ULNAR ARTERDEN ÇIKAN PALMAR TİP BİLATERAL KALICI MEDYAN ARTER OLGUSU

Üst ekstremitelerin arteryel anatomisi ve yaygın varyasyonları hakkında doğru bilgi, ekstremite cerrahları için çok önemlidir. Kalıcı medyan arter, 6 kadavrada (12 üst ekstremite) incelendi. Disseksiyon sırasında yüzeyel palmar kemerin oluşmadığı, bifid median sinirin ve ulnar arterden köken alan kalıcı medyan arterin olduğu bilateral bir olgu ile karşılaştık. Bu çalışmada, kalıcı medyan arterin insidansı %17 idi. Kalıcı medyan arter ve ulnar arterlerin, kadavranın her iki ekstremitesinde de bir kemer oluşturmadan avuç içini beslediği belirlendi. Bu örnek bir radyo-mediyo-ulnar tip-tamamlanmamış yüzeysel palmar kemer oluşumunu gösterdi. Ulnar arter, diğer damarlara göre hemen hemen tüm kadavralarda avuç içi baskın damardı. Avuç içi vasküler paternindeki varyasyonların bilinmesi, rekonstrüktif cerrahide klinik ve plastik cerrahlara önemli ölçüde yardımcı olacaktır, çünkü böyle bir arter karpal tünel sendromu gibi komplikasyonlara neden olabilir.

A CASE OF PALMAR TYPE OF BILATERAL PERSISTENT MEDIAN ARTERY ARISING FROM THE ULNAR ARTERY

Accurate information about the arterial anatomy of the upper extremities and their common variations is essential for limb surgeons. Persistent median artery (PMA) was examined in 6 cadavers (12 upper limbs). We encountered one case of bilateral the absence of superficial palmar arch (SPA), a bifid median nerve (MN) and the presence of the PMA originating from the ulnar artery (UA) during dissection. The incidence of the PMA in this study was 17%. It was determined that PMA and UA supplied the palm on both extremities of the cadaver without forming an arch. This specimen showed a radio-mediano-ulnar type of incomplete SPA. The UA was the dominant vessel of the palm in almost all cadavers compared to the other vessels. Awareness of variations in the vascular pattern of the palm will be of considerable help for clinical, plastic surgeons in their reconstructive surgery because such an artery may result in complications such as carpal tunnel syndrome.
