Descending thoracic aorta remodeling after multilayer stent release

Abstract

The multilayer flow modulator (MFM) is a device whose real effectiveness in the treatment of thoracoabdominal aortic aneurysms is not clear yet. A 68-year-old man with a 18-mm blister-like aneurysm of the descending thoracic aorta underwent endovascular exclusion, complicated by the thrombosis of a previous aortobi-iliac prosthesis, treated with embolectomy and femorofemoral bypass. Therefore, an MFM placement was planned. The postoperative course was uneventful and the 6-month computed tomography scan showed a complete thrombosis and remodeling of the aneurysm. The MFM stent could be an alternative treatment for saccular thoracic aortic aneurysm in high-risk patients but should not be used indiscriminately when other modalities of aortic repair are not feasible. Longer follow-up is mandatory to prove the efficacy of this technology.
