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
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.
