POTENTIAL AND PERSPECTIVES OF INDIRECT REVASCULARIZATION IN TREATMENT OF LOWER LIMBS CRITICAL ISCHEMIA

Abstract

This review was undertaken by a literature search of the International scientific database PubMed and Cochrane library. The review highlights the issues and perspectives of indirect revascularization in the patients with lower limbs critical ischemia. The study revealedthat lower limbs critical ischemia remains the actual problem ofangiosurgery, despite of the widespread introduction of angioplasty and open vascular reconstruction. However, angioplasty and bypass surgery revascularization cannot be performed in some category of patients, so that the further improvement of indirect revascularization techniques has been of great interesttoresearchers. The severity of the ischemic process is determined not only by the mechanical blood flow restriction but also by the angiogenic potential of the surrounding soft tissues, foremost muscular one. Therefore, in the case of technical irreparability of the main blood flow it remains possible to preserve the limb by creating new vascular networks in the muscular tissue. Revascularizing osteotrepanation of the lower limb bones is considered to be theoptimal variant to achieve this result. The discontent of clinical outcomes occurred due to the slow development of the angiogenic effect, which in critical ischemia is fraught with loss of a limb until the maximal angiogenesis is reached. In recent years, cell therapyhas become a very promising and advanced scientific research topic. So that its methods have been actively introduced into practice; they are easily combined with revascularizing osteotrepanation and are able significantly accelerate angiogenesis induced by surgical bone injury. In this regard, there is reason to believe that curative effect increases when revascularising osteotrepanation is combined with cell therapy, including the use of bone marrow aspirates.
