Abstract

BACKGROUND

Swine are commonly used as a model to study congenital cardiovascular defects that occur in humans and these models have been both spontaneous and experimentally induced. Ventricular septal defect, patent ductus arteriosus, and atrial septal defect (ASD) are examples of experimentally induced models. Absence of caudal/inferior vena cava (CVC/IVC) with azygos/hemiazygos continuation is an uncommon vascular anomaly.

CASE REPORT

The vascular anomaly presented in this case report was an incidental finding on a pig that was evaluated for experimental percutaneous atrial septal defect creation and its closure using a percutaneous femoral vein approach. Absence of CVC/IVC was confirmed by venography and necropsy.

CONCLUSIONS

To the best of the investigators knowledge, this is the first report of absence of CVC/IVC with azygos/hemiazygos continuation in the swine.

摘要

背景

猪通常被用作研究人类先天性心血管缺陷的模型，这些模型既有自发性的，也有实验诱导的。室间隔缺损、动脉导管未闭和房间隔缺损（ASD）就是实验诱导模型的例子。下腔静脉/腔静脉缺如伴奇静脉/半奇静脉延续是一种罕见的血管异常。

病例报告

本病例报告中介绍的血管异常是一只猪在进行实验性经皮房间隔缺损造口术及其经股静脉经皮闭合术评估时偶然发现的。下腔静脉/腔静脉缺如通过静脉造影和尸检得到证实。

结论

据调查人员所知，这是首例在猪中发现下腔静脉/腔静脉缺如伴奇静脉/半奇静脉延续的报告。
