Hepatic artery embolization (HAE), also known as trans-arterial embolization (TAE), is one of several medical methods to treat primary liver tumors or metastases to the liver. The embolization therapy can reduce the size of the tumor, and decrease the tumor's impact such its hormone production, effectively decreasing symptoms. The treatment was initially developed in the early 1970s.〔 The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked.〔 In practice, hepatic artery embolization occludes the blood flow to the tumors,〔 achieving significant tumor shrinkage in over 80% of people.〔 Shrinkage rates vary.〔〔 ==Background== The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked.〔 In practice, hepatic artery embolization is an option if the neoplastic growth is mainly within the liver.〔 By occluding the blood supply to the tumors,〔 achieving significant tumor shrinkage in over 80% of people.〔 Shrinkage rates vary.〔 The therapy can effectively decrease symptoms by reducing the size of the tumor, or by decreasing the tumor's impact, for example by decreasing the tumor's production of hormones.〔 Primary liver tumors, metastatic neuroendocrine tumors to the liver〔 and other metastases to the liver〔〔 may be considered for therapy directed via the hepatic artery. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hepatic artery embolization」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
