准备伽玛刀治疗
The Gamma Knife is an advanced radiation treatment for small to medium primary or metastatic brain tumors异常血管形成称为 动静脉畸形, epilepsy, 三叉神经痛, a nerve condition that causes chronic pain, and other neurological conditions.
尽管它的名字叫“刀”,但它并不是一把刀. 它精确地传递一个单, 非常精细地聚焦, 对目标的高剂量辐射, 同时对周围组织几乎没有伤害.
伽玛刀治疗包括六个基本步骤:
- Preparation
- 应用框架
- Imaging studies
- 治疗计划
- 伽玛刀治疗
- Recovery
Preparation
You will visit the hospital one to two days before the Gamma Knife procedure for blood tests 并与进行手术的十大赌博平台排行榜见面. A schedule of appointments will be sent to you by mail from the UCSF Gamma Knife Radiosurgery Program. Please let us know if you have had any of the required tests performed in the past year. 如果是这样,请携带测试结果的副本.
你将会见一位神经外科十大赌博平台排行榜和一位放射肿瘤学家. 每个十大赌博平台排行榜都会记录你的病史, perform a physical examination and obtain your consent to perform the Gamma Knife procedure. You will have an opportunity to tour the 伽玛刀治疗 room and ask questions about the procedure and expected results. We recommend that you write down your questions before your appointment to ensure you don't forget them.
治疗前一晚
如果你住在旧金山地区以外, 请住在加州大学旧金山分校医疗中心附近的酒店或宾馆. 2点以后不吃东西吗.m. Take your regular medications the day before and the morning of the procedure with a small amount of water.
治疗的早晨
Typically, you will be in the hospital only for the day of the procedure. 带上你的药物,这样你就可以根据需要在白天服用. 提供拖鞋袜和长袍. Please bring reading materials, music CDs or tapes, or a video to watch in the patient waiting area. Remember to leave your valuables, such as jewelry and large sums of cash, at home.
请到帕那萨斯大街505号的十大赌博平台排行榜. 早上6点到6点半.m. 去M-104J室的门诊手术等候区. 这个房间位于一楼大厅的右边. 护送人员将在那里与您会面. 等候区电话是(415)353-1626.
有人会带你去四楼的术前区. 家人或朋友可以陪你去. You will be asked to put on a hospital gown and a nurse will start an intravenous (IV) line through which you will receive fluids and a mild sedative during the procedure. The same IV is used to administer the contrast agent for your imaging studies. 如果你有假牙,你可以戴假牙. 请摘下眼镜和其他个人物品.
应用框架
The stereotactic frame is placed on your head while in a sitting position. 它适用于术前区域. The frame acts as a guide to find the exact location of the brain lesion. 你的头必不剃光. Your neurosurgeon will inject local anesthesia into your scalp in four places or "pin sites" where the frame will be attached. You may feel some brief discomfort during these injections and can ask for more medication to help you relax. You may feel some pressure after the head frame is attached, but this will subside. 你可以在固定框架后入睡.
Children are given general anesthesia before the frame is attached and remain asleep during the Gamma Knife procedure. A neuro-anesthesiologist gives the anesthesia and stays with your child throughout the procedure.
成像研究
在手术之前,你会接受影像学检查,比如 核磁共振成像 or 计算机断层扫描 scans or 脑血管造影. 在学习期间, we ask that the family member or friend return to the outpatient surgical waiting area. He or she can return after the imaging studies are done, prior to treatment. These studies help your doctors locate the brain lesion as it relates to the stereotactic frame.
治疗计划
影像学检查完成后, 在你的治疗计划期间,你将被带到候诊室. A videocassette player is available in the room, if you would like to bring a video. 如果您的针刺部位引起疼痛,请通知您所在单位的护士. He or she will call the Gamma Knife nurse, who will inject the pin sites with local anesthesia.
治疗计划 will take one to several hours depending on the size and shape of the target area. Your doctors will locate the brain lesion in three dimensions using computer software and data from your imaging studies. The position of your head in the helmet, radiation dose and length of treatment will be decided.
伽玛刀治疗
在十大赌博平台排行榜计划好你的治疗方案之后, you will be brought to the Gamma Knife area and placed on the treatment bed, 仰面躺着. Your blood pressure and pulse will be monitored throughout the treatment. The stereotactic frame will be fitted into a steel helmet and fixed in position. The doctors will leave the room when treatment is ready to begin and will observe you on video camera and talk with you by intercom.
治疗开始后,你将进入一个大的屏蔽球体. The steel helmet will interlock with another helmet inside the sphere that holds the source of radiation. 只有你的头会在球里. 在治疗期间,你不会感觉到、看到或听到任何不寻常的东西. 每次“注射”的辐射将持续一到几分钟. 在每个镜头结束时, the steel helmet unlocks from the inner helmet and the bed moves out of the sphere. For most cases the automatic patient positioning system moves you to the next position. In some cases, it is necessary for the doctors to manually position you in the helmet for each shot. The entire treatment may consist of one or several shots of radiation.
The entire procedure from frame application until treatment completion usually takes most of the day.
Recovery
After treatment, the stereotactic frame is removed and you will be transferred to a recovery room. You may have a headache, and not having eaten all day may add to your discomfort. 如有需要,将提供治疗头痛的药物. 我们会对你进行监测,包括血压和脉搏. 在大多数情况下,患者在同一天晚些时候出院. 你可以恢复正常的活动和饮食,只要你觉得可以.
Children are moved to the pediatric recovery room where parents can stay with their child until ready for discharge. 大多数孩子在一天结束后回家.
我们将在您出院前提供后续指导. 如果你需要更多的药物,你会收到处方. If you are given any medications on the day of treatment, you must arrange a ride home. 如果您在手术后有任何疑虑或问题, 请致电(415)353-9325给伽玛刀护士打电话.
