Discussion (Related Text)

The splenic artery is the commonest site of visceral arterial aneurysm formation as well as the 3rd commonest site of aneurysm formation in the abdomino-pelvic region (after the aorta and iliac vessels). Aneurysms are usually saccular in configuration. They can either be in the form of a
•splenic artery true aneurysm: (much more common)
•splenic artery pseudoaneurysm
Most often splenic artery aneurysms are detected incidentally on imaging for some other cause. Occasionally they can present acutely with a rupture .
•fibromuscular dysplasia
•cirrhosis 3
•portal hypertension 3
The overall risk of rupture is thought to be ~2-10%. However in an event of rupture there is a relatively high mortality rate of ~36% .
Follow-up of incidentally-detected splenic artery aneurysms :
• < 2cm ◦spontaneous rupture is rare 1 year follow up, if no risk factors follow up interval may be extended if other comorbidities are present, or if there is a decreased life expectancy •≥2 cm ◦endovascular therapy should be considered coil embolisation is increasingly used to treat larger aneurysms rapidly increasing size, presence in a premenopausal woman, cirrhosis, and symptomatic aneurysm may warrant intervention, regardless of size
