Station Learning Objectives
• Demonstrate with a clear commentary examination of an ulcer
• Recognise signs & symptoms of chronic venous insufficiency
• recognise other common venous disorders eg. varicosities

Venous Disease
• More common in lower limbs than upper limbs &
• May present as• DVT
• Varicose Veins
• Superficial Thrombophlebitis
• Chronic Venous Insufficiency & ulceration

Venous Disease
• Patients may complain of the following:
– pain– swelling: unilateral / bilateral
– discolouration: lipodermatosclerosis
– ulceration

Chronic Venous Insufficiency
Before you are able to appreciate chronic venous insufficiency (CVI) you must understand how the valves function and the calf muscle acts as a pump aiding return of deoxygenated blood to the heart.

Chronic Venous Insufficiency
CVI = main late complication of deep venous
thrombosis
·incomplete recanalization of vein post DVT +
·incompotent valves results in
·abnormally high hydrostatic pressures while walking or standing
·transmitted to skin via incompetent perforator veins
· capillary filtration & reabsorption of fluids & proteins from interstitial spaces

Examination of Ulcers
1. HISTORY
How long has it been present ?
Is it painful ?
Does it bleed ?
Has the ulcer changed in any way ?
Does the ulcer interfere with daily activities ?
Does the patient have any other ulcers ?
Is there a history of trauma preceding the ulcer ?
Does the patient have any associated diseases ? (varicosities, hypertension, burns, collagen disease, diabetes, vascular diseases, syphilis, TB, osteomyelitis etc.
Has the patient been treated previously for the ulcer ?

Examination of UlcersSituation- gravitational ulcers usually occur on the lower leg above the medial malleolus
Colour- rodent (basal cell carcinoma) ulcer have pearly white edges
- malignant melanomatous ulcers are pigmented
![Page 13: VENOUS DISEASE & CHRONIC VENOUS INSUFFICIENCY](https://reader036.fdocuments.us/reader036/viewer/2022081416/56814cf7550346895dba00e1/html5/thumbnails/13.jpg)
Examination of UlcersEdge- sloping in healing ulcers
- punched-out in syphilitic & trophic ulcers
- undermined in TB or pressure sores
- rolled in basal cell carcinoma
- everted in squamous cell carcinoma
- bluish skin on edge indicates healing
Floor- syphilitic ulcers: wash-leather tissue
- TB unhealthy bluish granulation tissue
- ischaemic ulcers often have no granulation tissue
- redness indicative of good blood supply for healing
- look carefully for exposed bone, tendon & muscle

Examination of UlcersBase (area under floor)- feel for fixity to surrounding structures
- feel for fibrosis which may impair local blood supply
Discharge- serosanguinous
- serous
- bloody
- purulent
Surrounding Skin- eczema with gravitational ulcers
- satellite nodules assoc. with malignant melanoma

Other Venous Disorders
Can you recognise this abnormality ?
Examination of the venous system will be
covered in GEMP III & IV
