Although con­sid­ered ­rare pathol­o­gies, splen­ic ­artery aneu­rysms are ­more fre­quent­ly diag­nosed ­today ­owing to mod­ern imag­ing ­systems. The splen­ic ­artery is the ­most fre­quent ­site of ­this ­lesion, account­ing for ­over 60% of all vis­cer­al ­artery aneu­rysms. In par­tic­u­lar, 0.2-0.8% of the gen­er­al pop­u­la­tion is affect­ed by ­this pathol­o­gy, ­although the inci­dence in ­females is ­four ­times high­er ­than in ­males. The rela­tion­ship ­between the fre­quen­cy of ­this pathol­o­gy and the ­female sex has ­been cor­re­lat­ed ­with alter­a­tions occur­ring in the splen­ic ­artery dur­ing preg­nan­cy, char­ac­ter­ised by rup­ture of the inter­nal elas­tic lam­i­na, frag­men­ta­tion of the elas­tic ­fibres and the accu­mu­la­tion of pro­te­og­ly­cans in the tuni­ca ­media. We ­report a ­case of splen­ic ­artery aneu­rysm in ­which fail­ure of the ­first embol­isa­tion pro­ce­dure ­using tung­sten ­coils ­called for sub­se­quent treat­ment ­with plat­i­num ­coils two ­months lat­er. In addi­tion to com­plet­ing the embol­isa­tion of the aneu­rys­mat­ic sac, ­this led to the occlu­sion of the splen­ic ­artery prox­i­mal to the aneu­rysm. Owing to the ­fact ­that angio­gra­phy, ­colour Doppler ultra­so­nog­ra­phy and angioMR had ­shown ade­quate splen­ic per­fu­sion ­through col­lat­er­al branch­es, the ­organ was con­served with­out resort­ing to sur­gi­cal remov­al.
