Indirect revascularization in patients, suffering critical ischemia of the lower extremities on background of diabetes mellitus

Abstract

Objective. Determination of clinical efficacy of the mesenchymal stem cells transplantation in patients, suffering critical ischemia of the lower extremities on background of diabetes mellitus. Materials and methods. There were examined 11 patients, suffering critical ischemia of the lower extremities on background of diabetes mellitus Type II with purulent-necrotic processes of the foot, in whom conditions for the direct revascularization of extremity were absent. Microbiological monitoring for the wound discharge, determination of the ankle brachial index and transcutaneous oximetry was performed. The technology elaborated have consisted of two stages. On the first of them a purulent focus sanation (in all the patients the distal amputations of the foot, preserving arterial arch) was done. On the second stage the therapy of the wounds was conducted, using negative pressure, injections of cellular suspension (mesenchymal stem cells) while applying long fine cannula under aponeurosis into the muscles along obliterated vessels in the (10 ± 5) ml quantity with subsequent closure of the wound surface, using fibroblastic matrix. Results. In a year after the treatment critical ischemia in 1 patient was noted, the ischemia Grade III - in 3, and in 7 a IIB Grade have persisted. Conclusion. Performance of indirect revascularization, using autologous mesenchymal stem cells, constitutes an effective and secure procedure.
