摘要

描述了一种使用电阻加热间质导管和传导传热治疗恶性脑肿瘤的热疗方法。与超声波或微波辐射等辐射热源相反，该系统通过放置在植入式导管中的电阻元件将电能直接转换为热量。热传递是通过传导和血液对流进行的。初步结果表明，导管周围的组织热分布是可预测的，给定固定的几何形状，对于肿瘤的热疗治疗是可行的

Interstitial hyperthermia using electrically heated catheters

A description is given of a hyperthermia method that uses resistively heated interstitial catheters and conductive heat transfer for treatment of malignant brain tumors. As opposed to radiant heat sources such as ultrasound or microwave radiation, this system utilizes simple direct conversion of electrical energy to heat via resistive elements placed in implantable catheters. Heat transfer occurs via conduction and blood convection. Preliminary results indicate that tissue thermal profiles surrounding the catheters are predictable, given a fixed geometry, and feasible for hyperthermia treatment of tumors.<>
