Summary
Stroke affecting the artery of Percheron can cause coma by damaging the bilateral paramedian thalami. Emergency physicians must recognize this rare stroke to ensure timely treatment for comatose patients.
Area of Science:
- Neurology
- Neuroscience
- Emergency Medicine
Background:
- Coma is an uncommon stroke symptom.
- The artery of Percheron is a rare anatomical variant supplying the bilateral paramedian thalami.
Observation:
- A case of stroke affecting the artery of Percheron is presented.
- This stroke led to infarction in the bilateral paramedian thalami, resulting in coma.
Findings:
- The bilateral paramedian thalami play a crucial role in maintaining consciousness.
- Damage to these thalamic regions via a Percheron artery stroke can induce coma.
Implications:
- Prompt identification of atypical stroke syndromes like Percheron artery infarction is critical for emergency physicians.
- Recognizing this stroke in comatose patients is vital for appropriate therapeutic management and improving patient outcomes.

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

01:11Cardiac Output and Stroke Volume
4.9K
Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.

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...

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...
