(a) Computed tomography angiogram (CTA), coronal reconstruction view, showing Type Ia endoleak filling aneurysmal sac. (b) CTA sagittal reconstruction view demonstrating the type Ia endoleak associated with an outflow through a patent lumbar vessel (green arrow) that potentially will cause a type II endoleak.

Urgent abdominal computed tomography (CT) detected an 88-mm aneurysmal sac and type I endoleak-like phenomenon associated with an outflow through a patent lumbar vessel (Fig. 1a & b) that had the potential to develop a late type II endoleak.
Digital subtraction angiography (DSA) demonstrating outflow type II endoleak into patent lumbar artery and branches (green arrow).
