Investigation of Venous Thromboembolic Complications in Patients Undergoing Endovascular Intervention

Abstract

Introduction: Venous thromboembolic complications (VTC) have been an important public health issue for many years. Venous thromboembolic complications include deep vein thrombosis of the lower extremities, saphenous vein thrombosis and pulmonary embolism. Endovascular surgeries are considered to be minimally traumatic, medium-long and complex surgical interventions, with catheterization or other intravascular manipulations. Therefore, deep vein thrombosis and pulmonary embolism are also possible after these surgeries. This potential risk is related both to possible stasis and endothelial damage during catheterization or o  ther intravascular manipulations and to risk factors.

Objectives: Aim of the study: to study the incidence of VTC during endovascular interventions.

Methods: The research was conducted in the period from June to October 2022, 115 case histories of patients admitted to the Federal Center for Brain and Neurotechnology in Moscow were analysed during this period. Ultrasound duplex scanning was performed in all patients in the postoperative period.

Results: No clinical signs of lower limb venous thrombosis were found during postoperative period examination. Analysis of the results of ultrasound duplex scanning showed the presence of VTC in 5 patients (4.3±1.9%). One patient had echo-signs of thrombosis with recanalization, four patients had echo-signs of "fresh" thrombosis.

Conclusions: Screening ultrasound duplex scanning of lower limb vessels as the most objective method of VTC diagnosis should be performed in all patients without exception in the first day after the operation, since clinical signs of VTC may be absent or non-specific.
