A Case of Aortic Arch Thrombus Associated with Acute Pyelonephritis in a Patient with Thrombocythemia / 대한신장학회잡지

ABSTRACT

Aortic thrombus is a rare but life threatening disorder. The usual causes of aortic thrombus are primary or secondary thrombocythemia, malignancy, atherosclerosis, trauma, and acute infectious disease. Here, we report a case of aortic arch thrombus associated with acute pyelonephritis in a patient with thrombocythemia. A 78-year-old woman was admitted with acute pyelonephritis. A complete blood cell count showed severe thrombocythemia with platelet count of 1, 340, 000/mm3. Chest CT scan demonstrated floating thrombus in the aortic arch. After antibiotic treatement, platelet count decreased to 770, 000/mm3 and aortic thrombus disappeared without thrombolytic therapy.
