Questions about Interventional Therapy of Cerebrovascular Disease


Questions about Interventional Therapy of Cerebrovascular Disease. Cerebrovascular diseases are a group of diseases that occur in the blood vessels of the brain and cause damage to the brain tissue due to disorders of blood circulation in the brain.



1. What is cerebrovascular disease?

Cerebrovascular diseases are a group of diseases that occur in the blood vessels of the brain and cause damage to the brain tissue due to disorders of blood circulation in the brain.

The “cerebrovascular accidents”, “strokes” and “strokes” we talk about in our lives are all cerebrovascular diseases.

Clinically, acute onset is the majority, mostly middle-aged and elderly patients, with hemiplegia and speech disorder. Acute cerebrovascular diseases are generally divided into two types: ischemic and hemorrhagic.

At present, cerebrovascular disease has become one of the main causes of death in our country, and it is the first cause of disability.

The sequelae caused by it have brought a huge burden to the patients themselves, their families and society.



2. What is cerebrovascular interventional therapy? Cerebrovascular interventional therapy is a type of minimally invasive surgery.

The doctor makes a 2-3mm incision in the patient’s skin, and then passes through the blood vessels in these places, usually selecting the femoral artery, inserting surgical instruments, and then under the guidance of the X-ray equipment, conveying the guide wire or catheter, bypassing other The blood vessels directly reach the problematic blood vessels in the brain, and the blood vessels are processed, such as balloon dilation and stent placement.



3. When is cerebrovascular intervention required?

The indications for cerebrovascular intervention include:

1) Intracranial and extracranial vascular disease. Such as hemorrhagic or occlusive cerebrovascular disease.

2) Etiological examination of spontaneous intracerebral hematoma or subarachnoid hemorrhage.

3) Understand the blood supply of head and face tumors before surgery.

4) Observe the relationship between the blood supply of intracranial space-occupying lesions and adjacent blood vessels and the qualitativeness of certain tumors.



4. What are the methods of cerebrovascular interventional therapy?

There are many methods for interventional treatment of cerebrovascular diseases, which are mainly divided into ischemic and hemorrhagic diseases according to different lesions.


Generally speaking, the interventional treatment methods for ischemic cerebrovascular disease include balloon dilatation, mechanical thrombus removal therapy, thrombolytic intervention for acute large vessel occlusion, or stent therapy.


The interventional treatments for hemorrhagic cerebrovascular disease include balloon embolization, embolization of aneurysms, and stent-assisted coil embolization.


Questions about Interventional Therapy of Cerebrovascular Disease



5. Is cerebrovascular interventional therapy safe?

Any treatment has certain risks. The more common complications of cerebrovascular intervention include bleeding at the puncture site and allergy to contrast agents.

The more serious cases include secondary blood. However, the incidence of complications is very low. According to statistics, it is about 0.1~0.3%. At present, the technology is very mature.

Compared with craniotomy, the risk is greatly reduced, and the success rate is also high. Therefore, it is relatively safe, but it is impossible to guarantee foolproof.


6. Will cerebrovascular intervention affect life span?

Cerebrovascular interventional therapy is a commonly used surgical method for the treatment of cerebrovascular diseases.

As long as the indications are strictly grasped, the treatment itself does not affect the life of the patient, and the patient does not need to worry too much.

There are individual differences in the postoperative life span of patients, which are related to various factors such as the type, location and comorbidities of cerebrovascular disease.

Therefore, patients need to take drugs regularly after surgery and review them regularly to achieve the goal of prolonging survival.


7. Will it recur after cerebrovascular intervention?

Cerebrovascular disease may recur even after interventional surgery. For example, if a patient has had cerebrovascular stenosis before, even if the stent is put in, there is still the possibility of restenosis after the operation. Patients who have had a cerebral infarction may also have it again. Especially patients with high-risk factors such as hypertension and hyperlipidemia, there is a certain risk of recurrence. Therefore, patients should follow the doctor’s instructions for life intervention and medication to reduce the risk of recurrence.


8. Is a stent necessary for cerebrovascular stenosis?

Not all cerebrovascular stenosis is treated with stents. The doctor will consider the patient’s symptoms and the degree of cerebrovascular stenosis. Generally speaking, stent treatment is necessary for stenosis above 70%. If it is not so severe, medication or other interventional treatments can be used to help patients improve the stenosis.


9. Can a stent be placed after a cerebral infarction has occurred?

Patients with cerebral infarction can be treated with stents, but there is no therapeutic significance for the cerebral infarction that has occurred, and there is no much improvement in symptoms. In particular, patients with cerebral infarction may cause plaques to fall off if the stent is placed. After the stent is placed, the patient needs to take anticoagulant drugs for life, which increases the risk of cerebral hemorrhage. Therefore, patients with cerebral infarction rarely receive stent treatment. Yes, conservative treatment is the mainstay. Usually, only patients with cerebral infarction caused by high cerebrovascular stenosis need to place a stent.


10. How to prevent cerebrovascular disease?

Pay attention to a healthy diet in daily life, avoid high-oil and high-salt foods, and maintain a proper weight. Perform moderate physical activity and avoid excessive exercise. Usually avoid sitting for a long time, avoid overwork and exert too much force. The elderly should prevent rapid changes in body position and improve constipation. Regular health checkups are usually required to prevent and treat problems early.
