OBJECTIVETo explore the feasibility and the effect of free chimeric perforator flap with deep inferior epigastric artery for the soft tissue defect on the lower extremity with deep dead space.
METHODSFrom Mar. 2010 to Aug. 2011, 8 patients with soft tissue defects on the lower extremities combined with dead space, bone or joint exposure were reconstructed with free hinged perforator flaps with deep inferior epigastric artery. The muscle flap was inserted into the deep dead space, with perforator flap for superficial defect. The defects on the donor sites were closed directly.
RESULTSAll the flaps survived with primary healing. Good color and texture was achieved. The patients were followed up for 12-24 months, with an average of 16 months. 2 over-thick flaps were treated by flap-thinning surgery. Only linear scar was left on the donor site on abdomen with no malfunction.
CONCLUSIONSThe free chimeric perforator flap with deep inferior epigastric artery can simultaneously construct the dead space and superficial defect with only anastomosis of one set of vascular pedicle. It is an ideal method with good results on recipientsites and less morbidity on donor sites.

Objective To describe a technique to achieve primary donor-site closure, extend applications and minimize donor-site morbidity by applying the double skin paddle principle.Methods All 16 cases of the double skin paddle anterolateral thigh perforator flap reconstruction from May, 2008 to June, 2014 were reviewed.Defects locations included calf, dorsum pedis or planta pedis.A long anterolateral thigh perforator flap was marked out using standard points of reference.At least two separate cutaneous perforator vessles were identified on hand-held Doppler.Separating and dissecting flap at superficial layer of fascia lata was adopted in all cases.Then skin paddle was then divided between the two cutaneous perforators to give two separate paddles with a common vascular supply which was the descending branch of the lateral circumflex femoral artery.The skin paddles could be used to cover complex skin defects, whilst still allowing for primary donor-site closure.Results Fifteen patients were successfully treated with the double skin paddle anterolateral thigh perforator flap with no major complications.One case was suffered with partial skin flap necrosis.The type A dumbbell-like flaps was used to cover defects involving two different units of the foot.The type B pattern were stacked side by side on a flap inset, effectively doubling the width of the flap, to resurface a large defect of a single unit of the calf.The type C pattern was used to repair adjacent skin defects.In all cases, the donor site was closed directly.All patients were satisfied with their outcomes.Conclusion The double skin paddle anterolateral thigh perforator flap is an excellent method of resurfacing large defects of the extremity involving multiple subunits with improved morbidity and cosmesis of the donor site.

Objective:To introduce a novel surgical technique for dissecting perforator vessels (orderly retrograde four-side dissection) in anterolateral thigh perforator flap (ALTPF) and explore its clinical outcome.Methods:Respective analysis of 94 patients who underwent reconstruction of soft tissue defects with ALTPF which were dissected by orderly retrograde four-side dissection between June, 2013 and December, 2016. After surgery, the survival of flaps, recovery in shape and function of the recipient sites, and the effect on shape and function of the donor sites were observed.Results:The size of ALTPF ranged from 7 cm×5 cm to 32 cm×10 cm. Ninety-four perforators were included in 94 ALTPF, which were 89 perforators of the descending branch of circumflex femoral lateral artery, 4 perforators of the transverse branch of circumflex femoral lateral artery and 1 perforator of femoral medial artery. The time for flap harvesting was 35-95(54.39±16.39) min. Success rate of perforator harvesting was 98.9%, only 1 perforator was injured and another encountered vasospasm during surgery. Three cases had vascular crisis after flap transfer with 2 venous crises and 1 artery crisis. All of the flaps completely survived except 1 that had a partial necrosis. The follow-up time was (12.91±9.17) months. No muscular weakness on donor sites was shown in all cases.Conclusion:Orderly retrograde four-side dissection of perforator vessels in the ALTPF has achieved less donor site morbidity, shorter surgical time and is safer than the traditional techniques. It is a reliable technique to harvest perforator flaps.
