摘要： A novel cardiovascular stent for preventing vascular stenosis is disclosed. The basic components of the cardiovascular stent of the present invention include V-shape rib unit, multi-link unit and connective ring unit. In addition, each ring rib part is formed by a plurality of double V-shape rib units that are connected together via the bridging portions of the multi-link units. Also, each connective part comprises a plurality of connective ring units. The integrally formed stent of the present invention is formed with the ring rib parts that are connected together by the connective parts.

摘要： A method for evaluation of renal perfusion with power Doppler ultrasonography is disclosed in the present invention. Serial renal vascular images at different vascular areas including the whole vascular tree, interlobar, arcuate, and interlobular vessels were captured. Imaging processing software was designed to analyze the changes of power Doppler intensity of colored pixels within regions of interest (ROI). Power Doppler Vascularity index (PDVI) has been defined as the percentage of vascular perfusion within a region of interest (ROI). The renal vascular perfusion index (RVPI) is defined as the maximal power Doppler vascular index divided by minimal power Doppler vascular index (PDVImax/PDVImin) among the serial images. The mean of weighted power Doppler vascular index (WPDVImean) is defined as the average of the intensity of color pixels among the ROI within the serial images. By using the RVPI and WPDVImean, a more dynamic sense of vascular perfusion and a novel approach for the evaluation of renal vascular function in clinical practice can be provided.
