Insights
Percutaneous treatment of iliac aneurysms using covered stents is feasible. This minimally invasive approach demonstrated high success rates and long-term patency in a small patient cohort.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Device Technology
Background:
- Iliac artery aneurysms pose a significant risk of rupture and complications.
- Traditional open surgical repair can be associated with substantial morbidity.
- Minimally invasive endovascular techniques are increasingly explored for treating complex vascular pathologies.
Observation:
- A covered stent was successfully deployed percutaneously in nine male patients with iliac aneurysms (common, external) or pseudoaneurysms.
- One patient experienced early endoprosthesis thrombosis, successfully managed with thrombolysis and additional stenting.
- All stent-grafts remained patent without late leakage or stenosis during a mean follow-up of 22 months.
Findings:
- Percutaneous stent-graft placement is a technically feasible and effective treatment for iliac artery aneurysms.
- The procedure achieved high technical success and durable midterm patency.
- Early complications, such as thrombosis, are manageable with appropriate interventions.
Implications:
- This approach offers a less invasive alternative to open surgery for selected patients with iliac aneurysms.
- Covered stent-grafts represent a promising option for endovascular management of these conditions.
- Further research with larger cohorts is warranted to confirm long-term outcomes and expand indications.
Abstract:
To evaluate the feasibility of percutaneous treatment of iliac aneurysms, a covered stent was inserted in nine men suffering from common iliac artery aneurysms (six cases), external iliac aneurysms (one case), or pseudoaneurysms (two cases). Placement of the stent was successful in all patients. In one patient, an endoprosthesis thrombosed after 15 days, but was successfully treated by thrombolysis and additional stent placement. At the follow-up examinations (mean period 22 months) all stent-grafts had remained patent. No late leakage or stenosis was observed.
