Rare atypical vascular pattern of subscapular artery: Anatomico-clinical insight.

BACKGROUND AND OBJECTIVE: The use of muscles of scapular region in transposition and reparative surgery has made the anatomical knowledge of axillary artery and its branches imperative. The subscapular arterial tree is frequently used as a source of microvascular grafts to replace damaged or diseased portion of arteries especially in upper and lower limbs. This investigation is aimed to study the variation in branching pattern of the third part of axillary artery. MATERIALS AND METHODS: Routine educational cadaveric dissection of a young adult Indian male cadaver. RESULTS: The present article highlights a rare variation of the subscapular artery and its branches. The subscapular artery displayed a unique pattern of trifurcation. Its branches were seen supplying serratus anterior, subscapularis, latissimus dorsi and teres major muscles. CONCLUSIONS: The study focuses on a new variation of the subscapular artery which could prove useful for interventional radiologists and surgeons in reconstructive surgeries.

Unilateral atypical disposition of femoral vessels: clinico- embryological annotations.

The boundaries and contents of femoral triangle constitute an important lesson in gross anatomy teaching to undergraduate medical students. Apart from this, the normal disposition of the femoral vessels in the femoral triangle is vital for planning certain operating maneuvers in this region. Femoral vessels are very frequently utilized, during various surgical and clinical procedures. Thus, the precise knowledge of the normal anatomy as well as the variations in the femoral vessels is important for surgeons and anatomists. We report a unilateral variation in the disposition of femoral vessels in the femoral triangle, in a 42 yr old male formalin- preserved cadaver. The femoral artery traversed anterior to femoral vein to occupy a medial position in close proximity to the Sapheno-femoral junction. The embryological and clinical implications of the observed variation are discussed.
