Stent graft for popliteal aneurysms. Six cases with Cragg Endo-Pro System 1 Mintec
1Clinique du Mail, La Rochelle, France.
Insights
Transluminal exclusion using the Cragg Endopro System stent-graft successfully treated most popliteal aneurysms. While complications occurred, this minimally invasive approach shows promise, particularly for high-risk patients.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Medical Device Technology
Background:
- Popliteal aneurysms are a common peripheral arterial aneurysm.
- Traditional surgical repair carries significant morbidity.
- Endovascular repair offers a less invasive alternative.
Purpose of the Study:
- To evaluate the safety and efficacy of the Cragg Endopro System stent-graft for treating popliteal aneurysms.
- To assess the midterm patency and complication rates of this endovascular technique.
Main Methods:
- Six patients with popliteal aneurysms underwent transluminal exclusion.
- The Cragg Endopro System 1 stent-graft, manufactured by MINTEC, was utilized.
- Follow-up included clinical assessment and imaging to monitor patency and complications.
Main Results:
- Four out of six patients maintained patent stent-grafts at follow-up periods ranging from 1 to 9 months.
- One patient experienced incomplete distal exclusion leading to recurrent aneurysm at 6 months.
- Another patient developed thrombosis at 7 months, successfully treated with fibrinolysis and an additional stent.
Conclusions:
- Transluminal exclusion with the Cragg Endopro System stent-graft demonstrates encouraging initial results for popliteal aneurysms.
- Complications such as incomplete exclusion and thrombosis require careful management.
- Stent-grafting for popliteal aneurysms may be best suited for elderly patients or those in poor condition, warranting further investigation.
Abstract:
Six popliteal aneurysms were treated by transluminal exclusion with the Cragg Endopro System 1, a Stent-Graft manufactured by MINTEC. In one case, incomplete distal exclusion has led to a recurrent aneurysm at 6 months. In one case thrombosis occurred at 7 months, with successful reopening by fibrinolysis and an additional stent. The 4 other cases remained patent at 9, 8, 4 and 1 month. Despite these encouraging results, the stent-grafting of popliteal aneurysms seems still to be reserved for elderly or poor condition patient.
