The purpose of our paper is to present a case of a rare complication of posterior lumbar surgery. Our patient presented for elective lumbar decompression, which was complicated by durotomy. She then developed sudden headache and right eye pain once upright on postoperative day 2. ⋯ The diagnosis is complicated by a durotomy, which led to cascade in the differential diagnosis to rule out intracranial pathology. Her age and home medications, which had sympathomimetic effects, placed her at increased risk, but lying prone in the dark under the drapes was likely the lead causative factor. In conclusion, a postoperative posterior spine patient with eye pain and changes in vision and pupils should be evaluated with AACG in mind due to the devastating consequences if left untreated or treatment is delayed.

Lack of risk stratification among patients with varying severities of compound head injury has resulted in too-inconsistent and conflicting results to support any management strategy over another. The purpose of this study was to validate a new clinico-radiological grading scheme with implications on outcome and the need for surgical debridement. ⋯ The new grading scheme appears to be of practical clinical significance. It shows significant statistical associations with the rates of infection, unfavorable neurologic outcome, delayed seizures, mortality, and duration of hospital stay. The incremental impact of each successive grade on infective complications and unfavorable GOS was independent of GCS and other prognostic factors. Conservative management had significantly lower infection compared to surgical debridement, at least in patients with Grades 1 and 2.

Complicated hydrocephalus, such as trapped fourth ventricle, is challenging. Aqueduct stent placement is a possible alternative to the conventional multiple shunts approach. This article discusses the indications, techniques, and clinical experiences of aqueduct stent placement. ⋯ Aqueduct stent placement is technically feasible and can be useful in selected patients either with endoscopy or open surgery.

Surgical resection of sacral chordomas offers the best long-term prognosis but has high rates of local recurrence, metastases, and mortality. Most prognostic studies are limited by low patient numbers, variation in treatment, follow-up, and prognostic variables studied. The objective of this study was to identify factors associated with recurrence, metastasis, and survival. ⋯ Patients with inadequate resection margins, tumors >8 cm, sacroiliac joint and/or musculature infiltration, and dedifferentiated disease have significantly worse oncologic outcomes. Involvement of gluteus maximus alone confers a higher risk of metastases and local recurrence than involvement of piriformis and gluteus maximus, or piriformis alone.

The aim of this study was to identify whether computed tomography-based morphologic parameters actually are correlated with the rupture status of anterior communicating artery aneurysms (ACoAAs). ⋯ The anterior direction, parent-daughter angle, and size ratio between ruptured and unruptured ACoAAs were found to be statistically significant; they may be implicated in the rupture of ACoAAs, but the size ratio was the strongest factor that was correlated with rupture of ACoAAs based on binary logistic regression.
