The vascular wall injuries of vena cava inferior and surrounding organs by structural elements of vena cava filters in the late post-implantation period

Abstract

Objective:to study the frequency of vena cava inferior (VCI) injuries by the elements of the modern structures vena cava flters (VCF) and the penetration into surrounding organs and tissues, which revealed during the open surgical interventions for different complications due to the presence of a fltering device in the late post-implantation period.Material and methods:the study had included 31 patient of different age groups, operated for the period from 2008 to 2017 with late complications of implantation of VCF.Results:penetration of structural elements of VCF beyond the limits of VCI was revealed in 20 patients, and 9 of them — in surrounding organs and main vessels. Te age of this group of patients was from 20 to 58 years. Te length of the fltering device in the VCI was from one month to 18 years (Me - 14.5 months). In 95 % of cases, this was the conical models VCF and their parts penetrated the paracaval space. In 5 patients, the elements of the flter device penetrated into the duodenum, 2 in the gonadal veins, and two observations - into the aortic wall and into the liver tissue.Conclusions:damage vascular wall of VCI with elements of the VCF and their penetration into the surrounding organs and tissues in the distant post implantation period is a common complication, in the prevailing part of the observations caused by the implantation of the conical structure VCF.
