Coronary steal is an often encountered clinical condition attributable to multiple etiologies. Diverse treatment modalities have been previously elucidated.AimTo elucidate the potential role of interventional approach using N-butyl Cyanoacrylate (Histoacryl®) to treat coronary steal.Material and methodsWe present four patients with coronary steal due to different causes. Three patients had coronary arterial fistulas, and the fourth patient underwent prior Coronary Artery Bypass Graft (CABG) surgery with a patent unligated Left Internal Mammary Artery (LIMA) side-branch. We report the attempted trans-catheter closure of the fistulas and LIMA side-branch using n-butyl cyanoacrylate as an embolic agent.ResultsIn our series, Coronary angiography was the imaging modality used for diagnosing and guiding the treatment of all cases. Multi-detector CT was used to track the pathway and termination of the fistula in one case only. From the three fistula cases, two originated from the left anterior descending (LAD) coronary artery and one from the left circumflex (LCX) coronary artery. We accomplished successful occlusion in two of the three fistula cases and in the LIMA side-branch case as well.ConclusionN-butyl Cyanoacrylate (Histoacryl®) is a useful interventional embolic agent that could be used to treat coronary steal of diverse etiology.
