Abstract:
Arterialized venous flow-through flaps are solely vascularized through the venous plexus. The flaps were first described 40 years ago; however, reports of venous congestion and ischemia discouraged surgeons from adopting them into their armamentarium. Nevertheless, recent studies have demonstrated a resurgence of venous flow-through flaps for reconstruction of small to medium defects of the hand and digits. Although current data report variable levels of success in adults, no case reports have been published in the pediatric population for this type of flap. In this study, an arterialized venous flow-through flap from the medial forearm was used to reconstruct a volar hand defect in a young child. Flap markings, surgical technique, and aftercare are described. The surgery was uncomplicated, and the postoperative outcomes were aesthetically and functionally excellent. Venous flow-through flaps restore full-thickness defects, are relatively easy to perform, allow an early return to daily activities, and have almost no morbidity. These flaps offer excellent options for pediatric hand and finger defects.
