A Non-Invasive Evaluation on Perfusion in Patients with Foot Wounds and the Effect of Non-Invasive Measurements on Determination of Treatment Methods

Abstract

Foot wounds are one of the most important reasons that prolong hospitalization and treatment period of patients. Different invasive and noninvasive diagnostic methods are used for preoperative evaluation. TcpO2(Transcutaneous oxygen measurements) that is noninvasive method, and evaluate tissue oxygenation on treatment planning in addition to conventional methods.The aim of study was to evaluate the effect of TcpO2 measurements on preoperative foot perfusion, planning medical treatment and amputation level. Seventeen patients who had foot ulcer admitted to our clinic between 01/2015 and 06/2018 were included in the study. TcPO2 were performed percutaneously measured from different arterial segments.The measurements were first measured in the supine position and then the foot was taken 45 degrees and then measured and recorded. The TcpO2 values decreased to more than 10% was considered significant.The number of cases in which the TcpO2 value decreased by more than 10% was 12(70.6%). Five patients(29.4%) underwent medical treatment, 5 patients(29.4%) underwent surgical vascularization and 7 patients(41.2%) underwent amputation. TcpO2 values decreased to more than 10% in the end arteries of all patients who underwent amputation. We believe that TcpO2 measurement method may be helpful in the determination of angiography planning, revascularization necessity, medical treatment and amputation level.
