“…13 The most common complications known in the case of KDPF are wound infection and dehiscence. 5,[13][14][15] This is probably due to the intrinsic tension at the suture line and through the central region of the flap. One option to avoid dehiscence at the closure line is to allow the donor site healing by secondary intention.…”

How to Transform a Perforator Propeller Flap into a Keystone Flap in Case of Unsatisfying Perforator Vessel Local Perforator Flap Coverage in Limbs

Moderate soft-tissue defects need stable coverage, ideally with tissue of similar characteristics and low donor site morbidity. We propose a simple technique for the coverage of moderate skin defects in the limbs. It allows intraoperative transformation of a propeller perforator flap (PPF) into a keystone design perforator flap (KDPF) in cases of unsatisfying perforator vessel or in cases of unpredictable intraoperative events. Between March 2013 and July 2019, nine patients with moderate soft-tissue defects (mean defect size 4.5 × 7.6 cm) in the limbs (two on the upper limbs and seven on the lower limbs) were covered using this technique. We performed four PPFs and five KDPFs. The mean follow-up was 5 months. There was one complication, partial distal tip necrosis in a PPF located in the leg, which healed by secondary intention within 3 weeks. The donor site was closed directly in all cases. No functional impairments were noted regardless of the perforator flap utilized. This technique enables us to employ flexible surgical strategies and allows us to make adjustments based on the patient's vascular anatomy.

“…El CK es un colgajo en isla fasciocutáneo propuesto de manera primaria para la corrección de defectos infrapatelares y permite el cierre en un acto quirúrgico único (defecto y zona donante) sin requerir autoinjertos cutáneos 4,7,8 . La reconstrucción de grandes defectos con escaso volumen y falta de laxitud de piel obliga a utilizar colgajos libres, técnicamente difíciles y con tasa elevada de fracasos.…”

La reconstrucción de defectos posoperatorios > 15 mm, ubicados en áreas con escasa movilidad o piel, puede representar un desafío. Algunas de estas áreas incluyen rodillas, piernas, pies, hombros, antebrazos y manos. El cierre primario puede no ser recomendable o posible, lo cual establece la necesidad de aplicar colgajos o injertos, estos últimos con resultados estéticos desfavorables. El colgajo fasciocutáneo keystone (CK) es una opción relativamente fácil para reparar defectos en estas regiones, con un período posoperatorio de recuperación rápido y resultados estéticos muy aceptables. El objetivo de este artículo es revisar paso a paso la técnica, indicaciones, ventajas y posibles complicaciones.
