[Venous stenting in acute period of total and subtotal deep vein thrombosis].

OBJECTIVE

To study the efficacy and safety of venous stenting and long-term anticoagulation with inhibitors of blood clotting factor XA in the treatment of total and subtotal deep vein thrombosis.

MATERIAL AND METHODS

We analyzed 60 patients with total and subtotal deep vein thrombosis divided into 2 comparable groups by 30 people. Patients of the first group underwent regional catheter thrombolysis and percutaneous mechanical thrombectomy. The same endovascular treatment supplemented by venous stenting was performed in the second group. In the first group, rivaroxaban was prescribed before, during and for 6 months after surgery; apixaban was used in the second group. Complications of endovascular and anticoagulant therapy were recorded. After 12 months, control ultrasound and clinical examination of patients was performed to analyze recanalization of deep veins and severity of venous outflow disorders. Recanalization of veins was evaluated as follows: less than 50% - minimal, 50-99% - partial, 100% - complete.

RESULTS

In the first group, complete and partial recanalization of veins was found in 63.3 and 36.7% of patients, respectively. In the second group, these values were 93.3 and 6.7%, respectively. In the first group, venous outflow disorders were absent in 56.7%, mild violations presented in 36.6%, moderate violations - in 6.7% of patients. In the second group, venous outflow was normal in 93.3% of patients, and mild disorders presented in 6.7% of patients. Hemorrhagic complications developed in 8 (13.3%) patients, equally in both groups.
