High frequency thermotherapy (HFTT) is an established palliative therapy for hepatic malignancies. An in vivo and in vitro trial examined the preconditions for the application of HFTT with liquid-cooled wet electrodes for minimally invasive palliation of head and neck tumors.
HFTT was applied with needle electrodes, cooled with isotonic saline solution, and a high-frequency generator (Elektrotom HiTT 106, Berchtold, Tuttlingen) to porcine tongue and narcotized, juvenile domestic pigs to the tongue and neck, and monitored in realtime by B-mode ultrasound.
The direction of spread of the hyperthermic zone is well observed using ultrasound. Determining the direction of spread is not possible with cooled-tip electrode needles. Severe complications were not observed during the application.
RFA with liquid-cooled needle applicators is not safely applicable for the therapy of head and neck tumors.
高频热疗(HFTT)是一种成熟的肝癌姑息治疗方法。一项体内和体外试验研究了使用液冷湿电极进行高频热疗以对头颈部肿瘤进行微创姑息治疗的应用前提条件。
使用针电极进行高频热疗,针电极用等渗盐溶液冷却,并使用高频发生器(Elektrotom HiTT 106,Berchtold,图特林根)作用于猪舌以及麻醉的幼年家猪的舌部和颈部,并通过B型超声进行实时监测。
使用超声可以很好地观察到热疗区的扩散方向。对于冷却尖端电极针,无法确定扩散方向。在应用过程中未观察到严重并发症。
使用液冷针式施药器进行射频消融术对头颈部肿瘤治疗并不安全适用。
