PAVM is a rare but fatal disease in many cases. Patients may be asymptomatic or present dyspnea, cyanosis, and polyglobulia. However, complications such as paradoxical thromboembolism, brain abscess, and massive hemoptysis are causes of higher morbidity and mortality. This article presents 3 patients with PAVM who underwent lobectomy between 2014 and 2018. The clinical and surgical data were obtained from their medical records. In the 3 cases, pulmonary lobectomy was performed, 2 received hybrid treatment: previous embolization and pulmonary surgery. The mean age was 41.3 years. The main symptom was cyanosis. In 1 case the affection was in a single lobe; in 2 cases it was complex. We consider that surgery is the first treatment option, especially when the PAVM is localized and greater than 5cm or when transcatheter embolization cannot be performed.
