Delayed Presentation Injury of Descending Aorta and Bronchus Due to Sewing Needle Penetration: A Case Report.

We report a case of a tracheal foreign body caused by a sewing needle. After about four months, the patient showed delayed dry cough and hemoptysis. The sewing needle that pierced the tracheal wall damaged the aorta, and we performed endovascular stenting to prevent arterial bleeding and removed it under a bronchoscope.

Integrated analysis of immunocyte infiltration and differential gene expression in tricuspid aortic valve-associated thoracic aortic aneurysms.

Background: Progressive dilatation is responsible for significant mortality and morbidity in patients with thoracic aortic aneurysms (TAAs). Studies have shown that the development and progression of TAAs are closely related to immune regulatory pathways and genes. Therefore, it is important to understand the immune regulatory mechanisms and biomarkers of TAA dilatation.

"Aorta-clamp" technique for surgical repair of acute type A aortic dissection-5 min circulatory arrest at 30 °C.

Background: Deep hypothermic circulatory arrest (HCA), which causes perioperative complications, is the foundation of surgical treatment for acute type A aortic dissection (AAAD). To extensively replace the dissected aorta and avoid the negative impacts of HCA, we developed an "aorta-clamp" technique and examined its efficacy in repairing AAAD.

Methods: From November 2014 to August 2016, we recruited 59 consecutive patients (51.
