Early and long-term results of surgical treatment of splenic artery aneurysms

Background: This retrospective study was conducted to describe the presentation, surgical treatment, and follow-up of patients with splenic artery aneurysms. Methods: From 1982 to 2000, 1,952 patients with abdominal aneurysms were referred to our department; 15 had splenic artery aneurysms. None had ruptured. All were operated on. Results: Fourteen complete and 1 partial aneurysmectomies were carried out. Arterial continuity was restored in 10, by end-to-end anastomosis, and 4 had splenectomies. In 1 patient the spleen was preserved without arterial reconstruction. There were no deaths. Morbidity was restricted to 1 patient with a limited, asymptomatic splenic infarction. Eleven patients were followed up for a mean 19.7 months. No deaths or major complications were recorded. Reconstructed splenic arteries were patent in all cases without atrophy or new cases of splenic infarction. Conclusions: Elective surgery for splenic artery aneurysms is safe. Arterial reconstruction allows good early and long-term results. In some cases splenectomy may be unavoidable.
