Fistulectomy as a surgical option for pulmonary arteriovenous malformation

Abstract

Background: Surgical resection remains the treatment of choice for pulmonary arteriovenous malformation but removes some normal lung parenchyma. This study aimed to evaluate the effect and safety of the lung-saving procedure of fistulectomy as an alternative to lung resection.

Methods: From July 2003 to July 2008, 6 selected patients with pulmonary arteriovenous malformations underwent fistulectomies. Among them, 1 patient underwent emergency operation and 2 underwent bilateral operations. One patient received postoperative embolotherapy.

Results: No hospital deaths or postoperative morbidity occurred. PaO2 increased significantly after operation. All patients were free of symptoms and hypoxia during a follow-up for 9 months to 5 years.

Conclusions: Fistulectomy is a safe and effective procedure for patients with pulmonary arteriovenous malformation and may be an alternative to lung resection.
