18 maj 2023 · Renal artery stenosis (RAS) (plural: stenoses) refers to a narrowing of a renal artery. When the process occurs slowly, it leads to secondary hypertension. Acute renal artery stenosis does not lead to hypersecretion of renin.

27 lip 2024 · These then divide into lobar branches which successively branch into interlobar, arcuate, and interlobular arteries. The afferent arterioles, which supply the glomeruli , originate from the interlobular arteries.
12 paź 2009 · Other authors found that renal-interlobar ratio (RIR), i.e. a ratio of PSV measured in the renal artery to that obtained in the interlobar artery, was more accurate (sensitivity 88%; specificity 88%).
30 lip 2021 · Complete renal vascular Doppler assessment involves determining the patency and waveform of the main renal artery and vein; the waveform of the arcuate and interlobar arteries in the upper, interpolar, and lower pole regions; and their associated resistive index (RI).
31 gru 2018 · Ultrasonographic measurements. Knowledge on the nature of blood flow and standard blood flow parameters for healthy vessels is crucial in the diagnosis of renal arterial stenosis. The spectrum of blood flow velocity in renal arteries and their branches is a low resistance one.
12 cze 2017 · The segmental arteries branch further within the renal sinus and give rise to the interlobar arteries (Fig. 10.1b). Every interlobar artery divides into two interlobular arteries which penetrate the renal parenchyma (Fig. 10.1b). They run adjacent to the medullary pyramids.
5 cze 2023 · The segmental arteries supply end arteries to the renal parenchyma and divide further into lobar, interlobar, arcuate, and interlobular arteries. The interlobular arteries supply the afferent glomerular arterioles, which, in turn, feed into the glomeruli.
