ALTHOUGH aneurysms of the splenic artery are often considered the most common type of intra-abdominal aneurysm, excluding those of the aorta,1 they are infrequently encountered in the average clinical practice. In recent years, however, splenic artery aneurysms have been reported with increasing frequency, and as the population grows older it may be anticipated that this trend will continue. Changing attitudes regarding this clinical entity have become apparent from the increasing number of reports advocating a conservative approach with close observation as the only treatment.2-4 Much confusion has, therefore, arisen concerning which therapeutic approach will result in the lowest patient morbidity and mortality. It is the purpose of this communication to review the problems associated with aneurysms of the splenic artery and to deal with certain controversial aspects of their management. An analysis of our own clinical and autopsy experience is also given.
