thromboembolic disorders, for exam 3 (apart of slide slow 1) Flashcards
(20 cards)
define thrombosis
- a local coagulation or blood clot that partially or fully obstructs blood flow
define embolus
- any detached, traveling mass (solid, liquid, or gaseous) in circulation capable of clogging arterial capillary beds
define thromboembolism
- a detached blood clot
define a thromboembolic Disorder
- a condition in which a
local blood clot (thrombus) inside one blood vessel is carried by the blood to block another vessel
define hemostasis?
- the stopping of blood flow
define coagulation
- the process of a blood clot being formed
what is the final stage of hemostasis?
- clot dissolution, lysis or fibrinolysis
- break down of clots and is normal
what do anticoagulants do?
- stop the coagulation cascade
what does fibrinolysis do?
- break down clots that have formed
- give w/ stroke
- results in fibrin degradation products (D - dimer)
what are the clinical manifestations of arterial thrombosis?
- pallor (pale)
- diminished or absent pulse
- cool temperature in the ischemic area
- burning / sharp pain or dumbness
- impaired function
- intermittent claudication (!!)
what is intermittent claudication?
- aching, cramping, tired, burning in the legs (!!) that comes and goes, typically occurs with walking and goes way with rest
- due to poor circulation of blood in the arteries of the legs
what is the biggest indication to arterial thrombosis?
- intermittent claudication
what is the clinical manifestations of VENOUS thrombosis?
- skin discoloration
- edema / swelling
- pulmonary embolism
- dull / achy pain, more common
- calf / groin tenderness
- neuralgia
- thrombophlebitis
what is neuralgia? & what disease is it apart of?
- intense, intermittent pain along the course of a nerve
- VENOUS thrombosis
what is thrombophlebitis? & what disease is it apart of?
- inflammation of the wall of the vein, associated with thrombosis, often in legs
- VENOUS thrombosis
what are interventions for thrombosis?
- oral or parenteral anticoagulant therapy
- drugs that block platelet activation/aggregation
- Anti embolic stockings or sequential compression devices
- ambulation asap
how do we treat thrombosis?
- once a thrombus has formed an anticoagulant therapy is initiated to prevent clot enlargement (!!)
- thrombolytic therapy (break up thrombus)
- or surgery to remove
what is acute arterial occlusion?
- absence of arterial circulation (emergency)
- could be result from thrombosis or mechanical compression
what are the classic signs of acute arterial occlusion? (6’s P’s)
- pallor = gray or white
- paresthesia (tingling)
- paralysis (dumb)
- pain
- polar (cool)
- pulseless (EMERGENCYYY)
what’s the treatment for Acute Arterial Occlusion
- Loosen tight dressing
– Cut cast
– Anticoagulant therapy
– Thrombolytic therapy
– Bypass surgery
– Embolectomy
– Amputation
