Lung Transplantation for Chronic Humidifier Disinfectant-Associated Lung Injury / 대한구급학회지

In the spring of 2011, a cluster of lung injuries caused by humidifier disinfectant (HD) usage were reported in Korea. Many patients required mechanical ventilation, extracorporeal membrane oxygenation, and even lung transplantation (LTPL). However, the long-term course of HD-associated lung injury remains unclear because the majority of survivors recovered normal lung function. Here we report a 33-year-old woman who underwent LTPL approximately four years after severe HD-associated lung injury. The patient was initially admitted to the intensive care unit and was supported by a high-flow nasal cannula. Although she had been discharged, she was recurrently admitted to our hospital due to progressive lung fibrosis and a persistent decline in lung function. Finally, sequential double LTPL was successfully performed, and the patient's clinical and radiological findings showed significant improvement. Therefore, we conclude that LTPL can be a therapeutic option for patients with chronic inhalation injury.

Lung Transplantation in Acute Respiratory Distress Syndrome Caused by Influenza Pneumonia / 대한구급학회지

Severe acute respiratory distress syndrome (ARDS) is a life-threatening disease with a high mortality rate. Although many therapeutic trials have been performed for improving the mortality of severe ARDS, limited strategies have demonstrated better outcomes. Recently, advanced rescue therapies such as extracorporeal membrane oxygenation (ECMO) made it possible to consider lung transplantation (LTPL) in patients with ARDS, but data is insufficient. We report a 62-year-old man who underwent LTPL due to ARDS with no underlying lung disease. He was admitted to the hospital due to influenza A pneumonia-induced ARDS. Although he was supported by ECMO, he progressively deteriorated. We judged that his lungs were irreversibly damaged and decided he needed to undergo LTPL. Finally, bilateral sequential double-lung transplantation was successfully performed. He has since been alive for three years. Conclusively, we demonstrate that LTPL can be a therapeutic option in patients with severe ARDS refractory to conventional therapies.

Mitral Stenosis by Duran Ring in Children: Two cases report / 대한흉부외과학회지

Mitral stenosis was developed after Duran ring annuloplasty in two growing children during follow up period of 8 years and 5 years respectively, which may be due to pannus overgrowth and patient's growing. Only removal of pannus and prosthetic ring has resulted in complete relieving of Mitral stenosis. With time, even adult-sized annuloplasty ring may induce stenosis in growing children.

Truncus Arteriosus associated with Interrupted Aortic Arch / 대한흉부외과학회지

A 85-day-old infant was successfully operated on for truncus arteriosus (type I) with interrupted aortic arch (type A) using one-stage anterior approach without circulatory arrest. Aortic arch was reconstructed by direct anastomosis of ascending aorta and descending aorta with regional perfusion and continuity of right ventricle to pulmonary artery was established with Shelhigh(R) pulmonic conduit. The patient experienced left bronchus compression by descending aorta immediately postoperatively, which was improved with positional change and physiotherapy. The patient had reoperation due to stenosis of valved conduit at 13 months later. The patient is currently well under follow-up of 14 months from initial repair.
