１概述肝肿瘤间质性激光固化疗法（Interstitiallasercoagula－tion，简称lLC）是在影像学导向下把激光光纤插入肿瘤内，利用激光产生的热效应造成肿瘤组织凝固性坏死而达到治疗的目的。１９８３年Bown犤１犦首次提出这一技术，１９８５年Hashimoto犤２犦报道了超声引导激光治 1 Overview Interstitial lasercoagula- tion (lLC) of hepatic tumors is the insertion of a laser fiber into the tumor under the guidance of imaging. The purpose of treatment is achieved by utilizing the thermal effect of laser to cause coagulation necrosis of the tumor tissue. In 1983, Bown 犤 1 犦 first proposed this technology, 1985 Hashimoto 犤 2 犦 reported ultrasound guided laser treatment
