Intermittent claudication
Claudication intermittens / arterial intermittent claudication / arteriosclerosis of the blood vessels in the legs / peripheral arterial disease

Intermittent claudication is a condition that affects the blood vessels. It is also known as "arterial intermittent claudication". The patient complains of pain in the legs that occurs whilst walking. The symptoms disappear when the patient stops walking, but start again after walking a similar distance to when the symptoms first started.

Arterial intermittent claudication mainly affects people over the age of 60 years. Only 1 in 2,500 people aged between 25 and 44 years will develop this condition. The name 'shopping legs' arose because people with these symptoms will often pause to look at a shop window when walking in a shopping street. In relaty, they are stopping until the pain subsides. Pausing intermittently allows the pain to dissipate.

Description of the condition

Arterial intermittent claudication is caused by a narrowing of the blood vessels in the leg due to atherosclerosis. Calcium deposits and fatty substances adhere to the inner wall of the arteries. We call this plaque formation. This reduces the blood flow to the leg. This condition is often (incorrectly) referred to as hardening of the arteries.

The plaques that remain in the arteries of the legs will accumulate there and can cause severe narrowing of the artery. This reduces the blood flow to the legs. In turn, the leg muscles do not receive enough oxygen when the patient walks, resulting in the symptoms of the condition.

Cause and origin

Plaque formation is more common in people who smoke. There are various risk factors that can contribute to the development of the condition. For example, diabetes, high blood pressure and a relatively high age. In addition, men have a higher risk of arterial intermittent claudication.

Signs & symptoms

  • Pain, cramping, or a tired feeling in the legs whilst walking or cycling.
  • Standing still or resting reduces the symptoms.
  • The symptoms occur after walking a set distance.
  • The pain is usually present in the calf.
  • The symptoms can also occur in the buttock region, the thigh, the sole of the foot and the toes.
  • The foot of the affected leg can feel colder or become pale.
  • The symptoms occur sooner when walking uphill.
  • In severe cases the symptoms can also be present in rest.

Diagnosis

Treatment

It is important for the patient to stop smoking. High blood pressure and diabetes need to be treated. The patient will be advised to exercise a lot and eat a healthy diet (reducing the consumption of saturated fatty acids).

The physiotherapeutic treatment consists of walking training for at least three months. In almost all cases this will result in an increase in the pain-free walking distance. The patient should walk for 15 - 30 minutes three times a day. The patient should continue walking a few additional metres after the pain occurs before stopping. Once the symptoms have dissipated, the patient should continue walking.

The narrowing of a blood vessel can be alleviated temporarily by means of surgery. However, this only makes sense if the patient changes his lifestyle.
