Insights

Severe COVID-19 can lead to rare posterior circulation strokes months later. This case highlights the risk of thromboembolic events as a delayed complication of COVID-19.

Area of Science:

  • Neurology
  • Cardiology
  • Infectious Diseases

Background:

  • COVID-19 is associated with thrombotic complications.
  • Posterior circulation strokes are uncommon sequelae.

Observation:

  • A previously healthy 39-year-old male developed right-sided homonymous hemianopia three months after severe COVID-19.
  • Elevated inflammatory markers and D-dimer levels were noted.

Findings:

  • Imaging confirmed an acute left occipital infarct, indicating a posterior circulation stroke.
  • This rare post-COVID-19 event suggests a potential link between severe infection and delayed cerebrovascular complications.

Implications:

  • Highlights the need to consider thromboembolic events as late complications in severe COVID-19 survivors.
  • Emphasizes recognizing stroke symptoms in patients with a history of severe COVID-19.
  • Discusses pathophysiology and anticoagulation strategies for COVID-19-related thrombotic events.

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...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

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...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Venous Return

The circulatory system plays a crucial role in ensuring the optimal functioning of the human body. One of its critical components is venous return - the process that completes the blood circulation cycle. This article will delve into the concept of venous return, how it works, and its significance to our health.
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...

Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
