INDWELLING BALLOON CATHETER FOR COMBINED POSTOPERATIVE INTRACAVITY PHOTODYNAMIC

一种留置气囊导管施放器， 装载近距离放射治疗或光动力治疗后的腔内 (PDT)在大约一周的时间内，已经开发了。 的 切除腔是稳定的，几何简单，以确保 要求辐射均匀性。 施用器被定位在 肿瘤切除后，在所产生的空腔的中心， 球囊膨胀以或多或少地填充空腔。 导管 通过皮肤带出并调整， 在头皮表面上方。 后装后行近距离放射治疗 10-12级分，直至72戈伊。 在一系列研究中， 72名患者 来自630 nm激光器的光能的转移是 发现高效和均匀，特别是如果气球是 充满了扩散液体。 一种新的治疗方案， 分次腔内近距离放射治疗与PDT联合应用 现在正在计划中。

An indwelling balloon catheter applicator which can be used for either intracavity after loading brachytherapy or photodynamic therapy (PDT) over a period of approximately one week has been developed. The resection cavity is stabilized, and geometrically simple to insure the uniformity of irradiation required. The applicator was positioned after tumor resection in the center of the resulting cavity and the balloon inflated to more or less fill the cavity. The catheter was brought out through the skin and adjusted so that 1-2 cm projected above the scalp surface. After loading brachytherapy was give in 10-12 fractions up to 72 gy. Few side effects were noted in a series of 72 patients. The transfer of light energy from a 630 nm Laser was found highly efficient and uniform especially if the balloon was filled with a diffusing liquid. A new treatment protocol employing the combination of both frationated intracavity brachytherapy and PDT is now being planned.
