CV abbreviated Flashcards
3 arteries branch off aorta
- brachocephalic
- left common carotid
- left subclavian
4 arteries supply circle of willis
- anterior carotids
- posterior vertebral
What are the “six P’s” which indicate acute arterial occlusion?
- pain
- palor
- paralysis
- parasthesia
- poikilothermia
how are Arteriosclerosis and atherosclerosi different conditions
- Arteriosclerosis: stiffening or hardening of the artery walls
- Atherosclerosis: narrowing of the artery because of plaque build-up.
pseudoaneurysm
blood tears through walls and is contained by perivascular tissue
Describe “intermittent claudication” (functional ischemia).
pain in extremities during use, not during rest

knitted polyester
why is catheter used in embolectomy/thrombectomy?
2-7 fr fogarty catheter inserted proximal, advanced into vessel distally beyond obstruction, inflate balloon tip and cath withdrawn w/obstruction
Name three vascular clamps used for aortic occlusion.
- debakey
- fogarty
- satinsky
Name two shunts that may be used during carotid endarterectomy

- commercially made shunts (javid)
In which order are the artery clamps removed upon termination of the procedure?
- external
- common
- iliac
What instrument is used to extend the arteriotomy?
potts smith scissors
Describe the Brescia-Cimino fistula.
- Radial artery cephalic vein at wrist
- longest patency, lowest infection rate
What are the three most common and serious complications of vascular surgery?
