Sickle cell vaso-occlusion

Nov 02, 2020

Here inside this blood vessel, the circulation of red blood cells is obstructed by sickled red blood cells aggregating, sticking together, and leading to an event known as a vaso-occlusive crisis — a central characteristic of sickle cell disease (SCD)

As we zoom out, we are able to see more damage being done in other microvessels.

Sickled red blood cells promote inflammation, obstruct the vasculature, injure the endothelium, and may lead to ischemic damage in vital organs.

The pathophysiology of sickle cell disease

Jan 15, 2022

Segment from a 4-minute animation that explores the pathophysiology of sickle cell disease and the progressive, tissue-damaging effects of chronic hemolysis and anemia.

Our assignment: visually depict several key critical aspects of the SCD story, such as hemoglobin S (HbS) polymerization, red blood cell sickling and tethering, vaso-occlusion, and chronic hemolysis.

Sickled red blood cells promote inflammation, obstruct the vasculature, injure the endothelium, and may lead to ischemic damage in vital organs.
