  • Application of Endoscope in Treatment for Venous Ulcer in Lower Limb

    ObjectiveTo evaluate the clinical experiences and treatment effectiveness of chronic venous insufficiency with venous ulcer in lower limb. MethodsSeventy-eight patients (88 limbs) suffering lower limb chronic venous insufficiency with venous ulcer from May 2004 to April 2011 in this hospital were analyzed retrospectively. All the patients had undergone high ligation for great saphenous vein plus endovenous laser treatment plus subfascial endoscopic perforator vein surgery (SEPS). ResultsPostoperative complications included 3 cases of subfascial haematoma; 2 cases of pneumohypoderma; 3 cases of numbness in anterior tibial and ankle areas. All the ulcers healed between 4 to 6 weeks. Follow up period was between 6 months to 5 years. There was only one recurrence due to residual varicose from ankle area. The mean operation time was 20 min (15-30 min) in SEPS, the average blood loss was 2 ml (1-5 ml), and the mean duration of postoperative hospitalization was 5 d (2-8 d). ConclusionsSEPS is a first treatment choice for CVI with venous ulcer. It has less invasiveness, lower chances for bleeding, shorter operation time, quicker recovery, and fewer complications.

    【Abstract】 Objective To investigate the method and effectiveness of expanded delto-pectoral and abdominalperforator flaps in repairing large defects of the face and upper limb after scar excision. Methods Between August 2000 and February 2011, 25 patients with large scars on face and upper l imb were treated. There were 14 males and 11 females with an average ageof 27 years (range, 7-36 years). Scars causes were burn and scald in 25 cases with a disease duration of 6 months to 7 years (mean, 4.5 years). The hypertrophic scars located at face in 15 cases, and at upper limb and hand in 10 cases. The soft tissue expanders (300-500 mL in volume) were implanted in the delto-pectoral zone and abdominal region in one-stage operation. In two-stage operation, after scars were resected, defects (9 cm × 7 cm to 17 cm × 8 cm) were repaired with the delto-pectoralperforator flaps (17 cm × 7 cm to 20 cm × 8 cm) in 15 facial scar cases and with the deep inferior epigastric artery perforator flaps (10 cm × 9 cm to 25 cm × 14 cm) in 10 upper limb and hand scar cases. The donor sites were sutured directly. Results Partial necrosis of the flaps occurred in 2 cases after operation, then the flap survived after expectant treatment. The other flaps and skin grafts survived successfully, and the incisions healed by first intention. Ten patients were followed up 6 months to 4 years. Theappearance, texture, and color of the flaps were similar to those at the donor site. Conclusion It is an effective method to use the delto-pectoral perforator flap and the deep inferior epigastric artery perforator flap for repairing soft tissue defects of the face and upper limb after scar excision.

  • REPAIR OF SOFT TISSUE DEFECTS OF LOWER EXTREMITY BY USING CROSS-BRIDGE CONTRALATERAL DISTALLY BASED POSTERIOR TIBIAL ARTERY PERFORATOR FLAPS OR PERONEAL ARTERY PERFORATOR FLAPS

    Objective To discuss the feasibil ity of repairing soft tissue defects of lower extremity with a distally based posterior tibial artery perforator cross-bridge flap or a distally based peroneal artery perforator cross-bridge flap. Methods Between August 2007 and February 2010, 15 patients with soft tissue defect of the legs or feet were treated. There were 14 males and 1 female with a mean age of 33.9 years (range, 25-48 years). The injury causes included traffic accident in 8 cases, crush injury by machine in 4 cases, and crush injury by heavy weights in 3 cases. There was a scar (22 cm × 8 cm atsize) left on the ankle after the skin graft in 1 patient (after 35 months of traffic accident). And in the other 14 patients, the defect locations were the ankle in 1 case, the upper part of the lower leg in 1 case, and the lower part of the lower leg in 12 cases; the defect sizes ranged from 8 cm × 6 cm to 26 cm × 15 cm; the mean interval from injury to admission was 14.8 days (range, 4-28 days). Defects were repaired with distally based posterior tibial artery perforator cross-bridge flaps in 9 cases and distally based peroneal artery perforator cross-bridge flaps in 6 cases, and the flap sizes ranged from 10 cm × 8 cm to 28 cm × 17 cm. The donor sites were sutured directly, but a spl it-thickness skin graft was used in the middle part. The pedicles of all flaps were cut at 5-6 weeks postoperatively. Results Distal mild congestion and partial necrosis at the edge of the skin flap occurred in 2 cases and were cured after dressing change, and the other flaps survived. After cutting the pedicles, all flaps survived, and wounds of recipient sites healed by first intention. Incisions of the donor sites healed by first intention, and skin graft survived. Fifteen patients were followed up 7-35 months with an average of 19.5 months. The color and texture of the flaps were similar to these of the reci pient site. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system, the mean score was 87.3 (range, 81-92). Conclusion A distally based posterior tibial artery perforator cross-bridge flap or a distally based peronealartery perforator cross-bridge flap is an optimal alternative for the reconstruction of the serious tissue defect of ontralateral leg or foot because of no microvascular anastomosis necessary, low vascular crisis risk, and high survival rate.

