Supraclavicular Artery Flap
Özet
Supraclavicular artery-based flaps provide aesthetic and functional coverage for the head and neck region. Fourteen formalin-fixed cadavers were dissected bilaterally, and 28 supraclavicular arteries were evaluated. The origin of the supraclavicular artery was transverse cervical artery in 62.9% and suprascapular artery in 37.1% of the cases. The origin of the artery was at the level of the medial third of the clavicle in 3.7%; 3.7% of the cases were at the junction of medial and middle third of the clavicle, 33.3% at the level of middle third of the clavicle, 11.1% at the junction of middle and lateral thirds, 44.4% at the level of lateral third, and 3.7% at the level of acromioclavicular joint. The mean values of the results were as follows: The diameter of the artery was 1.0 mm at the origin. The distance of the origin of the artery from sternoclavicular joint and from the upper border of the clavicle was 76.4 and 22.2 mm, respectively. The average length of the artery was 70.8 mm. In all dissections, the artery was deep to the platysma muscle. Forty-one percent of supraclavicular arteries accompanied the middle supraclavicular nerve, whereas 59% of the arteries run with lateral supraclavicular nerve. The supraclavicular artery had a parallel course to the 2 horizontal imaginary lines passing from the coracoid process and acromion in 63% of the cases; 18.5% of the arteries were oblique, and 18.5% were vertical to the imaginary lines. The venae comitantes were double in all dissections.
