What are the sequelae of craniotomy for cerebral aneurysm?

The onset of cerebral aneurysm mainly refers to the state of a prominent tumor with localized abnormal expansion of the lumen of the patient's cerebral artery. The occurrence of cerebral aneurysm is one of the most important causes of subarachnoid hemorrhage. The patient suffers from headaches, drowsiness, confusion, neurological dysfunction, and may even lead to a deep coma, threatening the patient's life safety. We usually treat the occurrence of cerebral aneurysms through craniotomy. Although craniotomy can help us treat cerebral aneurysms, its sequelae are also a part that we cannot ignore.

How to detect a brain aneurysm?

1. Routine blood test, erythrocyte sedimentation rate and urine test: Generally, there are no specific changes. In the early stage of aneurysm rupture and bleeding, the white blood cell count often exceeds 10×109/L, and the blood sediment usually increases from mild to moderate, which is consistent with the increase in the number of white blood cells. Proteinuria and glycosuria may appear in the early stage, and tubular urine may appear in severe cases. Proteinuria lasts for a short time and returns to normal after a few days.

2. Lumbar puncture: When the aneurysm has not ruptured, there is no abnormal change in the cerebrospinal fluid examination during lumbar puncture. When the aneurysm ruptures and bleeds, lumbar puncture is direct evidence of subarachnoid hemorrhage after aneurysm rupture.

3. Biochemical examination of cerebrospinal fluid: sugar and chloride are mostly normal, protein is increased, which is caused by the release of a large amount of hemoglobin after red blood cell lysis and the exudative reaction after bleeding, usually 1g/L. Some people believe that every 10,000 red blood cells lysed in the cerebrospinal fluid can increase 150mg/L protein. Generally, the protein increase is the largest 8 to 10 days after bleeding and gradually decreases. Care should be taken to distinguish the bloody cerebrospinal fluid caused by lumbar injury. Generally, the bloody cerebrospinal fluid caused by lumbar injury will not change to red or yellow after centrifugation, and will not have a positive reaction to benzidine.

4. CT examination: Although the presence, size or location of aneurysms is not as good as cerebral angiography, it is safe, fast, painless for the patient, does not affect intracranial pressure, can be used at any time, and can be observed repeatedly.
