【摘要】：目的:利用计算机断层扫描血管造影(CTA)技术测量腹主动脉角来评估内侧弓形韧带综合征的价值。背景:内侧弓形韧带(MAL)综合征或腹腔动脉压迫综合征的特征在于临床症状明显,例如餐后上腹部疼痛,体重减轻,恶心,呕吐和听诊杂音。这种情况是由内侧弓形韧带压迫腹腔干所引起的。在本研究中,我们主要在CT血管造影图像中测量了中国人的下腹腔动脉角度,以评估MAL综合征的征象和其它如腹主动脉粥样硬化所导致压狭窄的区别。材料和方法:从2015年1月1日到2015年7月31日我们分析了腹主动脉CTA扫描的520例病人,306例男性,177例女性,37例因为无法评估的限制没有用于我们的研究。腹腔动脉的后壁和腹主动脉的前壁构成下腹腔动脉角。我们标记腹主动脉前壁为基线,腹主动脉的头侧和尾侧分别标记为0°和180°。在本组中,26列据报道具有小于30度的窄的狭窄腹角,并且具有不同程度的腹腔动脉狭窄和受压。结果:本组研究人群的平均下腹腔动脉角度为(平均值±SD)52±16度,男性,310名,角度平均为51.05±17.75度;女性,183名,角度平均为50.2±16.74度。大多数患者(97.6%:481/493)的腹腔角小于90度或向下成角。本组的26名患有腹腔动脉压迫并管腔狭窄的患者中,10列由腹腔动脉受到内侧弓形韧带压迫(18.40°±1.6°);9例由动脉粥样硬化引起腹腔动脉狭窄(25.60°±2.5°),7例患者原因不明。结论:腹腔动脉干夹角小于30度是内侧弓形压缩综合征导致的。
[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 掳and 180 掳, 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 卤SD)52 卤16 degree) in this study group, and that of male group was 51.05 卤17.75 degree, and that of female group was 50.2 卤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 掳卤2. 5 掳of celiac artery stenosis were unknown for the reason of which the celiac artery was compressed by the medial arcuate ligament (18. 40 掳卤1. 6 掳).Conclusion: the angle of celiac artery trunk is less than 30 degrees because of medial arcuate compression syndrome.
