ABSTRACT

Indocyanine green (ICG) video angiography has been used for several medical indications in the last decades. It allows a real time evaluation of vascular structures during the surgery. This study describes the surgical results of a senior vascular neurosurgeon. We retrospectively searched our database for all aneurysm cases treated with the aid of intraoperative ICG from 2009 to 2014. A total of 61 aneurysms in 56 patients were surgically clipped using intraoperative ICG. Clip reposition after ICG happened in 2 patients (3.2%). Generally, highly variable clip adjustment rates of 2%–38% following ICG have been reported since the introduction of this imaging technique. The application of ICG in vascular neurosurgery is still an emerging challenge. It is an adjunctive strategy which facilitates aneurismal evaluation and treatment in experienced hands. Nevertheless, a qualified vascular neurosurgeon is still the most important component of a high quality work.


A angiografia intraoperatória com indocianina verde (ICG) já foi aplicada em diversas situações clínicas por vários anos. O ICG permite avaliação em tempo real de estruturas vasculares durante a cirurgia. Este artigo descreve os resultados cirúrgicos do autor sênior. Avaliamos retrospectivamente os casos de aneurismas intracranianos operados de 2009 a 2014. Um total de 61 aneurismas em 56 pacientes foram operados com ICG. O reposicionamento do clip ocorreu em 2 casos (3.2%). Geralmente, taxas variáveis de reposicionamento do clip têm sido descritas (2%–38%). A aplicação de ICG na neurocirurgia vascular ainda é um desafio crescente. É um artifício que auxilia na avaliação e tratamento de aneurismas intracranianos em mãos experientes. No entanto, um neurocirurgião vascular continua sendo o principal componente de um resultado cirúrgico de alto nível.

ABSTRACT

Dobras de coroide é considerado o achado fundoscópico mais prevalente nos casos de tumor orbitário. São ondulações no epitélio pigmentado da retina, membrana de Bruch, porção interna da coriocapilar e que, em alguns casos, podem acometer a retina neurossensorial, sendo então chamadas de dobras coriorretinianas. Diversas condições, oculares e sistêmicas, cursam com dobras de coroide e devem ser corretamente investigadas e, caso necessário, prontamente tratadas. Nesta revisão iremos abordar os aspectos gerais das dobras de coroide, enfatizando suas características nos seguintes exames de imagem: Retinografia, autofluorescência, angiofluoresceínografia e tomografia de coerência óptica.


Choroidal folds is considered the most prevalent funduscopic finding in cases of orbital tumors. They are ripples in the retinal pigment epithelium, Bruch's membrane, the inner portion of the choriocapillaris and in some cases, may affect the neurosensory retina, and then called chorioretinal folds. Several ocular and systemic conditions are associated with the finding and must be properly investigated and, if necessary, promptly treated. In this review we discuss the general aspects of choroidal folds, emphasizing their characteristic features in the following ophthalmological imaging tests: Retinography, fundus autofluorescence, fluorescein angiography and optical coherence tomography.
