Superior vena cava syndrome

Procedural complications can include stent thrombosis or migration, dissection, perforation, bleeding, infection, or cardiac tamponade.

May require percutaneous or surgical intervention.

There is a risk of volume overload or heart failure exacerbation immediately following revascularization due to sudden increase in venous return.

Minor or major bleeding complications can be related to systemic anticoagulation. They might necessitate holding the anticoagulant regimen, or possibly giving an antidote.
