Arterial thrombus can occur after splenectomy, but limited information exists specifically for patients with immune thrombocytopenic purpura (ITP).
A 52-year-old woman with significantly low platelet counts underwent splenectomy following treatments that didn't effectively raise her platelet levels.
Post-surgery, she experienced pain and pallor in her right arm due to a mural thrombus, leading to partial blockage in the aorta, which was further complicated by an unusual artery structure and inflammatory thrombocytosis.
