"Do you want to do it?" the nurse in the operating room asked the doctors.
If it can be done, the tools for aneurysm embolization can be prepared.
The interventional procedure used to treat aneurysms is embolization.
Since interventional surgery is performed inside the blood vessels, it is impossible to clamp the blood vessels from outside the blood vessels to cut off the blood flow to the aneurysm like craniotomy, so doctors have come up with another way to eliminate the aneurysm: put a microcatheter into the aneurysm cavity and fill the aneurysm tightly like filling a puddle. In this way, blood flow can no longer enter the puddle (tumor) to increase the reservoir (tumor), and the aneurysm will naturally not burst (burst).
This method can be said to be similar to the way of clamping blood vessels during craniotomy to cut off the blood supply to the aneurysm. It can also be imagined that the thinking logic of treating diseases in medicine is like engineering, which is a pure engineering operation.
The neurosurgeons were not quick to answer the nurse's questions and the cardiologist's suspicions.
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 tumor and his hands are flexible enough, even a very small aneurysm can be removed for you.
As for embolization, as I mentioned before, if your tools can't get into the blood vessel diameter, you can't do anything. This is the limitation of interventional surgery, and it has not changed.

The most damning thing is that the characteristic of aneurysms is that small aneurysms have a higher chance of bleeding.
Aneurysms with a diameter less than 0.5 are small aneurysms, those with a diameter greater than 0.6 are common aneurysms, and those with a diameter greater than 2.5 are giant aneurysms. It goes without saying that giant aneurysms are also very prone to bursting, and interventional embolization is also very risky.
In addition to the diameter of the tumor, which limits embolization, the diameter of the tumor neck is another important condition for whether embolization can be performed. This is because the surgeon uses a tool called a spring coil to fill the tumor cavity. As the name suggests, this thing is as soft as a spring and can stretch and shrink. If such a thing is placed in the tumor cavity, if the tumor neck is too large, it will be rushed by the blood flow inside, and it will easily slip out while stretching and shrinking inside, resulting in the failure of the operation.
This is why most MIAs choose microsurgery instead of interventional surgery. Neurointerventional surgery has too many restrictions. Like Fang Ze, many neurointerventional surgeries are also used to explore the path of neuromicrosurgery. That is, interventional examinations are performed before surgery to find out the patient's vascular conditions and the location and condition of each tumor, which can facilitate the setting of the best surgical approach for craniotomy.
Taking this into consideration, what 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 operation, the patient can be immediately transferred to the traditional operating room for surgery, which makes sense.
Deputy Director Lu got through on the phone and walked to the door, muttering to himself. He seemed to be thinking, if it can't be done, then it can't be done. If it doesn't work, go to the operating room on the third floor. The young doctors are just wasting time by delaying.
Xie Wanying was standing behind a glass and could imagine Dr. Song's conflicted and tangled mood in the operating room.
The patient was a teacher at Dr. Song’s alma mater, Beidu Hospital. Dr. Song certainly wanted to help his teacher cure his illness with minimal harm. There is a huge difference in side effects and harm to the patient between doing a craniotomy and just an intervention.
