Surgical clipping is still a good choice for the treatment of paraclinoid aneurysms / A clipagem cirúrgica é uma boa opção para o tratamento de aneurismas paraclinóideos

ABSTRACT

ABSTRACT Paraclinoid aneurysms are lesions located adjacent to the clinoid and ophthalmic segments of the internal carotid artery. In recent years, flow diverter stents have been introduced as a better endovascular technique for treatment of these aneurysms. Method From 2009 to 2014, a total of 43 paraclinoid aneurysms in 43 patients were surgically clipped. We retrospectively reviewed the records of these patients to analyze clinical outcomes. Results Twenty-six aneurysms (60.5%) were ophthalmic artery aneurysms, while 17 were superior hypophyseal artery aneurysms (39.5%). The extradural approach to the clinoid process was used to clip these aneurysms. One hundred percent of aneurysms were clipped (complete exclusion in 100% on follow-up angiography). The length of follow-up ranged from 1 to 60 months (mean, 29.82 months). Conclusion Surgical clipping continues to be a good option for the treatment of paraclinoid aneurysms.

RESUMO

RESUMO Aneurismas paraclinóideos são lesões localizadas adjacentes aos segmentos clinóideos e oftálmicos da artéria carótia interna. Os stents desviadores de fluxo tem sido crescentemente aplicados com sucesso. Métodos De 2009 a 2014, um total de 43 aneurismas paraclinóideos foram clipados em 43 pacientes. Analisamos retrospectivamente os dados dos pacientes e desfechos clínicos. Resultados Vinte seis aneurismas (60,5%) foram de artéria oftálmica e 17 de artéria hipofisária superior (39,5%). O acesso extradural à clinóide foi utilizado para todos aneurismas. Cem por cento dos aneurismas foram clipados com oclusão de 100% na angiografia controle. O tempo de follow-up oscilou de 1 a 60 meses, com media de 29 meses. Conclusão A clipagem cirúrgica é uma opção boa e segura para o tratamento de aneurismas paraclinóideos.
