Recanalisation of the left superior caval vein after Fontan procedure: not so rare complication: possibilities of percutaneous closure using various devices.
OBJECTIVE
Evaluation of possibilities of percutaneous closure of recanalised left superior caval vein after total cavopulmonary connection.


RESULTS
We analysed 19 patients after total cavopulmonary connection catheterised because of a sudden increase of desaturation. In four of them, the recanalisation of the left superior caval vein was identified. For this reason, the balloon occlusion tests of the veins were made temporarily. In all cases, the haemodynamic status of patients did not change, and arterial oxygen saturation increased significantly. Thus, using different types of implants, these veins were closed effectively in all patients. During the short-term follow-up, the effectiveness of treatments and constantly maintaining a high level of saturation were confirmed.


CONCLUSIONS
Meticulous investigation of unclear causes of desaturation in cyanotic patients after Fontan completion is necessary. Almost all causes of desaturation, including recanalised additional left superior caval vein, can be effectively treated percutaneously.
