  If you can do it, you can prepare the tools for aneurysm embolization.

  Interventional procedures to treat aneurysms use embolization.

Because the interventional operation is performed inside the blood vessel, it is impossible to clip the blood vessel from the outside of the blood vessel to cut off the aneurysm like a craniotomy, so the doctors thought of another method to eliminate the aneurysm: insert a microcatheter in the aneurysm cavity. , the tumor is filled and compacted like a puddle. As a result, blood flow can no longer enter the puddle (tumor) to increase the reservoir (tumor), and the tumor will naturally not burst (explode).

   This method can be said to have the same effect as the method of craniotomy to clip blood vessels to cut off the blood supply to aneurysms. It can also be imagined that the thinking logic of medical treatment of diseases is like engineering, which is a proper engineering operation.

   The neurosurgeons were not in a hurry to answer the nurse\'s inquiries and the suspicions of the cardiologists.

   Whether interventional embolization can be done or not depends on the number of aneurysms.

The advantage of    craniotomy is that as long as the doctor can find the aneurysm, and the doctor\'s hands are flexible enough, a small aneurysm may be removed for you.

  In the case of embolization, as I said before, you can\'t get in the diameter of the blood vessel with any tools, and absolutely nothing can be done. This is the limitation of interventional surgery, and it has not changed.

  What the **** is, the aneurysm is characterized by a small aneurysm that has a higher chance of bleeding.

  Aneurysm diameter less than 0.5 is a small aneurysm, larger than 0.6 is a common type, and larger than 2.5 is a giant aneurysm. Needless to say, huge tumors are also blood vessels that are easy to burst, and the risk of interventional embolization is also very high.

  In addition to the diameter of the tumor that limits embolization, the diameter of the tumor neck is another important condition for embolization. This means that what the surgeon uses to fill the tumor cavity is a tool called a coil, which is as soft as a spring and can be stretched and retracted. Such a thing is put into the tumor cavity. If the neck of the tumor is too large, it will be flushed by the blood inside, and it will easily fall out between the expansion and contraction inside, resulting in the failure of the operation.

   This is the reason why most MIAs choose microsurgery instead of interventional surgery. The conditions of the neurointerventional surgery framework are too restrictive. Like Fang Ze, doing neuro-interventional surgery is also a way of finding the way for neuro-microsurgery. That is, preoperative interventional examination to identify the patient\'s blood vessels, and identify the location and conditions of each tumor can provide convenience for setting the best surgical approach for craniotomy.

   Considering this, Deputy Director Lv emphasized with Zhai Yunsheng at the beginning that the National Association can also perform interventional surgery examinations. During the period, if there is a problem, the patient can be immediately transferred to the traditional operating room for surgery, which is reasonable.

   The phone in Deputy Director Lu\'s hand got through, and he went to the door and muttered. As if thinking, if you can\'t do it, you can\'t do it, if you can\'t pull the operating room on the third floor, the young doctors procrastinate and delay is just a waste of time.

  Xie Wanying stood across the glass, one could imagine Dr. Song\'s very conflicted and tangled mood in the operating room.

   The patient is a teacher from Dr. Song\'s alma mater in Beidu. Dr. Song definitely wants to help the teacher to solve the disease with the least harm. A craniotomy and only an intervention are far less likely to have side effects and harm to the patient.
