Abstract

ÖZET

Musculus subclavius posticus; arteria subclavia, vena subclavia ve plexus brachialis gibi önemli yapılara komşuluk

eden, birinci kıkırdak kaburga ve scapula arasında yer alan aksesuar bir kastır. Anabilim dalımız anatomi

laboratuvarında 60 yaşındaki erkek kadavrada boynun sol tarafında varyasyona rastlanmıştır. Musculus subclavius

posticus varlığının çevre yapılara etkisi klinik açıdan önemlidir. Torasik Outlet Sendromu olarak adlandırılan

bu durum üst ekstremite beslenmesinden sorumlu damarların ve innevasyonundan sorumlu plexus

brachialis'in dallarının sıkışmasına sebep olabilir. Literatüre göre nadir gözlenen bu varyasyonun yerleşiminin

bilinmesi, radyolojik ve cerrahi prosedürler için önem arz etmektedir.

ABSTRACT

Musculus subclavius is an accessory muscle located between the first cartilage rib and the scapula, adjacent

to important structures such as arteria subclavia, vena subclavia and plexus brachialis. In the laboratory of

anatomy department, a variation was found on the left side of the 60 years old male cadaver. The existence

of the musculus subclavius posticus is clinically important for the adjacent structures. This may cause thoracic

outlet syndrome, compression of the vessels responsiple for the blood supply and branches of the plexus

brachialis responsible for the innervation of the upper extremity. The knowledge of the location of this rarely

observed variation according to the literature is important for radiological and surgical procedures.
