Aneurisma paraclinóideo: técnica cirúrgica e resultados em 51 pacientes Paraclinoid aneurysms: surgical technique and results in 51 patients
Analisam-se 51 pacientes portadores de 55 aneurismas paraclinóideos (APC) submetidos a tratamento cirúrgico. Em decorrência de tratar-se de procedimento de alta complexidade, descrevemos em pormenor os seus aspectos técnicos. O processo clinóideo anterior foi removido por via extradural após secção da duplicação dural da tenda da fissura orbitária superior e/ou por via intradural. Conseguiu-se exclusão do APC nos 51 pacientes. Em dois casos a clipagem foi parcial e, em três, ocorreu oclusão da ACI. Em 42 (82%) pacientes ocorreu bom resultado; em 5 (10%), incapacidade moderada; em 1 (2%), incapacidade grave e três (6%) faleceram por infarto cerebral. Sete (13,7%) pacientes tiveram lesão adicional do nervo óptico, sendo parcial em 4 (7,7%) e total em 3 (6%).<br>An analysis of the surgical results of 51 patients harboring 55 paraclinoid aneurysms is performed, along with a throughoutful description of it’s complex microsurgical technique. The anterior clinoid process was removed by the extradural route after sectioning the dural duplication between the superior orbital fissure and the dura of the temporal lobe, and/or by the intradural approach. All 55 aneurysms was excluded. In two cases the clipping was partial and the internal carotid artery were ocluded in three cases. The surgical outcome was good in 42 (82%) patients, moderate incapacity occurred in five (10%) and severe incapacity in one patient (2%). Three patients (6%) died due to brain infarction. Seven patients (13,7%) had adicional lesion of the optic nerve, being partial in 4 (7,7%) and total in 3 (6%)
