Disorders - Overview
Inflammatory Bowel Disease (IBD) is at least two, separate disorders that cause inflammation (redness and swelling) and ulceration (sores) of the small and large intestines. These two disorders are called ulcerative colitis and Crohn's disease. Although they share some similarities, there are key differences between the two.

1. Venous insufficiency is a condition in which the veins have problems sending deoxygenated blood from the extremities back to the heart. Inadequate blood flow increases hydrostatic pressure within the venous system, leading to the failure of the venous valves which act to stop negative blood flow and the onset of venous stasis, when a large volume of blood accumulates in the lower extremities. If this increased hydrostatic pressure is not treated, it leads to Chronic Venous Disease (Browse NL, 1982). Table 1 provides an indication of the common conditions associated with venous insufficiencies and the prevalence of Chronic Venous Disease (CVD).
How to calculate the ankle-brachial index (ABI). With the patient positioned supine with the ankles and arms at the level of the heart, a health care provider measures the blood pressure in all four limbs using a hand-held Doppler device with a blood pressure cuff and sphygmomanometer. For a standard ankle-brachial index measurement in clinical practice, the higher of the two ankle pressures measured at the ankle is used as the numerator and the higher of the two arm pressures is used as the den
