为进一步确定脾灌注缺损(SPD)在CT动脉性门脉造影(CTAP)中出现频率、CT表现及其临床价值,作者回顾研究了46例肝肿瘤患者的术前(CTAP)。男性19例,女性27例,年龄39～75岁。先作腹腔动脉和肠系膜上动脉(SMA)的普通血管造影和/或DSA,并将导管固定于SMA作CTAP用。若肝右动脉起源于SMA,则将导管前端超过肝右动脉开口或插入脾动脉。所有CTAP检查均在第三代CT扫描机上进行,自膈顶通过肝脏每层10mm进床行动态扫描。用高压注射器2.5ml/s经导管注入
To further determine the frequency, CT appearance, and clinical value of splenic perfusion defects (SPD) in CT arterial portography (CTAP), the authors reviewed the preoperative (CTAP) of 46 patients with liver tumors. There were 19 males and 27 females, aged 39-75 years old. General angiography and/or DSA of the celiac artery and superior mesenteric artery (SMA) were performed first, and the catheter was fixed on SMA for CTAP. If the right hepatic artery originates from SMA, the tip of the catheter is passed over the right hepatic artery or inserted into the splenic artery. All CTAP examinations were performed on a third-generation CT scanner. Dynamic scanning was performed at 10 mm from each layer of the liver through the dome. Injection with a high-pressure syringe 2.5 ml/s through the catheter
