Report as an information and methods 1.1 General Information The group of 32 patients with liver cirrhosis with portal hypertension patients. 22 male and l0 female patients; age from 32 to 60 years were confirmed by laboratory tests, ultrasound and diagnosis of gastrointestinal Chin meal examination, which confirmed 18 cases of liver cirrhosis of the liver biopsy. 3j patients to our hospital the other health workers served as normal controls. 23 male and female l2 cases; aged 24 to 62 years old Toshiba SonolayerSSA a color Doppler ultrasonic diagnostic apparatus 207A, which have the CDFI (color Doppler flow imaging) and PD (pulse Doppler) systems,<a href="http://www.mbtshoes-outlet.net" target="_blank" class="postlink">mbt shoes outlet</a>, the probe Detection of frequency 3.75/2.5MHz1.2 routine examination of liver and kidney function in both groups. Suspended from l week before the examination of hemodynamics of drugs such as diuretics, fasting vasoactive drugs 1411, when the next morning after 10 minutes supine fasting accurate measurement of blood pressure, pulse and record. Take the portal vein, Volume 39, 1999, Shandong Medical K6 8 small size _ * Temple''I splenic artery (SPA) the right hepatic artery (RHA) five vessels were exploration, after the freezing of the image spectrum to achieve a satisfactory control tracing buffer ball depicting flow spectrum, calculate the maximum venous flow (Vp), mean velocity (Vm) and arterial peak systolic velocity (Vp), end diastolic velocity (Vd) and mean velocity tVn pulsatility index (P1), resistance index (R1) RI and P1, respectively,<a href="http://www.scarpe-adidas.net" target="_blank" class="postlink">adidas scarpe</a>, by the following formula: RI = (Vp-Vd) /, 'p. P1 a (Vp-Vd) / Vm. Venous blood flow velocity by the following formula and blood flow: V a V × 0.57, Q-A · V × 0.57 × 60 (ml / rain). Results x ± S, said t-test comparison between the two groups. 2 results in Table l compared with control group patients with widened portal vein diameter,<a href="http://www.mbtshoesscarpe.com" target="_blank" class="postlink">mbt scarpe</a>, flow velocity decreased, no significant changes in blood flow; the two groups have the same change in superior mesenteric vein; splenic vein diameter and flow increased arterial flow slows down the liver and spleen diameter, flow, resistance index, pulsatility index were significantly increased. Hepatic artery velocity (PV), splenic vein (SPV), superior mesenteric vein (SMV), changes not, and splenic artery flow velocity increased hemodynamic parameters Table 1 Comparison of three groups to discuss the existence of previous detection of portal hypertension, and more by catheter or surgical blood pressure when measured directly. The measured value is far more reliable, but is an invasive, non-physiological conditions, and measurement of portal blood flow may not reflect the true state of dynamic ultrasound technology, and more limited to the liver and spleen size and portal vein, splenic vein After measuring the diameter of our findings, duplex Doppler technique can be used to achieve target blood vessel diameter and blood flow spectrum, which can calculate the velocity of blood vessels, flow and artery P1, R1, conducted a more detailed analysis of the hemodynamics,<a href="http://www.toryburchreva.net" target="_blank" class="postlink">tory burch reva</a>, for better understanding of the hemodynamics of portal hypertension disorder mechanism and provide the basis for observed treatment effect. · 20 · Kwo, etc. to the portal vein velocity of less than 0.1jcn / s as the diagnostic criteria for portal hypertension. According to the group of observations, we believe that in order to 0.13m / s is appropriate, which may be related to ethnic differences and patient selection. Resistance index and pulsatility index of arterial systolic and diastolic flow velocity and hemodynamic parameters obtained by the relevant organs of portal hypertension is still rare reports of resistance index of the study confirmed that patients with hepatic artery resistance index and pulsatility index were significantly higher than normal,<a href="http://www.mbtshoesitalia.net" target="_blank" class="postlink">mbt shoes italia</a>, indicating that patients with cirrhosis of the liver and spleen were the presence of high resistance state, the treatment of portal hypertension should take into account the pathophysiological changes.
