“Vein thromboembolism”

is caused by a blood clot blocking a large artery in the lungs.

and may break into small pieces

to clog the capillaries in the lungs

Or it may fall off to fill the whole bar.

making it impossible to add oxygen to the blood

when the oxygen in the blood is very low

Cells far from the heart, such as hands and feet, may not receive enough oxygen.

damage the cells

It will be found that the tips of the hands and feet are getting darker.

If a blood clot forms in a deep vein

will cause leg swelling, soreness, pain, causing deterioration of the venous valve and venous wall

The blood clot broke into small pieces.

If the blood clot is larger

Some of them were broken into small pieces.

A blood clot that has broken into small pieces

or it may fall off the whole lump flowing to the heart

and to clog the arteries to the lungs

risk factor

Sitting for long periods of time,

such as driving a car or sitting in a plane for a long time

Elderly people who can't walk must use a wheelchair.

Causing the calf muscles to not be squeezed

The compression of the calf muscles helps the blood flow back to the heart.

There may be a risk of blood clots in the deep veins of the calf muscles.

Staying in bed for a long time,

such as staying in a hospital for a long time

or paralyzed patients

Causing the calf muscles to not move

It may be a risk factor for deep vein thrombosis in the leg.

Pregnancy

increases the pressure in the pelvic arteries and legs.

Women with a history of hereditary coagulation disorders

There is a higher risk of deep vein thrombosis in the legs during pregnancy.

The risk of deep vein thrombosis is associated with pregnancy.

It can last up to about 6 weeks after conception.

obese or overweight

This causes an increase in venous pressure in the pelvis and legs.

causing less movement than usual

Smoking

affects blood clotting and blood circulation.

This causes an increased risk of deep vein thrombosis.

trauma or surgery

presence of venous injury

or undergoing surgery

It can cause the blood flow to slow down.

It is a risk factor for the formation of blood clots in the veins.

Cancer

. Some cancers can increase the amount of a substance in the blood.

This is a risk factor for the formation of blood clots in the veins.

Including certain cancer treatments can increase the risk of developing deep vein thrombosis.

inflammatory bowel disease

Inflammatory bowel disease

may be a risk factor for deep vein thrombosis.

Heart failure (heart failure)

because people with heart failure lose the ability of their heart to pump blood.

Patients with reduced cardiac activity are at increased risk of developing deep vein thrombosis.

People with pacemakers

inserted into veins. Using or inserting these devices.

It irritates the walls of blood vessels and reduces blood flow.

This causes an increased risk of deep vein thrombosis.

contraceptive use

or hormone replacement

having a history of deep vein thrombosis

or thrombosis that has clogged the capillaries in the lungs before

having a family history of deep vein thrombosis

or thrombosis to block the capillaries within the lungs

People over 60 years old

very tall male

Next week, there will be an interesting story about the diagnosis of venous thromboembolism.

treatment and prevention

Let's wait to follow.
