Abstract

The superior cerebellar artery (SCA) is a vessel anterior to the brainstem, usually originating from the basilar artery (BA). In this case, a different course of left SCA in a 74-year-old male cadaver was reported. The origin of the SCA was found to be a unilateral double root at the left side on the anterior surface of the pons. The distances of the starting points of roots to the bifurcation of BA were 31.09 mm on the right side, on the left side the rostral root was 33.84 mm and the caudal root was 30.95 mm. The diameter of the right SCA was 2.37 mm, the left rostral root was 2.05 mm and the caudal root was 1.24 mm. Knowing the course of SCA, and especially morphological variations, will be helpful for the clinical branches in preventing complications during surgical operations, evaluating angiographic examinations, and diagnosing and treating neurovascular diseases.

Unilateral Çift Arteria Superior Cerebelli Varyasyonu: Bir Kadavra Vaka Raporu

Abstract

Arteria superior cerebelli (ASC), beyin sapının önünde bulunan bir damar olup genellikle arteria basilaris (AB)’ten köken alır. Bu olguda 74 yaşındaki erkek bir kadavrada sol ASC’nin farklı seyri bildirilmektedir. ASC’nin kökeninin sol tarafta pons’un ön yüzünde unilateral çift kök halinde olduğu tespit edildi. Köklerin başlangıç noktalarının bifurcatio basilaris’e olan uzaklıkları sağ tarafta 31,09 mm, sol tarafta üst kök 33,84 mm ve alt kök 30,95 mm idi. Sağ ASC çapı 2,37 mm, sol üst kökün çapı 2,05 mm ve alt kökün çapı ise 1,24 mm idi. ASC’nin seyrinin ve özellikle morfolojik varyasyonların bilinmesi, cerrahi operasyonlar sırasında komplikasyonların önlenmesinde, anjiografik tetkiklerin değerlendirilmesinde ve nörovasküler hastalıkların teşhis ve tedavisinde klinik branşlara faydalı olacaktır.
