Thoraco-Acromial Artery : A Cadaveric Study Of Its Pedicle And Branches

Background of study- A detailed knowledge of variations in the origin and branching pattern of Thoraco-acromial artery(TAA) is important during various reconstructive and microvascular surgeries. Materials and methods- Hundred formalin xed specimens were studied at Government Medical College, Kozhikode, Kerala, India over a period of four years. Results- Normal quadrifurcation pattern was observed in majority of specimens (84%). The division of TAA into two trunks was seen in 9% followed by ramication into multiple branches in 4% specimens. Some specimens showed trifurcation (3%). Conclusion- In this scenario of increasing reconstructive surgeries, a thorough knowledge on the anatomical variations of TAA will be helpful to surgeons as this artery provides vascular supply to Pectoralis Major Myo-Cutaneous ap.
