Postoperative neurological outcome in patients with pituitary apoplexy after transsphenoidal surgery.

OBJECTIVE: Pituitary apoplexy can cause severe neuro-ophthalmologic or endocrinologic sequelae, requiring timely treatment. The present study was performed to evaluate postoperative neurologic outcomes and to identify their risk factors in patients who underwent transsphenoidal surgery for pituitary apoplexy. METHODS: Forty-one consecutive patients with pituitary apoplexy who underwent transsphenoidal surgery were reviewed retrospectively. The initial rates of visual acuity (VA) decrease, visual field (VF) defect, and ocular palsy were 34.1%, 46.3%, and 68.3%, respectively. The median maximal diameter and tumoral volume was 2.6 cm (range, 2.0-4.6 cm) and 5.3 cm(3) (range, 2.4-38.8 cm(3)), respectively. Seventeen patients (41.5%) underwent surgery within 7 days. The median follow-up duration was 45 months (range, 12-196 months). RESULTS: At the last follow-up, 62.9% (22/35) of patients had made a full recovery from preoperative neurologic deficits, with partial recovery observed in the remaining patients. The rates of improvement and full recovery from VA decrease were 92.9% and 57.1%, respectively; those from VF defect were 94.7% and 36.8%, respectively; and those from ocular palsy were 100.0% and 96.4%, respectively. On multivariate analysis, initial visual impairment score (>= 20) was the only significant risk factor for postoperative neurologic sequelae (P < 0.001; odds ratio, 40.8). Surgical timing was not associated with postoperative neurological recovery (P < 0.733). CONCLUSIONS: Ocular palsy was fully recovered in 96.4% patients with pituitary apoplexy after transsphenoidal surgery. Initial visual impairment status was found to be more strongly associated with postoperative neurologic recovery than surgical timing.
