Öğe Anatomic course, Variations and Clinical Importance of the Median Nerve(Düzce Üniversitesi, 2013) Ulusoy, Mahinur; Acar, Musa; Zararsız, İsmailThe purpose of this review is to give information about anatomic course, variations and lesionsof the median nerve. Median nerve innervates the most of the forearm flexor muscle and themuscles of the tenar of the hand. Moreover, it is one of the most important peripheral sensorynerve branches that joins the sensory innervation of the hand. It is important to detect locationsthat median nerve exposed to trauma and the anatomic localizations that nerve is damageddue to entrapment neuropathies. As a result, knowledge of both anatomical course of mediannerve and its variations are very important for diagnosis and treatment of the peripheral nervediseases and surgical applicationsÖğe Variations of vertebral artery: Multidetector Computerized Tomographic Angiography Study(Düzce Üniversitesi, 2014) Ulusoy, Mahinur; Acar, Musa; Acar, Serpil; Sakarya, Mehmet Emin; Zararsız, İsmailObjective: The aims of this study are detecting Turkish Society’s vertebral artery variationsidentified on MDCT angiograpy and determining origin variations of vertebral arteries and theirarising level from subclavian artery.Materials and Methods: MDCT angiographic images of 96 patiens (31-86 years old, 64 maleand 32 female) were evaluated. Images were obtained using 64 slice multidedector CT scanimages of vertebral artery.Results: In this study, investigations of origin levels of vertebral arteries showed vertebral arterymostly originated from Th1-2 vertebrae in males and vertebral artery mostly originated fromTh1 vertebrae in females. In six different vertebral artery cases variations were detected. Amongthese variations, in four cases vertebral arteries originated from aortic arch (4.1%), in one casevertebral artery is originated from common carotic artery (1%). One patient’s (1%) left vertebralartery was absent, the right vertebral artery alone created basilar artery in the basis cranii.Conclusions: Knowledge of vertebral artery variations that were frequently detected in Turkishsociety is important in explaining the symptoms of vertebrobasiler insufficiency. Identificationof these variations will be very useful for neurology, neurosurgery and cardiovascular surgeryspecialists and radiologists
