Key result
Autologous preclotted blood injection seals distal LAD perforation while preserving vessel patency.
Why the study?
Coronary vessel perforation during balloon angioplasty requires effective management strategies to seal the perforation and maintain vessel patency.
Injecting preclotted autologous blood through a balloon catheter lumen may be an effective technique to seal distal coronary perforations while preserving vessel patency.

May offer a bailout for distal perforations; hypothesis-generating and requires prospective validation before any practice change.
Coronary perforation can be managed with prolonged balloon inflations, covered stents, or embolization of the vessel. We report on a case of a balloon-induced perforation of the distal left anterior descending artery, that was sealed by injecting preclotted autologous blood through the balloon catheter lumen at the site of the perforation. The patency of the distal vessel was maintained.
