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.
A degenerated artery is definitely not characterized by being as thick as the aorta trunk growing into a tree trunk, but rather by having a long and thin stroke, which makes it easier to be occluded. Does this mean that this degenerated artery is completely unimportant? Otherwise, why has it degraded?
?According to human research, the degraded parts of the human body have their 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 from the posterior choroidal artery that anastomoses, the patient will suffer from hemiplegia, visual blindness and other symptoms.
The consequences of ischemia are terrible, and bleeding is definitely even more terrible.
Is there an aneurysm of the anterior choroidal artery? 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 glanced at it and saw that there was no ischemic part and no bulging, so there should be no big 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 are often small in size. 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 knowledge base of medicine 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 people who wait and see surgery can only think in their hearts: Cao Yong wins numb again.
The microcatheter enters 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 a lathe to send 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. (Remember the website address: www.hlnovel.com
