ABSTRACT
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 ramication 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.
ABSTRACT
BACK GROUND OF STUDY:A detailed awareness of branching pattern of left main coronary artery is of immense help for various diagnostic and therapeutic measures on coronary arteries, in this era of increasing coronary artery disease. MATERIALS & METHODS: Fifty human hearts were included in the study group. The LMCA and its branches were studied in detail after removing the epicardium and subepicardial fat. RESULTS: This dissection study on the ramification of LMCA could detect bifurcation , trifurcation and quadrifurcation in 76%, 22% and 2% respectively.
