The aim of this study was to evaluate hemodynamic and anatomic alterations of the splanchnic venous system and the efficiency and safety of color Doppler radial endosonography in the assessment of cirrhotic patients by comparing Child A cirrhotic patients without portal hypertension findings versus a non-cirrhotic group.
The study was carried out between January 2009 and February 2010; the study population was 38 cirrhotic patients without portal hypertension and 140 control patients.
Hepatopedal flow was monophasic in all the control patients; the flow pattern was chaotic and irregular in 8% of the cirrhotic patients; in the cirrhotic patients the portal vein diameter was increased and the flow velocity reduced; no differences in flow volume were observed between the two groups. Splenic vein diameter and flow velocity were normal. In the majority of the Child A cirrhotic patients without portal hypertension, no changes were seen in portal vein diameter or flow volume; in some patients no significant increase portal vein diameter was observed and showed the flow volumes were unchanged.
Radial Doppler endosonography may be efficient and safe for assessing the splanchnic system.
本研究旨在通过比较无门静脉高压表现的Child A级肝硬化患者与非肝硬化组，评估内脏静脉系统的血流动力学和解剖学改变以及彩色多普勒径向腔内超声检查在评估肝硬化患者中的有效性和安全性。
研究于2009年1月至2010年2月进行；研究对象为38例无门静脉高压的肝硬化患者和140例对照患者。
所有对照患者肝血流为单相；8%的肝硬化患者血流模式紊乱且不规则；肝硬化患者门静脉直径增大，血流速度降低；两组间血流量无差异。脾静脉直径和血流速度正常。在大多数无门静脉高压的Child A级肝硬化患者中，门静脉直径或血流量未见变化；部分患者门静脉直径未见明显增加且血流量未改变。
径向多普勒腔内超声检查评估内脏系统可能有效且安全。
