[Percutaneous femoro-porto-jugular venovenous shunt in orthotopic liver transplantation].

Veno-venous bypass (VVB) by the percutaneous introduction of cannulas in the right internal jugular vein during liver transplantation may reduce the complications derived from the classical method of axillary vein dissection. The results and complications observed over a two and a half year period in 126 consecutive patients submitted to liver transplantation in whom preparation for femoral-portal-jugular veno-venous bypass was carried out are reported. Twelve complications (9.5%) were observed in the 126 patients. All the complications were due to jugular cannulation and were divided as follows: in 7 patients (5.5%) some of the guide introductions were unsuccessful following multiple punctures; in 2 patients (1.6%) the right carotid artery was punctured; 2 hemothorax (1.6%) were observed and one pneumothorax (0.8%). Forty patients required veno-venous bypass. The blood flows obtained during VVB were suffice in all the cases with a mean +/- standard deviation of 2.21 +/- 0.44 l/min-1. The technique of femoral-portal-jugular veno-venous bypass is a good alternative to the classical method of the axillary approach. It has advantages such as in the speed of installation of VVB and the utility of the large jugular vein during the remainder of the surgery for rapid fluid transfusions. Although the number of complications is low, they may be important thereby hindering intra management and post operative of the patients.
