Introdução: Os aneurismas de bifurcação da artéria carótida interna (ICAbiAs) são pouco comuns. Têm uma incidência muito baixa em adultos, representando apenas 5% de todos os aneurismas intracranianos, e são ainda menos comuns entre os aneurismas da artéria carótida interna (ICA). As séries cirúrgicas relativas exclusivamente ao ICAbiAs são muito escassas. Métodos: Descrevemos 30 pacientes ICAbiAs tratados cirurgicamente de junho de 1995 a janeiro de 2020, num universo de 648 aneurismas operados pelo autor sênior deste artigo. Resultados: 46% (14/30) do ICAbiAs foram rompidos na apresentação. 73% dos 30 pacientes tiveram um bom resultado (escala de Glasgow com escore 5), enquanto oito pacientes (26,6%) morreram. Conclusão: Os aneurismas neste local,de grandes dimensões, com pescoço largo, incorporando a origem das artérias cerebrais médias ou anteriores, e especialmente no que diz respeito ao pulso de martelo d’água com efeito direto no fluxo carotídeo, favorecem frequentemente o tratamento cirúrgico, em detrimento do enrolamento endovascular ou de stent.
Introduction: Internal carotid artery bifurcation aneurysms (ICAbiAs) are uncommon. They have a very low incidence in adults, accounting for only 5% of all intracranial aneurysms, and are even less common amongst aneurysms of the internal carotid artery (ICA). Surgical series regarding exclusively ICAbiAs are very scarce. Methods: We describe 30 ICAbiAs surgically treated patients from June 1995 to January 2020, in a universe of 648 aneurysms operated by the senior author in this paper. Results: At presentation 46% (14/30) of the ICAbiAs were ruptured. Good outcome was found in 73% of the 30 patients (Glasgow Outcome Scale score 5), whereas eight patients (26.6%) died. Conclusion: Aneurysms at this location, large sized, with broad neck, incorporating the origin of the middle cerebral or anterior cerebral arteries, and especially regarding the direct water hammer effect of flow at the carotid summit, often favor surgical treatment, in detriment of endovascular coiling or stenting.
