title: Large pseudoaneurysm after left main trunk stenting sealed by polytetrafluorethylene-covered stent.
abstract: Left main trunk (LMT) aneurysm is very rare and the management remains uncertain. We describe a patient who developed a pseudoaneurysm from coronary perforation during stent implantation in LMT and was then treated with polytetrafluorethylene (PTFE)-covered stent graft. PTFE-covered stent is considered to be a valid strategy for LMT aneurysms.
