胰原性区域性门脉高压症血流动力学的临床研究

目的：研究胰原性区域性门脉高压症静脉血流动力学改变。方法：利用彩色多普勒及直接测量法测量血流动力学及脾静脉压力。结果：门静脉、肠系膜上静脉的血管直径、平均流速在两组间无差异。实验组脾静脉直径扩张，流速降低且静脉压力明显升高（Ｐ＜０．０５）。结论：胰原疾病可导致区域性门脉高压，正确的治疗方法是行脾脏切除术。

CLINICAL HEMODYNAMIC STUDY ON PANCREATOGENOUS LOCAL PORTAL HYPERTENSION

Objective:To study venous hemodynamic changes during local portal hypertension.Methods:Hemodynamic parameters,and splenic vein pressures were measured with color Doppler′s ultrasonic flowmeter and direct pressure measuring instrument in test group and control group respectively.Results:There were no statistical differences in the diameters of portal vein and superior mesenteric vein and in their mean flow rates between the two groups;but splenic vein of the test group had an enlargement in its diameter,a decrease in flow rate,and a marked increase in venous pressure (P<0 05).Conclusion:Pancreatic disease can lead to local hypertension and the correction treatment is splenectomy.
