[Splenic artery aneurysm: diagnosis and endovascular therapy]. / Anévrisme de l'artère splénique: diagnostic et thérapeutique endovasculaire.

Splenic artery aneurysms are now diagnosed more frequently thanks to the increase and improvement in different imaging techniques. In case of rupture they are potentially life threatening and thus in certain cases may require appropriate preventive treatment. This treatment should be offered to patients with suspected pseudoaneurysms, with an aneurysm larger than 20mm in diameter, or which is progressing. The development of interventional endovascular radiology has provided new therapeutic options for the management of aneurysms, by excluding the sac from the arterial circulation with coil embolisation or with a covered stent. The success rate of these treatments is between 75 and 100% with significantly less morbidity and mortality than with surgical techniques.
