“…Skibba et al [6] by including 701 patients treated with the Endologix Powerlink and AFX platforms during a 8-year period, reported only 3 graft thrombosis that needed reintervention (0.4%). Moreover Carpenter et al [12] by reporting results from 3 Investigational Device Exemption studies found a 1.9% limb occlusion rate. More data are needed to confirm the exact behavior of AFX iliac limbs in the long term as well as in hostile iliac anatomy.…”

PurposeThe newly designed unibody AFX endograft system for endovascular aortic aneurysm repair is the only graft with anatomical fixation to the aortic bifurcation in comparison to most other grafts that use the infrarenal neck as the main fixation point. The aim of this study was to assess the preliminary results of the AFX stent-graft system used with infrarenal aortic component and compare them with those obtained in patients treated with a well established endograft of the same material and pure infrarenal fixation as the Gore Excluder.Materials and MethodsA retrospective analysis of prospectively collected data from March 2014 to December 2014 identified 10 elective abdominal aortic aneurysm patients treated with the AFX endograft, in comparison to a matched group of 20 patients treated with the Excluder stent-graft. Endpoints included technical and clinical success, freedom from any secondary intervention, any type of endoleak and aneurysm related death.ResultsPrimary technical success was achieved in all patients and no 30-day device related complications or deaths were occurred. The two groups were similar in terms of radiation burden, contrast media, duration of the procedure, post implantation syndrome and in-hospital stay. During a median follow-up period of 23 months (range, 18–26 months) there were no differences in clinical success, freedom from reintervention and aneurysm related death. No type I endoleak was observed in either group. Five of the 6 type II endoleaks (1 in the AFX and 4 in the Excluder group) spontaneously resolved, while in only one patient (Excluder) the endoleak remained without however any change in aneurysm sac diameter (log rank=0.34).ConclusionThe initial experience with the AFX stent graft system is promising, with successful aneurysm exclusion and good short-term results. Further and larger studies are needed to fully evaluate the sort as well as the long-term results.

“…This technique is named as ''anatomical fixation'' by us, and it has been shown to be effective in preventing distal migration in hostile neck AAAs. [15][16][17][18][19] Similarly, this technique can be utilized in endovascular repair for patients who have PPAAs with hostile necks. Moreover, unibody stent graft is directly deployed sitting on the aortic bifurcation and does not need to cannulate the contralateral limb so the procedure is quite simple and quick, very suitable for emergent case.…”

Endovascular repair of abdominal aortic aneurysms emerged initially as an alternative treatment strategy for patients considered to be inoperable or high risk for surgery. The evolution of endovascular techniques has made this technology a safe and less invasive alternative to open surgery for patients with suitable aortic anatomy. This manuscript reviews the current state of the art for endovascular AAA repair techniques, clinical outcomes, guideline recommendations, and future applications.
