Objective:
To evaluate the application of eyebrow-lateral keyhole approach in clipping of anterior communicating artery aneurysm (ACAA) through observing the therapeutic effect of eyebrow-lateral keyhole approach on ACAA.
Methods:
In 37 patients with ACAA, cisterns were exposed via the eyebrow-lateral keyhole approach to reveal ACAA complex followed by clipping of ACAA. Of the 37 patients, external ventricular drainage was performed on 5 patients before microsurgery. All patients underwent head CT angiography on the second day after operation.
Results:
Clipping of ACAA was successful in all patients at the first time. In 3 patients, ruptured aneurysm occurred during operation. Three patients underwent ventriculoperitoneal shunt because of postoperative hydrocephalus. Two patients had one-sided anterior cerebral artery infarction after operation. No patient died during operation. Follow-up after the operation indicated that 26 patients returned to normal life and work, 6 patients were able to look after themselves, 4 patients required care in their daily life and one patient died.
Conclusion:
The eyebrow-lateral keyhole approach is a preferred choice for surgical treatment of ACAA because it can cope with brain swelling and intraoperative ruptured aneurysm. However, it has a certain range of application, so we must strictly follow its indications.
