Its size was as big as the pancreatic head and it was observed that 1.5 cm posterior inferior PDA aneurysm was present (Fig. 1).
Abdominal contrast-enhanced computer tomography (CT) shows residual extravasation of contrast inside the aneurysm sac after transcatheter embolization of inflow and outflow of the aneurysm with microcoils (white arrow).

Another CT scan had been conducted, which revealed residual flow inside the aneurysm sac fed by small collateral vessels (Fig. 2).
Super-selective catheter angiography showing collateral vessels that feed the aneurysm sac after embolization of inflow and outflow of the aneurysm with microcoils (A). Definitive haemostasis was obtained by embolizing collateral vessels with microcoils and a cyanacrylate/lipiodol mixture (B).

Sub-selective catheterization was repeated and definitive hemostasis was obtained by embolizing the collateral vessels with microcoils and a cyanacrylate/lipiodol mixture (Fig. 3, Fig. 4).
