Groin flap and superficial circumflex iliac artery
Further, the inferior epigastric artery frequently arises indirectly from external iliac artery as from a common trunk with other arteries such as deep circumflex iliac artery
, the obturator artery (Kawai et al., 2008 & Hussein et al., 2013) or with the obturator and medial circumflex femoral arteries (Sanudo et al., 2011).
Their topics include the history of the use of perforator flaps for microsurgical breast reconstruction, essential equipment needed for perforator flap breast reconstruction and operating room setup, gluteal artery perforator flap, free lumbar artery perforator flap for autologous breast reconstruction, bipedicled (doubled for stacked) abdominal perforator flap in unilateral breast reconstruction, deep circumflex iliac artery
perforator flap, and indocyanine green/SPY imaging.
Groin flap has axial pattern blood supply from the superficial circumflex iliac artery
(SCIA), and thus it can be raised on a narrow base which contains the vascular pedicle.
The deep circumflex iliac artery
arises from the lateral external iliac artery nearly opposite to the IEA, for which it is a good landmark.
