Pletal). These drugs act differently. Trental decreases the “stickiness” (viscosity) of blood and thereby improves its flow to the legs. Pletal acts to dilate (widen) the arteries by decreasing the action of an enzyme, phosphodiesterase III. It also reduces the ability of blood to clot.
If conservative therapy is inadequate, correction of the narrowing in the affected artery may be suggested. This option depends on the location and severity of the narrowing in the artery and the underlying medical condition of the patient. Procedures that are used to correct the narrowing of arteries include surgery (such as bypass grafting) and interventional radiology (such as balloon angioplasty). When claudication is severe and persistent, these procedures may be required to ultimately relieve the condition and the pain.
The word “claudication” comes from the Latin “claudicare” meaning to limp. (The Roman emperor Claudius, who ruled from A.D. 41-54, was so named because he limped, probably because of a birth defect.) There is also venous claudication, resulting from inadequate venous drainage.

the part below the knee. The lower leg contains two long bones. The larger of these two bones is the tibia, the smaller one the fibula. The tibia is familiarly known as the shinbone. “Tibia” is a Latin word meaning both shinbone and flute. It is thought that “tibia” refers to both the bone and […]
- Leg, upper
More properly called the thigh, the upper leg is the area between the knee and the hip. It has only one bone, the femur, which spans the distance from the hip to the knee.
- Legal blindness
Visual acuity of 20/200 or worse in the better eye with corrective lenses (20/200 means that a person at 20 feet from an eye chart can see what a person with normal vision can see at 200 feet); or Visual field restriction to 20 degrees diameter or less (tunnel vision) in the better eye. Note […]
