Stent Placement Compared with Balloon Angioplasty for Obstructed Coronary Bypass Grafts
Why the study?
Does placement of Palmaz-Schatz stents reduce angiographic restenosis compared to standard balloon angioplasty in patients with obstructive disease of saphenous-vein grafts?
Population
220 patients with new lesions in aortocoronary-venous bypass grafts
Comparison
Placement of Palmaz-Schatz stents vs Standard balloon angioplasty
Design
RCT, randomly assigned
Follow-up
six months

Implication
Stenting did not significantly reduce restenosis versus angioplasty in saphenous-vein grafts; leaves open whether procedural gains improve long-term angiographic outcomes.
Structured PICO
Does placement of Palmaz-Schatz stents reduce angiographic restenosis compared to standard balloon angioplasty in patients with obstructive disease of saphenous-vein grafts?
P
Population
220 patients with new lesions in aortocoronary-venous bypass grafts (obstructive disease of saphenous-vein grafts after coronary-artery bypass surgery)
I
Intervention
Placement of Palmaz-Schatz stents
C
Comparator
Standard balloon angioplasty
O
Outcome
Angiographic restenosis at six monthssurrogate
Stenting of saphenous-vein grafts resulted in superior procedural outcomes and reduced major cardiac events compared to balloon angioplasty, although it did not significantly reduce angiographic restenosis.
