ABSTRACT
We present an 82-year-old man with a history of hairy cell leukemia, having an 11-cm abdominal aortic aneurysm, who also had severe thrombocytopenia (about 20 000 platelets/µL) and splenomegaly at presentation. 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/µL), 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's preoperative status in order to avoid bleeding complications.
