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.

多载体计算机断层扫描和血管造影对膈下动脉的形态学研究。
导言:膈下动脉是一条成对的动脉,其起源和走向各不相同,主要供应膈肌,也供应肾上腺、下腔静脉、胃和食道。本研究旨在通过多载体计算机断层扫描和血管造影术研究膈下动脉的起源和走向:材料和方法:通过 2449 次多载体计算机断层扫描分析了膈下动脉的解剖结构。对主要变化进行了三维重建。此外,在一组 28 张血管造影中对膈下动脉的走向和分支模式进行了描述性分析:结果:在 565 例(23.1%)病例中,膈下动脉作为共同主干出现,而在 1884 例(76.9%)病例中,膈下动脉作为单独血管出现。最常见的共同主干起源是腹腔主干(303 条;53.6%)和腹主动脉(255 条;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%):结论:膈下动脉的解剖结构非常多变。结论:膈下动脉的解剖结构非常多变,最常见的起源是腹腔干及其分支、腹主动脉和肾动脉。
