Summary
Peripheral artery disease, an extra-cardiac manifestation of atherosclerosis, can affect aortic arch arteries. This case highlights an uncommon synchronous athero-thrombotic obliteration of major arteries in a hypertensive patient.
Area of Science:
- Cardiovascular Medicine
- Vascular Surgery
- Atherosclerosis Research
Background:
- Peripheral artery disease (PAD) is recognized as an extra-cardiac manifestation of atherosclerosis.
- Atherosclerosis commonly presents as lower limb ischemia but can affect other arterial systems.
- Atherosclerotic mechanisms can lead to stenosis or obliteration of aortic arch arteries.
Purpose of the Study:
- To report an uncommon case of synchronous athero-thrombotic obliteration of the right brachio-cephalic and left subclavian arteries.
- To illustrate a rare presentation of atherosclerosis involving the aortic arch vessels.
Main Methods:
- Case report presentation.
- Clinical and diagnostic evaluation of a patient with acute arterial occlusion.
Main Results:
- The patient presented with acute, 6-hour symptomatic athero-thrombotic obliteration of the right brachio-cephalic and left subclavian arteries.
- The underlying cause was identified as atherosclerosis in a hypertensive male.
Conclusions:
- Synchronous athero-thrombotic obliteration of major aortic arch arteries is a rare but critical presentation.
- Atherosclerosis can manifest acutely and severely in the aortic arch vessels, mimicking other vascular emergencies.

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...

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)...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
