[Embolization of splenic artery aneurysms: Treatment of choice. About a case and review of the literature].

Splenic artery aneurysms constitute 60% of digestive artery aneurysms. They are often discovered incidentally and by imaging. Currently, endovascular treatment is considered the first-line treatment, as it is less invasive with less morbidity and mortality than surgery. An aggressive approach in their management is certainly justified because the overall mortality of ruptured splenic aneurysms is 25%. False splenic aneurysms have a greater potential for rupture than true aneurysms because they grow faster. Endovascular treatment is generally indicated for aneurysms larger than 2cm or with an increase in size of more than 0.5cm/year. Embolization is rarely associated with an infarction of the spleen due to the good supply of short gastric vessels. Embolization is performed using different materials including coils, which can be used alone or with other embolic agents. Post-embolization syndrome can be seen with persistent pain, fever and other systemic symptoms. Endovascular treatment compared to open surgery is associated with better quality of life and appears to be the most cost-effective strategy. Endovascular treatment and especially coil embolization are starting to be the standard treatment. Surgical and laparoscopic treatment are reserved for ruptured aneurysms which are burdened with significant mortality, especially in pregnant women. We report the case of a 66-year-old female patient in whom a splenic artery aneurysm was discovered incidentally during an ultrasound for an ovarian cyst.
