A prospective study was designed to determine the utility of computed tomography (CT) during arterial portography (CTAP) in the detection of superior mesenteric vessels and portal vein involvement in patients with pancreatic adenocarcinoma. Eighteen patients with adenocarcinoma of the head of the pancreas and eight patients with benign pancreatic disease were investigated with CTAP, dynamic contrast-enhanced CT, and angiography. Appropriate review was made to determine presence or absence of superior mesenteric vessels and portal vein involvement. Final diagnosis was obtained in all cases by surgical explorations. The overall accuracy rate for detecting or excluding superior mesenteric vessels and portal vein involvement was 96% (25 of 26 patients) with CTAP, 88% (23 of 26 patients) with dynamic contrast-enhanced CT, and 85% (22 of 26 patients) with angiography. No statistically significant difference in accuracy was found among the three techniques. Our results suggest that the use of CTAP is not indicated in the preoperative detection of superior mesenteric vessels and portal vein involvement in patients with pancreatic adenocarcinoma.
一项前瞻性研究旨在确定动脉门静脉造影（CTAP）期间计算机断层扫描（CT）在检测胰腺癌患者肠系膜上血管和门静脉受累情况方面的效用。对18例胰头腺癌患者和8例良性胰腺疾病患者进行了CTAP、动态对比增强CT和血管造影检查。进行了适当的评估以确定肠系膜上血管和门静脉是否受累。所有病例均通过手术探查获得最终诊断。CTAP检测或排除肠系膜上血管和门静脉受累的总体准确率为96%（26例患者中的25例），动态对比增强CT为88%（26例患者中的23例），血管造影为85%（26例患者中的22例）。三种技术在准确率上没有发现统计学上的显著差异。我们的结果表明，在胰腺癌患者术前检测肠系膜上血管和门静脉受累情况时，不建议使用CTAP。
