Twelve canine rib transposition grafts were harvested and evaluated for preservation of subperiosteal and medullary canal blood flow using the hydrogen washout technique. Blood flow using hydrogen washout technique also was studied in the T11 vertebral body. The mean hydrogen washout blood flow was 0.201 ml/min/ml tissue for the subperiosteal rib measurement, 0.058 ml/min/ml tissue for a rib medullary measurement, and 0.085 ml/min/ml tissue for the vertebral body. The medullary canal hydrogen washout values were consistently less than the subperiosteal values. The results have demonstrated that the blood supply to the vascularized rib pedicle can be retained and quantitated in harvesting the rib graft using the hydrogen washout technique.
采集了12个犬肋骨转位移植物，并使用氢洗脱技术评估骨膜下和髓腔血流的保留情况。还在T11椎体中使用氢洗脱技术研究了血流。骨膜下肋骨测量的平均氢洗脱血流为0.201 ml/min/ml组织，肋骨髓腔测量为0.058 ml/min/ml组织，椎体为0.085 ml/min/ml组织。髓腔氢洗脱值始终低于骨膜下值。结果表明，在使用氢洗脱技术采集肋骨移植物时，可以保留并定量带血管蒂肋骨的血供。
