The most commonly injured vessels were the internal iliac artery stem in 6 cases, inferior gluteal artery
in 6 cases, and superior gluteal artery
in 6 cases.
Specific topics include free fibula flap for midface reconstruction, lower eyelid reconstruction with palatal grafts, free flap for hemi-tongue reconstruction, skate flap for nipple reconstruction, hernia repair with open component separation, superior gluteal artery
perforator flap, the medial plantar flap, and pediatric facial reinaimation using a functional gracilis muscle transfer.
Inferior gluteal artery
perforator vessels originate in the inferolateral quadrant [Figure 1].
The branches of the posterior trunk are the superior gluteal artery
, lateral sacral artery, and iliolumbar artery.
Complications with C-clamp placement include superior gluteal artery
and sciatic nerve injury if the spikes are inserted too distally [16,18,19].
After multidisciplinary agreement, the patient underwent urgent Digital Subtraction Angiography (DSA) that confirmed the three points of bleeding described on CT, that is, gluteal artery
, iliolumbar artery, and lumbar arteries (Figures 2(a) and 2(b)).
The inferior gluteal and first perforator arteries: The tibial portion of the sciatic nerve got arterial supply from the inferior gluteal artery
through its branch, that accompanied the posterior cutaneous nerve of the thigh (Fig.
Its blood supply is provided by the inferior gluteal artery
. The superior gluteal artery
, the first perforating artery of the profunda femoris, the lateral femoral circumflex artery, the lateral sacral artery, and the internal pudendal artery also contribute to muscle irrigation.
At surgery the defect measuring about 16 cm by 24 cm was encountered (Figure 1) An island posterior thigh flap based on the inferior branch of the inferior gluteal artery
was raised (Figures 2, 3, and 4).
Right internal iliac artery ligation was performed below origin of superior gluteal artery
to avoid claudication and hematuria subsided.
The parietal branches secured are the obturator artery, the inferior gluteal artery
and the internal pudendal artery.
