The anterior choroidal artery is a relatively magical artery in neurosurgery.

First of all, in human embryos, the cerebral blood vessels are all from the internal carotid artery. The internal carotid artery emits two blood vessels outside the ocular artery, one of which is the anterior choroidal artery.

Interestingly, such an artery that seems to be very important, chooses to degenerate after humans continue to grow. Therefore, some people start from the middle cerebral artery and posterior communication artery, while most people start from the lateral wall of the internal carotid artery.

A degenerated artery is certainly not as thick as the aortic trunk growing into a tree trunk, but has a long and thin stroke and is more likely to become obstructed. Is this degenerated artery completely unimportant? Otherwise, why is it degenerated?

According to human research, the degenerate parts of the human body have special significance for its existence. No part of the human body can be said to be completely useless. The same is true for the anterior choroidal artery. It provides blood basal ganglia, blood-supporting tract, blood-supporting cyst and other important brain tissue areas such as the hippocampus area of ​​the brain.

If it is ischemia and does not provide support with the anastomotic branch of the posterior choroidal artery, the patient will experience symptoms such as hemiplegia and blindness.

The consequences of ischemia are terrible, and bleeding must be even more terrible.

Is there aneurysm in the anterior choroidal artery? The number of long ones can account for a few percent of the incidence of aneurysms, which cannot be said to be rare.

During the first whole-cerebrovascular examination, the doctor had a illuminated the anterior choroidal artery. However, it was not an arterial trunk, it was very small, and the blood vessels displayed by the DSA image were shallow, dark, unclear and not conspicuous.

The doctor glanced at it and saw that there was no ischemia in the part that showed no bloating.

But now the microcatheter in the hand that was replaced can quickly enter the anterior choroidal artery smoothly and quickly, indicating that the diameter of this artery has become larger?

According to common sense, the anterior choroidal artery should have a small diameter. Its larger diameter may indicate a problem, and it will become an aneurysm.

The aneurysms of the anterior choroidal artery are often very small in size. Even so, as long as the aneurysms in this place become slightly larger, the size is larger like an aneurysms in a reservoir, and they can easily control the fluctuations of the anterior choroidal artery with a small diameter below that accommodates small water flow.

Two-dimensional image images are indeed easy to fool people in the early stages of lesions. Cerebrovascular images happen to be rich in bifurcations. If you look closely at the blood vessels, you can say that they are dense and intertwined, like a mess.

If a doctor relies on the existing knowledge base of medicine to calculate, it is better to rely on the feel to be faster and more accurate. The feel and reflexes are purely natural, so there is no need to worry about it or calculate it.

All those who were waiting and watching the operation could only think in their hearts: Cao Yong is winning another one.

When the microcatheter enters a certain point, the spring coil is placed and the total embolization is complete. Then check the ocular artery, and an opportunity arises...

Half an hour later, the operation ended.

The nurse uses a lathe to take the patient back to the ward.

"Director Zhai." Deputy Director Lu said that he accompanied Zhai Yunsheng, the great expert, to prepare to take a step forward.

At this time, Zhai Yunsheng looked at the little girl standing there.

Xie Wanying faced the lead glass, as if she was recalling the surgical scene just now and sorting out.
