title: From Fegan forwards.
abstract: We use injection therapy under the following circumstances: 1. After groin ligation in all cases with LSV varices and associated veins in thigh and around the knee. 2. When veins remain after groin ligation +/- stripping. 3. All patients with below knee veins whether new or previously operated affecting LSV or SSV. 4. Dilated dermal telangiectasis. 5. In the management of some ulcers. Why do methods of treatment go wrong? 1. Incomplete documentation and out of date examination of the patient. 2. Failure to follow the correct technique of treatment. 3. Failure to recognize deep venous insufficiency or underestimating stasis complications. Our indications for investigating the deep veins before treatment are: 1. Persistent oedema of the leg. 2. Recent or recurrent phlebothrombosis.
