Insights

Atherosclerotic plaques in the aorta can cause thromboembolism. This case highlights a large aortic plaque mistaken for a thrombus, successfully treated with surgical resection, preventing further embolic events.

Area of Science:

  • Cardiovascular Medicine
  • Vascular Surgery
  • Diagnostic Imaging

Background:

  • Thromboembolism poses a significant health burden, with aortic atherosclerotic plaques being a notable, often overlooked, source.
  • Atherosclerosis is a prevalent condition, increasing the risk of cardiovascular events.

Observation:

  • A 63-year-old woman with hypertension and diabetes presented with refractory exertional chest pain.
  • Aortography revealed a mobile mass in the aortic arch, initially suspected to be a thrombus.
  • Advanced imaging confirmed a large, mobile mass within the aorta, associated with widespread atherosclerotic changes.

Findings:

  • The intra-aortic mass was identified as a large atherosclerotic plaque, not a thrombus.
  • The patient underwent successful coronary artery bypass grafting for severe coronary artery disease.
  • The aortic plaque was resected during the same surgical session, with no immediate complications.

Implications:

  • This case underscores the importance of considering aortic atherosclerotic plaques as a source of thromboembolism.
  • Accurate diagnosis and timely surgical intervention for mobile aortic plaques can prevent embolic complications.
  • Effective management of cardiovascular risk factors is crucial in patients with advanced atherosclerosis.

The Arch of Aorta01:10

The Arch of Aorta

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.
Encircling the heart, the coronary arteries form a ring-like structure before...

Sign Convention01:30

Sign Convention

When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

Finding the Center of Gravity01:03

Finding the Center of Gravity

The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Enolate Mechanism Conventions01:15

Enolate Mechanism Conventions

When a carbonyl compound is treated with a strong base, the α position gets deprotonated to give a resonance-stabilized intermediate called an enolate. Enolates are ambident nucleophiles because they possess two nucleophilic sites that can attack an electrophile owing to the delocalization of the negative charge between the α carbon and oxygen atoms. When the oxygen atom attacks an electrophile, it is called O-attack, whereas electrophilic attack via the α carbon is known as...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
