Abstract

The purpose was to evaluate the clinical and radiological long-term results of embolization of pulmonary arteriovenous malformations (PAVMs) and to assess the quality of life after treatment. A clinical follow-up was undertaken after 67 months (mean) in 35 consecutive patients with 106 PAVMs. Outcome parameters at follow-up were PaO2 and patients’ satisfaction. During follow-up, the patients had a clinical examination, measurement of arterial blood gases, chest X-ray, and contrast echocardiography performed and were asked to fill in a questionnaire exploring experience of the treatment and subjective effect of treatment on physical and social functioning. A significant rise in oxygenation of the blood after embolization was measured. In 77% of the patients symptoms improved, and 71% felt better performance. In eight patients, one of the PAVMs was found insufficiently embolized or recanalized at follow-up angiography and therefore were re-embolized. Endovascular embolization for PAVMs is effective. Clinical parameters and quality of life improved significantly. Regular clinical controls after therapy are necessary to discover insufficiently embolized, recanalized or new PAVMs.
