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.
