Bilateral catheter-directed thrombolysis in a patient with deep venous thrombosis caused by a hypoplastic inferior vena cava.

INTRODUCTION: Deep venous thrombosis treatment using catheter-directed thrombolysis is advocated over systemic thrombolysis because it reduces bleeding complications. With the development of a catheter that combines ultrasound vibrations and the local delivering of thrombolytics, new and safer treatments appear that are suitable for more complex problems.

REPORT: An adolescent male presented with bilateral iliofemoral thrombosis based on a hypoplastic inferior vena cava that had existed for more than two weeks. He was successfully treated by bilateral ultrasound-accelerated catheter-directed thrombolysis using EkoSonic® (Small Vessel) Endovascular System (EKOS) and stenting of the inferior vena cava. After eight months of follow-up, the inferior vena cava is still patent.

CONCLUSION: EKOS thrombolysis of longer existing bilateral deep venous thrombosis in the central venous system is a successful treatment modality in congenital inferior vena cava anomalies.
