Objective. Presenting early and midterm results of aortic and iliac artery aneurysms treated with Multilayer Flow Modulators (MFM). Methods. We retrospectively reviewed the medical records of 23 patients (19 males and 4 females) who are admitted to our clinic between April of 2014 and February of 2016, diagnosed with thoracoabdominal aortic aneurysm and/or iliac aneurysm, and treated using MFM. The patientswere followed up for the development of potential clinical presentations for 12 months. Results. MFM implantation was successfully completed in all the patients. During the process, two patients developed endoleak and so they were treated with postdilatation that was performed through balloon intervention, whereby the patients fully recovered. Although a short-termischemic cerebrovascular event occurred in one of the patients 36 hours after the MFM, the patient recuperated without any noticeable neurological sequelae. Overall, three patients died after the procedure, one of whom died in hospital three days following the intervention due to acute renal failure, while the second one lost his life at the end of the first month due to the occlusion of superior mesenteric and celiac arteries. The third patient died at the end of the third month due to acute myocardial infarction. The rest of the patients developed no complications or had no mortality at their 12-month follow-ups. Conclusion. MFM can be preferred as an alternative approach in the treatment of aorta and iliac artery aneurysms including major lateral branches. The present results should be confirmed with additional future studies conducted with larger patient groups for longer periods.
