Radio-Frequency Ablation (RFA) Offers New Hope for Patients with Inoperable Kidney and Liver Tumors射频消融（ RFA ）的提供了新的希望，为患者无法操作，肾脏和肝脏肿瘤
A new, non-surgical procedure called radio-frequency ablation (RFA) offers new hope for patients with inoperable kidney and liver tumors.一个新的，非手术的程序，所谓的射频消融（ RFA ）的提供了新的希望，为患者无法操作，肾脏和肝脏肿瘤。 RFA uses heat to “vaporize”射频消融用途热“蒸发”
Peter J. Julien MD, chief of Thoracic Imaging and director of the Radio-frequency Ablation Program at Cedars-Sinai Medical Center’s S. Mark Taper Foundation Imaging Center, Julien, an interventional radiologist, is one of the pioneers of RFA.彼得j.朱利安，海事处，行政胸部影像学和主任的射频消融计划在雪松-西奈医学中心的第马克锥度的基础成像中心，朱利安，介入放射科，是先驱之一，射频消融。
The procedure requires only local anesthesia and avoids the scars and complications associated with traditional open surgery.程序，只需要局部麻醉，避免了瘢痕和相关并发症与传统开放性手术治疗。 Because RFA involves no cutting, it is also a viable option for individuals previously thought to be too old or sick to withstand surgery.射频消融，因为不涉及切割，这也是一个可行的选择，为个人以前被认为太老了或生病的承受手术。
During RFA, an interventional radiologist carefully guides an ablation needle into the center of the tumor using imaging techniques such as ultrasound or CT scan.在射频消融，介入放射仔细指南一消融针进入中心的肿瘤使用成像技术，如超声或CT扫描。 The probe is connected to a radio-frequency generator that delivers alternating electrical current (radio-frequency energy) to the tumor producing heat up to 140 degrees Fahrenheit.探头连接到无线电频率发生器提供交流电流（无线电频率能量）的肿瘤产生热量高达140华氏度。 This causes cancerous cells to shrink and die, but healthy tissue is spared because the probe cools as it is removed.这会导致癌细胞萎缩及模具，但健康的组织是不遗余力，因为探头的冷却，因为它是移除。
Typically, surgical removal of kidney tumors (nephrectomy), which has been the standard of care for kidney cancers, results in hospital admissions of 7 to 10 days and postoperative recovery time of 6 to 8 weeks.通常情况下，手术切除肾肿瘤（肾） ，这一直是标准的护理服务，为肾脏癌，结果在入院的7到10天及术后恢复时间6至8周。 By comparison, RFA is not only minimally invasive with a short recovery time, but it also allows for the kidney to be preserved.相比之下，射频消融不仅是微创与在短期内恢复时间，但它也允许为肾予以保留。 RFA also avoids postoperative complications such as pain, pneumonia, injury to the organs and scars.射频消融也避免了术后并发症如疼痛，肺炎，损伤的器官和伤疤。
Although the procedure is new and more data are needed, it appears to result in survival rates that are comparable to those of radical or partial nephrectomies.虽然程序是一个新的和需要更多的数据，这似乎结果在生存率是相若的激进或部分nephrectomies 。 Beyond that, it may well offer hope for patients with liver cancer.除此之外，它很可能提供了希望，为肝癌患者。
