Tortuosity of the descending thoracic aorta: Normal values by age

PLoS ONE, 2019
Background Aging changes the aorta in length, tortuosity and diameter. This is relevant in thoracic endovascular aortic repair (TEVAR) and in the long term follow up. Methods and results Two groups of hundred patients < 65 years and hundred patients ≥ 65

Extra Anatomic Bypass of Coarctation of the Aorta in an Adolescent: Avoiding Spinal Cord Ischemia

MAMC Journal of Medical Sciences, 2015
Coarctation of the aorta in an adult patient often requires extra-anatomic bypass techniques. Posterior pericardial bypass technique is one among the various techniques that has been described where a Dacron conduit is anastomosed between the lateral ...

Iatrogenic dissection of the descending aorta: Conservative or endovascular treatment?

Annals of Cardiac Anaesthesia, 2016
Transcatheter aortic valve implantation (TAVI) is without any doubt a standard technique and the treatment of choice of severe aortic valve stenosis (AVS) in very high-operative risk patients.

Ultrasound compared to Computed Tomography in identifying thoracic aortic aneurysms in patients with Giant Cell Arteritis

Arthritis Care &Research, Accepted Article.
Objectives The objectives of this study were to evaluate the correlation and agreement between ultrasound and computed tomography (CT) in measuring ascending aorta diameter in patients with giant cell arteritis (GCA) and to investigate the development of new ascending aortic aneurysms in patients with newly diagnosed GCA. Methods To achieve the primary

Hybrid Approach of Aortic Diseases: Zone 1 Delivery and Volumetric Analysis on the Descending Aorta

Brazilian Journal of Cardiovascular Surgery
Introduction: Conventional techniques of surgical correction of arch and descending aortic diseases remains as high-risk procedures. Endovascular treatments of abdominal and descending thoracic aorta have lower surgical risk. Evolution of both techniques

A Superlubricated Magnetically Steerable Microcatheter with Integrated Optical and Fluidic Channels

Advanced Robotics Research, EarlyView.
A magnetically steerable microcatheter with integrated optical and fluidic channels is developed for multifunctional navigation in tortuous anatomical environments. A surface‐grafted hydrogel coating enables low‐friction actuation. The device demonstrates stable light and fluid delivery during magnetic manipulation, offering a compact platform for ...

Advanced Biomaterial Delivery of Hypoxia‐Conditioned Extracellular Vesicles (EVs) as a Therapeutic Platform for Traumatic Brain Injury

Advanced Science, EarlyView.
This research introduces a novel approach to enhance neuroregeneration following Traumatic Brain Injury (TBI). Extracellular Vesicles (EVs) are isolated from human neural progenitor cells under hypoxic conditions, leading to enhanced expression of neurogenic and angiogenic factors.

HMGB2 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through MTA2‐Driven Metabolic Reprogramming

Advanced Science, EarlyView.
In contrast to the adult mammalian heart, which lacks regenerative capacity, the neonatal heart retains a transient regenerative capacity. In this study, high mobility group box 2 (HMGB2) is identified as a crucial protein driving heart regeneration based on comprehensive analyses using quantitative proteomics with tandem mass tag (TMT) labelling, RNA ...

Direct access of ascending aorta for endograft delivery in the descending thoracic aorta

Journal of Vascular Surgery Cases and Innovative Techniques, 2020
First-line therapy for aneurysm, dissection, or rupture of the descending thoracic aorta is now by the endovascular approach. Retrograde insertion of the endograft, through access from the femoral arteries, is the preferred approach. This case presents a

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

Advanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...
