The "gold standard" for amputation level selection" xenon-133 clearance.

摘要: Abstract Numerous noninvasive testing modalities for prospective lower-extremity amputation level selection have been reported and include Doppler ultrasound pressure measurements, thermography, calf muscle pH, radioisotope skin perfusion pressures, pulse volume recording. Although each of these techniques has improved the accuracy selection, compared to indirect perimeters such as assessment bleeding at surgery, none test provides a clear-cut objective endpoint. This report describes our experience with determination blood flow by xenon-133 clearance selection. Between July 1, 1977, April 1980, 137 amputations were performed in 102 patients. Preoperative xenon determinations available 76 amputations. Amputation levels included 6 toe, 9 transmetatarsal, 13 Symes, 36 belowknee, 7 knee disarticulation, 4 above-knee, 1 hip disarticulation. In rates exceeding 2.2 ml/100 g tissue/min 70 74 (95%) healed primarily. Four healing failures due errors surgical judgement (two) late stump trauma (two). Our data suggest that provide accurate information all amputation. addition, utilization this type technique remarkably high incidence conservative including
