Endoscopic colloid cyst resection: technical note.
2011
INTRODUCTION: Since the first reported endoscopic treatment of colloid cysts of the third ventricle by Powel et al. in 1983, several endoscopic techniques have been described. Therefore, the authors describe their technique of neuroendoscopic colloid cyst removal, developed during the last 16 years. TECHNIQUE: With the aid of the specially designed, no-through perforator, the colloid cyst is first partially evacuated to facilitate further dissection and mobilization. By intermittent gentle traction to mobilize the cyst out of the foramen of Monro, detachment from the tela choroidea is finally obtained, making total removal possible. CONCLUSIONS: With the described endoscopic technique, complete removal of colloid cysts is possible in almost 90 % of cases.
