The authors present ethiology and aethilogy-based surgical techniques of the disorder on a group of 3458 patients operated for varices of lower extremities. Crossectomy is flashed out as a key moment of the procedure in cases of sapheno-phemoral junction insufficiencies. The results are presented on two patient groups comparing relaps rates of the disorder following completion of partial selective and radical complete crossectomies. A subject of neovascularization and its relation to the procedure and relapses is discussed.
