Aneurismas paraclinoideos: experiencia personal de 1 año en el Hospital Regional de Temuco

Abstract

A personal experience is presented in treating 5 patients with 7 paraclinoid aneurysm who underwent surgery at Hospital Regional Temuco between june 2015 and july 2016 (13 months). All patients were previously discussed with local interventional neuroradiologist considering them not favorable to endovascular therapy. Mini pterional craniotomy with extradural clinoidectomy and internal cervical carotid artery exposure was performed in all of them. 4 patients presented with subarachnoid hemorrhage and required urgent brain surgery. Direct clipping was optimal in 6 aneurysm and 1 was treated with trapping. 4 patients had no neurological deteriotation with excellent outcome and 1 patient died because of hypoperfusion secondary to the supraclinoid carotid trapping. Interdisciplinary management, preoperative planning and neuroanatomy knowledge are emphasized in order to treat this pathology.
