Dynamics of transcutaneous oxygen tension at the operations on the aorto-femoral segment distal of the level of aortic compression

Abstract

Estimation of transcutaneous partial pressure of oxygen is the main noninvasive method of evaluation and study microhaemodynamics and tissue blood supply. Aim of the research: to study the dynamics of transcutaneous partial pressure of oxygen at surgery of aortofemoral segment performed more distally of aortic compression. Material and methods: the survey included 49 patients with arterial sclerotic disease of aortofemoral segment with comorbid Ilb-IV stage chronic lower limb ischemia according to Pokrovsky-Fountain classification, and with II-III stage chronic infrarenal abdominal aortic aneurysm according to Pokrovsky classification. The patients' age was 52-76y.o. For the assessment of peripheral microhaemodynamics we used the technique of estimation of transcutaneous partial pressure of oxygen (ТсРО2) with application of multichannel monitor of Radiometer TCM-400 system. The suggested method offers the possibility to evaluate the severity degree of microcirculatory disorders in lower limbs and to assess effectiveness of revascularization process.
