There are multiple technical considerations for endoluminal exclusion of splenic artery aneurysms; treatment options are dictated by anatomy and patient characteristics. PDF | Vascular diseases of the spleen are relatively uncommon in clinical practice. It was first described in 1981 by Sclafani [ 3] and became more widely used in the late 1990s. Estimates of their true prevalence vary widely, ranging from 0.098% in a study of 195,000 autopsies to 0.78% in a study of 3,600 arteriograms to 10.4% in an autopsy study of patients older than 60 ( 1, 2, 3 ).
