Abstract

We are currently using color-Doppler sonography for preoperative assessment of the IEA anatomical features in patients undergoing myocardial revascularization. Bilateral evaluation was performed in 26 patients. A computed tomographic imager and a 7.5 MHz linear small-parts transducer were used; flow signals were taken by means of a pulsed Doppler technique. Twenty-three patients received a free aortocoronary IEA graft. In 3 cases the IEA was not used as a bypass graft: this was due to sonographic data in 2 patients and to intraoperative exploration in 1. All IEA bifurcations were correctly detected at sonography (6 cases): in 3 patients a bifurcated IEA graft was performed. At sonography, the IEA length ranged from 4.5 to 8.5 cm (6.5 ± 0.34 cm), while at operation suitable IEA length ranged from 9.8 to 15.7 cm (12.9 ± 1.6 cm). Internal diameter was 1.7 to 2.8 mm (2.29 ± 0.1 mm) at echography and 1.8 to 3.0 mm (2.32 ± 0.33 mm) at operation. There was a statistical difference between sonographic and intraoperative findings concerning the IEA length (p <0.01), while the internal diameter measurements did not significantly differ (NS). This was confirmed by linear regression analysis (correlation coefficient = 0.83). In conclusion, color-Doppler sonography appears a reliable, safe and low-cost technique for preoperative evaluation of the IEA as a graft for coronary bypass surgery.
