Endoscopic Intraventricular Atrial Adhesiolysis for the Treatment of Entrapped Temporal Horn after İntraventricular Tumor Surgery

A 21-year-old male patient was operated for third ventricle tumor (central neurocytoma) and showed improvement in the early postoperative period. After 2 weeks of surgery, the patient neurologic status deteriorated with acute decreased level of consciousness. Neuroimaging of the brain revealed entrapped left temporo-occipital horns with adhesion bands at the level of the atrium. Patient was operated with neuronavigation-guided endoscopic approach to the left atrium through the left posterior parietal region. Band adhesiolysis was performed with no complications. The patient showed fast improvement, and follow-up brain magnetic resonance imaging after 2 years showed the release of the ventricular entrapment with significant regression of the left ventricle size.
