  • CLINICAL APPLICATION OF FREE SKIN GRAFT WITH SUBCUTANEOUS FAT

    Twenty cases with skin defect of forearm and hand were treated by free skin graft with subcutaneous fat from 0.5 to 0.7 cm in thickness. The maximal area of free skin graft is 27×10cm, and the smallest one is 1.5×2cm. All of skin flaps survived except one having partial necrosis. Follow up shown round external figure, clasticity, and no change of skin color. It preserved the function of sweat gland and the cutaneous sensation began to recover 4 months postoperation.

  • THE PROBLEMS IN THE USE OF SUPERFICIAL CERVICAL ARTERY SKIN FLAP AND IT’S RELEVANT SOLUTION

    Superficial cervical artery skin flap is widely used in clinical practice. In order to inprove the outcome of the flap in clinic, eleven cases of skin defect of scalp who were treated with the flap was discussed. After operation, the donor area healed but there was no hair growth on recipient area. Among them, six cases occurred partial necrosis of skin flaps. In order to avoid these problen, the relevant solution discussed as follows: 1. Handle well the pedicle of the skin flap to prevent the interference with venous returm. 2. Adhere strictly to indications. 3. Apply skin expander to obtain "extra" skin, then carryout the tranfer of skin flap and 4. Better use the skin flap with residual hair.

  • NARROW PEDICLED INTERCOSTAL CUTANEOUS PERFORATOR THIN FLAP FOR COVERAGE OF SKIN DEFECT OF HAND

    Abstract The narrow pedicled intercostal cutaneous perforater (np-ICP) thin flaps were successfully used for reconstruction of hand deformity from scar contraction. This flap was designed with a narrow pedicle (3~5cm in width) which included ICPs of 4th~9th intercostal spaces, and with awide distal part (the maximum is 15cm×15cm) which covered the lower chest and upper abdomen. The thickness of flap was cut until the subdermal vascular networkwas observed. The pedicle was divided between the 7th~14th days after operation. Sixteen flaps in 15 cases were transferred for covering of the skin defects at the dorsum of the hand. The perforators which were included in the narrow pediclewere mostly from the 7th intercostal spaces in 9 flaps. Fifteen of the 16 flapswere survived almost completely, except in one case there was necrosis of the distal portion of the flap. It seemed that this flap was more useful than the conventional methods, not only functionally but also aesthetically. Moreover, the operative techinque was more simple and safer than the island or free intercostalflap due to without the necessity to dissect the main trunk of the intercostalneurovascular bundle. Gentle pressure on the thinning portion of the flap for a short time after operation was important.

  • REPAIR OF HUGE SKIN DEFECT ON LEG AND FOOT WITH MULTIPLE PEDICLED BLOCKING RANDOMIZED FASCIOCUTANEOUS FLAP

    OBJECTIVE In order to increase the survival area of pedicled fasciocutaneous flap, a multiple pedicled blocking randomized fasciocutaneous flap was designed. METHODS From January 1991 to September 1998, this technique was used to repair 33 cases, including 27 males and 6 females and the ages ranged from 6 to 58 years. All of the patients were suffered from traffic accidents. In these cases, 22 cases had skin defects of legs and feet with bone, nerve and tendon exposed, 5 cases had osteomyelitis as well as internal fixaters exposed and the other 6 had deformity from scar. The size of the flap was 25.0 cm x 13.0 cm x 2.4 cm at its maximum and 6.0 cm x 3.5 cm x 1.5 cm at its minimum. Based on the traditional blocking flap, according to the severity of the wound and conditions of the neighboring tissues, a flap having 2 to 4 orthogonal pedicles with a width of 1.5 to 3.0 cm was designed. The medical-graded stainless steel sheet was implanted below the deep fascia, and after blocking for 3 to 6 days, the side pedicles were divided. 6 to 14 days later, one of the two remaining pedicles was divided and was transferred to repair the defect. RESULTS 31 cases were followed up for 6 months to 5 years without any trouble of the joints. The flap had a good external appearance and was high pressure-resistant. CONCLUSION The multiple pedicled blocking randomized fasciocutaneous flap increased the size of the flap and the length to width ratio. It had the following advantages: manage at will, high resistance to infection and a large survival area of flap.

  • MICROSURGERY TREATMENT OF OLD ACHILLES TENDON RUPTURE MERGING WITH SKIN DEFECT

    OBJECTIVE: To explore the methods of treatment for old achilles tendon rupture merging with skin defect. METHODS: By following up retrospectively 10 patients from February 1995 to December 2001, we analyzed the operative methods, the points for attention and the results. Gastrocnemius musculocutaneous flaps were used in 3 cases, foot lateral skin flaps in 4 cases, superior medial malleolus skin flaps in 2 cases, and sural neural skin flap in 1 case. The Achilles tendon was sutured directly in 8 patients, with Lindholm’s technique in 2 patients. RESULTS: All flaps survived and the wound healed well in 8 cases and reruptured in 2 cases. According to Yin Qing-shui’s criteria to test the efficacy, the results were excellent in 5 patients, good in 4 and poor in 1. CONCLUSION: Repairing the old Achilles tendon rupture merging with skin defect by use of microsurgery has good results and plays an important role in reducing joint contracture and stiffness, and in saving the ability to push forward and flex.

  • EFFECT OF HUMAN PLACENTAL DECIDUA BASALIS DERIVED MESENCHYMAL STEM CELLS IN REPAIR OF NUDE MICE SKIN WOUND

    ObjectiveTo investigate the effectiveness of human placental decidua basalis derived mesenchymal stem cells (PDB-MSCs) in repairing full-thickness skin defect of nude mice. MethodsHuman placenta samples were obtained from healthy donor mothers with written informed consent. PDB-MSCs were isolated through enzymic digestion and density gradient centrifugation; the 4th passage cells were identified by cellular morphology, cell adipogenic and osteogenic differentiation, and phenotype evaluation. Forty-two 4-5-week-old BALB/c female nude mice were randomly divided into experimental group (n=21) and control group (n=21). The 4th passage PDB-MSCs solution (200 μL, 5×106/mL) was injected into the mice of experimental group via caudal vein; the mice of control group were given equal volume of PBS. The full-thickness skin defect model of 1.5 cm×1.5 cm in size was made after 3 days. The wound healing was observed generally at 1, 2, 4, 7, 14, 18, 21, 25, and 30 days after operation, and the wound healing rate was calculated after wound decrustation. HE staining was used to observe the wound repair at 1, 7, 14, 21, and 31 days; immunofluorescent staining was used for cellular localization at 7, 14, and 31 days after operation. ResultsCells isolated from human placenta were MSCs which had multipotential differentiation ability and expressed MSCs phenotype. Animals survived to the end of the experiment. The general observation showed that the experimental group had a faster skin repairing speed than the control group; the time for decrustation was 12-14 days in experimental group and was 14-17 days after operation in the control group. The wound healing rate of experimental group was significantly higher than that of control group at 14, 18, and 21 days (t=4.001, P=0.016; t=3.380, P=0.028; t=3.888, P=0.018), but no significance was found at 25 and 30 days (t=1.565, P=0.193; t=1.000, P=0.423). HE staining showed lower inflammatory reaction, and better regeneration of the whole skin and glands with time in the experimental group. The immunofluorescent staining was positive in skin defect area of experimental group at different time points which displayed that human PDB-MSCs existed. ConclusionThrough enzymic digestion and density gradient centrifugation, PDB-MSCs can be obtained. Pre-stored PDB-MSCs can mobilize to the defect area and participate in repair of nude mice skin.
