Considering the high number of our patients receiving immunosuppressive therapy, the immunization record is alarmingly poor supporting the need for optimized IBD guidelines, better awareness, and patient education. In addition, the screening for chronic infections appears to be useful as suggested by the positive finding of a previously unknown hepatitis C.
Detection of renal artery stenosis (RAS) using Doppler is difficult to evaluate, particularly under conditions such as bilateral RAS or difficultly accessible renal arteries (RA). The objective of the present study was to assess the utility of splenic arterial compared to renal flow as an additional parameter in the Doppler evaluation of RAS. The difference between the resistive indices (RI) determined in renal and splenic parenchymal arteries (ΔRIK−S) was evaluated in 181 hypertensive subjects without any evidence of RAS. Subsequently 47 RA in 24 patients with suspected RAS were angiographically assessed. A ΔRIK−S of 0.055 (median) was determined in the population without any evidence of RAS similar to RA with angiographically excluded stenosis (ΔRIK−S 0.068). In contrast, in angiographic proven RAS, ΔRIK−S was significantly lower (−0.050; P < .005). The assessment of the ΔRIK−S, proved to be an easily feasible parameter, which improves the diagnostic accuracy in the detection of RAS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
