Is surgery for blocked cerebral blood vessels dangerous?

The risk level of surgery for blocked cerebral blood vessels varies depending on individual differences and must be assessed based on the patient's specific condition. Cerebrovascular occlusion surgeries can be categorized as high-risk or low-risk according to their potential surgical risks. The detailed analysis is as follows:

High-risk situations mainly include older patients with reduced physical function and lower immunity, which naturally increase surgical risks. Additionally, if patients have underlying medical conditions such as hypertension, diabetes, or heart disease, these may lead to complications like blood pressure fluctuations or cardiac events during surgery, thereby increasing the overall surgical risk.

Lower-risk situations generally involve younger patients with better physical health and relatively minor surgical risks. Moreover, these patients typically do not suffer from significant comorbidities, or their conditions are mild—such as transient ischemic attacks caused by cerebrovascular blockage—in which case the surgical risk is relatively low. If surgery is required for cerebrovascular occlusion, it must be performed under the guidance of a qualified physician, with comprehensive preoperative evaluation and preparation to minimize surgical risks. For high-risk patients, less invasive approaches such as endovascular interventions may be considered, or conservative management with regular follow-up monitoring may be adopted to achieve therapeutic goals.
