Abstract
In 22 patients with deep venous insufficiency, thermography performed at rest and immediately after exercise was compared with conventional ascending phlebography. Thermography had a high sensitivity in detecting incompetent perforating veins, while the specificity was low. Noninvasive thermography is an attractive technique for preoperative detection of perforating veins.
