axial image crossing both internal carotid artery (ICA) and ECA, and then 45 degrees, 90 degrees, 180 degrees, 225 degrees, and 270 degrees. From the level of the flow divider, with an interval of 5 mm, up to 15 mm proximally, all the carotid IMT was measured. The IMT was then analyzed according to the levels and angles and compared according to either of hypertension or non-hypertension vascular risk factors. RESULTS: The carotid IMT showed asymmetric distributions in both the hypertension and non-hypertension risk groups. The IMT difference according to hypertension was observed better in the right carotid artery than the left. The right carotid IMT in the hypertension group showed significantly higher values at the most levels, and especially at 0 degree and 180 degrees of angular sites. CONCLUSIONS: It is important to understand the different topological characteristics of the carotid IMT according to the presence of hypertension, for a better reproducibility and predictability of the ultrasonic carotid IMT measurement.
