摘要
The relationship between pulmonary arteriovenous malformations (PAVMs) and stroke remains unclear. With the development of imaging technology, studies shows that PAVMs are an important cause of cryptogenic stroke (CS). Most PAVMs are not diagnosed until the onset of stroke. The main pathogenesis of PAVMs-related CS is paradoxical embolism and increased blood viscosity caused by iron deficiency anemia. Antiplatelet therapy and interventional therapy may have a preventive effect on recurrent stroke in such patients. This article summarizes the pathophysiological mechanism, diagnosis and treatment of PAVMs-related CS, hoping to provide new ideas for the diagnosis and treatment of CS.
