Situs inversus totalis is a rare condition of visceral transposition in thoracic and abdominal cavities. Computed tomography (CT)-based morphometric analysis of the cardiovascular system prior to the surgery helps to describe vessel topography and size, choose the right surgical insertion site, avoid vessel trauma, and prevent hemorrhage during surgical intervention. We present a case report of situs inversus totalis detected incidentally in a 74-year-old male with the acute abdominal syndrome. Appropriate detailed aorta measurements are used to choose an adequate size of the aortic prosthesis during open surgical repair or endovascular aneurysm repair. An accurate assessment of the vessels on CT scans assists in consideration of the catheter diameter and the most reliable cannulation site. Vessel size correlates with morphological conditions (kinking, stenosis, occlusion), which may be considered a risk of organ malperfusion. The anatomical analysis prior to surgery in different anatomical variations may ensure patient safety and predict complications.
全内脏反位是一种胸腔和腹腔内脏器官转位的罕见情况。术前基于计算机断层扫描（CT）的心血管系统形态计量分析有助于描述血管的形态和大小，选择合适的手术入路部位，避免血管损伤，并防止手术干预期间出血。我们报告一例74岁男性急性腹部综合征患者偶然发现全内脏反位的病例。在开放手术修复或血管内动脉瘤修复过程中，使用适当详细的主动脉测量数据来选择合适尺寸的主动脉假体。CT扫描对血管的准确评估有助于考虑导管直径和最可靠的插管部位。血管大小与形态学状况（扭结、狭窄、闭塞）相关，这些状况可能被视为器官灌注不良的风险因素。针对不同解剖变异进行术前解剖分析可确保患者安全并预测并发症。
