To evaluate the vascular supply of regions of the pancreas on computed tomography (CT) during arteriography with selective catheterization.
Thirteen patients were included. In each patient we performed conventional arteriography followed by CT during arteriography of each of the arteries: the superior mesenteric artery (SMA), gastroduodenal artery (GDA), and splenic artery (SPA). The regions of the pancreas that were most enhanced on CT during arteriography were considered to be the areas receiving the greatest infusion of blood from the selected artery.
In all 13 patients, the uncinate process, the superior head, and the tail of the pancreas were predominantly supplied by the SMA, GDA, and SPA, respectively. The inferior head of the pancreas was predominantly supplied by the SMA in five patients, the GDA in nine patients, and both the SMA and GDA in one patient. The body of the pancreas was predominantly supplied by the SMA, GDA, and SPA in seven, two, and ten patients, respectively.
The uncinate process predominantly infused by the SMA, the superior head by the GDA, and the tail by the SPA. The patterns of the vascular supply of the inferior head and the body vary from patient to patient.
在选择性导管动脉造影术期间，通过计算机断层扫描（CT）评估胰腺各区域的血管供应情况。
纳入13例患者。对每位患者，我们先进行常规动脉造影，然后在肠系膜上动脉（SMA）、胃十二指肠动脉（GDA）和脾动脉（SPA）造影期间进行CT扫描。动脉造影期间CT上强化最明显的胰腺区域被认为是从所选动脉接受最大血液灌注的区域。
在所有13例患者中，胰腺钩突、胰头上部和胰尾分别主要由SMA、GDA和SPA供血。胰腺头部下部在5例患者中主要由SMA供血，9例由GDA供血，1例由SMA和GDA共同供血。胰腺体部在7例、2例和10例患者中分别主要由SMA、GDA和SPA供血。
钩突主要由SMA灌注，胰头上部由GDA灌注，胰尾由SPA灌注。胰腺头部下部和体部的血管供应模式因人而异。
