Summary
Artery of Percheron (AOP) occlusion causes rare strokes in the thalamus. This case highlights cardioembolic AOP infarction in a young woman with mitral stenosis, detailing its unique clinical and imaging features.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Artery of Percheron (AOP) occlusion is a rare cause of ischemic stroke.
- It typically results in bilateral paramedian thalamic infarcts, potentially with mesencephalic involvement.
- Clinical presentation includes altered mental status, hypersomnolence, speech and memory deficits, and ocular movement disorders.
Observation:
- A case of cardioembolic AOP infarction in a 37-year-old woman is presented.
- The patient had a history of rheumatic mitral valvular stenosis.
- Neuroimaging revealed characteristic bilateral paramedian thalamic infarcts.
Findings:
- The occlusion led to a specific pattern of ischemic stroke in the thalamus.
- Cardioembolism was identified as the etiology in this young patient.
- The case underscores the importance of considering AOP infarction in the differential diagnosis of thalamic strokes.
Implications:
- This case expands the understanding of AOP infarction presentations.
- It emphasizes the link between valvular heart disease and embolic stroke.
- Highlights the diagnostic value of neuroimaging in identifying rare stroke etiologies.

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.

01:30Peripheral Artery Disease I: Introduction
549
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

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 subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
