We carried out a retrospective assessment of sclerotherapy case studies on 540 patients at ten phlebological centres to search for a relationship between the use of aminaftone (a venotropic drug with demonstrated anti-endothelin action) and the occurrence of side effects after sclerotherapy was performed. Significant reduction of side effects was observed in sclerotherapy for teleangectasias and in patients with migraine history.
