During the past three years, we studied the value of transcutaneous oxygen monitoring in 28 lower extremity vascular bypass procedures. In 21 reconstructions, a rapid rise in the transcutaneous oxygen tension following reperfusion was indicative of a patent graft and patent runoff vessels. Inadequate revascularization was identified in three of four patients in whom transcutaneous oxygen tension failed to rise following femorodistal arterial bypass (positive predictive value 75%). A normal intraoperative transcutaneous oxygen tension study following femorodistal bypass had a negative predictive value of 95%. The overall accuracy was 91%. Transcutaneous oxygen tension monitoring during lower extremity vascular bypass procedures is useful in assessing the success of revascularization and may be used to select which patients should undergo completion arteriography as opposed to those in whom an arteriogram is not essential.
在过去三年中，我们对28例下肢血管搭桥手术中经皮氧监测的价值进行了研究。在21例血管重建术中，再灌注后经皮氧分压迅速升高表明移植血管和流出道血管通畅。在四例股腘动脉搭桥术后经皮氧分压未升高的患者中，有三例发现血管再通不充分（阳性预测值为75%）。股腘动脉搭桥术后术中经皮氧分压研究正常的阴性预测值为95%。总体准确率为91%。下肢血管搭桥手术期间的经皮氧分压监测有助于评估血管再通的成功率，可用于选择哪些患者应进行血管造影，哪些患者则无需进行血管造影。
