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.

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.

One of the rare anomalies of the common carotid artery is the separate origin of the internal and external carotid artery. We present the case of a patient who was admitted to hospital for cerebral angiography to exclude an intracranial aneurysm. The DSA revealed a giant aneurysm of the right internal carotid artery and separate origins of external and internal carotid arteries from the aortic arch. To our best knowledge no similar case has previously been reported.

Abstract The morphological characteristics at the level of the bifurcation of the common carotid artery were studied on 46 cases, finding that the most frequent, in 52.17% of cases, the common carotid bifurcation appear as the letter “V”, with two possible variations: a wide “V”, in 43.48% of cases and narrow “V” in 8.7% of cases. In 30.43% of cases, the two carotids showed an ascending traject, united for 1-2 cm up to their crossing; in 13,04% of the cases the two arteries were superimposed, the external located anteriorly. In only in two cases on the right side (4.35% of cases and 8.33% of right samples) we found a peculiar aspect of a “U” shaped bifurcation. Regarding the caliber of the external carotid artery, we found that in 43.33% of the cases the external carotid artery had a similar diameter to the internal carotid, also in 43.33% of the external carotid artery have a higher caliber than internal one and the remaining 13.33% of the cases, the external carotid artery had a smaller diameter than the internal one, with all cases on the left (16.67% of left carotid arteries). The caliber of the right external carotid artery was between 4 to 5.6 mm and the one of the left was between 3.6 to 5 mm. When the external carotid was more voluminous than the internal, the differences were 0.5 to 1.2 mm and when the internal carotid was more voluminous than the external, the differences were smaller, 0.2 to 0.8 mm. In relation to the common carotid, the external carotid had a smaller caliber from 0.6 to 1.1 mm. Regarding the external carotid traject, most commonly, from the bifurcation of the common carotid, the external carotid artery showed a vertical trajectory, in 50% of cases; in 40% of cases, the traject was oblique superomedially and in 6.67% of cases the external carotid artery described a curve with the convexity facing laterally, with all cases on the right (11.76% of right carotid arteries); in 3.33% of cases, both on the left (7.69% of the left carotid arteries), the external carotid artery traject described an inverted italic “S”

Internal Carotid Arteries

The absence of an internal carotid artery is a rare congenital anomaly. In the absence of the internal carotid artery, collateral circulations develop through the circle of Willis, persistent embryonic arteries or transcranial collaterals of the external carotid artery. Six pathways of collateral circulation have been described. Intercavernous anastomosis is between cavernous segments of the bilateral internal carotid arteries and is rarely seen. Patients with an absence of the internal carotid artery can be completely asymptomatic. However, these patients can present with subarachnoid hemorrhage or stroke accompanying cerebral aneurysm or abnormal collateral. We combined our case with 33 previous publications to form a retrospective series including 35 cases of unilateral internal carotid artery agenesis with intercavernous anastomosis.

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.

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.

Internal Carotid Arteries

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.
