How serious is a 9 mm partly calcified splenic artery aneurysm? i have been hurting for some time now and now i sick worrying. what should i do?

See Vascular Surgeon: It would be unlikely that a splenic artery aneurysm of that size would be causing pain, but it is possible. Most splenic aneurysms are asymptomatic & not repaired until they reach over 20 mm. If the aneurysm is felt to be causing pain or getting larger quicker than usual, then you could be considered for repair (usually embolization or stent). See a board-certified vascular surgeon for opinion.

How are you feeling?: Splenic artery aneurysms, although more common than other visceral aneurysms, are quite rare. This makes it very difficult to draw conclusions. Pregnancy has been associated with increased incidence of rupture of these anomalies. It sounds like you've had some kind of evaluation and, particularly if you are having symptoms, I would return to your doctor to address the source of your unease. GL!
