Bidirectional Glenn. Is XXXX good or bad?

@entity1 @entity204 @entity450
BACKGROUND: The bidirectional Glenn (BDG) is frequently used in the staged surgical management of single ventricle @entity1 . Controversy exists whether @entity450 ( @entity450 ) sources should be left at the time of the BDG to augment systemic saturation or should be eliminated to reduce volume load of the ventricle. The present study was a retrospective review to assess the influence of @entity450 on outcome after the BDG. METHODS AND RESULTS: Ninety-two @entity1 have undergone BDG at our institute during the interval from 1986 through 1994. At the time of BDG, 40 @entity1 had either a systemic-to-pulmonary artery shunt or patent right ventricular outflow tract as an additional source of pulmonary blood flow. Fifty-two @entity1 had elimination of @entity450 . There were three operative @entity204 (two with and one without @entity450 ) and four procedures (two in each group) that failed and required subsequent revision. Thus, there were 85 @entity1 who underwent successful operation. Effusions (defined as chest tube drainage exceeding 7 days' duration) occurred in 8 of 85 @entity1 ; this complication was seen in 7 of 36 @entity1 (19%) with @entity450 and 1 of 49 @entity1 (2%) without @entity450 (P < .05). There were 11 @entity204 , including 6 @entity1 (17%) with @entity450 , 2 @entity1 (4%) without @entity450 , and 3 of the @entity1 (75%) who had a failed BDG. CONCLUSIONS: The data suggest that morbidity and mortality are lower in @entity1 in whom @entity450 is eliminated at the time of the BDG.
