Research on interventional treatment strategies for lower extremity deep venous thrombosis based on real-world data.

Objective: Current treatment strategies for acute lower extremity deep vein thrombosis (DVT) have shifted from merely preventing pulmonary embolism to actively removing thrombus and preserving valve function. However, there is limited evidence comparing the indications and perioperative outcomes of different endovascular strategies. This study aims to investigate the differences in indications, perioperative characteristics, and efficacy trends among three strategies: Angiojet mechanical thrombectomy alone, other thrombus removal devices alone, and a combination of Angiojet with other devices. Methods: A retrospective analysis was conducted on the clinical data of 232 DVT patients who underwent endovascular treatment in the Vascular Surgery Department of our hospital between January 2022 and April 2025. Based on the core thrombus removal method, patients were divided into three groups: Group A (Angiojet alone, Results: There were fundamental differences in thrombus burden among the three groups ( Conclusion: Current endovascular DVT treatment has formed a clear risk-stratified decision-making pathway. Angiojet alone is an efficient and streamlined option for limited acute DVT; for extensive and complex DVT, the intensified strategy of Angiojet combined with other thrombus removal devices has become the standard choice, with its longer operative time and higher rate of vascular interventions reflecting disease complexity. This study provides real-world evidence for individualized endovascular DVT treatment.
