Abstract
Introduction: The pool of the vertebrobasilar system is providing the blood supply of the brain. Abnormalities along the course of the extracranial part of the internal carotid arteries (ICA) may influence the blood supply of the brain. The elongation of the extracranial part of the ICA may occur as tortuosity, a circular shaped elongation or coiling, or an elongation with angulation less than 90 degrees (kink).Aim: The aim of our research is to present by an in-depth dissection a clinical case with spectacular abnormality along the course of the extracranial part of the ICA and the histological condition of the arterial wall.Methods: At routine anatomical dissections 7 fixed bodies have been researched. At one of them there have been found pathological features. The finding has been photographed and histological preparations have been made.Results: In this case there has been found bilateral abnormality along the course of the extracranial part of ICA: elongation of the left internal carotid and elongation with kinking of the right one. Steno-occlusive atherosclerotic lesions have been found on both of them in the area of the bifurcation. A concomitant kinking of the left vertebral artery (VA) has also been found.Conclusion: Depending on its type the abnormalities along the course of extracranial segment of the internal carotid artery (ICA) may have or not have a bad influence on the blood supply of the brain. Their connection with the ischemic apoplexy has not been clarified. The presence of bilateral elongation and the combination with atherosclerotic lesions as in the shown clinical case probably lead to hemodynamically significant pathology.
