Background:
Type 3 endoleak (T3E) is usually treated by endovascular relining. The procedure can be technically complex in cases of endografts with kinking of innermost stents. We report a case of T3E in an AFX (Endologix, Irvine, CA, USA) endograft with sac enlargement, billowing, and severe kinking of the main body stents, managed with a complete relining endovascular procedure.
Methods:
A 69-year-old man with severe comorbidities and prior aorto-bi-iliac AFX endograft completed by an Endurant II cuff (Medtronic, Santa Rosa, CA, USA) for a 63-mm asymptomatic infrarenal aneurysm was admitted to our department for a T3E with 7-mm sac enlargement. The computed tomography angiography (CTA) showed perfusion of the aneurysmal sac, AFX fabric disconnection from its stent (billowing), and severe stent kinking of the main body without a residual lumen. A digital subtraction angiography confirmed the T3E. A complete relining was performed by deploying a bifurcated Endurant II through the AFX stents.
Results:
The 1-year CTA proved the resolution of the endoleak with a stable aneurysmal sac diameter.
Conclusions:
In case of T3E with severe main body stent kinking and graft billowing, an endovascular procedure with a complete aorto-bi-iliac relining through inner stents may be considered.
