    We investigated influence of Doppler angle on peak systolic velocity (PSV). In our hospital, 109 carotid arteries were examined using carotid duplex. The PSVs obtained with a 45˚ and a 60˚ insonation angles at the distal common carotid artery and proximal internal carotid artery were statistically analyzed. The PSV measurements obtained with the two fixed insonation angles were statistically significantly different (p < 0.0001). Doppler insonation angle has a significant influence on PSV. Carotid duplex examination should be performed with a fixed angle in order to obtain reproducible results.

    Background: The aim of this study was to investigate the influence of dialysis on midterm results after treatment of aortic diseases. Methods: Between May 2007 and April 2013, 20 consecutive patients underwent endovascular aortic repair (n=14) and graft replacement (n=6). Of them, 7 patients required emergency procedures due to rupture (n=5) or acute type A aortic dissection (n=2). Results: There were four early deaths. Survival rates at 1 and 3 years were 64% ± 11% and 43% ± 12%, respectively. One patient died of adverse aorta-related events. Freedom from late aortic events at 1, 2, and 3 years were 46% ± 13%, 30% ±14%, and 20% ± 12%, respectively. Late aortic events (n=9) included six new diseases and two endoleaks. Conclusions: Late aortic events occurred in nearly half of dialysis patients undergoing aortic repair. Thus close follow-up surveillance is needed.
