The anterior choroidal artery is a relatively magical artery in neurosurgery.
First of all, in human embryos, all cerebral blood vessels 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.
Interestingly, such an artery that seems to be very important has chosen to degenerate as humans continue to grow. For this reason, its starting point has changed to the middle cerebral artery and posterior communicating artery for some people, but for most people it still starts from the middle cerebral artery and posterior communicating artery. Start 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 its course is long and thin, and it is more likely to be occluded. Does this mean that this degenerated artery is completely unimportant? Otherwise, why has it degraded?
According to human research, every degraded 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, the optic tract, and the internal capsule of the midbrain hippocampus 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 hemiparesis and blindness.
The consequences of ischemia are terrible, and bleeding is definitely even more terrible.
Anterior choroidal artery aneurysm? Long ones can account for several percent of aneurysm cases, so they cannot be said to be rare.
During the first full cerebral vascular examination, the doctor detected the anterior choroidal artery. However, it is not an arterial trunk, it is very small. The blood vessels shown in the DSA image are 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.
Aneurysms of the anterior choroidal artery tend to be small. Even so, as long as the aneurysm in this area becomes slightly larger and is as large as a reservoir aneurysm, the fluctuations of the anterior choroidal artery with a small diameter and small capacity to accommodate water flow can be easily controlled.
It is true that two-dimensional images can easily deceive people in the early stages of disease. The cerebrovascular map happens to be characterized by abundant bifurcations. If the blood vessels are carefully examined, it can be said that they are densely packed and intertwined, just like a pile of tangles.
If doctors rely on the existing medical knowledge base to make calculations, it is faster and more accurate than relying on hand feeling. The hand reflex is purely natural and requires no brain work or calculation.
All those who were waiting to watch the operation could only think in their hearts: Cao Yong has won again.
The microcatheter reaches a certain point and a spring coil is placed for total embolization. Later, I checked the ophthalmic artery again, and the opportunity appeared...
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 surgical scenes just now.
Her brain can't keep up with Brother Cao's touch, but she can review and summarize the surgical experience. This is a very good learning opportunity.
