PURPOSE: Pulmonary arteriovenous malformation (PAVM) embolization has traditionally been performed as an inpatient procedure, often with sequential procedures to treat multiple lesions. This approach is costly, inconveniences the patient, and may lead to noncompliance with embolotherapy. In the authors' hereditary hemorrhagic telangiectasia (HHT) center, all PAVM embolizations in teenagers and ...
