  • Title: Successful endovascular management of giant splenic artery aneurysms.
    Author: Ho MF, Chan YC, Cheng SW.
    Journal: Vascular; 2013 Oct; 21(5):317-22. PubMed ID: 23493275.
    Abstract:
    Giant pseudoaneurysms of the splenic artery, with a diameter of 5 cm or more, are rare surgical emergencies, and conventional open surgery usually involves splenectomy. The aim of this study is to report two cases from our institution and to review the world's literature on successful endovascular treatment of patients with giant splenic artery pseudoaneurysms. A retrospective review of a prospectively entered departmental computerized database was performed for the two patients from our institution. Articles were searched electronically from PubMed and Medline, using the terms 'giant splenic artery', 'endovascular' and 'embolization'; and relevant cases were reviewed from the world's literature. We hereby report two patients with giant splenic artery pseudoaneurysms who were treated successfully with endovascular procedures. In addition to the two patients from our institution, there were five patients with giant splenic artery pseudoaneurysms in the published literature who underwent successful endovascular management. The first patient of our series had the largest pseudoaneursym size of 7.2 × 8.1 cm, which is the largest documented pseudoaneursym in the current literature. We report two cases of giant splenic artery pseudoaneurysm with one being the largest pseudoaneurysm treated with endovascular technique in the current literature. Endovascular coil embolization of main trunk of splenic artery is less invasive than open surgical treatment for giant splenic artery pseudoaneurysm, and circumvents the problem of difficult exposure, especially in those patients with significant co-morbidity.
