背景-我们试图确定经皮氧分压（tcPo（2））测量是否可用于无创检测供应下腹部循环血流的动脉网络中的病变。方法和结果-在疑似（PC，n=43）和非疑似（NPC，n=34）近端缺血的血管患者中进行研究。TcPo 2在两个臀部和胸部参考电极上测量。右侧或左侧动脉造影显示以下一条或多条动脉狭窄（≥ 75%）或闭塞：主动脉、髂总动脉或髂内动脉。将动脉造影与静息时tcPo（2）值（REST）以及活动平板试验期间或之后记录的最小值（MIN）和从静息到最终胸部变化的最大变化（DROP）进行比较。在阳性与阴性动脉造影中，REST、MIN和DROP分别为：80.2 ± 10.9与78.6 ± 11.5（P>0.05），55.2 ± 20.0与69.9 ± 15.8（P <0.05）。
Background-We sought to identify whether transcutaneous oxygen tension (tcPo(2)) measurements could be used to noninvasively detect lesions in the arterial network supplying blood flow to the hypogastric circulation.Methods and Results-A study was undertaken in vascular patients with suspected (PC, n=43) and not with suspected (NPC, n=34) proximal ischemia. TcPo2 was measured on both buttocks and with a chest reference electrode. Arteriography on the right or left side was positive for stenoses (greater than or equal to75%) or occlusion of one or more of the following arteries: the aorta, the common iliac arteries, or the internal iliac arteries. The arteriography was compared with the resting tcPo(2) values (REST) and with the minimal value (MIN) and maximal change from rest normalized to eventual chest changes (DROP) recorded during or after a treadmill test. REST, MIN, and DROP were, respectively, as follows in positive versus negative arteriograms (mean+/-SD; in mm Hg): 80.2+/-10.9 versus 78.6+/-11.5 (P>0.05), 55.2+/-20.0 versus 69.9+/-15.8 (P
