vascular and lymphatic Flashcards
Embolization therapy
occluding a vessel
to treat inappropriate blood flow, such as AVMs
Transcatheter Thrombolysis
break up the clot in occluded vessel
Thrombectomy
lyse or remove an extensive thrombus in the lower extremity
Immediately restores perfusion but invasive
Peripheral Vascular Bypass Grafting used to
claudications and critical ischemia ,
restore blood flow
3 PT considerations with Peripheral Vascular Bypass Grafting
*** 24-48 hrs to recover hemodynamic stability (VS closely monitored)
**Often no WB restriction (but always check)
**Keep LE extended and elevated when possible
Endarterectomy used for
localized occlusive vascular disease
remove plaque
vascular pain source cause
LE pain bc of ischemia
Cause: lack of blood flow
Neurogenic claudication
Nerve issue , impingement in spine
Cause: dependent position ( more flexed= more irritated)
ARTERIOGRAPHY/ contrast angiography what is it
Dye into blood vessel to see perfusion
ARTERIOGRAPHY/ contrast angiography PT considerations
what to monitor , how long on bed rest,
BUN and creatinine monitored
Frequent vital sign monitoring, with pulse assessments.
Bed rest for 4 to 8 hours.
what is the underlying cause of most MIs, many CVAs and ischemic gangrene
Atherosclerosis
Necrotizing blood vessels in upper respiratory tract, lungs, and kidneys
Pulmonary S/S mimic pneumonia
WHAT CONDITION
Wegener’s granulomatosis
Inflammation, necrosis, narrowing of arteries
WHAT CONDITION
Systemic vasculitis
pulmonary embolism
origin
mismatch
Most originate from LEs
Acute V/Q mismatch
Embolectomy, IVC filter
Chronic venous insufficiency/post-phlebitic syndrome
end result of recurring DVTs
Polycythemia
Excessive RBCs
issue in bone marrow
Disseminated intravascular coagulation
Massive clotting cascade that produces both clotting and hemorrhaging
stages of lymphedema visual
stage 0= subclinical
stage 1 = early buildup of fluid with high protein count, some swelling may be present
stage 2 = irreversible, interventions start not working, pitting is present
stage 3 = lot going on here
stemmers sign
pull skin and release (normal) , + = skin cant be pinched and lifted ( too much swelling)
Negative pressure gradient lymph mobility
how diaphramatic and MLD help
Lymph flows from high pressured to low pressured areas.
MLD: reduces trunk pressure thus allowing fluid to flow out of extremity.
diaphragmatic breathing: pulling fluid out of extremities
