ABSTRACT
BACKGROUND:
Chimeric osteomyocutaneous flaps harvested from the subscapular artery system have been used in clinical practice. We describe the use of a novel circumflex scapular artery myocutaneous and/or vascularized scapular chimeric flap in a rat model and demonstrate optimal skin flap dimensions. MATERIALS ANDMETHODS:
An 8 × 4-cm-rectangular skin flap based on the circumflex scapular artery flap was harvested, and the mean percentage of the surviving flap area and the necrotic area were calculated to be 71% ± 17.9% and 29% ± 17.9%, respectively. Using flap dimensions determined in the first part of our study, a 4 × 3-cm quadrangular portion of skin was marked over the scapula, and the serratus anterior muscle and a portion of the scapular bone were included in our chimeric flap model.RESULTS:
The mean percentages of the surviving flap and necrotic areas were 74% ± 6% and 25% ± 6%, respectively. Microangiographic and histologic studies revealed the vascularity of the skin island and identified the branches of the circumflex scapular artery that supplied the bone and muscle.CONCLUSIONS:
The circumflex scapular artery myocutaneous and/or vascularized partial scapular chimeric flap may be considered a branch-based chimeric flap and can be an acceptable flap model due to its simplicity, reliability, and consistent vascularity. Furthermore, this flap may have potential applications in studying chimeric flap hemodynamics.Palavras-chave
