Abdominal Aortic Aneurysm with Essential Thrombocythemia: A Case Report Describing Perioperative Management in Open Surgery.

We report perioperative management and open surgery to treat a case of infrarenal abdominal aortic aneurysm with essential thrombocythemia (ET), a chronic myeloproliferative disorder associated with arterial or venous thrombosis, idiopathic bleeding, and heparin-resistant diathesis. Following careful preoperative management, including assessment of heparin resistance, open surgery was successfully performed to treat the aortic aneurysm of our patient. This report shows that optimal preparation for surgery is important to safely perform abdominal aortic aneurysm repair and prevent perioperative thrombosis and bleeding in patients with abdominal aortic aneurysm with ET.
