Everything points to the prime importance of good health habits and the prevention of risk factors. Long-term medication has only a limited and still questionable impact. Surgery will never be proposed straight off, but only if the claudication is persistent and troublesome in an active individual. Lumbar sympathectomy always provides a degree of improvement and entails a minimal risk. There is no secondary deterioration. Yet in cases of associated phlebites, it can aggravate trophic skin problems. Reconstructive surgery gives far better immediate results but at the price of increased risk and a secondary deterioration that makes difficult repeat operations necessary. It is thus necessary to be very careful in using surgery to deal with intermittent claudications.
