Stenting complex aorta aneurysms with the Cardiatis multilayer flow modulator: first impressions.

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Aneurysm Treatment

Background:

• Complex aortic aneurysms often present challenges for standard endovascular repair.
• The Cardiatis multilayer flow modulator (MFM) is an innovative device designed for challenging aortic pathologies.

Purpose of the Study:

• To evaluate the feasibility and efficacy of the Cardiatis MFM in treating complex aortic aneurysms.
• To assess the safety and performance of the MFM in patients unsuitable for conventional stent grafts.

Main Methods:

• A single-center prospective registry study.
• Six patients with complex aortic aneurysms were treated with the Cardiatis MFM.
• Median follow-up duration was 10 months.

Main Results:

• 100% clinical success rate observed.
• Complete aneurysm thrombosis occurred in 4 patients within 1-6 months.
• 100% patency of covered aortic branches was maintained.
• No device-related complications like migration, thrombosis, or fractures were reported.

Conclusions:

• The Cardiatis MFM effectively preserves flow into aortic branches and facilitates gradual aneurysm thrombosis.
• The device did not prevent immediate postoperative rupture in one case.
• Longer follow-up is essential to confirm the long-term efficacy of the Cardiatis MFM.
