"Should we do it?" the nurse in the operating room asked the doctors.
If this is possible, the tools for aneurysm embolization can be prepared.
The interventional procedure used to treat aneurysms is embolization.
Since interventional surgery is performed within the blood vessels, it is impossible to clamp the blood vessels from the outside of the blood vessels to cut off the aneurysm like craniotomy. Therefore, doctors thought of another way to eliminate the aneurysm: placing a microcatheter in the aneurysm cavity.
, fill the tumor densely like filling a puddle. In this way, blood flow can no longer enter the puddle (tumor) and increase the reservoir (tumor), and the tumor will naturally not burst (explode).
This method can be said to be similar to the method of clamping blood vessels to cut off the blood supply to an aneurysm during craniotomy. It can also be imagined that the thinking logic of treating diseases in medicine is like engineering, which is a proper engineering job.
In response to the nurse's inquiries and the suspicions of the cardiology staff, the neurosurgeons were not in a hurry to give answers.
Whether interventional embolization can be performed certainly does not simply depend 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, he may be able to remove even a very small aneurysm for you.
When it comes to embolization, as I mentioned before, if you can’t get the tool into the diameter of the blood vessel, you absolutely can’t do anything. This is the limitation of interventional surgery, and it has never changed.
The most damning thing is that the characteristic of aneurysms is that small-sized aneurysms have a higher chance of bleeding.
Tumors with a diameter less than 0.5 are considered small aneurysms, those larger than 0.6 are ordinary aneurysms, and those larger than 2.5 are considered giant aneurysms. Needless to say, giant aneurysms are easily burst blood vessels, 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. The surgeon uses a tool called a spring coil to fill the tumor cavity, as the name says.
We all know that this thing is as soft as a spring and can stretch and contract. If such a thing is put into the tumor cavity, if the tumor neck is too big, it will be washed away by the blood flow inside, and it will easily slide out during the expansion and contraction, causing
The operation failed.
This is the reason why most MIAs choose microsurgery rather than interventional surgery in clinical practice. The framework of neurointerventional surgery has too many restrictions. Like Fang Ze, many neurointerventional surgeries also require neurosurgery.
Surgical pathfinding. That is, conducting interventional examinations before surgery to find out the patient's blood vessels and the location and condition of each tumor, which can provide convenience for setting the best surgical approach for craniotomy.
Considering this, Deputy Director Lu emphasized to Zhai Yunsheng at the beginning that the National Association can also perform interventional surgical examinations, and if any problems are found during the period, the patient can be immediately transferred to the traditional operating room for surgery, which is reasonable.
The phone in Deputy Director Lu's hand was connected, and he walked outside the door and muttered. He seemed to be thinking that if it can't be done, it can't be done. If it can't be done, it can be done in the operating room on the third floor. The young doctors' procrastination is just a waste of time.
Xie Wanying stood across the glass, and you can imagine Dr. Song's very conflicted and entangled mood in the operating room.
The patient is a teacher from Dr. Song's alma mater, Beidu. Dr. Song must have wanted to help the teacher solve the disease with minimal harm. There is a huge difference between a craniotomy and an intervention in terms of side effects and harm to the patient.
