GONZALEZ-DARDER, J.M.; GONZALEZ-LOPEZ, P.  and  BOTELLA-MACIA, L.. Microsurgical treatment of internal carotid bifurcation aneurysms. Neurocirugía [online]. 2010, vol.21, n.3, pp.205-210. ISSN 1130-1473.

Clinical and imaging findings of a series of 14 internal carotid artery bifurcation aneurysms microsurgically treated are presented. A total of 10 lesions were diagnosed before rupture and 4 patients presented with subarachnoidal hemorraghe and frontobasal intracerebral bleeding. Diagnosis was done using neuroimaging (CT scan, angio-CT-3D, angio-MRI, angiography) but patients with ruptured aneurysms were treated with the sole information provided by the angio-CT-3D. The average fundus size was 8.4mm (3-13.3) and the average neck size was 6.8mm (3-9.6), being the fundus-to-neck ratio 1.32 (0.46-2.05). All lesions were microsurgically treated through a pterional approach with the help of temporary clipping of the aferent vessesl in all cases. We used peroperative neuroprotective, neuromonitorization and micro-doppler cerebral flow measurement. Clinical results were excellent with 13 patients GOS grade 5 and one grade 4 three month afterwards of hospital discharge and complete exclusion of the lesion in angiographic controls done solely in patients with ruptured lesions.
