Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot. [3]
Monckeberg's calcification typically occurs near the internal elastic lamina or, less frequently, in the media of muscular arteries without alterations in calcium metabolism. Its clinical importance is not yet fully understood. Some recent studies suggest a connection between Monckeberg's calcification and metabolic vascular calcification.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone , but calcium can be deposited abnormally in soft tissue , [ 1 ] [ 2 ] causing it to harden.
Macroscopically, splenosis manifests as individual pieces of reddish-blue tissue with variable shape, which can be as few as one and as many as 300, [4] mostly in the abdominal cavity, and varying in size from a few millimeters to as large as 12 cm. Due to the limited blood supply to these nodules, the typical size of splenic implants is ...

[10] [11] Atheroma and changes in the artery wall usually result in small aneurysms (enlargements) just large enough to compensate for the extra wall thickness with no change in the lumen diameter. However, eventually, typically as a result of rupture of vulnerable plaques and clots within the lumen over the plaque, stenosis (narrowing) of the ...
When atherosclerosis has become severe and caused irreversible ischemia, such as tissue loss in the case of peripheral artery disease, surgery may be indicated. Vascular bypass surgery can re-establish flow around the diseased segment of the artery, and angioplasty with or without stenting can reopen narrowed arteries and improve blood flow.
