Objective: Colloid cysts are cystic or solid lesions at the anterior part of the third ventricle close to the foramen of Monro. Due to this location surgical treatment bears the risk of venous bleedings and/or fornix lesions. Endoscopic treatment strategies and complication management are presented by the authors.

Methods: This study retrospectively analyses data of 19 cases with colloid cysts. Off-line video analysis of the neuroendoscopic procedures, MRI analysis and clinical follow-up were performed.

Results: Twenty patients (11 male, 9 female) underwent endoscopic cyst fenestration or resection in our department between 2011 and 2016. In three cases of cyst fenestration a second procedure was necessary. Heavy venous hemorrhages occurred in four cases. The hemorrhages were either stopped by constant irrigation or by dry-field technique. Distorted surface or loss of ependymal integrity at the foramen of Monro was observed in five cases (20%). Only in one case those findings were related to postoperative memory disturbances. Shunt independency was achieved in all cases.

Conclusion: The surgical treatment of colloid cysts is recommended due to the potential life-threatening course. However, surgeons have to be aware of the potential intraoperative risk of hemorrhages due to the anatomic location. Different options of bleeding management are feasible. Intraoperative lesions at the foramen are common, but obviously clinical correlation is rare.
