Leg ulcers are a common side effect of venous stasis. The condition causes blood to pool in the affected veins.
Venous stasis are common in individuals with diabetes, and are more prevalent in females than males. The condition, which is an effect of the venous wall not working at optimum levels, causes blood to pool in the affected veins, causing stasis.
A 15-year study undertaken by BSN-JOBST examined whether or not assisting the venous wall to pump blood back to the heart would help lower the chronic applicability of venous stasis ulcers.
The study examined 119 patients who suffered from chronic venous stasis ulcers prior to starting the project. All participants were fitted with various types of compression stockings:
89 percent of study participants were fitted with 30-40 mmHg knee-length stockings
7 percent were fitted with 30-40 mmHg thigh-length stockings
2 percent had 20-30 mmHg knee-length compression stockings
Due to amputations and death, six patients were unable to complete the extensive study. Of the 113 that did, 102 maintained the use of their compression stockings. Of these, 99 individuals saw their chronic ulcers heal completely, with an average healing period of 4.8 months within the first year.
Over the 15-year period, information was maintained for 73 of the original 119 study patients. Of these 73, 15 did not maintain their stocking regimen, and of these, all 15 saw their venous stasis ulcers reappear within 36 months.
Although the results of the BSN-JOBST are far from exhaustive, it does provide good indication that constant compression on the lower extremities will help eliminate any issues with venous pressure. However, some individuals may find better results with the use of other treatments, such as Unna Boots, which creates a type of compression cast around the leg, as well as surgery – the latter option can prove immediately effective if the ulcer is showing signs of infection.
