文档介绍：DSA在直肠癌肝转移的临床应用研究
(作者:___________单位: ___________邮编: ___________)
【摘要】目的:通过分析直肠癌肝转移瘤的 DSA 表现,明确转移瘤的血供特点,指导介入治疗。方法:30例直肠癌肝转移患者,介入治疗前进行DSA造影检查,分析DSA图像上病灶位置、数目和血供情况。并收集18例原发性肝癌进行对照比较。结果:30例直肠癌肝转移瘤中,转移到肝左叶7例(%),肝右叶12例(%),同时累及左、右肝叶11例(%),瘤体转移至肝左、右叶及肝两叶三个部位的分布频度差异无统计学意义()。单发及少发结节(3个以下转移灶)9例(%),多发结节(3个及3个以上转移灶)21例(%),两者差异有统计学意义()。富血供瘤8例(%),乏血供瘤22例(%),两者差异有统计学意义()。结论:直肠癌肝转移瘤以多发性乏血供瘤为主,DSA造影有助于其与原发性肝癌相鉴别,并能为介入治疗提供依据。

Abstract Objective:To analyze the digital substraction angiography(DSA) imaging features for hepatic metastases from rectal cancer and identify characteristics of the blood supply of hepatic metastases to guide interventional :Thirty cases with hepatic metastases were examined with DSA before interventional therapy to analyze the location,numbers,and blood supply of 18 cases with primary hepatic carcinomas served as :In 30 cases, metastases in the left hepatic lobe were
in 7 cases (%), in the right hepatic lobe in 12 (40%),and in the left and right hepatic lobe in 11 (%),with no significant difference in the distribution rate of metastases ().Metastases were hyponodules in 9 cases (30%) compared with that were mutinodules in 21 (70%,).Metastases with rich blood supply were in 8 cases(%) compared with that with insufficient b
