What is Chronic Venous Stasis?
This is the most advance presentation of venous disease. Patients complain of leg swelling, have pigmentation and induration of the tissues under the skin and develop ulcerations.
Patients present with leg swelling, pigmentation, induration of the tissues under the skin and ulceration. This pathology may be the result of previous episodes of phlebitis in the deep veins (DVT) or it may be due to failure of valves of the superficial, deep or perforating venous system to close properly.
In these advances cases of chronic venous insufficiency it is very important to determine what veins are defective, so that the treatment can be directed to their specific repair. This study is done with duplex ultrasound, phletismography and in some case venography.
When ulcers are present, treatment will consist of:
Weekly Application of Unna Boot
This treatment consists of applying in the affected leg a bandage impregnated in Zing Oxide. This bandage is changes at weekly intervals, until the ulcer is healed.
Occasionally, Skin Grafting may be necessary.
If the ulcer is too large or healing is very slow, a thin slice of skin taken from the same patient’s body is placed over the ulcer. This skin graft is simple and very successful.
