Fig. 1.
Pedicle options for the ALT flap in the context of SFA occlusion. The distal SFA was reconstituted from genicular collaterals (green) and collaterals from the PFA (purple). Sites of arterial occlusion are in yellow. A, Perforators from the descending branch of the lateral circumflex femoral artery (DCFA). B, Perforator from the transverse branch of the lateral circumflex femoral artery (TCFA). Gray claps on the figure mark sites of arterial branch clamping as described.
