Lower Limb Iscahaemia
This involves blockage of the arteries of the lower leg which may present in 2 different ways. Firstly the patient may experience pain in their calf muscle on walking. This condition is called intermittent claudication. The pain is typically relieved with rest. the walking distance is less when one walks up a hill or an incline. The problem is a reduction in blood flow to the muscles due to a build up of plaque in the arteries of the leg which could be a narrowing or a blockage of the artery. This condition is seldom related to critical blood flow problems and treatment is only required in a minority of circumstances such as significantly reduced exercise tolerance such that the patients lifestyle is severely threatened. It is unusual for the blockage to progress to the extent that the limb is threatened. Treatment always involves control of risk factors which include cessation of smoking, control of blood pressure and cholesterol, and regular exercise. Definitive treatment may involve either a balloon angioplasty or a bypass.
