Application Research Of Acute Phase Microsurgery Through Lateral Supraorbital Approach For Ruptured Anterior Circulation Aneurysms

Objective:To explore the efficacy and safety of the acute phase microsurgery through lateral supraorbital approach for ruptured anterior circulation aneurysms. Methods:The clinical data of patients with ruptured anterior circulation aneurysms(Preoperative Hunt-Hess grade I to III) who undergent acute phase microsurgical treatment through lateral supraorbital approach and pterional approach from March 2014 to December 2015 in Department of neurosurgery,China-japan Union Hospital,Jilin University,Including preoperative Hunt-Hess grade,the age,sex ratio,location of aneurysms,diameter of aneurysms,operative opportunity,rate of intraoperative rupture of the aneurysms,intraoperative blood transfusion,decompressive craniectomy rate,operative time,operative incision lengths,postoperative hospitalization and Glasgow Outcome Scale at 3 months after surgery were collected and analyzed statistically in order to evaluate the clinical effect of the microsurgery through lateral supraorbital approach. Results:Rate of intraoperative rupture of the aneurysms,Intraoperative blood transfusion,decompressive craniectomy rate and Glasgow Outcome Scale at 3 months after surgery showed no significant difference between two groups( P>0.05),but the patients through lateral supraorbital approach had shorter operative time,operative incision lengths and shorter postoperative hospitalization than pterional approach,there was significant statistical significance(P<0.001). Conclusion:Acute phase microsurgical treatment for ruptured anterior circulation aneurysms with preoperative Hunt-Hess grade I to III through lateral supraorbital approach is safe and effective,faster and minimally invasive than pterional approach,it could be as alternative widely applied to acute phase microsurgery of low grade Preoperative Hunt-Hess grade ruptured intracranial anterior circulation aneurysms.
