Three technical modalities are presented with total extracardiac cava-pulmonary connection, with bidirectional Glenn, as coverage of this type of extracardiac connection for all types of cardiopathies suitable for Fontan type correction.
Development of an experimental protocol for the perfecting of the three technical variants tested: "Tunnel from inferior cava to right pulmonary artery by means of right atrial wall and vascularized pericardium", "Tunnel from inferior cava to the trunk of the pulmonary artery with or without pulmonary valve with P.T.F.E. hemiconduit" and "Tunnel from inferior cava to the pulmonary graft as a artery with P.T.F.E. graft as a hemiconduit".
The first two clinical cases operated on using the third technical variant are presented. Both cases evolved during immediate postoperative period with a very favourable hemodynamic response, with pressures at conduit and P.A. level of 10-12 mmHg, normal cardiac output and sinus rhythm. The later clinical evolution in both cases is very satisfactory. The five cases published by Laschinger with this same technique showed a very favourable evolution during the immediate postoperative period and later.
The technical facility of its performance, the slight traumatism of this surgery, the important technical advantages with respect to the total cava-pulmonary intraauricular connection and the good initial hemodynamic results make us consider the total extracardiac cava-pulmonary connection as an important contribution in this type of surgery. It is clear that time and greater clinical experience with this type of connection is required for the correct evaluation of all and each one of the numerous theoretical advantages shown and in order to detect possible disadvantages.
