Endovascular treatment of post-thrombotic ileocaval-femoral venous obstruction. A case report

According to widely published data, intravascular imaging (IVI)-guided endovascular venous stenting is an effective and safe alternative to open reconstructive surgery of the iliofemoral venous segment. Data on the potential of endovascular treatments for the ileocaval segment are currently insufficient. However, for some patients, this minimally invasive reconstructive surgery may be a viable alternative to open surgery. This article presents the case of a 48-year-old patient with severe postthrombotic disease, severe venous claudication, bilateral ileofemoral obstruction, and extensive occlusion of the infrarenal part of the inferior vena cava. Single-step endovascular IVI-guided recanalization and reconstruction of the ileocaval-femoral segment was performed with implantation of Abre™ and Wallstent™ venous stents. After 6 months, we revealed a decrease in venous hypertension symptoms, an increase in walking distance, a decrease in postthrombotic syndrome severity according to Villalta score, and an improvement in the Venous Clinical Severity Score.
