Strategies for Complex Scalp Reconstruction in Patients With Poor Recipient Vessels

Complex scalp defects with poor recipient vessels represent a challenge for plastic surgeons. In these cases, free flaps are the last resort for solving the problem. The authors present 5 difficult cases with complex large scalp and calvarium defects with unsuitable small recipient vessels for anastomoses. For these cases, the lesser saphenous vein was harvested and used as an interposition graft between the external carotid artery, the jugular vein, and the flap. Latissimus Dorsi, Anterolateral Thigh, and serratus anterior were the flaps used for reconstruction. Cranioplasty was simultaneously performed in 4 cases. The scalp defects varied from 83 to 288 cm2. All flaps survived. In 1 case (extended Latissimus Dorsi) there was local infection and wound dehiscence with marginal flap necrosis that required flap readvancement. In conclusion, end-to-end anastomosis to the external carotid artery offers strong outflow through the vein graft and flap. A large vein graft allows good outflow and is more resistant to the pressure of the skin envelope. Anastomosis to large neck vessels (internal or external jugular) facilitates drainage since there is also an aspiration effect due to the venous flow circulation through it.
