Congenital absence of the common carotid artery is a rare vascular anomaly that is usually discovered incidentally in otherwise asymptomatic patients and can potentially pose significant diagnostic and therapeutic challenges. Although it has been typically associated with separate origins of the internal and external carotid arteries, a common origin of both arteries is exceedingly rare and has been reported in 6 cases to date. We present the case of a 70-year-old female, who was referred for a carotid ultrasound after a carotid bruit was auscultated. Carotid duplex scan identified the congenital absence of the right common carotid artery with no significant internal carotid stenosis. This was confirmed by a computed tomography angiography scan of the neck, which showed the right internal and external carotid arteries sharing a common origin off the distal brachiocephalic artery.

In an attempt to describe the morphofunctional consequences of uni- and bilateral aplasia of the common carotid artery (CCA), which is usually a vascular source of the external carotid (ECA) and internal carotid (ICA) arteries, we investigated online databases of anatomical and clinical papers published from the 18th century to the present day. We found 87 recorded cases of uni- and bilateral CCA aplasia in subjects from the first hours to the eighth decade of life, which had been discovered in 14 (known) countries. Four crucial parameters were described: the embryology of the carotid arteries, morphophysiology of the carotid arteries, CCA aplasia, and unilateral versus bilateral CCA aplasia, including history, general data, diagnosing, vascular sources, caliber, course of the separated ECA and ICA, associated vascular variants, and pathological disorders. To complete the knowledge of the morphofunctional consequences of the absence of some artery of the carotid system, and risking the possibility of repeating some words, as “carotid artery”, or “carotid aplasia” and the headings from our previous article about bilateral ICA absence, this review is the first in the literature that recorded all cases of the CCA aplasia published and/or cited for the past 233 years. Main characteristic of the CCA absence is its association with 21 different diseases, among which the aneurysms were in 13.69% of cases, and 17.80% of cases were without pathology.

Background: Arterial myointimal hyperplasia (MIH) has a significant impact on the long-term outcomes of vascular procedures such as bypass surgery and angioplasty. In this study, we describe a new and innovative technique to induce MIH using a dental flossing cachet in Wistar rats. Methods: The intimal damage in the common carotid artery was induced by inserting the tip of the dental flossing cachet through the external carotid artery into the common carotid artery and turning it on for 3 rounds of 20 s each (n = 10). After 2 weeks, the rats were anesthetized and the common carotid arteries of the experimental side and the contralateral side (control) were harvested and preserved for histopathological studies. Results: The experimental carotid arteries showed significant intimal proliferation and thickening compared to the controls. The intima/media ratio of the experimental and normal (control) common carotid arteries were 1.274 ± 0.162 and 0.089 ± 0.023 (mean ± SEM), respectively (p < 0.001). Conclusion: This technique is simple, inexpensive, and highly reproducible and it induces sufficient MIH to study this phenomenon in animal models.

AbstractPseudoaneurysms of the extracranial carotid arteries are rarely seen following irradiation for cancers of the head and neck. We present a patient with a pseudoaneurysm of the common carotid artery following a radical neck dissection and irradiation for thyroid carcinoma 20 years earlier. Following oesophagoscopical examination, a pseudoaneurysm of the right common carotid artery ruptured into the piriform sinus. The common carotid artery was embolized with multiple coils and the bleeding was halted. The relationship between the carotid artery aneurysm and irradiation, and the treatment of carotid artery aneurysm, is discussed.

This study assessed the hemodynamics of a patient-specific multiple stenosed common carotid artery including its bifurcation into internal and external carotid arteries; ICA and ECA, respectively. A three-dimensional computational model of the common carotid artery was reconstructed using a process of segmentation. Computational fluid dynamics was applied with the assumption that blood is Newtonian and incompressible under pulsatile conditions through the stenotic artery and subsequent bifurcation. Blood was modelled as ‘normal’ and ‘hyperglycaemic’. A region of large recirculation was found to form at bifurcation. The asymmetric velocity flow profile through the ICA was evident through the cardiac cycle with higher velocity at the inner walls of ICA. Hyperglycaemia was found to increase wall shear stresses on the carotid artery and reduce the blood velocity by as much as 4 times in ECA. In conclusion, hemodynamics in ICA and ECA are not equally affected by stenosis, with hyperglycaemic blood potentially providing additional complications to the clinical case.

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”

Introduction. The measurement of intima-media thickness (IMT) of carotid arteries has emerged as the method of choice for determining the anatomic extent of atherosclerosis and assessing cardiovascular progression. Statins are used in the primary and secondary prevention of cardiovascular and cerebrovascular disorders so as to reduce morbidity and mortality. Objective. To evaluate the effects of treatment with simvastatin in patients with elevated cholesterol levels and increased values of carotid arteries IMT. Methods. The study of 275 patients (155 male and 115 female, aged 37-79 years, mean 60.86 years) was performed from January 2008 - January 2010 at the Vascular and Endovascular Surgery Clinic of the Clinical Centre of Serbia. All patients were treated with simvastatin administered once a day for 6 months. Results. Simvastatin treatment resulted in a statistically signuficant decrease of the IMT thickness of the right common carotid artery. There was no statistically significant reduction in the IMT of the left common carotid artery as well as in the IMT of the right and left internal carotid arteries. Conclusion. Long-term simvastatin treatment results in the regression or slowing down atherosclerosis in symptomatic, as well as in asymptomatic patients with a lower grade of carotid stenosis (IMT below 2.5 mm).

AbstractThe aim was to determine the variations in the level of origin of carotid bifurcation and diameters of the common, internal, and external carotid arteries which is clinically important for several interventional procedures. Therefore, 165 human embalmed corpses were dissected. The data collected were analyzed using the Chi square-test and the Pearson correlation test. The results of previous studies have been reviewed. In relation to the level of the carotid bifurcation, taking as a reference point the hyoid bone, the values ranged from 4 cm below the hyoid body to 2.5 cm above the body of the hyoid, being the average height—0.33 cm, with a standard deviation of 1.19 cm. The right carotid bifurcation was established at a higher level (x = − 0.19 cm.) than the left one (x = − 0.48 cm.) (p = 0.046). On the contrary, no significant gender differences could be observed. The arterial calibres of the common and internal carotid arteries were higher in male than female. In the internal carotid artery (X = 0.76 cm.), the left was greater than the right (X = 0.72 cm.) (P = 0.047). However, no differences in the distribution of the calibre of the external carotid artery were found neither by side nor gender. Variations in the level of bifurcation and calibres of carotid arteries are relevant for interventional radiology procedures and head and neck surgeries. Knowledge of these anatomical references might help clinicians in the interpretation of the carotid system.
