Abstract

Abstract Background 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. Objectives To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies. Methods 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. Results 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%. Conclusions The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.

2005-2021年92,833份ct扫描中罕见内脏动脉瘤的患病率
背景关于罕见内脏动脉瘤患病率的研究仍然很少,少数研究集中在这些动脉瘤的患者群体中,但对其在一般人群中的患病率知之甚少。目的探讨罕见内脏动脉瘤的ct扫描诊断及其他血管病变患者的随访情况。方法:本横断面研究首先访问了2005年1月至2021年7月在圣保罗市一家优秀私立医院进行的所有CAT扫描报告。使用预索引报告的软件程序搜索放射信息系统(RIS)数据库,以识别腹内动脉瘤患者的报告。结果共获取92,883例患者的CAT扫描报告。其中腹内动脉瘤2597例(2.795%),内脏动脉瘤937例(1.063%),其中罕见内脏动脉瘤158例(0.171%),男性多见于乳糜干(0.098%)、肠系膜上(0.033%)、左胃(0.010%)、胰-十二指肠(0.009%)、胃十二指肠动脉(0.005%)和胰弓(0.004%)。其他人群的患病率较低。其他研究结果显示,罕见的内脏动脉瘤与其他腹内动脉瘤合并的发生率为11.11%至66.67%。结论:在接受CAT扫描的大量人群中,罕见的内脏动脉瘤的患病率为0.171%,男性患者的患病率更高。
