The Effectiveness of Xeno-Pericardial Patch in Revascularization of an Ischemic Limb Using the Deep Femoral Artery

Abstract

HighlightsThe choice of method for revascularization of the ischemic lower limb remains an important issue in cardiovascular surgery. Of the available methods, the most effective, in our opinion, is revascularization of the limb using the deep femoral artery. In this case, it is necessary to carefully select the material for the expanding patch, which prevents the development of restenosis. AbstractAim. To compare the effectiveness of autovenous and xeno-pericardial patches in revascularization of an ischemic limb using a deep femoral artery.Methods. An analysis of the comprehensive examination and treatment of 30 patients with critical ischemia, who were divided into 2 statistically homogeneous groups of 15 people each, was carried out. In the first group, an autovenous patch was used to repair the deep femoral artery, and in the second group, a xeno-pericardial patch was used. The short-term results of treatment were assessed by the number of postoperative complications, ankle brachial index and the clinical picture of the disease 1 month after surgery, whereas the long-term results were assessed by the deep femoral artery patency and the quality of life of patients.Results. 6 complications of the same type were registered in 4 (13.3%) patients, two in each group. After 1 month, the ankle brachial index in the first group was 0.58±0.12, and in the second 0.61±0.13. All patients in both groups had relief of pain at rest, an increase in pain-free walking distance, and trophic disorders healed. After 5 years, the deep femoral artery in the first group remained passable in 11 (73,3%) patients, and in the second – in 15 (100%) patients. The physical component of the health of patients in the first group scored 41.7±3.4, in the second group – 48.6±3.4, and the psychological component of health scored 52.1±3.9 and 56.9±3.6, respectively.Conclusion. Xeno-pericardial patches proved to be more effective in revascularization of an ischemic limb using a deep femoral artery compared with autovenous patches in the long-term postoperative period.
