Generally speaking, splenic artery aneurysm embolization cannot treat splenic necrosis, but it can avoid hemorrhage caused by rupture of splenic artery aneurysm. Splenic artery aneurysm is an aneurysm formed after dilatation of the splenic artery, most of them have no obvious symptoms, and the patient may have occasional discomfort in the left upper abdomen. Once the splenic artery aneurysm ruptures, it will cause hemorrhage and the mortality rate is very high, so it can be treated by embolization. The main treatment for splenic necrosis is splenectomy as soon as possible to prevent acute hemolysis and sepsis of abdominal abscess caused by splenic necrosis, etc. Splenic necrosis can be life-threatening. In summary, splenic aneurysm embolization is not a treatment for splenic necrosis, it can prevent hemorrhage caused by rupture of splenic aneurysm. If patients suspect that they have splenic necrosis, they must go to the hospital as soon as possible, and after perfect examination and clear diagnosis, they should have surgical treatment as soon as possible.
