Key result
Transcatheter delivery of subcutaneous tissue stops leakage from guidewire-induced distal coronary perforations in three cases.
Why the study?
Coronary leakage after guidewire-induced small coronary artery perforation during PCI can persist despite prolonged balloon inflation and heparin reversal, requiring effective treatment methods.
Does transcatheter delivery of subcutaneous tissue stop leakage in patients with guidewire-induced coronary artery perforation during PCI?

Does transcatheter delivery of subcutaneous tissue stop leakage in patients with guidewire-induced coronary artery perforation during PCI?
Transcatheter delivery of subcutaneous tissue via microcatheter appears to be an effective method for treating guidewire-induced perforations of distal coronary arteries during PCI.
May support bailout use in distal perforations during PCI; hypothesis-generating and requires prospective validation before wider adoption.
In three cases of small coronary artery perforation by guidewires during percutaneous coronary intervention, coronary leakage continued despite prolonged balloon inflation and reversal of heparin. Subcutaneous tissue was selectively delivered to perforated vessels by means of microcatheters in a successful attempt to stop leakage. This method appears to be extremely effective for treating guidewire-induced perforations of distal coronary arteries.

Oda et al. (2005) conducted a case report in Guidewire-induced coronary artery perforation (n=3). Transcatheter delivery of subcutaneous tissue was evaluated on Cessation of coronary leakage. Transcatheter delivery of subcutaneous tissue via microcatheters successfully stopped leakage in three cases of guidewire-induced distal coronary artery perforation.
