The patient had unfavorable anatomy for endovascular aneurysm repair, and therefore, an open procedure was planned. To reduce risk for perioperative bleeding and optimize patient preoperative status, a staged approach was employed. Initially, several sessions of embolization of 2 splenic artery branches were performed with the intent to decrease spleen size and to increase platelet count thus decreasing the perioperative bleeding risk. Then, after successfully increasing platelet count (280 000 PLT\/\u03bcL), open repair of the aneurysm was conducted. This case demonstrates that selective splenic embolization in patients with hypersplenism and subsequent thrombocytopenia who are in need for major surgery may achieve a significant rise in platelet count and optimize patient\u2019s preoperative status in order to avoid bleeding complications.<\/jats:p>","DOI":"10.1177\/1538574416666222","type":"journal-article","created":{"date-parts":[[2016,8,31]],"date-time":"2016-08-31T21:29:20Z","timestamp":1472678960000},"page":"438-442","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Selective
