What are the causes of intracranial hemorrhage after surgery for trigeminal neuralgia?
Disease description:
A friend was hospitalized due to illness and mentioned it was caused by intracranial hemorrhage after surgery for trigeminal neuralgia. Therefore, I would like to ask: what are the causes of intracranial hemorrhage following surgery for trigeminal neuralgia?
Doctor's answer (1)
Dr. Lv Zhiqin
The main causes of intracranial hemorrhage after trigeminal neuralgia surgery include the following:
1. Improper surgical technique: During the surgical procedure, mistakes made by the surgeon or improper use of surgical instruments may damage intracranial blood vessels, leading to vessel rupture and bleeding.
2. Vascular injury: Intracranial arterial vessels may be accidentally injured during surgery, particularly in the area of the gasserian ganglion adjacent to the cavernous sinus and internal carotid artery. Vessel injury and subsequent bleeding may occur if the puncture is performed improperly or if the needle enters too deeply into the foramen ovale.
3. Coagulation dysfunction: The patient may have pre-existing coagulation abnormalities, or coagulation function may not have been adequately assessed and corrected before surgery, leading to uncontrolled postoperative bleeding.
4. Patient's underlying conditions: Chronic diseases such as hypertension, if poorly controlled, may also induce intracranial hemorrhage after surgery.
5. Infection: Although relatively uncommon, infection at the surgical site or other types of infection may lead to vasculitis, which can subsequently cause vessel rupture and bleeding.
In addition, patients should also pay attention to observation and postoperative care, and seek timely medical attention if any abnormalities occur.
