INTERVENTIONAL METHODS FOR THE PREVENTIONOF COMPLICATIONS AFTER ENDOVASCULAR PROSTHETICSOF INFRARENAL AORTIC ANEURYSM: LITERATURE REVIEW

Abstract

Introduction. The Republic of Kazakhstan has currently accumulated quite a lot of experience in performing
endovascular interventions in patients with aneurysmal lesions of the infrarenal aorta. In the course of evaluating the longterm results of endovascular prosthetics, carried out in the framework of a number of scientific works, it was found that the
most common complication that worsens the results of endovascular treatment of aneurysms is the development of
endoleaks into the cavity of the aneurysmal sac after its isolation. Currently used methods of preventive embolization using
metal coils and endovascular occluders show a high incidence of retrograde endoleaks and the development of high
intermittent claudication (5.53% and 29.5%, respectively).
Purpose: Study the results of using interventional methods to prevent endoleaks after endovascular repair of infrarenal
aortic aneurysms according to the literature.
Search strategy. During a literary search in Russian and English with a depth of 20 years (2002-2022) in databases and
web resources PubMed (MEDLINE), eLIBRARY, Google Scholar, CyberLeninka (CYBERLENINKA) using the keywords:
"EVAR", " Endoleak, EVPBA, endoleak, 347 literature sources were found, from which 67 were selected that met the
inclusion criteria: reports on randomized and cohort studies, systematic reviews and meta-analyses, diagnostic and
treatment protocols. Exclusion criteria: newspaper publications, descriptions of clinical cases, abstracts, personal messages,
as well as sources containing duplication or repetition of information. In some cases, links are given to earlier publications
that have historical value in the issue under study.
Results. The review material describes the early and long-term results of endovascular repair of infrarenal aneurysms,
outlines the most common complications that worsen the results of treatment. The dynamics of changes in the results of
surgical interventions with the accumulation of experience and the development of new generations of endovascular devices
is reflected.
Conclusions. When studying the long-term results of endovascular prosthetics and open reconstructive interventions,
no difference in survival was found. In this regard, one of the main tasks facing a modern vascular and endovascular
surgeon in the surgical treatment of infrarenal aneurysms is the development and application of measures to prevent
possible complications, which, ultimately, will improve the results of treatment of this category of patients. The issue of
prevention and control of complications of endovascular prosthesis considered in this article showed insufficient development
of the topic in terms of improving the results of surgical interventions.
