25
Hemorrhagic Stroke
rupture of blood vessel in the brain
26
% of CVA from Embolus
70%
27
Plaque
Cholesterol can combine with fat, calcium, and other substances in the blood to form plaque
28
Ulcer of Plaque
Small divet created in a plaque build up
29
Platelets
blood cells that help form clots
30
Two ways a Carotid can embolize
- Necrotic plaque debris breaking off | - platelet deposition embolizing
31
Angiogram
X-ray test to take pictures of blood flow
32
Endarterectomy
Removal of stenotic material on the inside of the carotid artery
33
Angina Pectoris
Chest pain resulting from poor blood supply
34
Intestinal Angina
Abdominal pain resulting from poor blood supply
35
A-FIB
Atrial fibrillation, quivering heart beat, can cause blood clots
36
Signs of Acute Visceral Blockage
Intense Pain, Bowel Death
37
Signs of Chronic Visceral blockage
Intestinal Angina, Weight loss
38
Dialysis
Artificial replacement for the loss of kidney function, cleans waste from blood
39
HTN
Hypertension, High BP
40
Aldosterone
Hormone produced by the adrenal gland that helps in regulating BP
41
Renovascular HTN
HTN due to hormonal response of the kidneys from inadequate blood supply
42
Two causes of renovascular HTN
Atherosclerosis, FMD
43
FMD
Fibromuscular Displasia - progressive twisting of blood vessels
44
Angioplasty
opening of blocked artery to the heart using a catheter
45
intermittent claudication
LE pain due to exercise
46
Impotence
inability in a man to achieve an erection or orgasm
47
Leriche Syndrome - Signs & Symptoms
Claudication, Impotence, Decreased femoral pulses
48
Leriche Syndrome - Cause of
Aortoiliac atherosclerosis
49
Rest pain
Enduring LE pain, without exercise
50
Necrotic
cell death
51
Hydrostatic pressure
BP influenced by gravity
52
dry gangrene vs wet gangrene
Dry - local tissue death resulting in the tissue being sloughed off Wet - Infection of tissue due to untreated lack of blood supply, produces an oozing pus fluid, therefore "wet"
53
ulcer / ulceration
discontinuity or break in a body membrane
54
ABI's
Ankle Brachial Index
55
Anticoagulant
Meds given to help prevent blood clots, "blood thinners"
56
Heparin
Blood thinner
57
Warfarin-Coumadin
Blood thinner
58
Stent
tube inserted to keep a vessel open
59
US Prevalence of Renovascular HTN
5% of HTN diagnosis
60
US Prevalence of HTN
15% of adults
61
US Prevalence of HTN if Diastolic BP above 115
25%
62
US Prevalence in <5 years old
78%
63
3 Drug Rule for Renovascular HTN
3 drugs used to help manage RVHT until surgery can be performed
64
Paradoxical Embolization
An embolus that has been carried from the venous side to the arterial side
65
Chronic Venous insufficiency
inadequate blood flow to the veins, causing blood to pool in the legs
66
hemosiderin
Iron storage complex within cells
67
VENOUS ULCERS
Ulcers caused by poor circulation in the legs