    Objective To summarize the cl inical effect of anterolateral thigh pedicle or free perforator flap in repairing soft tissue defect in the extremities. Methods From March 2000 to January 2009, 32 cases of soft tissue defect were treated with pedicle or free anterolateral thigh perforator flap. There were 30 males and 2 females with an median age of28 years (4-53 years). Soft tissue defects included left radial side in 3 cases, the left lateral elbow in 1 case, knee in 5 cases, calf in 14 cases, dorsal is pedis in 5 cases, and planta pedis in 4 cases. The defect area ranged from 9 cm × 6 cm to 15 cm × 13 cm. Nine cases compl icated by bone defect and 1 case by radial nerve defect. The time from injury to hospital ization was 1 hourto 4 months (mean 5 days). Defects in 27 cases were repaired by anterolateral thigh perforator flap, simultaneously combined with transplantation with the second toe in 1 case, with sural nerve using arterial ized small saphenous vein in 1 case, nd with fibular or il ium in 4 cases. Defects in other 5 cases were repaired with flaps pedicled with superior lateral genicular artery. Neuroanastomosis was performed in 14 cases of the flaps. The size of the flaps ranged from 10 cm × 8 cm to 16 cm × 15 cm. Skin defects at donor site were repaired with spl it thickness skin graft or sutured directly. Results All patients were followed up from 8 months to 9 years with an average of 18 months. The flaps survived well and the wounds healed by first intention in 29 cases, 3 flaps necrosed and cured after symptomatic management. Skin graft at donor site survived completely in 9 cases. The color and texture and thickness of the flaps were similar to those of recipient site. After 6 months, the sensation of the flaps recovered to grade S3-4 in 14 patients whose cutaneous nerve were anastomosed, partial recovery was observed in other patients. In 4 patients receiving transplantation of fibular or il ium, the bony heal ing was achieved within 4 to 6 months. No obvious dysfunction was found at the donor site. Conclusion The pedicle anterolateral thigh perforator flap is long and thick with constant location. Anastomosis or transferring is easy to perform.

    Objective To investigate the operative technique and cl inical results of repairing the soft tissue defects of knee with antegrade extended peroneal artery perforator flap. Methods From October 2007 to January 2008, 3 patients (2 men and 1 woman) with the soft tissue defects of knee were treated, with the ages of 18, 31 and 42 years, respectively. The first casesustained femur and pelvis fractures and soft tissue defect over his right popl iteal fossa, which were treated with open reduction and internal fixation (ORIF) and debridement of knee joint 2 weeks ago. The second case was necrosis of skin 3 weeks after ORIF for fracture of tibial plateau. The third case suffered from open fracture of tibial plateau and soft tissue defect, which were treated with external fixation and debridement 3 weeks ago. The defect sizes were 16 cm × 9 cm, 11 cm × 6 cm and 14 cm × 7 cm. The flap was raised by dividing the peroneal artery and veins distally and elevating them proximally, which covered for the defects of knee. The flaps were designed with the size of 18 cm × 10 cm, 12 cm × 7 cm and 15 cm × 8 cm. The pure vascular pedicle of the flap was 10 cm to 17 cm in length, including the peroneal vessels and one or two perforator branches. The donor site is covered by a spl it thickness skin graft. Results All flaps survived after surgery. The donor sites healed by first intention and the skin grafts survived. After following up for 6, 8 and 11 months, the appearance and function of the flaps were all satisfactory. Based on the modified HSS knee performance system, post-operative knee functional outcomes of three patients were excellent. Conclusion The antegrade extended peroneal artery perforator flap suppl ied by a pure vascular pedicle can be a good alternative for reconstruction of knee.

