[Endovascular treatment of deep vein thrombosis of the upper extremities]. / Endovaskulyarnoe lechenie trombozov glubokikh ven verkhnikh konechnostei.

OBJECTIVE: To improve the results of treatment of deep vein thrombosis of the upper extremities sing endovascular technologies. MATERIAL AND METHODS: We analyzed safety and effectiveness of treatment in 24 patients with deep vein thrombosis of the upper extremities. All ones were divided into 2 homogeneous groups by 12 people each. In the first group, conventional anticoagulation was performed. In the second group, we used additional regional catheter thrombolysis with alteplase and, if necessary, venous stenting or balloon angioplasty for residual stenosis. Patients received apixaban at baseline and throughout 6 postoperative months. After 12 months, we performed ultrasound and clinical examination to identify deep vein patency and venous outflow disorders. Vein recanalization was evaluated as follows: <50% - minimal, 50-99% - partial, 100% - complete. The quality of life of patients was studied using the SF-36 questionnaire. RESULTS: In the first group, we observed complete vein recanalization in 25% of cases, partial - in 33%, minimal - in 41% of cases; in the second group - 83.3% and 16.7% of patients, respectively. In the first group, clinical manifestations of venous outflow disorders were absent in 25% of patients, mild disorders - 25%, moderate - 8.3%, severe - 41.7% of patients. In the second group, venous outflow was not impaired in 83.7% of patients, mild violations occurred in 16.7% of patients. In the first group, physical health was equal to 44.2±1.7 scores, psychological health - 49.3±2.3 scores; in the second group - 69.3±5.7 and 71.3±5.4 scores, respectively. CONCLUSION: Endovascular treatment improved postoperative outcomes.

OBJECTIVE: To improve treatment outcomes in patients with late stages of total-subtotal deep vein thrombosis using pharmacomechanical thrombectomy. MATERIAL AND METHODS: We compared treatment outcomes in 2 homogeneous groups of patients with deep vein thrombosis and severe acute venous insufficiency. Standard anticoagulation (apixaban) was performed in the first group (n=20), endovascular treatment was applied in the second group (n=20). Regional catheter thrombolysis was performed at the first stage, and percutaneous mechanical thrombectomy was performed at the second stage. Incidence of hemorrhagic syndrome was assessed. The results were evaluated after one year considering patency of deep veins and severity of venous outflow disorders. RESULTS: Hemorrhagic complications occurred in 15% and 25% of patients, respectively. This required discontinuation of anticoagulation throughout the treatment and subsequent appointment of minimum doses of apixaban. Complete restoration of vein patency was observed in 20% and 55%, partial recanalization - 45% and 25%, minimal recovery - in 35% and 20% of patients, respectively. In the first group, venous outflow disorders were absent in 20% of patients, mild disorders were registered in 45%, moderate - 20%, severe - 15% of patients. In the second group, these values were 55%, 25%, 20% and 0% of patients, respectively. CONCLUSION: Pharmacomechanical thromboectomy can improve treatment outcomes.

The authors reviewed national and world literature data on endovascular technologies for the treatment of deep vein thrombosis. Indications, technologies, complications and results of systemic and regional thrombolysis are described in detail. The authors consider percutaneous mechanical thrombectomy, pharmacomechanical thrombectomy, venous stenting and catheter thrombectomy. The role of combined endovascular approaches in delayed stages of disease is emphasized. The indications for implantation of cava filter are presented.
