PTCA of gastroepiploic bypass using standard devices can induce severe spasm, which may be avoided by modifying the guide catheter position.
When performing PTCA on a gastroepiploic bypass, modifying the guide catheter position may help avoid severe graft spasm.
Alerts to spasm risk with standard devices in gastroepiploic PTCA; leaves open optimal positioning strategies pending further study.
A technique for percutaneous transluminal coronary angioplasty (PTCA) of gastroepiploic bypass is described using standard PTCA devices. Severe spasm of gastroepiploic bypass occurred. Modification of guide catheter position is suggested to avoid inducing gastroepiploic bypass spasm.
