Figure 4. Case 4: (a) "X" denotes Doppler signal, "•" denotes MDCTA preoperative perforator localization; (b) plastic buttons at segments of thigh along AP line. Doppler signal at 3.5 cm and 5.5 cm above midpoint of AP line; (c) MDCTA axial section showing TBLCFAP; (d) sizable semi-septocutaneous perforator (TBLCFAP-ssc) 15 cm from ASIS and two other septocutaneous perforators DBLCFAP-s which correlated with preoperative MDCTA; (e) and (f) same TBLCFAP seen in coronal and sagittal sections. MDCTA: multi-detector row computed tomography angiography; TBLCFAP-ssc: semi-septocutaneous perforator arising from transverse branch of lateral circumflex femoral artery; DBLCFAP-s: septocutaneous perforator arising from descending branch of lateral circumflex femoral artery
