Cerebrospinal fluid fistula after endoscopic skull base surgery

Major vascular structures are always at risk during complex skull base surgery, particularly with use of the endoscopic endonasal approach, and intraoperative damage of the internal carotid artery (ICA) can be a devastating complication.

Arraez et al. from the Department of Neurosurgery, Malaga University Hospital report a case of a young patient who had a major injury of the left ICA during endoscopic resection of a recurrent petrous bone chordoma. Massive bleeding was controlled by a Foley balloon inserted and kept in the resection area. Urgent angiography revealed a persistent leak from the petrous segment of the left ICA, and the vessel was sacrificed with coiling, since a balloon occlusion test showed good collateral blood flow. The patient woke up from anesthesia without a neurological deficit. Salvage resection of recurrent skull base neoplasms deserves specific attention because of the possibility of major vascular damage. In cases of intraoperative ICA injury, its management requires immediate decisions, and the available possibilities for endovascular therapy should always be considered 2).
