Percutaneous EVAR for Ruptured Abdominal Aortic Aneurysms Using the Cordis INCRAFT Endograft

Abstract

Objectives: Low profile endovascular aneurysm repair (EVAR) devices such as the Cordis INCRAFT AAA Stent Graft System may expand the category of patients suitable for endovascular repair. We report our experience with the INCRAFT system in treating ruptured abdominal aortic aneurysms (rAAA).

Methods: We included all patients presenting with rAAA from 2015 to 2019 in our hospital who were treated by percutaneous EVAR with the INCRAFT system. The primary outcome was technical success, referring to adequate stent graft placement. Secondary outcomes included completion of the procedure under local anesthesia and mortality at 30-days, one year and long-term follow-up.

Results: Fifteen male patients (mean age: 74 years, SD 6.7) were treated for rAAA with a median aneurysm diameter of 8.25 cm (SD 1.66). The device was successfully delivered and deployed in all subjects. Per-procedurally one type I endoleak required additional stent placement and one patient developed an acute thrombosis of the device main body and iliac limbs requiring thrombectomy. 80.0% of patients were successfully treated under local anesthesia only. The 30 day and one year mortality were 26.6% and 33.3% respectively. Long-term survival was 60.0% at a median follow-up period of 57 months, with two patients requiring late reintervention for an endoleak.

Conclusions: The INCRAFT system can be used to percutaneously treat rAAA with a high technical success rate and mortality similar to reported in the literature for other devices. The large majority of procedures can be completed with only local anesthesia.
