Possibilities of noninvasive radial diagnostics were studied in examination of 27 patients with dissecting aneurysms of the aorta. Classical X-ray examinations of chest organs have diagnosed aorta wall dissection in 2 of 24 patients. In 19 patients the diagnosis of aorta dissection was suspected. The ultrasound examination gave correct diagnosis in 3 of 4 patients examined. The non-contrast computed tomography has revealed dissecting aneurysms in 8 of 24 patients, an investigation with the intravenous injection of the contrast substance--in 13 of 15 patients. The diagnosis was based upon the detection of 2 canals of the aorta with the dissected intima between them, thrombosis of the false aorta canal and accumulation of the liquid in the pleura and pericardium cavity. When planning operative procedures it becomes necessary to perform aortography.

A preliminary ex vivo diffusion tensor imaging study of distinct aortic morphologies.

Trinity Centre for Biomedical Engineering, Trinity Biomedical Sciences Institute, Trinity College Dublin, Dublin, Ireland.
Changes in the microstructure of the aortic wall precede the progression of various aortic pathologies, including aneurysms and dissection. Current clinical decisions with regards to surgical planning and/or radiological intervention are guided by geometric features, such as aortic diameter, since clinical imaging lacks tissue microstructural information. The aim of this proof-of-concept work is to investigate a non-invasive imaging method, diffusion tensor imaging (DTI), in ex vivo aortic tissue to gain insights into the microstructure.

Background: The aim of this study was to investigate whether the hybrid technique yields superior outcomes in comparison with the total arch replacement combined with frozen elephant trunk (TAR + FET) for acute aortic dissection (AAD) involving the aortic arch.
Methods: This retrospective cohort study using propensity-score matching included patients with AAD involving the aortic arch admitted to Nanjing First Hospital and Shanghai General Hospital from January 2015 to June 2020. The in-hospital and mid-term outcomes were compared between patients who received hybrid treatment (n = 136) and those who received TAR + FET (n = 415).
Characteristics of transition to turbulence in a healthy thoracic aorta using large eddy simulation.

University of Ulsan, 93 Daehak-ro, Nam-gu, Ulsan, 680-749, Republic of Korea.
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.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

Objectives: Previous analyses of the volume-outcome relationship have focused on short-term outcomes such as early mortality. The current study aims to update a novel statistical methodology, facilitating the evaluation of the relation between procedural volume and time-to-event outcomes such as long-term survival, using surgery for acute type A aortic dissection as an illustrative example.
Methods: This study employed an existing dataset of type A dissection outcomes, retrieved from literature.
