BACKGROUND: Low superior vena cava ( @entity6480 ) blood flow has recently been identified as a marker for bidirectional @entity2597 ( @entity2597 ) failure and @entity204 . Prior innominate @entity2994 is considered a significant anatomic risk factor for @entity2597 failure. We therefore evaluated the outcomes of @entity1 who underwent @entity2597 with known @entity432 . METHODS: Between February 1995 and June 2014, @entity2597 was carried out in 8 @entity1 who had either a single @entity6480 with known prior occlusion of the innominate vein (n  =  6) or bilateral SVCs without a bridging vein with occlusion of one @entity6480 (n  = 2). The cause of the occlusion was an indwelling catheter in 5 @entity1 . These @entity1 were compared with 8 @entity1 with normal upper-body venous drainage who underwent @entity2597 . @entity1 were evaluated for preoperative risk factors (including @entity6480 size, pulmonary artery size, Nakata index, pulmonary vascular resistance), operative factors, and clinical outcomes to determine the impact of prior upper-body @entity432 on @entity2597 failure or @entity204 . RESULTS: There were no significant differences in preoperative risk factors between the two groups, except for a significantly lower Nakata index in the study group with a trend toward smaller pulmonary artery branch size. There were no @entity2597 takedowns or mortalities. There was no significant difference in postoperative length of stay (median of 7 days [range, 5 to 32 days] versus 5 days [range, 4  to 32 days]; p  = 0.17. Study @entity1 had a lower mean systemic @entity26 saturation at discharge, 81% versus 85%  (p  = 0.05). In the study group, at a median follow-up of 42  months, 3 @entity1 underwent successful Fontan completion and 5 are still awaiting Fontan completion. CONCLUSIONS: Although @entity1 with prior @entity432 may have lower systemic @entity26 saturations at hospital discharge, they do not demonstrate an increased @entity2597 failure or mortality rate. Innominate @entity2994 or its equivalent in @entity1 with bilateral SVCs should not preclude the performance of @entity2597 . Physiologic rather than anatomic evaluation of preoperative systemic venous return may be more useful to predict outcome after @entity2597 .

Prior Innominate XXXX Does Not Preclude Successful Bidirectional Superior Cavopulmonary Connection.
