Lower Limb Venous Mapping (CVI Doppler Ultrasound)
Ultrasound is extremely useful in the assessment of Chronic Venous Insufficiency (CVI).
In Patients with Varicose Veins, Varicose Eczema, or Venous Ulceration, it can be used to assess:
* patency of deep veins
* valvular incompetence in the deep venous system
* patency and incompetence in the long and short saphenous superficial veins
* incompetent perforating veins between the deep and superficial systems
* origin and cause of specific varicose veins
Unlike contrast venography, which it has largely replaced for this clincal indication, it is non-invasive and gives information regarding the direction of blood flow. It is also much more accurate in determining the exact position of incompetent perforating veins which can then be marked pre-operatively if required (or their position can be described accurately in relation to known anatomic landmarks).
It is particularly useful in patients with recurrent varicose veins following previous surgery.
Lower Limb Venous Mapping (CVI Doppler Ultrasound) is available on referral from a vascular or general surgeon. It takes approximately 45 minutes per leg and is performed using a combination of lying and sitting positions. Very occasionally patients may feel faint when being examined in the erect position but otherwise this procedure is very well tolerated and requires no specific preparation.
