Nonatherosclerotic Abdominal Vasculopathies.

Background: Nonatherosclerotic abdominal arterial vasculopathies (NAVs), including mesenteric or renal artery dissection, aneurysm, stenosis, and vasculitis, are rare but have great clinical significance. Patients may present emergently with life-threatening complications such as arterial rupture and hemorrhagic shock. Herein, we present our center's experience with NAVs and provide extensive literature review to close the gap in the scarce, related literature.

Medical Management of Extensive Arterial Thromboembolism in a Patient with Essential Thrombocythemia and Warfarin Failure.

Chronic myeloproliferative disorders share a stem cell-derived clonal myeloproliferation. This group of disorders include essential thrombocythemia (ET), polycythemia vera (PV), chronic myeloid leukemia, and primary myelofibrosis (PMF), with the respective features of thrombocytosis, erythrocytosis, and bone marrow fibrosis. These disorders can be associated with genetic mutations affecting protein tyrosine kinases, resulting in different configurations of abnormal signal transduction.

Large thoracic aortic aneurysm and dissection with rare complication.

Thoracic aortic aneurysms can be found incidentally, however, patients can also present with acute dissection and or rupture that can be fatal. Symptoms that might indicate dissection include chest and back pain as well as lightheadedness. The diagnosis can be made with imaging studies such as computed tomography or magnetic resonance angiogram and sometimes transesophageal echocardiogram.
