Large vessel perforation during coronary intervention is a rare but serious complication that often requires a covered stent for treatment.
Covered stents have lower long-term success rates compared to drug-eluting stents and should be used with caution due to the risk of misplacing them, which can lead to additional complications.
This text presents a case series aimed at examining the anatomy and mechanisms of large vessel perforations, along with guidelines for successful covered stent implantation.
Article Abstract
Large vessel perforation during coronary intervention is a rare but potentially fatal complication, often requiring implantation of a covered stent for resolution. While technology is improving, the long-term patency of covered stents is less than drug-eluting stents, and implantation of covered stents should be used sparingly. Large vessel perforations are complex and often the perforation inflow is not located at the site of extravasation seen on angiography. This can lead to geographic miss when implanting covered stents and necessitate the implantation of additional covered stents which increases the risk for short- and long-term complications. We present a case series to further investigate the anatomy and mechanism of large vessel perforations and guidance on effective covered stent implantation.
