Zusammenfassung

Background: Detection of restenosis by morphologic differentiation of perfused lumen from plaque is an unresolved issue for ultrasonography (US). Therefore in large trials for evaluation of target lumen reduction (TLR) mostly indirect US-parameters like peak velocity ratios are used in addition to angiographic lumen measurement. Aim: To quantitatively assess TLR as a marker of sonographic morphometry by bidirectional power doppler (BPD) as compared to conventional Color-Doppler (CCD), hemodynamic changes in flow-velocity and angiography. Methods: US was performed with a IU 22 (Philips Germany, Hamburg) using a l…
