恶性心包积液未产生心包填塞时可用外照射有效地治疗,这是一种易行且无害的治疗方法。用此方法连续治疗8例患者,其结果有6例患者心包渗出大为减轻。方法:8例患者临床诊断为恶性心包积液。全部病例均经超声心动描记进一步证实。3例于放疗前心包穿刺抽液,其中1例治疗期间多次抽液,2例细胞学阳性。放射冶疗在X线模拟机下设计,照射野包括整个心包腔。每两周在模拟机下定位一次以便随时缩野。采用4MVX线等剂量对穿照射,中线剂量
Malignant pericardial effusion can be effectively treated with external radiation when no pericardial tamponade occurs. This is an easy and harmless treatment. With this method, 8 patients were continuously treated. As a result, pericardial exudation was greatly reduced in 6 patients. Methods: Eight patients were diagnosed as malignant pericardial effusion. All cases were further confirmed by echocardiography. Three patients received pericardial puncture fluids before radiotherapy. One patient received multiple fluid withdrawals during treatment and 2 patients were cytologically positive. Radiation therapy was designed under an X-ray simulator, and the radiation field included the entire pericardial cavity. Every two weeks, it is positioned under the simulator for retraction. 4 MVX radiation dose equivalent to wear, midline dose
