A Study of Cryopreserved Human Femoral Vein Valve for Surgical Correction of the Deep Venous Reflux

In primary deep-vein incompetence, valve repair had produced in numerous series (Kistner, Perrin, Raju, Sottiurai) good clinical and hemodynamic results. In postthrombotic syndrome, the results of transplantation or transposition (valve transfer) are variable, depending upon the study (Eriksson, O’Donnel, Nash, Perrin, Taheri, Raju, Sottiurai). Some authors have described secondary failure after axillary valve transfer. If human preserved valve-containing segments could be stored and used to treat PTS sur-
