A Case of Interventional Lung Assist Application in a Patient with Pulmonary Arteriovenous Malformation Complicating Massive Hemoptysis / 계명의대학술지

ABSTRACT

Percutaneous bronchial artery embolization and lung resection surgery have been effective for treatments of hemoptysis in patients with pulmonary arteriovenous malformation (PAVM). But, it has been little known about management for recurrent massive hemoptsis in patients with PAVM. It has been reported that Pumpless Extracoporeal Interventional Lung Assist (iLA) are effective for removal of hypercapnea in patient with acute respiratory failure. Here, we report a case of iLA support in a patient with PAVM complicating massive hemoptysis. A 38 year old man developed recurrent massive hemoptysis although interventions of bronchial artery embolization and lung resection surgery. The cause of recurrent hemoptysis was turned out PAVM. After a massive hemoptysis, the patient had severe hypercapnea and acidosis though mechanical ventilation and oxygenation. After iLA implantation, the hypercapnea was resolved and the clinical condition of the patient was improved, temporally. In conclusion, iLA may be a useful for bridge support in patients with prolonged massive hemoptysis.