  • CLINICAL APPLICATION OF FREE PERONEAL PERFORATOR-BASED SURAL NEUROFASCIOCUTANEOUS FLAP

    【Abstract】 Objective To investigate the operative techniques and cl inical results of repairing the soft tissue defectsof forearm and hand with free peroneal perforator-based sural neurofasciocutaneous flap. Methods From May 2006 toJanuary 2007, 6 patients including 5 males and 1 female were treated. Their ages ranged from 22 years to 51 years. They were injured by motor vehicle accidents (2 cases), or crushed by machines (4 cases), with skin defect of hand in 1 case, skin defect of hand associated with tendon injuries and metacarpal fractures in 2 cases, skin defect of forearm in 2 cases, and forearm skin defects with fractures of radius and ulna in 1 case. The areas of soft tissue defect ranged from 16 cm × 7 cm to 24 cm × 10 cm. The debridement and the primary treatment to tendons or bones were performed on emergency. And free flaps were transplanted when the wound areas were stable at 4 to 7 days after the emergent treatment. During the operation, the flaps were designed along the axis of the sural nerve nutrient vessels according to the shape and size of the soft tissue defects, with the peroneal perforator above the lateral malleolus as the pedicle and along with a part of the peroneal artery for vascula anastomosis. Then the flaps were harvested and transferred to the reci pient sites with the peroneal vartey anastomosed to the radial (or ulnar) artery and the peroneal veins to one of the radial (or ulnar) veins and the cephal ic vein, respectively. The flap size ranged from 18 cm × 8 cm to 25 cm × 12 cm. The donor areas were closed by skin grafts. Results The 5 flaps survived after the surgery. Partial inadequate venous return and distal superficial necrosis happened in only 1 case, which also got secondary heal ing by changing dressing and anti-infective therapy. The donor sites reached primary heal ing completely. The followed-up in all the patients for 6 to 13 months revealed that the appearance and function of the flaps were all satisfactory, and no influence on ambulation of donor site was found. Conclusion Peroneal perforator-based sural neurofasciocutaneous flap has the advantages of favourable appearance, constant vascular pedicle, rel iable blood supply, large size of elevation and minor influence on the donor site. And the free transfer of this flap is an ideal procedure to repair the large soft tissue defects of forearm and hand.

  • VAGINAL RECONSTRUCTION WITH MODIFIED PUDENDAL-THIGH FLAP

    Objective To increase the success rate of vaginal reconstruction with pudendal-thigh flap, reduce the chance of hemocirculatory disorder and rel ieve the deformity of greater l ip of pudendum and vaginal orifice. Methods FromJune 1998 to May 2004, 15 patients, 2 males with transsexual ism and 13 females with vaginal absence, aged 23-31 years old (26.2 on average), received vaginal reconstruction. Arterial perforator was detected at 3 cm laterally away from the mid-point between the vaginal orifice and the anus. The flap of 12.0 cm × 5.5 cm was designed at the lateral of the greater l ip of pudendum, with the groin as the axis. After the flap was elevated beneath the deep fascia, the fascial pedicle was partially severed from lateral to medium, keeping the perforator intact into the flap. Then the flap was transferred through the tunnel to the socket. The inner layer and the orifice were formed. Results All flaps survived, and the contour of the vulva was satisfactory. Among the 15 patients, 14 patients’ incisions obtained heal ing by first intention, and only 1 male with transsexual ism was discovered to suffer from rectovaginal fistula at the remote juncture of the two flaps at 7 days after the operation. By taking out all the gauze and cleaning the feces, the fistula healed automatically. All patients were followed up for 6 months-3 years. The reconstructed vagina was about 10 cm deep and 2 fingers wide. One female’s vagina was found pilous at 20 months after the operation, and no special treatment was given. The other patients’ vaginal inner walls were smooth and complete. Two female patients had the experienceof sexual intercourse and felt satisfied after using lubricant. Conclusion The modified pudendal-thigh flap has rel iable blood supply and makes the transferring during vaginal reconstruction more convenient and the contour of the vulva more satisfactory.

    Objective To investigate the method, effectiveness, andclinical application of the anterolateral thigh perforator free flaps for reconstruction of the soft tissue defects in the head and the four limbs after tumorresection. Methods From April 2004 to April 2006, 16 patients (13 males, 3 females; aged 26-72 years) with the soft tissue defects in the head (9 patients) and the four limbs (7 patients) underwent reconstructive operations with the anterolateral thigh perforator free flaps after their tumor resection. The defects ranged in area from 8 cm×6 cm to 20 cm×13 cm in the head with the process of diseases from 6 to 24 months, and the defects ranged in area from 10 cm×7 cm to 21 cm× 12 cm in the four limbs with the process of diseases from 2 to 18 months.The technique for the anterolateral thigh perforator flap freegrafting, the degree of the injury in the donor sites, and the appearance of the donor and recipient sites, and the influence on the anatomy and function in the both local sites were analyzed. Results In the 16 patients with the soft tissue defects in the head and the four limbs after tumor resection, 14 had a primary wound healing (Stage Ⅰ), and 2 had a delayed wound healing (Stage Ⅱ) . Fifteen flaps survived completely but two flaps had a partial failure. Theflap appearance was good and smooth without any severe scarring, and there was a minimal effect on the function at the donor and recipient sites. Conclusion Because of the less morbidity at the donor site, the better result at the recipient site, and the use of the anterolateral thigh perforator flap free grafting, this kind of the technique for reconstruction of the head and fourlimb soft tissue defects after tumor resection is well acceptable.
