chronic venous insuff and varicose veins Flashcards
1
Q
what are 2 venous systems in leg and what veins are in them
A
superfical - greater saph - short saph deep - correspond to As - femoral vein - popliteal and peroneal perforators connect the 2 systems
2
Q
what are 2 valve types and what is patho of them
A
- venous valves
- bi-leaflet valves
blood can reflux if they are damaged
3
Q
4 reasons for valves to stop working
A
- clots
- vein dilatation
- gene
- idio
end result is vein dialtation of superficial veins - varicose veines
4
Q
7 risks for varicose veins
A
- F
- preg
- prolonged standing
- obesity
- age
- trauma
- superfical thrombophlebitis
5
Q
Sx of varcose
A
- pain
- burning
- itch
- swelling
- aching
Sx NOT correlated with size of vein
6
Q
how to diagnose
A
get an US
7
Q
Tx options
A
- nothing
- compression stokings
- injection sclerotherapy
- foam sclerotherapy
- surgical stripping
- endovenous laser ablation
- endovenous RF ablation
8
Q
what are compressio stokings
A
- higher P at bottom
- do not get rid of veins
- may slpw progression
9
Q
what is injection sclerotherapy
A
- inflames vein wall and they stick together
- not good for large veins
- does not solve GSV reflux
10
Q
what is foam sclerotherapy
A
- makes foam in the lumen
- better for large veins
11
Q
what is surgical stripping
A
- remove GSV
- good for ablating GSV, but bruising and discomfort
12
Q
what is laser and RF ablation
A
- melt the vein from the inside
- less pain and faster recovery
- similar outcome to each other
13
Q
what is abulatory venous HT
A
- still valve problems
- get large P in the leg
- usually due to old clots
14
Q
what are risk factors for deep system disease
A
- older
- F
- DVT
- genes
- obesity
- prolonged standing
15
Q
what is presentation
A
- chronic
- swelling
- ## brown skin and ulcer on medial malleoslus
