“…In diesem Zusammenhang stellt die Doppleruntersuchung eine hilfreiche Methode dar die Bypassfunktion zu untersuchen. Eine weitere, angiographische Untersuchung konnte bei 37 Patienten einen subtotalen Bypassverschluß diagnostizieren, welcher dann in diesem Fall angiographisch bestätigt werden konnte (8). Auch andere Gruppen fanden bei höhergradigen Stenosen in Bypassgefäßen eine Änderung der Ratio aus systolischer und diastolischer Spitzengeschwindigkeit zu Gunsten des systolischen Anteils als Marker für eine Bypassdysfunktion (18).…”

During the last 25 years the internal thoracic artery has become a well established conduit for coronary revascularization. Next to angiography, duplex-sonography is increasingly used as a non-invasive imaging procedure for the evaluation of this graft vessel. Preoperative investigation in 117 patients has yielded a high level of agreement between angiography and duplex-sonography. While the preoperative flow-pattern is dominated by systolic flow as it is typical for vessels supplying skeletal muscle, the postoperative findings show an adaptation to the coronary vascular bed as the diastolic flow increases. These non-invasive measurements are well matched with invasive intravascular recordings. Coronary angiography and duplex-sonography of the internal thoracic artery yielded comparable findings in respect to the procedural result. Considering the increasing use of the internal thoracic artery in coronary artery bypass surgery, this non-invasive method should gain increasing relevance.

“…This method is considered to be a useful non-invasive diagnostic tool for investigation of the internal thoracic artery-graft function following operation [49][50][51][52]. With the use of exercise [49] you get an additional information about the assessment of the graft function [53].…”

“…they found higher diastolic than sys tolic flow velocities. Our own study of the flow pattern in the proximal part of the graft from the supraclavicular fossa in 36 patients and the study of de Bono et al are in contrast to this [2,4]. We have studied our patients from two sites: supraclavicular fossa and high intercostal spaces.…”

“…Its applicability is limited by the rate of vessel detection and the influence of the Doppler incident angle on the measurement of absolute graft flow [1], Another aspect of the internal mammary artery graft is the shift of the highest flow velocity from the systole in the subclavian artery to the diastole in the cor onary artery [1][2][3][4]. This change in the flow velocity pattern probably occurs in the mam mary artery graft.…”

In a group of 22 patients, Doppler signals from the proximal part of the internal mammary artery graft were studied from the supraclavicular fossa as well as from the high intercostal spaces. An adequate signal was found more often from the supraclavicular position. Both positions showed higher peak systolic than peak diastolic velocities. Transition of the flow to the typical coronary flow pattern with higher peak diastolic velocity seems to occur in lower parts of the graft.
