Vascular Surgery 26 years experience Possibly: Most splenic artery aneurysms are not at any significant risk of rupture & bleeding until they reach around 20 mm so most vascular surgeons recommend following them annually until they reach that size, then repairing them at that time (most often with embolization or stenting rather than surgery ). On its course, the splenic artery gives off several branches to the pancreas and stomach. The size of the splenic artery was found to be unrelated to the nature of the underlying disease, age of the patient, or history of variceal bleeding. The combination of both anomalies is common in elderly persons presenting without symptoms of splenic ischemia.
