BACKGROUND: Surgery or intervention therapy has been performed to correct kinks of internal thoracic artery (ITA) grafts. The aim of this study was to evaluate the natural course of the ITA graft kink and to clarify whether surgery or intervention therapy should be performed in asymptomatic patients during the early postoperative period.
METHODS: We investigated the early and follow-up angiographic results of ITA graft kinks in 7 consecutive patients who did not undergo surgical or interventional correction. The graft diameter and percentage of diameter stenosis at the kink site were compared between the early postoperative angiography and the follow-up angiography.
RESULTS: Early postoperative angiography revealed that the diameter stenosis at the kink site was 60.1% +/- 6.9% (range, 51 to 69) and the diameter at the kink site was 0.92 +/- 0.20 mm (range, 0.63% to 1.25%). The ITA kinks disappeared in all the patients and the diameter of the ITA graft adjacent to the kink was not significantly changed on the follow-up angiography. No luminal irregularity or indentation was shown. All the patients had been free from cardiac events until the follow-up angiography.
CONCLUSION: Kinking of an ITA graft that's seen on the early postoperative angiography might improve without surgery or intervention. The natural course of ITA graft kinks should be considered when detecting these kinks on the early postoperative angiography when the patient is asymptomatic.
