Case ReportA Single-Lung Transplantation Complicated by Torsion of the Donor Lung: Diagnosis by Intraoperative Transesophageal Echocardiography
Section snippets
Case Report
A 67-year-old male with interstitial lung disease secondary to scleroderma presented for left single-lung transplantation. Pertinent history included pulmonary artery hypertension with pulmonary artery pressures (PAPs) of 45/18 mmHg and a pulmonary vascular resistance of 3.7 wood units by cardiac catheterization. He required 3 L of oxygen at rest and 6 L with activity. His forced vital capacity was 53% of predicted, forced expiratory volume in 1 second of 57%, and forced expiratory volume in 1
Discussion
Lung torsion may be acute or insidious. Patients at higher risk include those undergoing lung resection or pulmonary ligament division or those who experience it secondary to trauma. Specifically regarding lung transplants, there is higher risk with a disproportionate chest cavity, donor lung size, or complete fissure of the donor lung. These factors are thought to increase lung mobility and, therefore, place the recipient at higher risk for torsion.3 There are fewer than 60 reported cases of
