"Should we proceed?" the nurse in the operating room asked the doctors.
If they could, they would prepare the tools for aneurysm embolization.
Interventional surgery for aneurysm treatment involves embolization.
Since interventional surgery operates within blood vessels, unlike open cranial surgery which cuts off blood supply to the aneurysm from outside the vessel, the doctors devised another method to eliminate the aneurysm: inserting a microcatheter into the aneurysm cavity and filling it tightly like filling a pit. This way, blood would no longer flow into the pit (aneurysm), expanding the reservoir (aneurysm), and the aneurysm would naturally not rupture (burst).
This method can be said to have a similar principle to open cranial surgery which clamps off the blood supply to the aneurysm, and it reflects the medical thinking process which is akin to engineering - a proper technical task.
