- Abstract
Hereditary hemorrhagic telangiectasia (HHT) usually presents in association with pulmonary arteriovenous malformations (PAVMs). In addition, the incidence of venous thromboembolism tends to be increased in these patients. A 74-year-old female with HHT presented with cyanosis and hypoxemia. Contrast-enhanced multislice computed tomography (MSCT) revealed two left PAVMs and one in the right upper lobe. Both left PAVMs were treated with embolotherapy. Follow-up MSCT revealed an incidental pulmonary embolism in the right pulmonary branches. Deep venous thrombosis was confirmed and anticoagulation was initiated. Follow-up MSCT revealed the resolution of thromboembolism. Finally, embolotherapy was performed. This case illustrates the chronic adaptation to hypoxemia and adds further evidence to the relative safety of anticoagulation treatment in these patients.
