The supraorbital keyhole approach for clipping of anterior circulation ruptured aneurysms

Abstract

<jats:p>Introduction. The supraorbital approach has been demonstrated to be useful, particularly in minimization of brain retraction and exposure to air, decreases blood loss, surgical trauma, operative time and infection rates. While its shortcomings include difficult control of frontal air sinus, narrower surgical view and limited exposure of sylvian fissure.&#x0D; Patients and methods. We retrospectively reviewed the files of patients who underwent clipping of anterior circulation aneurysms through the supraorbital keyhole approach at Neurosurgery Department, Mansoura University between Jan 2014 and May 2016.&#x0D; Results. Twenty-five consecutive patients harbouring aneurysm at anterior circulation underwent clipping through the supraorbital keyhole approach, sixteen A-com artery aneurysms and nine cases of ICA aneurysms Table 1 show the location of aneurysms. Eleven patients were males, and 14 were females. The ages ranged from 44 to 69 with a mean age of 61.9 years. All patients were presented with subarachnoid haemorrhage due to rupture of aneurysms in anterior circulation The Hunt and Hess grade was (1.50 ± 0.65) and Fisher grade was (1.67 ± 0.45). The average operative time was 3.32 ± 1.14 hours. Follow-up ranged from 1 to 16 months with a mean of 7 months&#x0D; Conclusion. Surgical clipping of some selected aneurysms of anterior circulation can be operated through minimally invasive supraorbital approach which minimize the dissection and retraction of the brain, reduce operative time and blood loss with small incision and good cosmetic results.</jats:p>
