The anterior choroidal artery is a relatively magical artery in neurosurgery.
First of all, in human embryos, all cerebral blood vessels initially originate from the internal carotid artery. The internal carotid artery sends out two vascular trunks other than the ophthalmic artery, one of which is the anterior choroidal artery.
What's interesting is that such an artery, which seems to be very important, has chosen to degenerate as humans continue to grow. For this reason, some people have changed its starting point from the middle cerebral artery and the posterior communicating artery, while most people still have it.
Starting from the lateral wall of the internal carotid artery.
The characteristic of a degenerated artery is definitely not that it is as thick as the aorta trunk grows into a tree trunk, but that it has a long and thin stroke, which is more likely to cause occlusion. Is this degenerated artery completely unimportant? Otherwise, why is it degenerated?
Where is it?
According to human research, every degenerated part of the human body has its own special significance. No part of the human body can be said to be completely useless. The same is true for the anterior choroidal artery. It supplies blood to the basal ganglia and the optic tract to the internal capsule of the hippocampus in the midbrain.
and other important brain tissue areas.
If it is ischemic and does not provide support to the posterior choroidal artery that anastomoses, the patient will suffer from symptoms such as hemiplegia and blindness.
The consequences of ischemia are terrible, and bleeding is definitely even more terrible.
Are there long aneurysms of the anterior choroidal artery? If they are long, their number can account for a few percent of the cases of aneurysms. It cannot be said to be rare.
During the first full cerebral vascular examination, the doctor saw the anterior choroidal artery. However, it was not an arterial trunk and was very small. The blood vessels shown in the DSA image were light black, unclear and not eye-catching.
The doctor took a quick look and saw that there was no ischemic part and there was no bulging, so there should be no major problem.
But now the microcatheter in the surgeon's hand can smoothly and quickly enter the anterior choroidal artery, indicating that the diameter of this artery has become larger?
The anterior choroidal artery should have a small diameter according to common sense. An increase in its diameter may indicate a problem, that it is about to become an aneurysm.
The size of the aneurysm of the anterior choroidal artery is often very small. Even so, as long as the aneurysm in this place becomes slightly larger and is as large as the aneurysm of the reservoir, the lower anterior choroidal artery, which is small in diameter and can accommodate small water flow, can be easily controlled.
fluctuation.
It is true that two-dimensional images can easily deceive people in the early stage of disease. Cerebral blood vessel images happen to be rich in bifurcations. If the blood vessels are carefully studied, they can be said to be densely packed and intertwined, like a tangled pile.
If doctors rely on the existing medical knowledge base to make calculations, it is faster and more accurate than relying on hand feel. The hand reflex is purely natural and requires no brainpower or calculation.
All those who were waiting to watch the operation could only think in their hearts: Cao Yong has won again.
The microcatheter enters a certain point and a spring coil is placed for total embolization. Then the ophthalmic artery is checked again, and the opportunity arises...
Half an hour later, the operation was over.
The nurse uses the lathe to take the patient back to the ward.
"Director Zhai." Deputy Director Lu said, accompanying Zhai Yunsheng, a great expert, to take the first step.
At this time, Zhai Yunsheng glanced at the little girl standing there.
Facing the lead glass, Xie Wanying seemed to be recalling and sorting out the previous surgery scenes over and over again.
Her brain cannot keep up with Brother Cao's touch, but she can review and summarize the surgical experience. This is a very good learning opportunity.
