Cent Eur J Urol 2013; 66: 215-216 DOI: 10.5173/ceju.2013.02.art26 Dupplex Doppler study after intracavernosal injection (ICI) of vasoactive drugs is a valuable tool in the evaluation of vascular status in patients suffering from erectile dysfunction [1]. Normal erection after ICI suggests sufficient venous occlusion. Persistent diastolic cavernous blood flow measured by end–diastolic velocity (...

Objective: To analyze normal hemodynamics in the extracranial part of internal carotid arteries (ICA) and vertebral (VA) with reference to age gender. Methods: Angle-corrected flow velocities (peak-systolic velocity, PSV end-diastolic EDV) VA diameter were measured, waveform parameters calculated (pulsatility index, PI resistive RI) on 227 healthy adults (125 women). Results: Except for a sligh...

Transrectal color and power Doppler ultrasonography was used to study uterine blood flow and perfusion in mares with and without uterine cysts. Vascular perfusion of the uterus and blood flow velocities, vascular perfusion, diameter, circumference, and area of a cross section of the mesometrial attachment were evaluated. To study the effect of internal cysts, two matched groups (cystic and cont...

Understanding diastolic function mandates feasible and accurate methods to construct and compare the diastolic pressure (P)-volume (V) relationship (PVR). This study compared the relaxation-corrected single beat (RC-SB) to the multiple-beat (MB) (vena cava occlusion) method for constructing the diastolic PVR in 26 young normal or old hypertensive dogs before and after increases in afterload (ph...

BACKGROUND Left ventricular hypertrophy (LVH) is traditionally classified as concentric or eccentric, based on the ratio of LV wall thickness to chamber dimension. We propose a 4-tiered LVH classification based on LV concentricity(0.67) (mass/end-diastolic volume(0.67)) and indexed LV end-diastolic volume (EDV). METHODS AND RESULTS Cardiac MRI was performed in 2803 subjects and LVH (n=895) wa...

Background—Left ventricular hypertrophy (LVH) is traditionally classified as concentric or eccentric, based on the ratio of LV wall thickness to chamber dimension. We propose a 4-tiered LVH classification based on LV concentricity (mass/end-diastolic volume) and indexed LV end-diastolic volume (EDV).

BACKGROUND While mammalian heart size maintains constant proportion to whole body size, scaling of left ventricular (LV) function parameters shows a more complex scaling pattern. We used 2-D speckle tracking strain imaging to determine whether LV myocardial strains and strain rates scale to heart size. METHODS We studied 18 mice, 15 rats, 6 rabbits, 12 dogs and 20 human volunteers by 2-D echo...

We describe the vasculature of the camelid testis using plastic casting. We also use color pulsed-wave Doppler ultrasonography to measure testicular blood flow and compare the differences between testicular blood flow in fertile and infertile camelids. The testicular artery originates from the ventral surface of the aorta, gives rise to an epididymal branch, and becomes very tortuous as it appr...
