Abstract:

Presenting early and mid-term results of iliac artery aneurysms treated with the Multilayer Flow Modulator (MFM). The MFM was used to treat 14 aneurysms involving the internal and external iliac arteries (complex iliac artery aneurysm). The procedure was performed under local anesthesia implemented through femoral artery. Effective implantation of MFM within the aneurysmal area without complications was defined as a successful intervention. Patients were followed for the development potential clinical presentations during 12 months.  A total of 8 out of 14 aneurysms were presented with complex iliac artery aneurysm and they were successfully treated using MFM. While itiac artery aneurysm was bilateral in six patients, it was unilateral in two patients. In addition, 6 patients were male and two patients were female with average age of 64 ranging from 56 to 72.  Type 1 endoleac occurred in one patient. Endovascular re-intervention was performed (ballooning) and the endoleak was successfully treated. The creatinine level increased to 2.1 mg/dl on the 2nd post-operative day in one of the patients but the patient didn’t need any dialysis and his kidney functions returned to normal on the 7th day after the operation. Moreover, right-liiac artery occlusion occurred in one of the patients on the 30th day after the operation and the occlusion was treated with thrombectomy then ballooning and stenting. No other complications developed either during or after the process. MFM stents appeared to be effective and safe in the treatment of complex iliac artery aneurysms. Our results need to be supported by larger and longer-term follow-up studies.
