Diffuse vasculopathy in a patient with Marfan syndrome
摘要
Marfan syndrome (MFS) is a hereditary connective tissue disorder, primarily affecting the cardiovascular, skeletal, and ocular systems. Cardiovascular complications, particularly aortic aneurysm and dissection, are the leading causes of morbidity and mortality in these patients. We present the case of a 45-year-old woman with MFS who underwent a Bentall-De Bono procedure for type B aortic dissection. She later developed Staphylococcus aureus prosthetic valve endocarditis, complicated by periprosthetic infection and embolic events. Despite long-term suppressive antibiotic therapy, she discontinued treatment due to gastrointestinal intolerance. Follow-up imaging, including echocardiography, PET/CT, and CT angiography, revealed an unchanged aneurysm in the descending thoracic aorta with a dissection flap but no active infection. Given the absence of new complications, conservative management was chosen. This case highlights the importance of multimodal imaging and individualized treatment strategies in MFS patients with complex cardiovascular history.
