什么是激光消融手术?
Laser ablation is one of the best alternatives to invasive procedures like craniotomies (temporarily removing a piece of the skull to access the brain during surgery).
大发娱乐的目标是：
- reduce the number 和 severity of seizures or cure 癫痫 完全,
- 改善以下症状 treatment-resistant obssessive-compulsive disorder (OCD),
- 破坏（或切除）肿瘤.
Laser ablation is extremely effective for treating seizures or 强迫症的症状 in patients who do not get better after taking medications.
激光消融手术的最佳候选者
在选择手术之前, your doctor will review your medical history 和 conduct image testing to learn more about your condition. Most patients will not be considered for surgery until they try medications or other types of treatments.
The patients who benefit most from laser ablation will have:
- uncontrolled seizures after trying other therapies, medication, dietary changes,
- 脑部肿瘤 或者导致癫痫发作的异常组织，
- seizures deep inside the brain where doctors cannot operate using traditional surgery,
- 难治性强迫症,
- small lesions or very specific areas where seizures occur,
- hypothalamic hamartoma (tumors that form during fetal development), or
- tuberous sclerosis (a rare disease that causes tumors or growths in the brain),
- mesial temporal lobe 癫痫 (the most common type of 癫痫), or
- cortical dysplasia (brain abnormalities that form before a child is born).
好处 & 激光消融手术的风险
The benefits of laser ablation surgery include:
- a less invasive 和 safer procedure than an open brain craniotomy (temporarily removing a piece of the skull to access the brain for surgery),
- a lower chance of damaging healthy tissues during surgery,
- 手术时间更短，
- smaller incisions 和 holes in the bone to insert the laser,
- no need to shave the surgical site (patients keep their hair),
- 减少手术后的疤痕和疼痛，
- an ability to treat areas deep in the brain that a surgeon cannot reach,
- shorter hospital stay 和 quicker recovery,
- fewer complications than traditional craniotomies.
然而, laser ablation does have some risks. While they are rare, some reported complications include:
- 缩小视野,
- 脑部出血，
- 神经损伤，以及
- 感染，这是任何手术都有的风险.
Talk to your doctor about the risks for you or your child before deciding which surgery is best.

激光消融的原理
Laser ablation uses lasers to surgically remove tumors or the part of your brain that causes seizures or 强迫症的症状. 病人 who get laser ablation surgery will still be under general anesthesia (put to sleep) during the procedure. Your surgeon will make a small incision (cut) in the skull (about the size of a pencil) to place a guided laser probe into the brain. 你的手术小组将使用 核磁共振成像 标出他们要去的确切地点. This method of using lasers 和 MRI mapping targets a seizure location with pinpoint accuracy.
一旦他们找到了地点, the neurosurgeon will use lasers to target the spot in the brain where seizures occur. The laser will convert to thermal energy (heat) inside your brain 和 destroy the specific brain cells that cause seizures or 强迫症的症状.
在手术过程中, your team will monitor the temperature in nearby areas of your brain with a computer. Your spinal fluid keeps those areas cool to prevent damage to healthy brain tissue outside of the seizure location. 一旦手术完成, your surgeon will close the small hole he or she made in the bone 和 the skin with a single stitch. You will spend only one to two nights in the hospital to recover after surgery.
手术时间
A patient will typically be under anesthesia for four to five hours during laser ablation surgery. 然而, most of this time is spent on MRI scans 和 planning to verify the exact location 和 prepare for the procedure. The actual laser portion takes around one hour.
激光消融成功率
癫痫成功率
在很多病人中, this surgery will successfully stop their seizures; however, 你可能需要不止一次手术. Some people still have seizures after brain surgery or seizures that come back later. 继续看你的 神经学家 和 癫痫 care team after surgery to ensure the best recovery 和 outcome.
难治性强迫症的成功率
Surgical treatments for 难治性强迫症 have shown to be effective in 60-70% of patients. This means there was at least a 35% reduction in disease severity, allowing these patients to go back to their active life 和 work.
激光消融手术恢复
It takes about two weeks to recover fully 和 resume normal activity at home after leaving the hospital. 然而, some people may require more recovery time 和 your surgical team will give you a recovery plan that takes your health 和 medical history into account.
