Resection of a dissecting aneurysm of the descending thoracic aorta (Type III) was accomplished in a uremic patient on hemodialysis with reconstruction of blood flow through extrathoracic bilateral axillary-subclavian-iliac Dacron grafts. Review of the literature revealed no similar operation reported before. Other potential uses for this operation, such as infected aortic grafts and resections of the arch and descending thoracic aorta in high-risk patients, are discussed. Despite complete rehabilitation of this patient 10 months after operation, the application of this procedure must await longer term follow-up. The operative procedure described thus far was applied only in one patient and should be considered only in special circumstances, as discussed.

Descending necrotizing mediastinitis (DNM) is a rare and potentially life-threatening condition characterized by the rapid spread of infection within the mediastinum. This severe form of mediastinitis poses a significant challenge to clinicians due to its aggressive nature and potential for rapid deterioration. In this case report, we present a challenging case of descending necrotizing mediastinitis in a 39-year-old patient with persistent pyrexia and an extended hospital stay in the intensive care unit (ICU), cardiothoracic unit (CTU), and surgical intensive care unit (SICU).

Rationale And Objectives: Cardiovascular toxicity is a well-known complication of thoracic radiation therapy (RT), leading to increased morbidity and mortality, but existing techniques to predict cardiovascular toxicity have limitations. Predictive biomarkers of cardiovascular toxicity may help to maximize patient outcomes.
Methods: The machine learning optimal biomarker (OBM) method was employed to predict development of cardiotoxicity (based on serial echocardiographic measurements of left ventricular ejection fraction and longitudinal strain) from computed tomography (CT) images in patients with thoracic malignancy undergoing RT.

Objective: This systematic review and meta-analysis aimed to evaluate and compare the efficacy of endovascular versus open repair for the treatment of patients with descending thoracic aortic aneurysm (DTAA).
Methods: A systematic search of the PubMed, Embase, and Cochrane Library databases for relevant studies was performed. Outcome data, including postoperative mortality and morbidity, operative details, all-cause survival, freedom from aortic-related survival and freedom from aortic-related re-intervention, were independently extracted by two authors in a standardized way.

Aims: To assess the reproducibility of 4D-Flow cardiac magnetic resonance (CMR) parameters in the descending thoracic aorta-DTAo-(regurgitant fraction [RF], end-diastolic reverse flow [EDRF], and holodiastolic flow reversal [HDR]), and the relationship with RF in the sinotubular junction (STJ), and the left ventricular end-diastolic volume index (LVEDVI) in patients with chronic aortic regurgitation (AR).
Methods And Results: A descriptive study of these variables was conducted. A receiver operating characteristic curve was used to determine the optimal cut-off point.

This study employed large eddy simulation (LES) with the wall-adapting local eddy-viscosity (WALE) model to investigate transitional flow characteristics in an idealized model of a healthy thoracic aorta. The OpenFOAM solver pimpleFoam was used to simulate blood flow as an incompressible Newtonian fluid, with the aortic walls treated as rigid boundaries. Simulations were conducted for 30 cardiac cycles and ensemble averaging was employed to ensure statistically reliable results.
