1.What is cerebral aneurysm clamping?
It is a surgical method to deal with aneurysm directly under microscopic craniotomy, i.e. craniotomy. A special aneurysm clamp is used to close the neck of the aneurysm and protect the patency of the aneurysm-carrying artery.
2.Which patients need to have cerebral aneurysm clamping?
①Patients with combined intracerebral hematoma occupancy that requires craniotomy.
②Patients with severe arterial tortuosity and sclerosis, which make it difficult to get the interventional catheter in place.
3.What is the timing of cerebral aneurysm clamping surgery? Wu
①Early surgical treatment (within 72 hours): Patients whose condition has improved after external drainage of cerebrospinal fluid in H-H: grade III-IV can be treated with aneurysm clamping surgery.
②Late surgical treatment (after two weeks): Patients with onset for more than 72 hours at the time of admission can be treated with aneurysm clamping after the end of the vasospasm period.
③If intracranial hematoma and brain herniation are combined, then emergency surgery will be performed to remove the hematoma and clip the cerebral aneurysm at the same time.
4.What is the result of cerebral aneurysm clamping surgery?
The main causes of cerebral aneurysm rupture that lead to severe disability and mortality are secondary hemorrhage, acute hydrocephalus and cerebrovascular contracture. As a result of cerebral aneurysm clamping, the risk of rebleeding is relieved and the safety of the treatment of hydrocephalus and cerebrovascular spasm is ensured in the later stage. According to statistical studies, cerebral aneurysm clamping greatly reduces the disability and mortality rate.
5.What is cerebral arteriovenous malformation resection?
It is a surgical method to remove the cerebral arteriovenous malformation directly under the microscope. The artery supplying the malformed blood vessel is cut off, the malformed blood vessel mass is peeled off, and the draining vein is finally cut off.
6.What patients need arteriovenous malformation surgery?
①Patients with frequent seizures and poor results of drug treatment.
②Patients who have symptoms of progressive neurological localization damage or mental retardation (blood-stealing syndrome).
③Those with combined intracranial hematoma or intracranial hypertension.
④Small and medium-sized AVMs located in non-functional areas of the hemisphere.
⑤ Large AVMs where the natural risk is greater than the risk of surgical resection or where preoperative embolization has been successfully performed.
7.Which patients cannot be treated by surgical resection of arteriovenous malformations?
①Deep brain, internal capsule, basal ganglia and brainstem arteriovenous malformations.
②Extensive or huge cerebral arteriovenous malformation.
③Incidentally discovered, asymptomatic person.
④Older people over 70 years old with serious diseases of heart, kidney and respiratory system.
