摘要
目的:探讨胰十二指肠上前动脉(ASPDA)、上后动脉(PSPDA)和胰十二指肠下前动脉(AIPDA)、下后动脉(PIPDA)及其侧支吻合在多层螺旋CT血管成像(MSCTA)中的显示情况。方法:搜集无腹腔动脉(CA)、肠系膜上动脉(SMA)、肠系膜下动脉(IMA)狭窄闭塞且行腹部MSCTA检查的病例230例,采用容积再现(VR)和血管生长技术(AV)对胰头、十二指肠区域供血动脉及吻合支进行血管重建,分析其表现。结果:230例检查者中,ASPDA、PSPDA、AIPDA、PIPDA直径分别为(1.50±0.15)mm、(1.60±0.16)mm、(1.50±0.10)mm、(1.70±0.11)mm,显示率分别为90.4%(208/230)、95.7%(220/230)、87.8%(202/230)、90.0%(207/230)。前、后动脉弓直径分别为(2.90±0.15)mm、(3.00±0.17)mm,显示率为53.0%(122/230)。胰背动脉直径(0.80±0.15)mm,显示率为74.8%(172/230)。PSP-DA、PIPDA起源变异发生率为3.0%(7/230),其他侧支吻合发生率为5.2%(12/230)。结论:MSCTA能清楚显示胰头、十二指肠区域供血动脉的起源、变异及吻合支。
Objective：To discuss multi-slice spiral CT angiography（MSCTA） imaging manifestation of anterior superior pancreatoduodenal artery（ASPDA）,posterior superior pancreaticoduodenal artery（PSPDA）,anteror inferior.pancreaticduodenal artery（AIPDA）,posterior inferior pancreaticduodenal artery（PIPDA）,and their collateral circulations.Methods：230 adults patients（without stenosis or occlusion of celiac artery,superior and inferior mesenteric artery） underwent MSCTA to study characters of collateral circulation and feeding arteries of pancreaticoduodenal region vessels were studied.Volume rendering and ＂Add vessel＂ technique were employed.Results：In these 230 cases,vessel diameter of ASPDA,PSPDA,AIPDA,and PIPDA were（1.5±0.15）mm、（1.6±0.16）mm、（1.5±0.10）mm、（1.7±0.11）mm respectively,visualization ratios were 90.4%（208/230）、95.7%（220/230）、87.8%（202/230）、90.0%（207/230） respectively.Diameter of the front and back arterial arcades were（2.9±0.15）mm、（3.0±0.17）mm and visualization ratio were 53.0%（122/230）.Diameter for artery of the back of pancreas were（0.8±0.15）mm and visualization ratio were 74.8%（172/230）.The incidence rate in anomalous origin of PSPDA、PIPDA was 3.0%（7/230）,the incidence rate of other collateral flow was 5.2%（12/230）.Conclusions：The origins,variations of arteries and collateral circulations of pancreaticoduodenal region could be clearly observed with MSCTA.
