A 42-year-old female patient, who had been diagnosed with an occlusion of her left internal carotid artery (ICA) following Doppler ultrasonographic (US) and digitally-subtracted angiographic (DSA) examinations performed in an outer healthcare center in order to eliminate the underlying cause of her complaint of amorosis fugax, later applied to our hospital with the same complaint. At Doppler US performed in our hospital’s radiology department, her right common carotid artery (CCA) was normal, but her left CCA was hypoplastic. The right internal artery (ICA) was validated as normal. At the left side, however, the ICA was apparent only as a stump and it did not demonstrate a continuity. The diagnosis of ICA agenesis was confirmed by the utilization of Doppler US, CT, and DSA imaging, and it was concluded also that ipsilateral CCA hypoplasia could be evaluated as an important clue to the diagnosis of ICA agenesis.

Background: Carotid artery dimensions are increasingly used for detecting early atherosclerosis and predicting clinical complications. Aim was to explore relationships between gender, age and body mass index (BMI) and the diameters of the common carotid artery (CCA) and internal carotid artery (ICA) using ultrasonography.Methods: This was a cross-sectional study carried out at the University of Maiduguri Teaching Hospital between February-October, 2011. The 400 adult males and females above 18 years underwent carotid artery ultrasonography for measurement of the IMT of the common and internal carotid arteries. The influence of age, sex, weight, height, and the basal metabolic index (BMI) was investigated.Results: There were 239 (59.80%) males and 161 (40.20%) females aged between 18 to 81 years (Mean±SD, 36.74±14.79 years). The mean±SD diameters for right common carotid artery (RCCA) and left common carotid artery (LCCA) were 6.39±0.71mm and 6.28±0.74mm respectively. The right internal carotid artery (RICA) and left internal carotid artery (LICA) had mean±SD diameters of 4.63±0.63 mm and 4.61±0.63 mm respectively. The luminal diameters of the carotid arteries increased significantly with age and increased BMI. The luminal diameters of the CCA and ICA were significantly smaller in women than in men.Conclusions: Common carotid and internal carotid artery luminal diameter tends to be larger in men than women among adults and increases with age and BMI. There is no difference in the luminal diameter between the left and right carotid artery.

✓ A case is reported with congenital absence of the left internal carotid artery associated with an aneurysm on the contralateral carotid syphon. Eight similar cases are reviewed in brief. The possibility of hemodynamic abnormality as the cause of the aneurysm is discussed.

Radiographic Appearance

AbstractMost arch anomalies are asymptomatic and detected incidentally on imaging or on autopsy. Occasionally, such anomalies can manifest clinically when associated with another vascular pathology such as an intracranial aneurysm. In this report, we describe a rare case of agenesis of the left common carotid artery with separate origin of the left internal carotid artery and the external carotid artery from the arch discovered on digital subtraction angiography performed during the evaluation of subarachnoid hemorrhage. Knowledge of such anomalies and radiographic appearance is essential for interventional neuroradiologist in planning treatment of such cases.

Inside Out

✓ 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.

Abstract The study of CT angiographies performed on a CT scanner GE LightSpeed VCT16 Slice CT revealed some morphological features of the ophthalmic artery related to origin, morphometry and the internal carotid arteries in the vicinity of this artery. The diameter of the left internal carotid artery under the origin of the ophthalmic artery was between 4.0-5.8 mm and that of the right ophthalmic artery at the same level was between 4.1-5.3 mm. Under the origin of the ophthalmic artery, the internal carotid arteries were larger in diameter on the leftside in 80% of cases, with differences of 0.1-0.3 mm, and on the right side these differences were between 0.1-0.2 mm, 20% of cases. The diameter of the left internal carotid artery above the origin of the ophthalmic artery was 3.7-5.0 mm, and the origin of the right carotid artery at the same level was 3.8-5.0 mm.
