        Obstructive fibrinous pseudomembrane tracheitis after double-lumen tube intubation -a case report-

        Chua Jia-Hui,Sim Brenda Ling Hui,Theng Tina Koh Puay,Chew Sophia 대한마취통증의학회 2022 Korean Journal of Anesthesiology Vol.75 No.4

        Background: Obstructive fibrinous pseudomembrane tracheitis (OFPT) is a rare complication of endotracheal intubation. Case: We describe the case of a 73-year-old woman who underwent short-term intubation for video-assisted thoracoscopic surgery and developed an acute life-threatening stridor two days after extubation. The patient required an emergency tracheostomy to maintain airway patency and a microscopic direct laryngoscopy procedure was performed thereafter with removal of the obstructive pseudomembrane. Subsequently, the patient also suffered a non-ST-elevation myocardial infarction. The patient successfully recovered, and the tracheostomy was subsequently decannulated two months later. Histological examination revealed mucosal ulcerations and inflammatory changes.Conclusions: OFPT is an uncommon cause of life-threatening airway obstruction after extubation that is not often recognized immediately but can usually be treated with early bronchoscopic intervention or microscopic direct laryngoscopy.

        Cardiac evaluation for end-stage kidney disease patients on the transplant waitlist: a single-center cohort study

        Swati Vijayan,Quan Yao Ho,Choong Hou Koh,Ian Tatt Liew,Sobhana Thangaraju,Ningyan Wong,Yann Shan Keh,Zi Hui Sharel Ong,Jia Qin Tan,Khung Keong Yeo,Terrance Siang Jin Chua,Terence Kee 대한이식학회 2022 Korean Journal of Transplantation Vol.36 No.3

        Background: Cardiac evaluation before deceased donor kidney transplant (DDKT) remains a matter of debate. Data on Asian countries and countries with prolonged waiting times are lacking. This study aimed to assess the outcomes of patients referred for DDKT after a cardiac evaluation at an Asian tertiary transplant center. Methods: This single-center retrospective review analyzed patients who were referred for waitlist placement and underwent cardiac stress testing between January 2009 and December 2015. Patients with cardiac symptoms were excluded. The primary outcome was three-point major adverse cardiovascular events (MACE), a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death. Results: Of 468 patients referred for DDKT, 198 who underwent cardiac stress testing (myocardial perfusion studies in 159 patients and stress echocardiography in 39 patients) were analyzed. MACE occurred in 20.7% of the patients over a median follow-up of 4.6 years. Cardiac stress tests were positive for ischemia in 19.7% of the patients. Coronary angiography was performed in 63 patients, including 29 patients with diabetic kidney disease and negative cardiac stress tests. Significant coronary artery disease (CAD) was detected in 27 patients (42.8%), of whom 18 underwent revascularization. MACE was associated with significant CAD on coronary angiography in the multivariable analysis. Cardiac stress test results were not associated with MACE. Amongst diabetic patients who had negative cardiac stress tests, 37.9% had significant CAD on coronary angiography. Conclusions: The cardiovascular disease burden is significant amongst DDKT waitlist candidates. Pretransplant cardiac screening may identify patients with significant CAD at higher risk of MACE.
