Summary
A novel flow diverter effectively treated visceral artery aneurysms in nine patients, achieving complete occlusion with no major complications or mortality. This endovascular approach shows promise as a safe alternative to surgery.
Area of Science:
- Endovascular Surgery
- Vascular Interventions
- Aneurysm Treatment
Background:
- Visceral artery aneurysms (VAA) and pseudoaneurysms (VAPA) require tailored treatment strategies.
- Endovascular approaches, particularly flow diverters (FDs), have shown promising results for VAA/VAPA management.
Purpose of the Study:
- To evaluate the initial multicenter experience with a novel abdominal flow diverter (Derivo peripher FD).
- To assess the technical feasibility, safety, and efficacy of this new FD for treating visceral and abdominal aneurysms.
Main Methods:
- An observational multicenter study included nine consecutive patients with visceral or abdominal aneurysms treated with the Derivo peripher FD.
- Data collected focused on technical success, procedural safety, and treatment outcomes, including aneurysm occlusion and device patency.
Main Results:
- Complete aneurysm occlusion was achieved in 100% of patients at three months.
- All flow diverters remained patent during the follow-up period (up to 12 months for eight patients).
- No major complications, adverse events, or mortality were reported, indicating a favorable safety profile.
Conclusions:
- Endovascular treatment of abdominal and visceral aneurysms using the novel FD is effective and safe.
- The high occlusion rates and low complication profile suggest this FD is a viable alternative to surgical repair.
- This initial experience highlights the potential of FDs in managing complex visceral artery pathologies.
