نظرة عامة

في جراحة الدماغ بمساعدة الحاسوب، يستخدم الجرَّاحون تقنيات التصوير مثل التصوير بالرنين المغناطيسي (MRI)، والتصوير بالرنين المغناطيسي في أثناء العملية، والتصوير المقطعي المحوسب (CT) والتصوير المقطعي بالإصدار البوزيتروني (PET)، لإنتاج نموذج ثلاثي الأبعاد للدماغ. قد يتم إجراء ذلك قبل الجراحة أو خلالها في بعض الحالات.

يسمح هذا النموذج لجرَّاح الدماغ (جرَّاح الأعصاب) بالتخطيط للطريقة الأكثر أمنًا لعلاج حالتك. أثناء الجراحة، يوجه نظام الحاسب الآلي الجرَّاح بدقة إلى المنطقة (المناطق) في الدماغ التي تحتاج إلى علاج.

لماذا يتم إجراء ذلك

تُستخدم جراحة الدماغ بمساعدة الحاسوب لعلاج مجموعة متنوعة من الحالات التي تصيب الدماغ، بما في ذلك: أورام الدماغ ومرض باركنسون والرعاش مجهول السبب والصرع والتشوهات الشريانية الوريدية.

إذا كنت مصابًا بورم في الدماغ، فقد يجمع الجراح بين الجراحة بمساعدة الحاسوب وجراحة الدماغ أثناء اليقظة.

كما يستخدم جراحو الأعصاب في مايو كلينك أساليب بمساعدة الحاسوب لعلاج أورام الدماغ والتشوهات الشريانية الوريدية وألم العصب ثلاثي التوائم وحالات أخرى بحزم إشعاعية مركزة بدقة باستخدام الجراحة الإشعاعية التجسيمية للدماغ.

إذا كنت مصابًا بصرع أو مرض باركنسون أو الرعاش مجهول السبب، فقد تنطوي الجراحة بمساعدة الحاسوب على تنبيه عميق للدماغ. قد يستخدم الجراحون التصوير بالرنين المغناطيسي للمساعدة في رسم خريطة دماغك ورسم موضع المسارات الكهربائية.

المخاطر

Computer-assisted brain surgery helps to lower the risks of surgeries. By creating a 3D model of your brain, your neurosurgeon can plan the safest way to treat your condition. Computer assistance also helps guide your surgeon to the precise areas of the brain that need treatment. However, every surgery carries some risk.

Stereotactic radiosurgery has few risks, and potential side effects are often temporary. They may include feeling very tired, and soreness and swelling at the treatment site. Side effects also may include scalp irritation. Rarely, brain changes may occur months after the surgery.

Deep brain stimulation also has risks, including infection, bleeding, seizures and stroke.

If part of the skull is removed for surgery, potential risks include bleeding, swelling or infection.

كيف تستعد؟

Follow the instructions from your healthcare team about what to do in the days and hours before brain surgery. You may need to stop certain medicines before surgery.

For example, blood-thinning medicines slow the blood-clotting process. These medicines can increase the risk of bleeding. Talk to your healthcare team about whether you need to stop taking a blood-thinning medicine before surgery and for how long.

ما يمكن أن تتوقعه

What happens during computer-assisted brain surgery depends on the type of surgery you're having. A medicine that puts you in a sleep-like state, known as general anesthesia, often is used in computer-assisted brain surgery. If you're having awake brain surgery, you're given medicines to feel relaxed and block pain but that keep you awake. This allows you to interact with the surgery team to maximize safety during surgery.

Sometimes a piece of skull is removed to operate on the brain. In other surgeries, such as stereotactic radiosurgery, no cuts are made. Instead, radiation is aimed at the area of the brain needing treatment.

Your neurosurgeon may take imaging scans during surgery, known as intraoperative MRI or CT using a portable CT scanner. The imaging machine used to take the images may be in the operating room and brought to you for the imaging. Or it may be in a room next door and you're brought to the machine for the images.

النتائج

Computer-assisted brain surgery helps surgeons more precisely plan and conduct brain surgeries. When brain surgery is more precise, it leads to better outcomes and fewer complications.

Using imaging during surgery, known as intraoperative MRI or CT, helps neurosurgeons take into account changes to the brain that occur during surgery. For example, the brain can shift during surgery. Taking images during surgery helps to make the surgery more precise. Intraoperative imaging also alerts surgeons to complications so that they can be addressed quickly.

Some research has found that using intraoperative MRIs helps surgeons more completely remove a tumor or damaged tissue. Computer-assisted brain surgery also allows more healthy tissue to be spared while targeting only the brain tissue that's being operated on.
