Insights

A rare complication during coronary intervention, septal branch perforation, was successfully treated using autologous fat injection. This innovative technique, combined with balloon inflation, effectively sealed the perforation, offering a new approach for managing such events.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Surgery

Background:

  • Percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) carries risks.
  • Septal artery injury is a rare but serious complication during PCI of the right coronary artery.

Purpose of the Study:

  • To report a novel treatment strategy for septal branch perforation during PCI.
  • To demonstrate the efficacy of autologous fat grafting in managing coronary artery perforation.

Main Methods:

  • A case of right coronary artery CTO PCI complicated by septal branch perforation.
  • Treatment involved direct injection of autologous fat into the perforated septal branch.
  • Prolonged balloon inflation at the origin of the septal branch was employed to seal the perforation.

Main Results:

  • Autologous fat administration led to a significant reduction in extravasation.
  • Prolonged balloon inflation definitively sealed the septal branch perforation.
  • The patient tolerated the procedure without further complications.

Conclusions:

  • Autologous fat grafting is a viable and effective treatment for septal branch perforation during PCI.
  • This technique offers a minimally invasive option for managing coronary artery perforations.
  • Further research is warranted to evaluate the long-term outcomes of this approach.
