[Air pressure vascular clamp. Experimental study and clinical application].

An air pressure vascular clamp was designed for vascular surgery. On femoral arteries of 90 rats, vascular injury and anastomosis experiments were made to compare this clamp with 2 other vascular clamps commonly used, and the pressure on blood vessels from different clamps was determined. Examination with operating, light and electron microscopes showed that the number of vascular injuries and their degree were the least after use of this clamp, the pressure of which could be adjusted just to block blood flow, suitable for blood vessels of different calibers. Satisfactory results have been obtained through its clinical application in 43 patients having 119 vascular anastomoses. It is thought that the unobstructed rate of vascular anastomosis can be raised by the application of this vascular clamp, especially for vessels of small caliber and long period of compression.

Using a Y-shaped vein graft with drain-out branches to provide additional arterial sources for free flap reconstruction in injured lower extremities.

BACKGROUND: Reconstruction of the distal lower extremity with poor arterial circulation is a challenge for reconstructive surgeons, especially when a microsurgical free tissue transfer is necessary. One may face the problem of having no suitable recipient artery to be used except the main one. To overcome this difficult situation, utilization of a Y-shaped vein graft (YVG) was developed. METHODS: We report on 3 successful reconstructions of the lower extremities with free flaps using YVG to supply the arterial inflow and in which the distal circulation of the lower extremity was preserved at the same time. The therapeutic goals, design, surgical technique, and outcomes are clarified. The indications, advantages, and disadvantages are also discussed. RESULTS: All 3 patients achieved successful reconstruction of the affected limbs with uneventful surgery. Special microsurgical skills are unnecessary in this method. It can provide an additional arterial source, which is useful and reliable for revascularizing various kinds of free tissue. Utmost care must be taken to examine the direction of flow during harvesting since only the drainout branches can serve as an ideal YVG. CONCLUSION: We concluded that Y-shaped vein grafting is a good alternative technique to achieve free flap reconstruction of a distal lower extremity with simultaneous preservation of the distal circulation in selected difficult cases.

Emergency free-flap transfer for reconstruction of acute complex extremity wounds.

Nine patients with complex extremity injuries were treated with emergency free-flap transfers over a 3 1/2-year period. The transferred emergency free flaps were performed to cover exposed vital structures. All flaps survived without infection. Complete and careful assessment of the systemic condition of the patient and the nature of the injured extremity is mandatory. Emergency free-flap transfers may salvage the limb or finger and may improve the functional and aesthetic results with the shortest possible hospital stay.

Injuries associated with strenuous road marching.

Injuries were recorded during and up to 12 days after a maximal effort road march. Light infantry soldiers (N = 335) carried a total load of 46 kg over a 20 km course. Twenty-four percent of the soldiers suffered one or more injuries, resulting in 44 days of limited duty. All injuries involved the lower extremities and/or the back. Foot blisters and back problems were the most common complaints (35% and 23%, respectively, of the total injuries). These data indicate that units without recent road marching training can expect a high incidence of injuries as a result of a single demanding road march.

[Repair of anterior tibial, dorsal pedal and calcaneal soft-tissue defects with lateral crural flaps].

OBJECTIVE: To report the methods and clinical effect of the lateral crural flaps in repairing anterior tibial, dorsal and calcaneal soft-tissue defects. METHODS: From August 1999 to December 2004, 18 cases of defects were repaired with lateral crural flap, including 15 cases of anterior tibial, dorsal and calcaneal soft-tissue defects with vascular pedicled island lateral crural flaps and 3 cases of dorsal pedal soft-tissue defects with free vascular lateral crural flaps. RESULTS: All flaps survived after operation. Insufficient arterial supply of the flap occurred in 2 cases after operation, the pedicled incision sewing thread was removed and lidocaine was injected around vascular pedicle, then the flap ischemia was released. Inadequate venous return and venous hyperemia occurred in 1 case because peroneal vein was injured during operation. The flap edge skin was cut and heparin was locally dripped for one week, the flap vascular cycle was resumed. All patients were followed up two months to one year, the flaps were not fat, and the elasticity was good. CONCLUSION: It is safe and reliable to use lateral crural flap to repair anterior tibial, dorsal pedal and calcaneal soft-tissue defects.
