Abdominopelvic vascular structures are exposed to be compressed by adjacent organs or might cause compression of the adjacent hollow viscera. Most of these conditions are asymptomatic and they are detected on imaging incidentally. However, when they are symptomatic, they can lead to a variety of uncommon syndromes in the abdomen and pelvis. Aim of the study was to assess the prevalence of incidental abdominopelvic vascular compressions on computed tomography.
A retrospective cross-sectional study was conducted. All the CT was performed using 64 slice machine. All computed tomography scan of the abdomen between January and April 2019 were evaluated. Data were collected by evaluating abdominal Computed Tomographic scans from Picture archiving and communication system (PACS). Statistical analysis was performed by using SPSS version 25.0 software.
Out of 623 multi detector abdominopelvic computed tomography (MDCT) performed between January 2019 and April 2019; a total of 513 (N = 513) patients were included in the study. This study group comprised of 277 (54 %) females and 236 male (46%) patients. Mean age was 38 ± 20 (mean ± SD). We identified 35(6.8%) participants with imaging features of Superior mesenteric artery (SMA) compressions and a 34(6.6%) with imaging features of nutcracker phenomenon. The celiac artery was compressed by median arcuate ligament (MAL) in 22(4.3%) of them.
Incidentally detected intraabdominal vascular compressions are common to asymptomatic patients. This result emphasizes that, vascular compression syndromes diagnosis should not be made on imaging alone.
腹盆腔血管结构可能会受到邻近器官的压迫，也可能导致相邻空腔内脏器受压。大多数情况下这些情况是无症状的，并且是在偶然进行影像学检查时发现的。然而，当它们出现症状时，可能会导致腹部和盆腔出现各种罕见的综合征。本研究旨在评估 CT 偶然发现的腹盆腔血管受压的发生率。
这是一项回顾性的横断面研究。所有 CT 检查均采用 64 排螺旋 CT 机完成。对 2019 年 1 月至 4 月期间进行的所有腹部 CT 进行评估。通过从图像存档与通讯系统（PACS）评估腹部计算机断层扫描来收集数据。使用 SPSS 版本 25.0 软件进行统计分析。
在 2019 年 1 月至 4 月期间进行的 623 例多排螺旋 CT 腹部平扫和增强检查中；共有 513 例（N = 513）患者纳入本研究。该研究组包括 277 例（54%）女性和 236 例男性（46%）。平均年龄为 38 ± 20 岁（均数 ± 标准差）。我们发现 35 例（6.8%）参与者有肠系膜上动脉（SMA）受压的影像学特征，34 例（6.6%）有胡桃夹现象的影像学特征。22 例（4.3%）患者腹腔干动脉受压是由正中弓状韧带（MAL）所致。
在无症状患者中偶然发现的腹腔内血管受压是很常见的。这一结果强调，血管压迫综合征的诊断不应仅基于影像学检查。
