Clinical Trial Summary

This is a multicentric voluntary observational study with a retrospective evaluation of prospectively collected data concerning the treatment of visceral aneurysms with flow diversion stent Derivo Peripher and Derivo 2 (DED, Acandis GmbH) Follow-up will include clinical and radiological (CT) evaluation at least 12 months after the intervention. The enrollment period will be of 54 months (01/01/2020-30/06/2024). Minimum sample size will be of 50 Patients.

Eligibility

Inclusion Criteria:

• >18 years old

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy of the stenting in terms of patency and side branches	stent patency and side branches (the absence of stenosis greater than 50% of the stent's internal lumen and the side branches' lumen)	12 months
Primary	Efficacy of the stenting in terms of aneurysm thrombosis rate	aneurysm (partial or complete, >50% or 100%) thrombosis	12 months
Primary	Efficacy of the stenting in terms of aneurysm volume assessment	aneurysm volume assessment (percentage of volume reduction respect to the initial volume)	12 months
Primary	Safety in terms of morbidity	morbidity (any adverse events occured during follow up for any causes and by causes associated with treatment)	12 months
Primary	Safety in terms of mortality	mortality (any cause of death related to pathology or not)	12 months
Primary	Safety in terms of technical issues	technical issues (any adverse event during stent placement)	12 months
