Foramen Transversarium’larında Kostal Elementleri Bilateral Olarak Bulunmayan Bir Atlas Olgusu

Anatomi laboratuvarında kostal elementleri bilateral olarak oluşmamış sıradışı bir atlas omuru tespit edildi. Normal gelişmiş bir atlasta arteria vertebralis’lerin ön taraftan processus transversus atlantis’in kostal elementlerince korunmasından dolayı foramina transversarium’ları düzgün gelişmeyip önden açık kalan hastalara cerrahi işlem sırasında daha çok dikkatli olunmalıdır. Arteria vertebralis gibi, bu arterin etrafında seyreden sinir ağının zedelenmesi de bu bölgenin cerrahileri sonrası çıkan komplikasyonlardan sorumludur.

A case of an atlas vertebra bilaterally without costal elements of transverse processes

An unusual atlas vertebra whose costal elements were not formed bilaterally was detected in an anatomy laboratory. Because the vertebral arteries have bony protections anteriorly by the costal elements of the transverse foramina of a usual atlas, surgical operations of the atlas’ without transverse foramina need much more attention while approaching to that region. As well as the vertebral artery, the nerve plexus around vertebral artery may also be responsible of some complications due to failure of this bony protection.
