Anomalies of the aortic arch in dogs: evaluation with the use of multidetector computed tomography angiography and proposal of an extended classification scheme

BMC Veterinary Research, 2021
Background Congenital anomalies of the aortic arch are important as they may be associated with vascular ring anomalies. The most common vascular ring anomaly in dogs is a persistent right aortic arch.

3D transparent technology displays the developmental patterns of ductus arteriosus morphology in chicken embryos before and after birth

Journal of Anatomy, EarlyView.
At the eighth week of human embryonic development, 3D transparent imaging enables clear visualization of the outflow tract's morphological features, revealing its anatomical components in detail. Abstract The ductus arteriosus (DA) is a critical fetal vascular structure that shunts blood from the pulmonary artery to the aorta, bypassing the non ...

Unusual cause of chest pain and dysphagia in a middle-aged woman with right aortic arch and aberrant left subclavian artery

Annals of Vascular Surgery - Brief Reports and Innovations
The aberrant subclavian artery is an uncommon congenital anomaly in the aortic arch, which may have a variety of presentations, including dysphagia, dyspnea, and chest pain, depending on the anatomical site of the aberrant vessel.

Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Non-invasive imaging of aberrant right subclavian artery pathologies and aberrant right vertebral artery

, 2009
Here, we review the CT and MR angiography findings of aberrant right subclavian and right vertebral arteries, with emphasis on the differences between these structures.

Subclavian Steal Phenomenon Associated With Vascular Ring in an Infant Who Had a Prenatally Diagnosed Right Aortic Arch With an Atretic Aberrant Left Subclavian Artery

, 2022
Vascular ring is a rare congenital anomaly in which the abnormal origin of the aorta or its branches and pulmonary arteries leads to encircling and compression of the trachea and esophagus.

Aberrant right subclavian artery: A review

JVS-Vascular Insights
Aberrant subclavian artery is a rare condition, with patients often present with dysphagia, dyspnea, back pain, or upper limb ischemia; occasionally, the condition is incidentally discovered as a mediastinal mass on chest radiography.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Pulseless Four Extremities: Atypically Located Coarctation With Concomitant Aberrant Right Subclavian Artery

, 2022
An unusual case of pulseless four extremities caused by atypically located critical coarctation of aorta with aberrant right subclavian artery in a 21 year old patient without any symptom for years such as syncope is presented.

Primary percutaneous coronary intervention in a patient with right internal mammary artery graft originating from arteria lusoria dextra [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2013
Introduction. Congenital anomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most ...
