Laser-induced thermotherapy - an in situ ablation technique for the local treatment of irresectable colorectal liver metastases

摘要

Laser-induced thermotherapy (LITT) is a so called in-situ-ablation technique which is used for the treatment of liver tumors. Coagulation necrosis is induced by transmitting the laser irradiation via quartz fibers directly into the tumor tissue. LITT represents similary to surgical liver resection a local treatment form for liver metastases. The Nd-YAG laser (1064 nm) was used. The application system was placed percutaneously under open MRI control. On-line monitoring was done with MRI for evaluation of the postoperative follow-up we performed MRI-controls every 3 months.
