ObjectiveTo investigate the operative method of repairing soft tissue defect of the thumb with modified radial dorsal fasciocutaneous flap and its effectiveness.MethodsBetween June 2015 and December 2016, 15 patients with volar or dorsal defects of the thumb were treated with modified radial dorsal fasciocutaneous flaps which distal pedicles were cut off. Of 15 cases, 11 were male and 4 were female, aged 35-70 years (mean, 46 years). The causes of injury included crush injury in 12 cases and avulsion injury in 3 cases. Because all patients had volar or dorsal defects of the thumb which were accompanied by tendon or bone exposure, they had no condition or desire to replant. There were 12 cases of volar defect of thumb and 3 cases of dorsal defect. The area of defects ranged from 2.0 cm×1.2 cm to 3.0 cm×2.5 cm. The time between injury and operation was 16 hours to 2 days (mean, 30.4 hours). The radial dorsal fascio-cutaneous flaps of 2.3 cm×1.5 cm to 3.3 cm×2.8 cm in size were adopted to repair defects. The donor sites were directly sutured.ResultsAll flaps survived, and no severe swelling or tension blister occurred. The donor sites and wounds healed by first intention. All patients were followed up 3-12 months (mean, 6 months). The color and texture of the grafted flaps were similar to those of normal skin, with no bloated appearance. According to total active motion standard at last follow-up, the finger function was excellent in 8 cases and good in 7 cases.ConclusionModified radial dorsal fasciocutaneous flap of the thumb is a reliable flap with easy dissection and less trauma in repair of soft tissue defects of the thumbs, and satisfactory clinical outcome can be obtained.
Considering the abundant vascular anastomotic networks in the deep fascia of the posterior calf, three kinds of distally based facial flap containing deep fascial vascular network were applied clinically. They were: 1. posterolateral distally based island fascial flap which could be used to repair the skin defect of heel, dorsum of foot and lateral-distal part of leg; 2. posteromedial distally based island fascial flap which could be used to repair the skin defect of heel, medial malleolus and medial-distal part of leg and 3. posterolateral malleolar distally based fascial flap which could be used to repair the skin defect of heel and lateral malleolus. Eighteen cases with soft tissue defects around the distal calf were treated, the area of skin defect ranged from 4 cm x 3 cm to 13 cm x 6 cm. All the flaps were survived completely after operation with an average of follow-up for 15 months (ranged from 6 months to 2 years). So the advantages of these flaps were as follows: the blood supply was reliable, preparation of the flap was easy and the major arteries of the calf needed not be sacrificed; the flap had a long and rotatable pedicle so that they would basically satisfy the need to repair skin defect of lower leg, dorsum of foot, heel and malleolus and the resistance of the flap to pressure and wear was better. However, the injury to the superficial sural nerve was the shortcoming.

Objective To evaluate a modified anterolateral thigh fascial flap designed for the treatment of the soft tissue defects in the forearmsand hands. Methods From September 2000 to December 2003, a modified anterolateral thigh fascial flap combined with the intermediate split thickness skin graft was applied to the treatment of 13 patients with the soft tissue defects in the forearms or the hands. There were 8 males and 5 females, aged 19-43 years (average, 27.6 years). Three patients had a mangled injury, 4 had a belt injury, and 6 had a crush injury; 6 patients had their tissue defects on the palm side of the forearm, 6 had their tissue defects on the dorsal side of thehand, and 1 had the defect in the index finger (dorsal side of the hand). The tissue defects ranged in size from 17.5 cm×7.7 cm to 4.6 cm×3.4 cm.In addition, 4 of the patients had an accompanying fracture in the forearm or the hand,and the remaining 9 had an extenor tendon injury. All the patients underwent emergency debridement and reposition with an internal fixation for the fracture; 3-5 days after the repair of the injured nerves, muscle tendons and blood vessels, the tissue defects were repaired with the anterolateral thigh fascial flap combined with the intermediate split thickness skin graft. Results No vascular crisis developed after operation. All the flaps survived except one flap that developed a parial skin necrosis (2.0 cm ×1.0 cm) in the hand, but the skin survived after another skingrafting. The follow-up for 3-12 months revealed that all the flaps and skin grafts had a good appearance with no contracture of the skin. According to the evaluation criteria for the upper limbs recommended by the Hand Society of Chinese Medical Association, 9 patients had an excellent result, 2 had a good result, 1 had a fair result, and 1 had a poor result, with a good/excellence rate of 85%. Conclusion The modified anterolateral thigh fascial flap combined with the skin graft is one of the best methods for the treatment of the soft tissue defects in the forearms and the hands. This method has advantages of no requirement for a further flap reconstruction, no skin scar or contracture in the future, easy management for the donor site, and less wound formation.
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.
Between 1988 and 1991,27 cases of open fractures of shank bones complicated by soft tissue defect were repaired with fasciocutaneous flaps. The wound surfaces in 11 cases were closed in the first stage and in 16 cases the repair was delayed. The wounds of all the 27 cases had good healing, In fasciocutaneous flaps the blood supply was sufficient and this contributed to subsequent healing. The operation was simple, regardless of the postion of the wound and not damaging the blood vessels. An accurate estimation of the degree of contusion of the soft tissues surrounding the wound was prerequisite to select immediate transposition of fasciocutaneous flapsor delayed transposition.
ObjectiveTo investigate the feasibility of the free descending branch of lateral circumflex femoral artery perforator tissue flap (fascia flap plus skin flap) to repair large soft tissue defects of the extremities and its impact on the donor site. MethodsBetween January 2013 and February 2015, 9 cases of large tissue defects of the extremities were repaired with the free descending branch of lateral circumflex femoral artery perforator tissue flap. There were 8 males and 1 female, aged from 13 to 56 years (median, 36 years). The causes included traffic accident injury in 6 cases and crushing injury by heavy object in 3 cases. Soft tissue defect located at the lower limbs in 7 cases and at the upper limbs in 2 cases, including 2 cases of simple tendon exposure, 2 cases of simple bone exposure, and 5 cases of tendon and bone exposure. After debridement, the soft tissue defect area ranged from 13 cm×7 cm to 20 cm×18 cm. The tissue flaps ranged from 14 cm×8 cm to 23 cm×19 cm. The donor site was directly sutured, scalp graft was used to cover the fascia flap. ResultsAfter operation, partial necrosis of the skin grafting on the fascia flap occurred in 2 cases and healed after dressing change. Arterial crisis occurred in 1 case and the flap survived after anastomosis. The other tissue flaps survived and wounds healed by first intention. The skin grafting healed by first intention in 7 cases, by second intention in 2 cases. The patients were followed up 4-24 months (mean, 10 months). The appearance and function of the tissue flaps were satisfactory, only linear scar was observed at the donor site, which had less damage and no effect on walking. ConclusionFree descending branch of lateral circumflex femoral artery perforator tissue flap can repair large soft tissue defect of the extremities. The donor site can be sutured directly, which reduces damage to donor site and is accord with the principle of plastic surgery.
