Vitamin K Antagonist Reversal for Urgent Surgery Using 4-Factor Prothrombin Complex Concentrates: A Randomized Clinical Trial.

Importance: Millions of people take vitamin K antagonists (VKAs). Some people who need urgent surgical procedures require rapid VKA reversal to prevent excessive intraoperative bleeding.

Objective: To evaluate the hemostatic noninferiority of an investigational 4-factor prothrombin complex concentrate (4F-PCC) to a control 4F-PCC for rapid VKA reversal before urgent surgery.

Novel approach to treating a coronavirus disease 2019-positive patient with a complex arch and descending aneurysm and dissection for whom open surgery was prohibitive.

Ascending aortic and arch aneurysms are a challenging group of pathologies for surgeons. These typically require a complex open repair, including hypothermic circulatory arrest, and carry a high perioperative risk. The outcomes have been best when performed in centers with significant experience and expertise.

GORE TAG conformable thoracic stent graft for the treatment of descending aortic pathologies.

Endovascular repair of the descending thoracic aorta has gained widespread acceptance as a primary treatment modality for thoracic aortic disease due to its minimally invasive approach and improved survival rates. GORE TAG Conformable Thoracic Stent Graft was designed for descending thoracic aortic aneurysms, penetrating ulcers, aortic transections and type B aortic dissections, which are accepted indications for endovascular therapy. The aim of this review is to summarize the clinical literature, focusing mainly on the publications that came from manufacturer's pre-market and post-market studies.

Early Detection of Deep Venous Thrombosis in Trauma Patients.

Background This study was performed to determine whether trauma patients are at an increased risk of developing deep venous thrombosis (DVT) within the first 48 hours of hospitalization. Materials and methods A retrospective review was performed using a prospectively maintained database of patients admitted to a trauma center during a five-year time period. Patients hospitalized for greater than 48 hours who received a screening venous duplex for DVT were included in the study.
