There is limited reported experience of catheterization therapy for @entity8404 ( @entity8404 ) at a surgical site in the early postoperative period. We reviewed the clinical course of @entity1 undergoing interventional catheterization for @entity8404 at a surgical site < 7 weeks after surgery. @entity384 ( @entity384 ) was defined as > 50% increase in predilation diameter. From 1984 to 2000, 17 @entity1 had 19 proximal pulmonary arteries dilated 1 to 46 (median 8) days postoperatively. Median age and weight were 3.1 year and 12.7 kg. Three arteries were initially occluded. Seventeen arteries had initial @entity2403 with postintervention imaging available in 15; 8 arteries had @entity384 . The arterial diameter increased from 3.9 +/- 2.6 to 5.5 +/- 2.8 mm (P < 0.001). Nine of these arteries had stents placed with diameter increasing to 8.7 +/- 3.7 mm (P < 0.001 compared with post- @entity2403 diameter). Stents increased the diameter in all arteries and made four of four failed @entity2403 successful. In the two most recent procedures, stents were placed without prior @entity2403 with diameter increasing from 1.3 to 9 mm and 8.2 to 14 mm. A stent was placed in 1 of 7 arteries prior to 1993 and in 10 of 12 arteries thereafter (P < 0.004). Three @entity1 prior to 1995 had catheterization-related deaths secondary to @entity397 after @entity2403 . @entity2403 produces @entity384 in approximately one-half of the procedures but is associated with mortality. Stent placement increases vessel diameter substantially more than @entity2403 alone. Stents reduce the acute complication rate and avoid early reoperation in this @entity1 group.

Interventional catheterization management of perioperative XXXX : balloon angioplasty or endovascular stenting.
