Incidentally, an aneurysm of the posterior gastric artery was identified (normal vessel 2 mm; aneurysmal vessel 12 mm; Fig. 1).

Catheterisation of the posterior gastric artery was performed using a 0.014 inch guidewire (ProVia 9 Guidewire, Medtronic, Minneapolis, MN, USA) supported by a 4F 110 cm straight catheter (Radiofocus Glidecath, Terumo Corporation, Japan). Coil embolisation was performed in the aneurysmal sac (it was not possible to catheterise the outflow vessel) and in the afferent vessel, using 3/2 coils (Tornado coils, Cook Medical, Bloomington, IN, USA) (Fig. 2).

The six month follow up CTA revealed exclusion of the aneurysm, maintenance of the splenic flow and no splenic or gastric infarction (Fig. 3).
