Evolution of the wall shear stresses during the progressive enlargement of symmetric abdominal aortic aneurysms.

, 2006
The changes in the evolution of the spatial and temporal distribution of the wall shear stresses (WSS) and gradients of wall shear stresses (GWSS) at different stages of the enlargement of an abdominal aortic aneurysm (AAA) are important in understanding

Single‐Cell Profiling Identifies CLEC5A+ Macrophages as Key Drivers of Thoracic Aortic Aneurysm Via CCL5‐Mediated M1 Polarization

Journal of Clinical Laboratory Analysis, EarlyView.
Thoracic aortic aneurysm (TAA) is a life‐threatening cardiovascular disease with limited therapeutic options. Through single‐cell RNA sequencing of aortic tissues from healthy individuals and TAA patients (105,541 cells), we identified CLEC5A+macrophages as the predominant pathogenic cell population exhibiting the highest M1 polarization score. Machine

Sonographic Diagnosis of an Intercostal Artery Pseudoaneurysm: A Case Report and Literature Review

Journal of Clinical Ultrasound, EarlyView.
A 63‐year‐old male presented to the emergency department after being found unconscious during a welfare check. Following a prolonged three‐month hospital admission, the patient developed left flank pain. Spectral Doppler ultrasound revealed a large isoechoic lesion with layering echoes, and spectral Doppler demonstrated bidirectional flow.
