Background The aim of this study was to analyze our series of endovascular treatments using a multilayer flow modulator (MFM) and to show the midterm results. Methods At our institution, 8 patients were treated with an MFM. Four patients presented with an aortic aneurysm (2 type II thoracoabdominal aortic aneurysms [TAAAs], 1 type IV TAAA, and 1 juxtarenal abdominal aortic aneurysm) and 4 with an aneurysm involving the common iliac artery. Mortality, rupture and secondary intervention, major complications, patency of collateral vessels, and volume analysis were evaluated. Treated patients were followed up with computed tomography angiography at 1, 3, 6, and 12 months. Results Results showed no 30-day mortality or major complications; technical success was achieved in 87.5% of patients, patency of collateral vessels was reached in all cases at intraoperative completion angiography. Mean follow-up was 22.1 months (range, 18-30), survival rate was 87.5%, and one case of death unrelated to MFM treatment was reported. During follow-up, MFM and collateral vessel patency were observed in all cases. Secondary endovascular or open surgical procedures were not needed during follow-up. Volume analysis showed a slight increase in patients with aortic aneurysm, and an overall trend to increase in thrombosis was observed in all cases. Conclusions Endovascular treatment of aneurysms with MFM seems to have encouraging midterm results. Should our results be confirmed by larger series and longer follow-up studies, MFM may become a viable alternative to other endovascular approaches.
