ABSTRACT

OBJECTIVE:

To describe five cases of giant carotid cavernous aneurysms which evolved with spontaneous thrombosis of internal carotid artery (STICA), with emphasis at epidemiology, clinical presentation, natural history, related factors and neurological outcome.

METHOD:

There were 711 consecutives patients with 802 aneurysms with and without surgical treatment during a period of 19 years. We selected 35 patients with 40 carotid cavernous aneurysms (5 percent) of which 20 (50 percent) were giant aneurysms. Among those cases, 5 patients evolved with STICA (25 percent). Symptoms and findings at presentation were recorded and compared with those at outcome.

RESULTS:

Clinical presentation was commonly related to atherosclerotic factors such as elevated blood pressure (80 percent), diabetes mellitus (40 percent) and dislipidemy (40 percent). All patients presented with hemicranial headache, ophthalmparesy and retro bulbar pain, and after STICA all presented improvement of symptoms. After STICA, 4 patients had regression of deficit, 2 partial and 2 complete. Four patients had sensorial trigeminal neuropathy in V1 and V2 territories, also showing improvement of symptoms after STICA.

CONCLUSION:

STICA is a common outcome in giant carotid cavernous aneurysms, and is related with significant improvement of symptoms; however, it may be catastrophic for those patients without efficient collateral circulation.
RESUMO

OBJETIVO:

Relatar cinco casos de aneurismas gigantes intracavernosos que evoluíram com trombose espontânea da artéria carótida interna (TEACI), estudando-se prevalência, apresentação clínica, história natural, fatores associados e prognóstico neurológico.

MÉTODO:

Análise de 711 pacientes consecutivos com diagnóstico de 802 aneurismas cerebrais submetidos a tratamento clínico ou cirúrgico num período de 19 anos. Foram identificados 40 aneurismas intracavernosos, sendo que 20 desses eram gigantes. Dentre esses, 5 pacientes com aneurismas gigantes intracavernosos que evoluíram com TEACI (25 por cento). Os sintomas e sinais neurológicos da apresentação foram registrados e comparados ao término do acompanhamento.

RESULTADOS:

Todos pacientes apresentavam cefaléia hemicraniana, apresentavam oftalmoplegia e dor retro-orbitária. Freqüentemente estavam associados a fatores ateroscleróticos como HAS (80 por cento), diabetes melito (40 por cento) e dislipidemia (40 por cento) e após a TEACI evoluíram com melhora desses sintomas. Após a TEACI, 4 pacientes tiveram regressão do déficit, sendo que em 2 a regressão do déficit foi total. Quatro pacientes apresentavam hipostesia no território de V1 e V2. Todos apresentaram melhora desse sintoma.

CONCLUSÃO:

A TEACI é uma evolução comum em aneurismas intracavernosos gigantes, e está associada à melhora importante dos sintomas. No entanto pode ser catastrófica naqueles pacientes sem circulação colateral eficiente.
