目的探讨640层螺旋CT门静脉成像在门静脉高压中的应用价值。方法 30例疑似门静脉高压患者作为病例组,30例入院行健康检查者作为对照组,均给予螺旋CT扫描,观察并对比成像结果 ,及术中探查结果与术前检查结果的相符情况。结果病例组门静脉属支及侧支循环血管均出现扩张或迂曲,门静脉主干清晰成像28例,显影不全2例,与对照组相比较,图像存在显著差异。病例组26例符合手术适应证者进行手术治疗,术中经探查其结果与术前经螺旋CT扫描结果完全相符,其中单纯脾切除术3例,贲门周围血管断流术19例,近端脾腔分流联合贲门周围血管离断术4例,术后均恢复良好。结论 640层螺旋CT门静脉成像可清晰、立体地显示门静脉属支、侧支血管循环情况,对门静脉高压症的确诊及相关周围器官病变或血管条件的诊断均可提供显著参考依据,同时为手术治疗方案的制定提供有效指导,应用价值显著。
Objective To explore the value of 640-slice spiral CT portography in portal hypertension. Methods Thirty patients with suspected portal hypertension were enrolled as the case group and 30 hospitalized patients as the control group. All patients were given spiral CT scans, and the results of imaging and imaging were compared with the results of preoperative examination. Results The cases of portal vein branches and collateral vessels were dilated or tortuous, the portal vein clear imaging of 28 cases, 2 cases of incomplete imaging, compared with the control group, there are significant differences in the image. 26 cases of patients with surgical indications for surgical treatment, intraoperative exploration by the results of preoperative spiral CT scan with complete results, including simple splenectomy in 3 cases, 19 cases of cardial peripheral vascular bypass, proximal spleen Gastric shunt combined with pericardial vascular disconnection in 4 cases, were recovered well. Conclusions 640-slice spiral CT portography can clearly and stereoscopically display portal vein branches and collateral circulation, provide a significant reference for the diagnosis of portal hypertension and the diagnosis of peripheral organ diseases or vascular conditions, and provide a good reference for surgical treatment Program formulation provides effective guidance, the application value is remarkable.
