Trigeminal Sinire Vasküler Temasın Araştırıldığı Bir Kadavra Çalışması

Öz

Amaç: Trigeminal sinirin sisternal segmenti içinde kök varyasyonları, roor enter zone’a vasküler basının normal popülasyondaki dağılımını araştırmak.Gereç ve Yöntemler: Basit rastgele örneklem metoduyla seçilmiş 30 taze kadavrada, 60 trigeminal sinir, trigeminal sinir beyinsapı çıkış noktasından, Mekcel’s cave giriş noktasına kadar binoküler lup ile mikrocerrahi set kullanılarak araknoid diseksiyonu yapılmıştır. Sisternal segment içinde trigeminal sinirin ve vasküler yapılarla olan komşuluk ilişkileri ve tipleri araştırıldı. Bulgular: 30 vasküler temasın saptandığı olgularda 22 %73,3 ’sinde arter, 8 %26,6 ’inde venöz yapılar görüldü. Arteriel yapıların 14 %46,6 ’ünde süperior cerebellar arter, 8 %26,6 ’inde anterior inferior cerebellar arter olarak tanımlandı. Süperior petrozal ven, trigeminal sinire venöz temastan sorumlu bulunmuştur.Sonuç: Bu kadavra çalışmasının sonuçlarına göre vasküler temas insidental olarak normal populasyonun %50’sinde görülmektedir

A Cadaver Study for Investigating Vascular Contact with the Trigeminal Nerve

Abstract

Objective: The present study investigates root variations within the cisternal segment of the trigeminal nerve and the distribution of vascular compression at the root entry zone in a normal population. Material and Methods: In total, 60 trigeminal nerves taken from 30 fresh cadavers, selected based on a simple random sampling method, were dissected with an arachnoid dissection from the exit point of the trigeminal nerve from the brainstem until the point of entry to Meckel’s cave using a binocular loop and microsurgery set. The vicinity of the vascular structures and the types of trigeminal nerve in the cisternal segment were investigated. Results: In total, 30 cases of vascular contact were detected, involving arterial and venous structures in 22 73.3% and 8 26.6% cases, respectively. Arterial structures were defined as the superior cerebellar artery and the anterior inferior cerebellar artery in 14 46.6% and 8 26.6% cases, respectively. The superior petrosal vein was found to be responsible for venous contact to the trigeminal nerve.Conclusion: The results of this cadaveric study showed that vascular contact could be incidentally found in 50 percent of the normal population
