A rare vascular complication in a patient with essential thrombocythaemia: spontaneous abdominal aortic dissection

A 27‐year‐old woman complained of waist and back pain. Abdominal computed tomography angiography showed abdominal aortic dissection, the blood count revealed a high platelet count of 1655 × 10 9 /L. Negative for JAK2V617F , CALR and MPL mutations (i.e. triple‐negative), the patient was diagnosed as essential thrombocythaemia ( ET ) with abdominal aortic dissection and was treated with cytoreduction and antiplatelet drugs. Cases of abdominal aortic dissection in ET have not been previously reported. As such, we proposed a mechanism of abdominal aortic dissection caused by endothelial dysfunction and further emphasised appropriate management in ET with abdominal aortic dissection .
