Patients with locally advanced pancreatic cancer who undergo distal pancreatectomy with resection of the celiac axis (CA) are at risk for postoperative hepatic or gastric ischemia if collateral blood flow from the superior mesenteric artery (SMA) via the gastroduodenal artery is insufficient. This study presents a technique for preoperative angiographic evaluation of these collateral vessels by using an AMPLATZER Vascular Plug to temporarily occlude the CA or common hepatic artery while simultaneously performing digital subtraction angiography of the SMA. If collateral vessels are deemed sufficient, the plug can subsequently be released for permanent occlusion with the intent to enhance the blood flow in these collateral vessels.
接受伴有腹腔干（CA）切除的远端胰腺切除术的局部晚期胰腺癌患者，如果来自肠系膜上动脉（SMA）经胃十二指肠动脉的侧支血流不足，术后有发生肝或胃缺血的风险。本研究提出了一种术前血管造影评估这些侧支血管的技术，即使用AMPLATZER血管封堵器临时封堵CA或肝总动脉，同时对SMA进行数字减影血管造影。如果认为侧支血管充足，随后可释放封堵器进行永久性封堵，以增加这些侧支血管的血流。
