Bilateral arcus axillaris case

Rutin kadavra disseksiyonu esnasında 55 yaşında bir erkek kadavrada bilateral arcus axillaris'e rastlandı. Literatürlerde “Arcus axillaris”, “Aksillopektoral kas” veya “Langers'in aksillar arkı” olarak da bildirilen bu yapı fibröz yada muskuler karakterde olabilmektedir. Bizim olgumuzda m. latissimus dorsi'den ayrılan bir kas demeti aksillar damar sinir paketinin önünden geçip m. pectoralis major'un tendonunda sonlanıyordu. Sol muskuler ark interkostobrakiyal sinir tarafından innerve edilmesine karşın sağ taraftakini innerve eden herhangi bir sinire rastlanmadı. Arkus aksillaris, kol, ön kol ve elde nörovasküler semptomlara yol açabilmektedir.

Bilateral arkus aksillaris olgusu

Bilateral arcus axillaris was found on a 55-yearold male cadaver in our laboratory of anatomy during routine dissection. This variation which is also called as axillary arch, axillopectoral muscle or axillary arch of Langer could be fibromuscular or muscular. In our case, a fasciculus separating from latissimus dorsi muscle ended at the tendon of pectoralis major muscle after overlying the neurovascular bundle in the axilla. Althought left muscular arch was innervated by intercostobrachial nerves, right muscular arch's nerve was not identified. It might have caused neurovascular symptoms in the hand, arm and forearm.
