Flashcards in Venous Disease Deck (12):
1

what is venous disease in the deep veins?

deep vein insufficiency

2

what is venous disease in the superficial veins?

varicose veins

3

what does venous disease result in?

valvular incompetence

4

what are varicose veins?

abnormally dilated and lengthened superficial veins
primary (idiopathic) or secondary

5

primary varicose veins

twice more common in women with pregnancy accentuating symptoms
likely to be due to primary superficial valve defect with familial elements
no deep venous incompetence

6

secondary varicose veins

superficial varicosities occurs secondary to deep venous incompetence
- previous DVT: valves remain incompetent
- raised systemic venous pressure: due to compression (pelvic tumour, pregnancy), AV fistula or severe tricuspid incompetence

7

symptoms of varicose veins

unsightly appearance
tiredness
aching
throbbing
oedema of ankles, particularly on standing for long periods
itching and nocturnal cramps
signs of deep venous insufficiency: haemosiderosis, eczema, lipodermatosclerosis

8

when does deep venous insufficiency (postphelbitic limb) occur?

valves of deep venous system are incompetent
calf pump can no longer efficiently return blood to thoracic cavity

9

types of deep venous insufficiency

primary - congenital absence of valves
secondary - DVT causing valvular damage or AVF raising venous pressure

10

features of deep venous insufficiency

lower limb aching pain/discomfort
oedema of the lower leg
superficial varicose veins
- raised central pressure causes perforator incompetence
haemosiderin deposition in gaiter area
eczema particularly over the pigmented area, causing pruritis
atrophie blanche
lipodermatosclerosis: subcutaneous tissue replaced by thick fibrous tissue, giving an inverted champagne bottle appearance
ulceration

11

hand held doppler

identify reflux at saphenofemoral/saphenopopliteal junctions

12

duplex scanning

diagnose valvular and perforating vein incompetence as well as large vein occlusion
blue - forward
red - back
