Flashcards in Venous Disease Deck (12):
what is venous disease in the deep veins?
deep vein insufficiency
what is venous disease in the superficial veins?
what does venous disease result in?
what are varicose veins?
abnormally dilated and lengthened superficial veins
primary (idiopathic) or secondary
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
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
symptoms of varicose veins
oedema of ankles, particularly on standing for long periods
itching and nocturnal cramps
signs of deep venous insufficiency: haemosiderosis, eczema, lipodermatosclerosis
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
types of deep venous insufficiency
primary - congenital absence of valves
secondary - DVT causing valvular damage or AVF raising venous pressure
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
lipodermatosclerosis: subcutaneous tissue replaced by thick fibrous tissue, giving an inverted champagne bottle appearance
hand held doppler
identify reflux at saphenofemoral/saphenopopliteal junctions
