Chest wall reconstruction using a turbocharged chimaeric anterolateral thigh flap.

Abstract

Extremely large chest wall defects may result following salvage oncological surgery. Typically these defects involve a large skin defect combined with a variable resected area of underlying muscle and ribs. In situations where the skin defect is very large the use of a large latissimus dorsi flap may require skin grafting to the donor site if a myocutaneous flap is used or to the recipient defect if a muscle-only flap is used. Alternatively a transverse rectus abdominis flap is a second option but in certain cases this may not be available. We describe the use of a free anterolateral thigh flap to reconstruct a chest wall defect and demonstrate the principle of side-to-side stacking of separate skin paddles to achieve skin closure of a massive defect whilst permitting primary closure of the donor site. The principle of turbocharging components of a chimaeric flap is also described.
