Аннотация
BACKGROUND: Pulmonary thromboembolism (PTE) is a life-threatening condition requiring prompt and effective treatment. Current treatment options include anticoagulation therapy, catheter-directed therapies, and surgical interventions. While inferior vena cava (IVC) filters are widely used for PTE prophylaxis in high-bleeding-risk patients, their failure mechanisms and optimal alternatives remain understudied, particularly in intermediate-high-risk PTE cases where anticoagulation fails.
CASE SUMMARY: We present a case of intermediate-to-high-risk PTE in a 61-year-old woman who experienced recurrent embolization despite receiving anticoagulation therapy. Although an IVC filter was deployed to prevent further embolization, a thrombus from the superficial femoral vein migrated through the tilted IVC filter, and surgical thrombectomy was performed.
DISCUSSION: This case emphasizes the need for careful IVC filter placement to prevent tilt-related complications and supports the adoption of advanced catheter-based thrombectomy devices to enhance the efficacy of PTE treatment and reduce the need for surgical intervention.
