|
【临床中医学论文】【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(23.3%),肝右叶12例(40.0%),同时累及左、右肝叶11例(36.7%),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(P>0.05)。单发及少发结节(3个以下转移灶)9例(30.0%),多发结节(3个及3个以上转移灶)21例(70.0%),两者差异有统计学意义(P<0.05)。富血供瘤8例(26.7%),乏血供瘤22例(73.3%),两者差异有统计学意义(P<0.05)。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。 【关键词】 直肠癌肝转移瘤 原发性肝癌 DSA 鉴别诊断 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 therapy.Methods:Thirty cases with hepatic metastases were examined with DSA before interventional therapy to analyze the location,numbers,and blood supply of metastases.Other 18 cases with primary hepatic carci
