Objectives: The Stanford classification categorizes aortic dissection based on ascending aortic involvement, whereas the newer Society for Vascular Surgery/Society of Thoracic Surgeons (SVS/STS) classification emphasizes tear location. Thus, traditional Stanford type A dissection may be an SVS/STS type A dissection or SVS/STS type B0 dissection. We evaluated the impact of SVS/STS classification on perioperative characteristics and outcomes after acute Stanford type A dissection repair.

Objective: During open descending thoracic and thoracoabdominal aortic aneurysm (DTAA/TAAA) repair, we used a routine T8-T12 intercostal artery (ICA) reattachment strategy from July 2004 to June 2009 and after 2017, we used a selective ICA reattachment strategy (reattaching T8-T12 ICAs only when neuromonitor signals were lost) from July 2009 to 2016. This study reviewed our nearly 2-decade experience to assess the impact of 2 ICA reattachment strategies on spinal cord injury (SCI).

Methods: All open DTAA/TAAA repairs performed from July 2004 to June 2022 were included, except for cases without intraoperative cerebral spinal fluid drainage.

Objective: The purpose of this study was to apply contemporary consensus criteria developed by the Society for Cardiovascular Pathology and the Association for European Cardiovascular Pathology to the evaluation of aortic pathology, with the expectation that the additional pathologic information may enhance the understanding and management of aortic diseases.

Methods: A scoring system was applied to ascending aortic specimens from 42 patients with heritable thoracic aortic disease and known genetic variations and from 86 patients from a single year, including patients with known genetic variations (n = 12) and patients with sporadic disease (n = 74).

Results: The various types of lesions of medial degeneration and the overall severity of medial degeneration overlapped considerably between those patients with heritable disease and those with sporadic disease; however, patients with heritable thoracic aortic disease had significantly more overall medial degeneration (P = .

Background: Trauma patients exhibit a multifactorial hypercoagulable state and have increased risk of venous thromboembolism (VTE). Despite early and aggressive chemoprophylaxis (CP) with various heparin compounds ("standard" CP; sCP), VTE rates remain high. In high-quality studies, aspirin has been shown to decrease VTE in postoperative elective surgical and orthopedic trauma patients.

Background: The objective of our present effort was to use an international blunt thoracic aortic injury (BTAI) registry to create a prediction model identifying important preoperative and intraoperative factors associated with postoperative mortality, and to develop and validate a simple risk prediction tool that could assist with patient selection and risk stratification in this patient population.

Methods: For the purpose of the present study, all patients undergoing thoracic endovascular aortic repair (TEVAR) for BTAI and registered in the Aortic Trauma Foundation (ATF) database from January 2016 as of June 2022 were identified. Patients undergoing medical management or open repair were excluded.

The use of a placebo has been considered the best method for controlling bias in a prospective randomized clinical trial and provides the most rigorous test of treatment efficacy for evaluating a medical therapy. Placebos commonly produce clinically important effects particularly in studies where the primary outcomes are subjective. Yet the potential beneficial or harmful effects of placebos are often not addressed in designing a clinical trial, calculating the sample size, seeking consent, or interpreting clinical trial results.
