BACKGROUND Trifurcation of the common carotid artery is an unusual variation. CASE REPORT We report a case of left common carotid artery trifurcation in a 74-year-old man. The left common carotid artery divided into the internal carotid, external carotid and facial arteries. Herein, the anatomy of the carotid arteries and the Doppler sonography and CT angiography findings of the left common c...

BACKGROUND Open injuries to the face involving the external carotid artery are uncommon. These injuries are normally associated with laceration of the facial nerve because this nerve is more superficial than the external carotid artery. Hence, external carotid artery lesions are usually associated with facial nerve dysfunction. We present an unusual case report in which the patient had an injur...

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 ce...

Anatomical variations of the carotid arterial system have a great impact on surgical approaches to the neck and radiological imaging interpretation. Although reports on internal carotid artery dolichoarteriopathy (kinking, tortuosity, coiling) have been reported, no report on dolichoarteriopathy of the external carotid artery has been described. Herein, we report a case with concurrent bilatera...

The Effects of Intra-Arterial Histamine on Blood Flow in the Internal and External Carotid Artery of Man • Both internal and external carotid artery phasic blood flow and arterial pressure were measured in five patients during a control period and after the intra-arterial injection of 13.8 fig of histamine phosphate into each vessel. In the internal carotid artery, flow for the group increased ...

The common carotid artery usually bifurcates into the internal and external carotid arteries at the level of C3-C4. Injury to common carotid artery during neck dissection is encountered rarly. Knowing the anatomical variation of common carotid like low lying bifurcation would prevent inadvertent injury especially by budding head-neck surgeons. We report a case of 46-yearold male undergoing surg...

Artery Arising from the Internal Carotid Artery I read with interest the article by Chan et al. They stated that there was a rare congenital anastomosis between the vertebral artery (VA) and internal carotid artery (ICA) with an absence of communication between the common carotid and cervical ICA. I, however, diagnose that there was an acquired occlusion of the ICA at its origin with a developm...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...
