Annotation for Point H

In the setting of progressive severe vessel narrowing or pseudoaneurysm enlargement, stents have been deployed in an effort to maintain vascular patency.^11,32 A review of the Denver experience found a 17% incidence of stent-related complications and 45% occlusion rate, suggesting that risks exceed benefits.³⁷ On the other hand, the Memphis group¹⁹ reported a good safety and patency record. It is clear that controlled trials are needed, caution should be used during stent deployment to avoid dislodging unstable thrombus, and poststent antithrombotic therapy is critical. It is not advisable to deploy stents within the first several days after injury.
