Is it possible for one's arteries to be clogged in places other than the brain or heart?

Yes, it’s possible to get a clog in the leg. These are dangerous, because they can become dislodged and travel to a vital area where they do serious damage.

Could it not happen pretty much anywhere in the veins or arteries?

Arterial plaque buildup is one of the causes of erectile disfunction.

It is common to have buildup in the aorta that runs from the heart through the center of the chest and abdomen. The aorta is the largest blood vessel in the body, so a ruptured abdominal aortic aneurysm can cause life-threatening bleeding.
Depending on the size of the aneurysm and how fast it’s growing, treatment varies from watchful waiting to emergency surgery.

Yes. It’s common in the legs.

@Hawaii_Jake You’re correct that clotting in the leg is dangerous for exactly the reason you give, but what you’re describing is a problem with the venous system. Arterial clogging from plaque is a different problem.

An aneurysm isn’t caused by a clog. An aneurysm is just a large protrusion/bulge caused by thinning of the arterial walls, while a blood clot is a cluster of blood caused by coagulation.

I had an ascending aortic aneurysm (in the upper arch of the aorta in the neck). They followed it for about 6 years before it got big enough that they did surgery. Why don’t they do surgery sooner rather than later? Because sometimes aneurysms don’t grow to the point of needing surgery.

Absolutely. When my dad had bypass surgery because his left main artery was very occluded they wanted to use a mammary artery, but that was too full of stuff too, so they used a leg vein. Years later one of his carotid arteries was very occluded and they had to tie it off completely.

The body can generate new artery growth, so as some block up, if the process is slow, there are new smaller tributaries that help carry the blood to the area. From what I understand some individuals are better at growing new tributaries than others. I guess it’s generic.

I don’t know a lot about the research happening around this, they want to understand why some people grow tributaries and others don’t. The research is also intertwined with cutting off arterial growth that feeds cancer cells.

Genetic not generic.
