A minority of traumatic carotido-cavernous fistulas (CCF) are of the indirect variety, and then usually supplied only by meningeal branches of the ipsilateral external carotid artery (Type C). We describe a case of a Type D CCF due to traumatic injury of the inferolateral trunk (ILT), and describe its angiographic features and endovascular management through both the external and internal carotid arteries following a failed transvenous approach.

Background: The common carotid, internal and external carotid arteries and their branches serve as major source of blood supply in head-neck region of human and are often encountered during numerous surgical and clinical interventions of neck.Methods: We dissected and examined both sides of neck in 49 well embalmed cadavers (98 sides). We recorded the following anatomical parameters of carotid arterial system-level of bifurcation, the relation between internal and external carotid arteries, branching pattern of anterior branches of external carotid artery, tortuosity in carotid arterial system, and relation of hypoglossal nerve with the carotid arteries.Results: In 56.16 % cases, the common carotid arterial bifurcation took place at the upper border of thyroid cartilage though high bifurcation was quite common (43.88%). The external carotid artery was located antero-medial to internal carotid artery in most cases (93.87%). Abnormal tortuosity of carotid arterial system was detected in 2.04% cases only. In 86.73% cases, the hypoglossal nerve crossed the internal and external carotid artery superior to carotid bifurcation above the level of hyoid bone while in 1 case it crossed immediately inferior to carotid bifurcation. In branching pattern, following variations were observed- linguo-facial trunk in 15.3% cases, thyro-lingual trunk in 5.1% cases, origin of superior thyroid artery from common carotid in 10.02% cases and origin of superior thyroid from internal carotid in one case (1.02%).Conclusions: The carotid arterial system has complex and variable anatomy in neck and this information should be kept in mind to avoid unwanted damage during surgical procedures of neck.

AbstractThe arterial pattern of the human body is one of the systems that show a large number of variations. Many reports are available regarding variations of common carotid, external and internal carotid arteries and branches of external carotid artery. We describe a very rare case of lateral position of external carotid artery. The external carotid artery was lateral to the internal carotid artery at the bifurcation of the common carotid artery. The clinical importance of this variation is discussed.

Internal Carotid Arteries

The accuracy, and possible clinical application of non-invasive ultra sound imaging of the cervical carotid, artery in patients with cerebrovascular disease has been investigated by comparing a pulsed multi-channel directional Doppler imaging devise (“MAVIS” - GEC Medical) with conventional carotid angiography. Of 23 normal or minimally diseased internal carotid arteries only 4 appeared as stenosed on Doppler angiography, the other 19 were normal; of 14 stenosed arteries only 1 appeared normal on imaging,1 appeared occluded end 12 showed clear images of stenosis; all 6 occluded arteries appeared occluded on ultra sound imaging. It was difficult to obtain satisfactory images of the external carotid arteries in all cases. The additional facility to display a velocity flow profile at preselected points along the arterialimage should increase the usefulness of this technique, particularly when there is only minor atheromatous irregularity or ulceration, and such a device will be briefly disrussed.

Collateral networks between the external carotid artery and internal carotid arteries become crucial for cerebral perfusion after occlusion of internal carotid arteries. We report the first case of a patient who received percutaneous transluminal angioplasty and stenting in a collateral vessel between the external and internal carotid artery for treatment of radiation induced severe stenosis of the internal carotid artery in the context of a contralateral internal carotid artery occlusion.

Abstract Our experiences with a patient who developed recurrent hemispheric transient ischemic attacks 3 1/2 years after ipsilateral carotid endarterectomy are described. Although repeat arteriography demonstrated smooth and unobstructed common and internal carotid arteries and a normal intracranial circulation, there was complete occlusion of the external carotid artery at its origin, which appeared as a stump or diverticulum at the origin of the internal carotid artery. This stump was filled with atherothrombotic debris and served as a source of emboli to the adjacent and patent internal carotid artery. Excision of the stump effected complete relief of the recurrent ischemic symptoms. The pernicious potential of an external carotid obstruction when adjacent to a patent internal carotid artery should be recognized. To prevent this avoidable complication of carotid endarterectomy, we recommend that the origin of the external carotid artery be treated with the same standards of technical perfection as those customarily applied to the internal and common carotid arteries during this procedure.

Group 1

The study included 1172patients (410 men and 762 women) at the mean age of 60.3±10.4years with grade I-II (stage I-II) arterial hypertension (AH) admitted to the clinic of Institute of Experimental Medicine. The patients were divided into 2 groups based on the results of clinical and laboratory diagnostics. Group 1 (n=525) included patients with AH and hepatobiliary system (HBS) diseases, group 2 (n=647) patients with AH without HBS diseases. The patients group 1 had a thicker intima-media complex of carotid arteries, higher peak systolic bloodflow rate in the internal and vertebral carotid arteries, more pronounced coiling of internal carotid arteries than patients of group 2. Patients with AH and HBS diseases exhibited correlation between blood flow rate in external carotid arteries and atherogenicity coefficient. Duplex scanning of neck vessels of in patients with AH without HBS diseases revealed peculiar changes of the intima-media thickness and hemodynamically significant changes of the blood flow in the internal carotid arteries that may be of prognostic value in this nosological syntropy and require the personified approach to diagnostics, treatment, and prevention of these conditions.
