Interstitial hyperthermia of colorectal liver metastases with a US-guided Nd-YAG laser with a diffuser tip: a pilot clinical study.

摘要: Ultrasound (US)-guided interstitial hyperthermia performed with the neodymium yttrium aluminum garnet laser a diffuser tip involves placement of fiber in solid tissue followed by irradiation from within center tumor to be treated. The authors previously described development US-guided technique that permits simultaneous and temperature measurements, real-time US monitoring. With use dedicated modification bare fiber, it has proved possible produce spherical coagulations diameter comparable liver metastases clinical relevance. This was used 11 patients 16 colorectal metastases, 12 which were radically ablated. Real-time monitoring during treatment had positive predictive value 86% negative 100% judging final result. is feasible, effective, safe, but effect on patien...
