| Popis: | This study presents the results of transcutaneous oxygen pressure (TcPO2) monitoring during a treadmill test walk performed in the early stages of peripheral obliterative vascular disease. The study population consisted of a first group of 50 known arteriopathic patients presenting, on questioning, with intermittent claudication; a second group of 50 known arteriopathic patients void of any symptoms of intermittent claudication; and a third group, which was a control cohort of 20 nonarteriopathic, nonclaudicating patients. Though resting TcPO 2 cannot be used to aid the clinical diagnosis of exercise ischemia it may be useful in revealing asymptomatic chronic resting ischemia (9% of cases in this series). On the other hand, a posteffort (recovery phase) fall in TcPO2 had a predictive positive diagnostic accuracy for ischemia on exercise in 99% of the cases reported here versus 87% for clinical appraisal. In the light of these results, TcPO2 measurements coupled to a treadmill test walk perfectly ascertain exercise ischemia in arteriopathic patients, whether asymptomatic or not, and avoid the false-positive results obtained by clinical evaluation. |
