What is the primary blood supply to the trapezius flap?

• A. Subclavian artery
• B. Transverse cervical artery
• C. Brachial artery
• D. Axillary artery

Answer: (B)

The primary blood supply to the trapezius flap comes from the transverse cervical artery. This vessel branches off the thyrocervical trunk, which itself is a branch of the subclavian artery. The transverse cervical artery traverses laterally across the neck and provides vascular supply to the trapezius muscle, making it critical for the viability of this flap when used in surgical procedures. The trapezius flap is commonly used in reconstructive surgery due to its robust blood supply and the muscle’s ability to be mobilized without compromising its vascularity. The successful perfusion from the transverse cervical artery ensures that the flap can survive and function effectively after transfer. Other choices such as the subclavian artery, brachial artery, and axillary artery do not provide direct blood supply to the trapezius flap. While the subclavian artery is indeed a primary source of blood to many structures in the upper body, the specific nutrient supply to the trapezius muscle comes distinctly from the transverse cervical artery. The brachial artery primarily supplies blood to the arm and has no role in the trapezius flap's vascularization. The axillary artery supplies branches to the muscles around the shoulder, but again, it does not directly support the trape
