【摘要】：目的:探究肝左葉一過(guò)性灌注異常與肝動(dòng)脈變異之間的相關(guān)性,以提高對(duì)肝動(dòng)脈變異的認(rèn)識(shí)。方法:篩查2015年06月-2015年12月上腹部雙期增強(qiáng)CT檢查的連續(xù)性病例1275例,所有病例均按照統(tǒng)一掃描方案行動(dòng)脈期、門靜脈期雙期掃描。收集肝左葉表現(xiàn)為葉段性分布的一過(guò)性灌注異常者,并記錄是否存在肝動(dòng)脈變異;按Hiatt分型進(jìn)行分類,分析肝動(dòng)脈變異與肝左葉一過(guò)性灌注異常的相關(guān)性。結(jié)果:1275例連續(xù)性病例中33例符合納入標(biāo)準(zhǔn),肝左葉一過(guò)性灌注異常均呈肝葉或肝段分布,以多個(gè)肝段同時(shí)出現(xiàn)居多(30/33)。MSCT表現(xiàn)為動(dòng)脈期肝左葉或1~3個(gè)段均勻性密度增高,平掃及門靜脈期為等密度;其中肝S3分布2例(對(duì)應(yīng)血管變異為HiattⅣ型、腹腔干與腸系膜上動(dòng)脈共干各1例),肝S4分布1例(對(duì)應(yīng)血管變異為HiattⅡ型1例),肝S2加S3分布15例(對(duì)應(yīng)血管變異為HiattⅡ型9例,HiattⅤ型1例,肝左動(dòng)脈粗大2例,無(wú)血管變異3例),肝S2、S3及S4分布15例(對(duì)應(yīng)血管變異為HiattⅡ型6例,HiattⅢ型4例,HiattⅤ型2例,HiattⅣ型、肝左動(dòng)脈粗大、肝右動(dòng)脈起自于腹腔干各1例)。本組3例肝左動(dòng)脈粗大分別表現(xiàn)為直徑超過(guò)肝右動(dòng)脈17%、28%、40%。肝左葉一過(guò)性灌注異常與肝動(dòng)脈變異存在顯著相關(guān)性(χ2=35.9,P=0.022),以肝左動(dòng)脈變異為主(64%)。結(jié)論:肝左葉表現(xiàn)為葉段性分布的一過(guò)性灌注異常者常存在肝動(dòng)脈變異,該征象對(duì)CT診斷肝動(dòng)脈變異有提示作用。
[Abstract]:Aim: to investigate the relationship between hepatic Zuo Ye transient perfusion abnormality and hepatic artery variation in order to improve the understanding of hepatic artery variation. Methods: from June 2015 to December 2015, 1275 consecutive cases of double phase enhanced upper abdomen CT were screened. All cases underwent arterial phase and portal phase double phase scanning according to the unified scanning scheme. To collect the patients with transient hepatic perfusion abnormalities with segmental distribution of hepatic Zuo Ye and to record the presence of hepatic artery variation and to analyze the correlation between hepatic artery variation and hepatic Zuo Ye transient perfusion abnormality according to Hiatt classification. Results 33 out of 1275 consecutive cases met the inclusion criteria, and hepatic Zuo Ye transient perfusion abnormalities were distributed in lobes or segments of liver. 30% 33% MSCT showed increased homogeneous density of hepatic Zuo Ye or 1-3 segments in arterial phase at the same time. The distribution of liver S3 was found in 2 cases (corresponding to vascular variation in Hiatt 鈪，
