N-丁基-2-氰基丙烯酸是一种粘合剂,与电离物质(如血液、内皮)接触后,几乎立即发生聚合。它属于液性栓塞剂,无全身毒性作用和致癌作用;粘度低,使之可经很细导管注入。作者对6例中肠类癌肝转移病人施行此疗法。6例皆有类癌综合征(潮红、腹泻等)。已切除原发癌、区域淋巴结和胆囊。肝转移存在于两个或两个以上不相邻肝段。尿中5-羟基吲哚乙酸(5-HIAA)水平比参照值上限高2倍。 方法为用CT和CT动脉门静脉造影术
N-butyl-2-cyanoacrylic acid is a binder that polymerizes almost immediately after contact with ionized materials such as blood and endothelium. It is a liquid embolic agent with no systemic toxicity and carcinogenic effects; its low viscosity allows it to be injected through very thin catheters. The authors performed this therapy on 6 patients with metastatic liver metastases. All 6 cases had carcinoid syndrome (flushing, diarrhea, etc.). Primary cancer, regional lymph nodes and gallbladder have been removed. Liver metastasis exists in two or more non-adjacent liver segments. Urinary 5-hydroxyindolylacetic acid (5-HIAA) levels were 2 times higher than the upper limit of the reference. CT and CT arterial portography
