Abstrakt: Background: The lower extremities are the largest donor sites in the body for perforator flap reconstruction. Multislice row computed tomography angiography allows for a multiplanar assessment of perforators using a large number of three-dimensional images with high resolution. In this study, the effect of leg dominance on perforator flap donor site preference was investigated radiologically to increase preoperative perforator mapping precision and surgical success.
Patients and Methods: The study included 40 patients. Superior gluteal artery perforator (SGAP) flap, inferior gluteal artery perforator (IGAP) flap, superficial circumflex iliac artery perforator flap, anterolateral thigh (ALT) flap, profunda artery perforator (PAP) flap, medial sural artery perforator (MSAP) flap, peroneal artery perforator (PP) flap, and posterior tibial artery perforator (PTAP) flap were analyzed according to their number of perforators (> 0.8-mm perforators counted, number of larger perforators [nLP]), dominant perforator diameter (DPD), related muscle thickness (RMT), and related subcutaneous tissue thickness (RSTT) in each leg.
Results: Of these 40 patients, 35 (87.5%) were right-leg dominant and 5 (12.5%) were left-leg dominant. The dominant leg had higher DPD for MSAP, PTAP, and PP than the nondominant leg (p = 0.08, p = 0.06, and p = 0.06, respectively). The dominant leg had a significantly higher nLP (> 0.8 mm) in MSAP, PTAP, and PP flaps than the nondominant leg (p < 0.05). Except for the PAP flap (adductor magnus muscle; p > 0.05), RMT of all other perforator flaps (SGAP, IGAP, ALT, MSAP, PTAP, and PP) was statistically higher in the dominant leg (p < 0.05). There was no statistically significant difference in RSTT between any of the two groups (p > 0.05).
Conclusion: According to findings, the dominant leg could be considered a donor site preference to improve surgical outcomes and reduce microsurgical complications due to an increased nLP, perforator diameter, and RMT.
