Insights
Acute aortofemoral graft occlusion can be treated with endovascular therapy. A case study shows the Trellis thrombectomy-thrombolysis system successfully cleared the occlusion, avoiding surgical revision.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Background:
- Acute aortofemoral graft occlusion presents a significant challenge in vascular surgery.
- While endovascular therapy is common, failure rates and complications necessitate further intervention, often surgical revision.
Observation:
- A patient with acute aortofemoral graft occlusion was treated using the Trellis thrombectomy-thrombolysis system.
- This system combines mechanical and local pharmacologic thrombus lysis.
Findings:
- The Trellis system effectively dissolved the thrombus, resolving the graft occlusion.
- Successful treatment with the Trellis system and subsequent stenting avoided the need for definitive graft revision surgery.
Implications:
- This case highlights the potential of the Trellis system as an effective endovascular treatment for aortofemoral graft occlusion.
- It offers a less invasive alternative to surgical revision, potentially reducing complications and recovery time.
Abstract:
Acute aortofemoral graft occlusion is often effectively treated with endovascular therapy but a substantial proportion of patients experience failure or complications of this therapy, and most of them require definitive surgery for the underlying inflow, outflow, or graft disease. We describe a case of an aortofemoral graft occlusion that was successfully treated with the Trellis thrombectomy-thrombolysis system (Covidien, Dublin, Ireland). Subsequent stenting of the graft obviated the need for a definitive graft revision surgery. The Trellis system combines mechanical and local pharmacologic lysis of the thrombus, with more rapid and more effective thrombus dissolution and theoretically less risk of systemic dispersion of the thrombolytic agent and less bleeding.
