Study on Roentgen Anatomy of Hepatic Artery For Interventional Therapy of Liver Cancer

Objective To study the roentgen anatomic morphology and variants of hepatic arteries for directing interventional therapy of liver cancer. Methods Routine celiac arteriography before transarterial embolization was underwent in 500 patients with liver cancer. In these cases with suspected anatomic variants of hepatic arteries, superior mesenteric arteriography or abdominal aortography was undertaken. The imaging of digital substraction angiography (DSA) was analyzed.Results The distribution of hepatic arteries was showed as typical in 364 cases (72.8%). The angle between proper hepatic and common hepatic arteries was obtuse in 62.4%, right in 13.0%, and acute in 24.6%. The variants of hepatic arteries were in 136 cases (27.2%), in which, the variants of common hepatic artery were in 30 cases (6.0%), the variants of proper hepatic artery in 32 cases (6.4%), the hepatic arteries originated from superior mesenteric artery in 56 cases (53.9%), and from left gastric artery in 29 cases (27.9%). Conclusion It can ensure the accuracy and complement of transarterial embolization for liver cancer to study the roentgen anatomic morphology and variants of hepatic arteries.
