Deep Vein Thrombosis Exam Verified
Questions With Answers
\.thrombosis definition
formation of a clotted mass of blood within an intact vessel of a non-interrupted CV system
\.difference between thrombosis and normal clotting
normal clot - vessel is lacerated and blood goes into surrounding tissue
thrombosis - pathologic, occurring inappropriately in an intact vessel
\.thrombus definition
clotted mass
\.thrombi composition determined by
location in cardiovascular system
\.white clots
thrombi on arterial side - fibrin and platelets
\.venous thrombi
closely resemble composition of clots formed in a test tube
\.Common location for venous clots
valves - blopod stagnates and clots behind valve cusps
\.hemorrhage definition
leakage of blood from a blood vessel - laceration or rupture
\.Types of smaller hemhorrages
petechiae (minute), purpura (up to 1 cm), ecchymoses (large blotchy spots)
\.hematoma
accumulation of a significant amount of blood within the tissue
\.when blood escapes into a serous cavity
, hemothorax, hemopericardium, hemoperitoneium
\.embolus
a solid, liquid, or gaseous mass carried through blood stream, causing interruption of flow
\.most emboli are derived from
thrombi
\.pulmonary embolism
clot from leg up through venous system into lungs
\.air emboli
open wound pressure sucks in air and moving clot = stroke
\.acute deep vein thrombosis
500,000 cases DVT per year, 50,000 deaths by PE
\.common sites of first occurence for DVT
soleal sinuses of the calf and in sinus of venous valve
\.95% of DVTs occur in
lower extremities
\.__% of cal vein thrombi progress to ______
20%, popliteal vein or higher
\.Proximal DVT
a.k.a, major DVT, involve popliteal vein or higher
\.As thrombi age, they
contract, filling less of the lumen
\.recanalization
thrombus opens up channels within them as they contract, mostly occurs within 90 days
\.more rapid lysis occurs,
more likley it is for valve function to be preserved
\.anywhere you have a clot is
