【Abstract】 Objective To report cl inical experience in the use of temporary intravascular shunts (TIVS) for quickrestoration of perfusion to the extremity with major vascular injury. Methods Between August 2009 and March 2011, TIVSwas applied temporarily to restore blood perfusion to the extremity in 6 patients with major extremity vascular structure injury secondary to trauma (4 patients) or tumor resection (2 patients), who would received vascular transplantation and underwent long ischemia. The patterns of vascular shunts included external carotid artery-subclavian artery, axillary artery-axillary artery, axillary vein-subclavian vein, brachial artery-brachial artery, brachial vein-brachial vein, brachial artery-radial artery, femoral artery-popliteal artery, and popliteal artery-posterior tibial artery. After TIVS, extensive debridement, fracture fixation, or tumor excision was performed. Then the shunted tubes were removed, and the vessels were repaired definitly. Six vessels were repaired by transplanting the great saphenous veins; one vessel was anastomosed directly without tension; and one vessel was repaired by artificial vascular graft. Results All shunted tubes were successfully established within 5 to 10 minutes (mean, 8.2 minutes). The duration of bypass ranged from 67 to 210 minutes. After establishment of TIVS, blood perfusion to the affected limb was improved. When shunted tubes were removed, thrombosis and partial obstruction occurred in one who accepted amputation, and the others kept patency. No loosening of tubes and haemorrhage occurred. At 2-15 months of follow-up, affected limbs had good blood supply. Conclusion TIVS is rapid and simple, which can quickly restore blood perfusion to the extremity with major vascular injury and shorten the ischemic time of the affected extremity.
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. It can provide big area and feel ing recovery by nerve anastomosis. It is an effective method to repair soft tissue defect of the extremities.
To report the diagnosis methods and cl inical treatment effects of blood vessel trunk damage in l imbs. Methods From January 2001 to June 2006, 72 patients with vascular injury in l imbs were treated. There were 50 males and 22 females, aged from 5-60 years (median 39 years) and including 44 cases of open injury and 28 cases of closed injury.The locations were subclavian artery in 1, femoral artery in 23, popl iteal artery in 20, radia artery and ulna artery in 12, brachial artery in 11, axilary artery in 3 and anterior and posterior tibia artery in 2. The disease course was 30 minutes to 27 days. Injured arteries were repaired by suturing directly in 3 cases, by end-end anastomosis in 39 cases and by saphenous transplantation in 30 cases. The length of transplant veins was 3 cm to 8 cm. Results In 72 cases, 67 survived and 5 were given amputation. Fortyeight cases were followed up 6 months to 5 years. The blood flow rate and the diameter of blood vessel on the affected l imbs were not different from that of normal l imbs by colorful Doppler blood flow monitor. Forty cases recovered satisfactory l imb function. Eight cases had different degrees of dysfunction, of them, four cases received functional reconstructive operation, and the function and appearance were improved. Conclusion To investigate the mechanism and situation of injury, to examine patients carefully and analyze comprehensively are the key points of making earl ier diagnosis for branch blood vessel damage; microsurgical repair of the injured blood vessel is the assurance of the blood flow rate. For the blood vessel above elbow and knee injured and lacked blood supply more than 4 hours and fascia syndrome, earl ier opening the fascia cavity is the effective methods to recover the function of the l imbs and to avoid disabil ity.
To summarize the effectiveness of the improv ed surgical techniques in fasciocutaneous flaps of the limbs. MethodsFrom February 1999 to December 2005, 58 patients (39 males, 19 females, aged 1068 years) underwent repairs of the skin defects with improved fasciaocu taneous flaps of the limbs. Twentyone patients had the skin defects in front of the tibial bone in the middle and lower parts, 12 patients had the skin defect s in the heels, 16 patients had the skin defects in the ankles, 3 patients had t he skin defects around the knees, 1 patient had a wide sacrococcygeal bedsore, and 5 patients had the skin defects in the wrists and hands. The wounds ranged in size from 5 cm×3 cm to 18 cm× 12 cm. According to the wound lo cations, the following flaps were selected: 4 cutaneous antebrachii medialis nerve and basilic vein fasciocutaneous flaps, 1 cutaneous antebrachii lateralis nerve and cephalic vein fasciocutaneous flap, 3 saphenous nerve and great saphenousvein fasciocutaneous flaps, 1 cutaneous nerve of thigh posterior fasciocutaneous flap, 32 reverse sural nerve and saphenous vein fasciocutaneous flaps, and 17 reverse saphenous nerve and great saphenous vein fasciocutaneous flaps. The dissected flaps ranged in size from 6 cm× 4 cm to 18 cm× 13 cm. The donor wounds underwent straight sutures in 39 patients, and the skin grafting (6 cm×3 cm to 13 cm× 6 cm) was performed on 19 patients after the donor wounds were closed. Results The wounds healed by first intention, and the flaps survived completely in 54 patients. The flaps developed partial necrosis in 4 patients. The followup for 120 months (average, 8 months) revealed that the flaps had a satisfactory appearance with a soft texture and the function was also satisfactory. Conclusion A fasciocutaneous flap of the limbs is an ideal flap for repairing defects in the skins and soft tissues of the limbs. The survival rate of the flap can be further improved by an improvement of the surgical techniques.
Objective To investigate the application and effect of the crossbridge vascular anastomosis free flap transplantation for tissue defects of extremities. Methods From May 1982 to November 2005, 110 cases of tissue defects of extremities were treated with cross-bridgevascular anastomosis free tissue transplantation. Of 110 patitents, 80 were male and 30 were female with a median age of 30 years(5 to 54 years). Tissue defects were caused by traffic accidents (59 cases), machine injuries (32 cases) and mangled injuries (19 cases). The locations were the forearms in 2 cases and the legs in 108 cases. And 69 cases had simple soft tissue defects, 6 cases had simple bone defects, and 35 cases had complicated defects. The length of bone defectranged from 5 cm to 19 cm and the area of soft tissue defect ranged from 6 cm×10 cm to 15 cm×35 cm. The graft tissue included latissimus dorsi musculocutaneous flap, vastus anterolateral flap,cutaneous fibula flap, osseous fibula flap, and cutaneous iliac flap. The cross-bridge of the two lower extremities wasperformed in 106 cases, the cross-bridge of the two upper extremities in 2 cass, and the crossbridge of the upper-lower extremities in 2 cases. The compoite tissue transplantation was used if the graft tissues were two or more. The wounds of donor site was directly sutured in 67 cases, and partly sutured with skingrafting in 43 cases. Results Vascular crisis occurred in 9 cases. Vascular crisis was relieved in 5 cases and grafting tissues was survival after exploring the vessel; 4 cases failed. The graft tissue was survival in 101 cases, and the survivalrate was 96.4%. The follow-up time was 4 months to 22 years with an average of 6.3 years. Graft bone healed and mean healing time was 4 months. The flap appearance was satisfactory and extremity function was restored to normal. One case became necrosis in the edge of the flap and cured by debridement, dressing and skingrafting, the other got primary healing at 2-3 weeks after operation. Conclusion The application of the cross-bridge vascular anastomosis free tissue transplantation for tissue defects of extremities is an effective method, when extremities have no vessel anastomosed.
