摘要
the splenic artery aneurysm is an uncommon clinical entity, but is the most frequent among visceral aneurysms and is present in 0.8% of the population. it is more common in women, with a ratio of 4:1, and rarely causes symptoms or signs. it develops asymptomatically and, in most cases, is diagnosed by tests indicated to elucidate clinical complaints subsequent to other diseases or when there are fatal complications such as rupture. the possibility of rupture of splenic artery aneurysms with a diameter less than 2 cm is low; however, those with a diameter equal to or greater than 3 cm are usually referred for surgical treatment due to the high risk of rupture. the elective treatment is indicated for non complicated cases, and the coil embolization is an interesting method, since it avoids conventional surgical treatment.
