Abstract

INTRODUCTION

The inferior phrenic artery is a paired artery with a variable origin and course, primarily supplying the diaphragm, but also the suprarenal glands, inferior vena cava, stomach, and oesophagus. The aim of this study is to investigate the origin and course of the inferior phrenic arteries on multidetector computed tomography and angiography.

MATERIALS AND METHODS

The anatomy of the inferior phrenic artery was analysed on 2449 multidetector computed tomography scans. Three-dimensional reconstructions were made of the main variations. Additionally, the course and branching pattern of the inferior phrenic artery were descriptively analysed in a cohort of 28 angiograms.

RESULTS

In 565 (23.1%) cases the inferior phrenic arteries arose as a common trunk and in 1884 (76.9%) cases as individual vessels. The most common origins of a common trunk were the coeliac trunk (n=303; 53.6%) and abdominal aorta (n=255; 45.1%). The most common origins of the right inferior phrenic artery were the coeliac trunk (n=965; 51.2%), abdominal aorta (n=562; 29.8%) and renal arteries (n=214; 11.4%). The most common origins of the left inferior phrenic artery were the coeliac trunk (n=1293; 68.6%) and abdominal aorta (n=403; 21.4%).

CONCLUSION

The inferior phrenic artery has a very variable anatomy. The most common origins of the inferior phrenic artery are the coeliac trunk and its branches, the abdominal aorta, and the renal arteries.

摘要

介绍

膈下动脉是一对具有可变起源和走行的动脉，主要供应膈肌，但也供应肾上腺、下腔静脉、胃和食管。本研究旨在通过多排螺旋 CT 和血管造影来研究膈下动脉的起源和走行。

材料与方法

对 2449 例多排螺旋 CT 扫描的膈下动脉解剖结构进行分析。对主要变异进行三维重建。此外，在 28 例血管造影中对膈下动脉的走行和分支模式进行描述性分析。

结果

在 565 例（23.1%）中，膈下动脉以共同干起自，在 1884 例（76.9%）中以单独的血管起自。共同干最常见的起源是腹腔干（n=303；53.6%）和腹主动脉（n=255；45.1%）。右膈下动脉最常见的起源是腹腔干（n=965；51.2%）、腹主动脉（n=562；29.8%）和肾动脉（n=214；11.4%）。左膈下动脉最常见的起源是腹腔干（n=1293；68.6%）和腹主动脉（n=403；21.4%）。
