A 56-year-old man underwent replacement of the ascending aorta with a sutureless intraluminal graft, for a Stanford type A aortic dissection. Eight years after the operation, he developed gross hemoglobinuria, associated with an intravascular hemolytic anemia. Due to numerous schistocytes in the peripheral blood, the hemolysis was attributed to mechanical injury of the red blood cells at the site of the vascular graft. The patient's course was complicated by an infection of the aortic graft, which led to an urgent graft replacement. The hemolytic anemia resolved completely shortly after the reoperation. Physicians should consider this etiology in the differential diagnosis of fragmentation hemolytic anemia.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
