Orta serebral arterin önemli bir dalı; temporal arter: Anatomik çalışma

Amaç: Orta serebral arterin (a. cerebri media) literatürde çokça tartışılmamış dalı olan temporal arterin anatomik olarak kadavra üzerinde değerlendirilmesi ve kanlanmasını sağladığı temporal lobdaki (lobus temporalis) verdiği kortikal dalların dağılma paternlerinin ortaya konulması amaçlanmıştır. Gereç ve Yöntem: 27 insan beyni (54 hemisfer) üzerinde çalışıldı. Beyinlerin arterleri yıkandıktan sonra renklendirilmiş lateks ile doldurulmak suretiyle diseksiyona hazır hale getirildi. Temporal arter tanımlandı. Orjin aldığı yerler, verdiği kortikal dallar ortaya konuldu. Bu arterlerin çapları, sulama alanları ve birbirleri ile olan ilişkileri gösterildi. Bulgular: Temporal arterin hemen tüm hemisferlerde görüldüğü belirlendi. Temporal loba verdiği kortikal dalların 2 ila 4 adet dal arasında değiştiği görüldü. Hem temporal arterin, hem de verdiği kortikal dalların erken dal olarak orijin almaları durumunda arter çaplarının arttığı gösterildi. Sonuç: Temporal arter, anatomistlerin ve nöroşirürjiyenlerin çoğu zaman gözünden kaçan bir arter olmuştur. Hâlbuki, suladığı alanın önemi ve verdiği dallardaki değişken yapı göz önüne alındığında dikkate alınması gereken bir vasküler yapı olduğu düşünülmektedir.

Important branch of middle cerebral artery: An anatomical study

Aim: The temporal artery, the branch of middle cerebral artery is not thoroughly discussed in the literature. The aim of this study was to evaluate the temporal artery in cadavers and to define its branching pattern in temporal lobe, which was supplied by this artery. Materials and Methods: This study was performed on 27 human cadaveric brains (54 cerebral hemispheres). After irrigating brain arteries were injected with colored latex to be ready for dissection. The temporal artery was defined. Its origins and its cortical branches were demonstrated. The diameter, their supply areas and the relationships of the arteries with each other were indicated. Results: Temporal artery was determined in almost at all hemispheres. It was observed that number of the branches to the temporal lobe varies between two and four. It was established that diameters of the temporal artery as well as its cortical branches were increased if they originated as early branches. Conclusion: Temporal artery usually was neglected by anatomists and neurosurgeons. When the area of this artery supplies and variability of it branching pattern was taken in account, this artery should be taken into consideration.
