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.

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.
