thrombus (redirected from obturating thrombus)

thrombus /throm·bus/ (throm´bus) pl. throm´bi   a stationary blood clot along the wall of a blood vessel, frequently causing vascular obstruction. Some authorities differentiate thrombus formation from simple coagulation or clot formation.

mural thrombus  one attached to the wall of the endocardium in a diseased area or to the aortic wall overlying an intimal lesion.

occluding thrombus , occlusive thrombus one that occupies the entire lumen of a vessel and obstructs blood flow.

parietal thrombus  one attached to a vessel or heart wall.

thrombus

an aggregation of blood factors, primarily platelets and fibrin with entrapment of cellular elements, frequently causing vascular obstruction at the point of its formation. The lesion and the syndrome produced by the thrombus depend on its location, e.g. pulmonary artery.

mural thrombus

one attached to the wall of the endocardium in a diseased area.

obturating thrombus

one which continues to grow distal to its site of attachment and the free end trails downstream with the current of blood.

occluding thrombus

one that occupies the entire lumen of a vessel and obstructs blood flow.

parietal thrombus

one attached to a vessel or heart wall.

saddle thrombus

one formed at the terminal aorta and extending into the iliac arteries. Occurs most commonly in cats with arterial thromboembolism.

thrombus

Hematology An intravascular blood clot formed in vivo from fibrin thread accumulation around a platelet plug. See Deep vein thrombosis, Pulmonary thromboembolism.

Patient discussion about obturating thrombus.

Q. How can I prevent blood clots? I am 45 years old and am supposed to go on a business trip overseas. The flight itself is 12 hours long and then I have to continue traveling by bus. Could this cause me to have blood clots? If so, how can I prevent it?

A. Sitting or laying in one position for a long period of time can increase the risk of developing DVT- deep vein thrombosis. Here are some methods to prevent it:
Exercise your calf and foot muscles regularly:
Every half hour or so, bend and straighten your legs, feet and toes when you are seated.
Press the balls of your feet down hard against the floor or foot-rest every so often. This helps to increase the blood flow in your legs
Take a walk up and down the aisle every hour or so, when the aircraft crew say it is safe to do so.
If you are allowed, get off the plane and walk about if the plane stops for refueling.
Consider buying a leg exerciser for the journey.
Drink plenty of water (to avoid dehydration).
Do not drink too much alcohol. (Alcohol can cause dehydration and immobility.)
Do not take sleeping tablets, which cause immobility.
Consider wearing compression stockings.
Some people at high risk may also be advised to take anticoagulant medication by their Dr.
