The window of time suitable for solving partial vascular embolism and aneurysms with interventional surgery is early detection.
If detected late, reaching the severity of large-area cerebral infarction or major aneurysm hemorrhage, interventional surgery is not an indication at all.
The cerebral vascular system, in terms of number or composition paths, is far more complex than the cardiovascular system, making interventional procedures much more difficult than cardiovascular ones, and the vessels that can truly be operated on are limited. As previously mentioned, interventional surgery on the retinal artery is simply inaccessible.
