OBJECTIVETo explore the therapeutic strategy of hot press injury complicating with blood vessel injury in the upper extremity.
METHODSDecompression procedure was carried out in 8 patients with hot press injury complicating with blood vessel injury in the upper extremities, but the effect was not of satisfactory because there were injuries to brachial, radial and ulnar arteries and also injury to the superficial or deep palmar arch. The blood vessels were repaired with direct anastomosis, anastomosis with flexion of the limb, or transplantation with great saphenous vein, and the wounds were covered with intermediate split-thickness skin graft or pedicled thoraco-abdominal skin flap.
RESULTSOne patient with repair of the brachial artery and intermediate split thickness skin graft received amputation 4 weeks after operation because of lack of soft tissue coverage. The blood supply recovered completely in the other patients, so the affected limbs were saved.
CONCLUSIONPrompt exploration and repair of blood vessel, and coverage of the wound with healthy soft tissue are key procedures for the management of hot press injury complicating with blood vessel injury in the upper extremities.

OBJECTIVE:
To evaluate the effectiveness of neurovascular staghorn flap for repairing defects in fingertips.
METHODS:
Between August 2019 and October 2021, a total of 15 fingertips defects were repaired with neurovascular staghorn flap. There were 8 males and 7 females with an average age of 44 years (range, 28-65 years). The causes of injury included 8 cases of machine crush injury, 4 cases of heavy object crush injury, and 3 cases of cutting injury. There were 1 case of thumb, 5 cases of index finger, 6 cases of middle finger, 2 cases of ring finger, and 1 case of little finger. There were 12 cases in emergency, and 3 cases with finger tip necrosis after trauma suture. Bone and tendon exposed in all cases. The range of fingertip defect was 1.2 cm×0.8 cm to 1.8 cm×1.5 cm, and the range of skin flap was 2.0 cm×1.5 cm to 2.5 cm×2.0 cm. The donor site was sutured directly.
RESULTS:
All flaps survived without infection or necrosis, and the incisions healed by first intention. All patients were followed up 6-12 months, with an average of 10 months. At last follow-up, the appearance of the flap was satisfactory, the wear resistance was good, the color was similar to the skin of the finger pulp, and there was no swelling; the two-point discrimination of the flap was 3-5 mm. One patient had linear scar contracture on the palmar side with slight limitation of flexion and extension, which had little effect on the function; the other patients had no obvious scar contracture, good flexion and extension of the fingers, and no dysfunction. The finger function was evaluated according to the total range of motion (TAM) system of the Hand Surgery Society of Chinese Medical Association, and excellent results were obtained in 13 cases and good results in 2 cases.
CONCLUSION
The neurovascular staghorn flap is a simple and reliable method to repair fingertip defect. The flap has a good fit with the wound without wasting skin. The appearance and function of the finger are satisfactory after operation.

OBJECTIVE:
To investigate the clinical application of high-frequency color Doppler ultrasound (HFCDU) in detecting perforators in the deep adipose layers for harvesting super-thin anterolateral thigh flap (ALTF).
METHODS:
Between August 2019 and January 2023, 45 patients (46 sides) with skin and soft tissue defects in the foot and ankle were treated, including 29 males and 16 females, aged from 22 to 62 years, with an average of 46.7 years. The body mass index ranged from 19.6 to 36.2 kg/m 2, with an average of 23.62 kg/m 2. The causes of injury included traffic accident injury in 15 cases, heavy object crush injury in 20 cases, mechanical injury in 8 cases, heat crush injury in 1 case, and chronic infection in 1 case. There were 20 cases on the left side, 24 cases on the right side, and 1 case on both sides. After thorough debridement, the wound size ranged from 5 cm×4 cm to 17 cm×11 cm. All patients underwent free super-thin ALTF transplantation repair. HFCDU was used to detect the location of the perforators piercing the deep and superficial fascia, as well as the direction and branches of the perforators within the deep adipose layers before operation. According to the preoperative HFCDU findings, the dimensions of the super-thin ALTF ranged from 6 cm×4 cm to 18 cm×12 cm. The donor sites of the flaps were directly sutured.
RESULTS:
A total of 55 perforators were detected by HFCDU before operation, but 1 was not found during operation. During operation, a total of 56 perforators were found, and 2 perforators were not detected by HFCDU. The positive predictive value of HFCDU for identifying perforator vessels was 98.2%, and the sensitivity was 96.4%. Among the 54 perforators accurately located by HFCDU, the orientation of the perforators in the deep adipose layers was confirmed during operation. There were 21 perforators (38.9%) traveled laterally and inferiorly, 12 (22.2%) traveled medially and inferiorly, 14 (25.9%) traveled laterally and superiorly, 5 (9.3%) traveled medially and superiorly, and 2 (3.7%) ran almost vertically to the body surface. Among the 54 perforators accurately located by HFCDU, 35 were identified as type 1 perforators and 12 as type 2 perforators (HFCDU misidentified 7 type 2 perforators as type 1 perforators). The sensitivity of HFCDU in identifying type 1 perforators was 100%, with a positive predictive value of 83.3%. For type 2 perforators, the sensitivity was 63.2%, and the positive predictive value was 100%. The surgeries were successfully completed. The super-thin ALTF had a thickness ranging from 2 to 6 mm, with an average of 3.56 mm. All super-thin ALTF survived, however, 1 flap experienced a venous crisis at 1 day after operation, but it survived after emergency exploration and re-anastomosis of the veins; 1 flap developed venous crisis at 3 days after operation but survived after bleeding with several small incisions; 3 flaps had necrosis at the distal edge of the epidermis, which healed after undergoing dressing changes. All 45 patients were followed up 6-18 months (mean, 13.6 months). Three flaps required secondary defatting procedures, while the rest had the appropriate thickness, and the overall appearance was satisfactory.
CONCLUSION
Preoperative application of HFCDU to detect the perforator in the deep adipose layers can improve the success and safety of the procedure by facilitating the harvest of super-thin ALTF.

OBJECTIVETo retrospectively analysis the treatment characteristics of the systemic situation in patients with crush syndrome after Wenchuan earthquake happened in May 12th, 2008.
METHODSForty-nine patients with crush syndrome and subsequent acute renal failure (ARF) due to the earthquake were treated in West China Hospital. All of patients had been rescued from buildings that collapsed in Wenchuan earthquake. The major associated injuries were in the low extremities and upper extremities. 49 patients developed ARF with increased concentrations of serum creatinine (mean 64 022 U/L) had underwent haemodialysis. Hyperkalaemia was seen in 9 patients and four of them underwent haemodialysis. 49 patients were administered hemodialysis.
RESULTSNo patient died. All patients who suffered from the ARF were weaned from hemodialysis after admitted 7 to 35 days. Forty-five extremities underwent amputations and 52 extremities had fasciotomy.
CONCLUSIONSCrush syndrome requires urgent recognition and prompt surgical treatment with simultaneous measures to control hyperkalemia and ARF. The authors believe that immediate intensive care therapy and multi-subjective coordination would have improved the survival rate.
