Randomized Controlled Trial
Effect of a Single Bolus of Erythropoietin on Renoprotection in Patients Undergoing Thoracic Aortic Surgery With Moderate Hypothermic Circulatory Arrest.
Acute kidney injury (AKI) is associated with high morbidity and mortality. Recombinant human erythropoietin has been shown to exert cytoprotection against ischemia. This study examined the effect of erythropoietin in preventing AKI during thoracic aortic surgery with moderate hypothermic circulatory arrest. ⋯ A single bolus administration of erythropoietin 500 IU·kg(-1) at anesthesia induction failed to provide renoprotection in patients who underwent thoracic aortic surgery with moderate hypothermic circulatory arrest. However, erythropoietin significantly reduced cardiac complications, and lowered the incidence of prolonged vasopressor dependence.

In the conventional ascending replacement for acute type A aortic dissection, the distal aortic anastomosis is frequently performed at the dissected site, and postoperative residual dissection in the arch and downstream aorta still occurs in most patients. We used open placement of a fenestrated stent graft during this operation. ⋯ An open fenestrated stent graft placement provided extensive primary repair of the thoracic aorta and a strong distal aortic stump during the conventional ascending aorta replacement for acute type A aortic dissection but did not increase the risk or technical difficulty of the operation.

Radiogenomic features are predictive of anaplastic lymphoma kinase (ALK) rearrangement in surgically resected non-small cell lung cancer (NSCLC). ⋯ ALK-rearranged lung cancer has characteristic clinical and imaging features compared with EGFR mutant or WT/WT cohorts. Our findings suggest that young age, lobulated margin, solid lesion, and hypoattenuation at contrast-enhanced CT scan are important predictors of ALK-rearranged lung cancer.

Bleeding may occur frequently during adult extracorporeal life support; however, there are no detailed investigations of bleeding events, red blood cell transfusion, and their impact on mortality. The purpose of our study was to characterize the incidence of bleeding and red blood cell transfusion during adult extracorporeal life support and examine the impact on mortality. ⋯ Bleeding and red blood cell transfusion occur frequently during adult extracorporeal life support, but only the amount of red blood cell transfusion is associated with inhospital mortality after controlling for confounding variables.

Intramural coronary arteries may complicate coronary artery transfer during the arterial switch operation. We sought to determine the long-term outcomes of 28 patients with intramural coronary arteries who underwent an arterial switch operation at a single institution. ⋯ Patients with intramural coronary arteries are not at increased risk of death or coronary reinterventions and have excellent late outcomes after the arterial switch operation.
