[Evaluation of the revascularization process by staged dynamic transcutaneous oximetry in stage II of obliterative arteriopathy of the lower limbs: a prospective study of 15 patients].
We evaluated the value of dynamic transcutaneous oxygen tension measurement in 15 patients with Leriche stage II intermittent claudication treated with vascular bypass procedures. Fifteen men, median age 60 years (range: 37-72 years), were studied during six months; 19 limbs were revascularized: eight by angioplasty, 11 by patent graft. Claudication perimeter and dynamic transcutaneous oxygen tension measurement were evaluated before and after revascularization. The TcPO2 was continuously measured with a multimodular Kontron Supermon at seven different sites simultaneously: precordium (reference probe), thighs, calves and feet, in the dorsal recumbent position after 30 minutes rest, during a standardized exercise stress test at 50 W and during the recovery phase. The results were expressed as index of surface defect (ISD). After revascularization, the duration of significant ischemia was significantly reduced (P < 0.001 thigh, calf, foot) in 14 patients. Dynamic transcutaneous oximetry therefore seems to be a useful method in assessing stage II occlusive peripheral arterial disease and the topography of tissue hypoxia. Dynamic transcutaneous oximetry is helpful in the surveillance after revascularization and guides the choice of specific treatment (angioplasty or patent graft) especially for multiple lesions.
