摘要

In this article, the authors assessed the use of intraoperative near-infrared indocyanine green videoangiography (ICG-VA) in the micro-surgical resection of nine cases of hemangioblastoma. Although this information is not completely new, the study provides some insights in the use of ICG-VA in the treatment of hemangioblastomas presenting different surgical challenges. According to the authors' experience, ICG-VA provided a valid contribution in most situations. This and other studies suggest that this technique has the potential to become the routine intraoperative vascular imaging during both cerebrovascular and tumour surgery. Nonetheless, it is worth mentioning the fact that the angiographic perspective provided by the ICG video technique is restricted to the field of view through the microscope. Furthermore, blood clots or, according to the authors' experience, scar tissue may hide relevant vascular structures. So, as the ICG fluorescence may be affected by calcifications and thick-walled atherosclerotic vessels, therefore its use in combination with other methods-including visual inspection, intraoperative angiography and Doppler ultrasonography-should be evaluated in difficult cases.
