Studies on the prevalence of rare visceral aneurysms are still scarce and the few studies that have focused on these aneurysms present prevalence rates in groups of patients with visceral aneurysms, but little is known about their prevalence in the general population.
To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies.
This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of São Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms.
CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%). Lower prevalence was found in other segments. Additional findings revealed concomitance of rare visceral aneurysms with other intra-abdominal aneurysms ranging from 11.11% to 66.67%.
The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.
关于罕见内脏动脉瘤患病率的研究仍然很少，少数关注这些动脉瘤的研究报告了内脏动脉瘤患者群体中的患病率，但对于其在普通人群中的患病率知之甚少。
评估在为其他血管病变患者进行诊断和随访的计算机断层扫描（CAT）中罕见内脏动脉瘤的患病率。
这项横断面研究首先获取了2005年1月至2021年7月在圣保罗市一家私立专科医院进行的所有CAT扫描报告。使用一个用于预索引报告的软件程序在放射信息系统（RIS）数据库中搜索腹内动脉瘤患者的报告。
获取了92883例患者的CAT扫描报告。其中，2597例（2.795%）显示有腹内动脉瘤，其中937例（1.063%）为内脏动脉瘤，包括158例（0.171%）罕见内脏动脉瘤，在男性患者中更为常见，且以下部位更为频发：腹腔干（0.098%）、肠系膜上动脉（0.033%）、胃左动脉（0.010%）、胰十二指肠动脉（0.009%）、胃十二指肠动脉（0.005%）和胰弓（0.004%）。在其他部位发现的患病率较低。其他发现显示罕见内脏动脉瘤与其他腹内动脉瘤的并存率在11.11%至66.67%之间。
在接受CAT扫描的大量人群中，罕见内脏动脉瘤的患病率为0.171%，男性受累更多。
