Vascular Flashcards
When not to give compression stockings
ABPI < 0.8 (arterial disease)
6 Ps of critical ischaemia
Pulseless Perishingly cold Paraesthesia Paralysis Pain Palor
Male smoker with inflammation and occlusion of medium sized arteries
Buerger’s disease
worse prognosis than atherosclerosis - must give up smoking or risk irreversible damage to arterial tree
carotid endarterectomy indications
symptomatic + 70-99% stenosis
critical limb ischaemia triad
Ischemic rest pain
arterial insufficiency ulcers
gangrene
ABPI critical limb ischaemia
<0.3
Timings of acute limb ischaemia
0-4 h: white, painful, sensory-motor deficit
4-12 h: mottled rash that blanches - partly salvageable
12+ h: non blanching, fixed, mottling - unsalvageable (urgent amputation/palliation)
Abdominal pain after eating
mesenteric angina
Classic signs of arterial ulcer
pain at rest
punched out
poor peripheral pulses
deep
Classic signs of venous ulcer
gaiter area
preceding skin changes - venous eczema, lipodermatosclerosis, haemosiderin deposits
shallow
AAA classification
permanent localised dilatation >50% original diameter
true aneurysm
all layers affected
atherosclerosis most common cause
trauma + pulsatile mass
false aneurysm
when is AAA repair considered
> 5.5cm
varicose vein intervention
u/s guided foam sclerotherapy
most common distal aneurysm
popliteal
aortic dissection types
A - ascending aorta affected
B - starts at origin of subclavian
tx of type A dissection
surgical - aortic replacement using cardiopulmonary bypass
tx of type B dissection
medical tx of HTN
tearing chest pain radiating to back + hemiplegia
aortic dissection
secondary venous insufficiency causes
DVT, pregnancy, neoplasm
complication of lymphoedema
recurrent cellulitis
Recent aortic surgery + brisk GI bleed + malaria + hypotension
aortoenteric fistula
rx - emergency surgery
poor prognosis ):
complication of cervical rib
thoracic outlet syndrome
