Abstract:
Objective To analyze the efficacy and experience of coil embolization in patients with pulmonary arteriovenous malformations(PAMV). Methods Seven patients (2 males and 5 females, age range from 11 to 52 years; mean age 31 years) were admitted including 4 single saccular, 2 multiple saccular, 1 diffuse capillary pulmonary arteriovenous malformations. Results Coil embolization of pulmonary arteries was successful in all 7 patients. The mean arterial oxygen saturation rate increased from 87% to 96% in patients with saccular PAMV. Transient chest pain occurred in a case of diffuse capillary PAMV during the procedure, after undergoing multiple coil embolization, the arterial oxygen saturation rate increased from 79% to 87%. All patients were followed up for 6 months to 5 years, arterial oxygen saturation declined slightly,and mild to moderate tricuspid regurgitation was found by echocardiography only in the patient with diffuse capillary PAMV.Conclusion Coil embolization is an effective and safe method of treatment for saccular PAMV. But it is only a palliative therapy for diffuse capillary PAMV.
