Summary
A bovine arch, an aortic arch variant, is linked to increased vascular risks. This report details the first case of a young patient experiencing a symptomatic aortic arch floating thrombus alongside this anatomical variation.
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Anatomical Variations
Background:
- The bovine arch is an anatomical variation of the aortic arch where the left common carotid artery and brachiocephalic trunk share a single origin.
- Patients with a bovine arch exhibit a higher prevalence of vascular pathologies, including aneurysms, dissections, and strokes.
- Aortic arch pathologies can lead to significant morbidity and mortality, necessitating a thorough understanding of associated risk factors.
Purpose of the Study:
- To report the first case of a symptomatic aortic arch floating thrombus in a young patient with a bovine arch.
- To highlight the potential association between the bovine arch variant and the development of aortic thrombi.
- To increase awareness among clinicians regarding the clinical implications of the bovine arch.
Main Methods:
- Case report of a young patient presenting with symptoms suggestive of embolic events.
- Diagnostic imaging including computed tomography angiography (CTA) to delineate aortic arch anatomy and identify thrombus.
- Review of existing literature on bovine arch prevalence and associated vascular conditions.
Main Results:
- The patient was diagnosed with a symptomatic floating thrombus originating from the aortic arch.
- The underlying anatomy was confirmed as a bovine arch, with the left common carotid artery and brachiocephalic trunk sharing a common origin.
- This represents the first documented instance of a symptomatic aortic arch floating thrombus associated with a bovine arch in a young individual.
Conclusions:
- The bovine arch may be an underrecognized risk factor for aortic arch pathologies, including floating thrombus formation.
- This case underscores the importance of considering anatomical variants in the evaluation of embolic phenomena.
- Further research is warranted to elucidate the precise relationship between the bovine arch and aortic thrombus development.

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

46
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
