摘要

本研究的目的在於以血管攝影評估肝動脈的變異性，並比較與其他研究的不同。回顧在1998年8月至2004年9月間405位病人的上腹部血管攝影影像，以鈴木(Suzuki)分類法分析肝動脈的變異性。單一肝動脈在405位病中人有283位(69.9%) ，雙重肝動脈有114位(28.1%)，多重肝動脈有8位(2.0%)。本研究中共找到17種變異型。由於肝臟周圍的血管走向複雜且變異性大，術前明確的血管影像是必要的。本研究可幫助上腹部手術或是介入性放射治療的術前評估，避免嚴重的併發症發生。

The purpose of this study is to evaluate the angiographic variations of hepatic arteries and to compare with the previous reports in literature in large series.
Records of 405 patients who underwent upper abdominal arteriography between Aug. 1998 and Sep. 2004 were reviewed. Hepatic artery anatomy was analyzed and classified according to Suzuki's classification. Single hepatic artery group included 283 of 405 cases (69.9 per cent). Double hepatic artery group included 114 cases (28.1 per cent). Multiple hepatic artery group included 8 cases (2.0 per cent). Seventeen patterns were identified in this study.
The complex vascular anatomy of the liver and the high incidence of normal vascular variants reinforce the need for accurate preoperative vascular imaging. This study is useful for planning surgical and radiological procedures of the upper abdomen and preventing some of the serious accidents.
