【摘要】：目的:利用計(jì)算機(jī)斷層掃描血管造影(CTA)技術(shù)測(cè)量腹主動(dòng)脈角來評(píng)估內(nèi)側(cè)弓形韌帶綜合征的價(jià)值。背景:內(nèi)側(cè)弓形韌帶(MAL)綜合征或腹腔動(dòng)脈壓迫綜合征的特征在于臨床癥狀明顯,例如餐后上腹部疼痛,體重減輕,惡心,嘔吐和聽診雜音。這種情況是由內(nèi)側(cè)弓形韌帶壓迫腹腔干所引起的。在本研究中,我們主要在CT血管造影圖像中測(cè)量了中國(guó)人的下腹腔動(dòng)脈角度,以評(píng)估MAL綜合征的征象和其它如腹主動(dòng)脈粥樣硬化所導(dǎo)致壓狹窄的區(qū)別。材料和方法:從2015年1月1日到2015年7月31日我們分析了腹主動(dòng)脈CTA掃描的520例病人,306例男性,177例女性,37例因?yàn)闊o法評(píng)估的限制沒有用于我們的研究。腹腔動(dòng)脈的后壁和腹主動(dòng)脈的前壁構(gòu)成下腹腔動(dòng)脈角。我們標(biāo)記腹主動(dòng)脈前壁為基線,腹主動(dòng)脈的頭側(cè)和尾側(cè)分別標(biāo)記為0°和180°。在本組中,26列據(jù)報(bào)道具有小于30度的窄的狹窄腹角,并且具有不同程度的腹腔動(dòng)脈狹窄和受壓。結(jié)果:本組研究人群的平均下腹腔動(dòng)脈角度為(平均值±SD)52±16度,男性,310名,角度平均為51.05±17.75度;女性,183名,角度平均為50.2±16.74度。大多數(shù)患者(97.6%:481/493)的腹腔角小于90度或向下成角。本組的26名患有腹腔動(dòng)脈壓迫并管腔狹窄的患者中,10列由腹腔動(dòng)脈受到內(nèi)側(cè)弓形韌帶壓迫(18.40°±1.6°);9例由動(dòng)脈粥樣硬化引起腹腔動(dòng)脈狹窄(25.60°±2.5°),7例患者原因不明。結(jié)論:腹腔動(dòng)脈干夾角小于30度是內(nèi)側(cè)弓形壓縮綜合征導(dǎo)致的。
[Abstract]:Objective: to evaluate the value of medial arcuate ligament syndrome (MCLS) by measuring the angle of abdominal aorta with computed tomography angiography (CTAA).Background: the medial arcuate ligament syndrome or celiac artery compression syndrome is characterized by obvious clinical symptoms such as postprandial epigastric pain weight loss nausea vomiting and auscultation murmur.This condition is caused by medial arcuate ligament compression of the celiac trunk.In this study, we measured the angle of inferior celiac artery on CT angiography images in order to evaluate the difference between the signs of MAL syndrome and other pressure stenosis caused by abdominal aortic atherosclerosis.Materials and methods: from January 1, 2015 to July 31, 2015, we analyzed 306 patients with abdominal aorta CTA scan.The posterior wall of the celiac artery and the anterior wall of the abdominal aorta form the angle of the inferior celiac artery.The anterior wall of the abdominal aorta was labeled as the baseline, and the cephalic and caudal sides of the abdominal aorta were labeled 0 擄and 180 擄, respectively.In this group, 26 columns were reported to have narrow abdominal angle of less than 30 degrees, and varying degrees of abdominal artery stenosis and compression.Results: the mean angle of inferior celiac artery was (mean 鹵SD)52 鹵16 degree) in this study group, and that of male group was 51.05 鹵17.75 degree, and that of female group was 50.2 鹵16.74 degree.Most patients have an abdominal angle of less than 90 degrees or a downward angle.Ten of the 26 patients with celiac artery compression and lumen stenosis suffered from medial arcuate ligament compression and 9 patients with celiac artery stenosis caused by atherosclerosis 25. 60 擄鹵2. 5 擄of celiac artery stenosis were unknown for the reason of which the celiac artery was compressed by the medial arcuate ligament (18. 40 擄鹵1. 6 擄).Conclusion: the angle of celiac artery trunk is less than 30 degrees because of medial arcuate compression syndrome.
