Purpose: To review the results of endovascular treatment of acute aortic dissections with domestic stent-grafts at a single center.
Methods: Data from all 51 patients who presented with acute aortic dissections (ADs, Stanford B type) between April 2004 and May 2009 and underwent endovascular interventions with domestic stent grafts were retrospectively reviewed. Of these patients 50 had primary ADs and 1 had a traumatic AD. All patients were followed up for from 1 to 48 months (average, 15.11 ± 10.93 months).
Results: There was no strut failure or surgical conversion in any of the patients. Intraoperative angiography documented the complete seal of the primary entry. Two deaths occurred during hospitalization. One patient died due to aortic rupture 24 h after the procedure, and the other died of myocardial infarction 3 days later. Two patients (4.1%) died during the follow-up period. A Kaplan-Meier analysis revealed a 4-year survival rate of 92.16%.
Conclusions: Endovascular treatment for acute Stanford B-type ADs with domestic stent grafts is both safe and effective, while also demonstrating an acceptable survival rate and mid-term clinical outcomes.

Department of Cardiovascular Surgery, Fujian Medical University Union Hospital, Fuzhou, PR China.
Background: This study aimed to investigate the demographics and to evaluate long-term outcomes of acute type A aortic dissection (ATAAD) in surgically treated patients ≤40 years in China.
Methods: This study included patients aged ≤40 with ATAAD who underwent surgical treatment at our institution between 2015 and 2019. The patients were categorized into groups according to heritable thoracic aortic disease (HTAD) presence or absence.

Department of Anesthesiology and Operation, The First Hospital of Lanzhou University, Lanzhou, Gansu, China.
Objective: We aimed to explore the application value of unsupervised machine learning in identifying acute gastrointestinal injury (AGI) after extracorporeal circulation for acute type A aortic dissection (ATAAD).
Methods: Patients who underwent extracorporeal circulation for ATAAD at the First Hospital of Lanzhou University from January 2016 to January 2021 were included. Unsupervised machine learning algorithm was used to stratify patients into different phenogroups according to the similarity of their clinical features and laboratory test results.

Introduction And Objectives: This retrospective study aimed to develop a nomogram to predict the risk of postoperative acute respiratory distress syndrome (ARDS) in patients with Stanford type A acute aortic dissection.
Methods: The study included patients who underwent surgical repair for Stanford type A acute aortic dissection between January 2020 and December 2023. Demographic data, surgical details, intraoperative information, and postoperative outcomes were collected.
