MUSCULUS SUBCLAVİUS POSTICUS OLGUSU

Musculus subclavius posticus; arteria subclavia, vena subclavia ve plexus brachialis gibi önemli yapılara kom-şuluk eden, birinci kıkırdak kaburga ve scapula arasında yer alan aksesuar bir kastır. Anabilim dalımız anatomilaboratuvarında 60 yaşındaki erkek kadavrada boynun sol tarafında varyasyona rastlanmıştır. Musculus subc-lavius posticus varlığının çevre yapılara etkisi klinik açıdan önemlidir. Torasik Outlet Sendromu olarak adlan-dırılan bu durum üst ekstremite beslenmesinden sorumlu damarların ve innevasyonundan sorumlu plexusbrachialis'in dallarının sıkışmasına sebep olabilir. Literatüre göre nadir gözlenen bu varyasyonun yerleşimininbilinmesi, radyolojik ve cerrahi prosedürler için önem arz etmektedir.

Musculus Subclavius Posticus Case

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.
