CT Cisternography for Evaluation of Trigeminal Neuralgia when MRI is contraindicated: Case Report.
Trigeminal neuralgia (TGN) causes severe unilateral facial pain. The etiology is hypothesized to be segmental demyelination of the trigeminal nerve root via compression by the superior cerebellar artery (SCA). Microvascular decompression (MVD) allows immediate and long-term pain relief. Preoperative evaluation includes magnetic resonance imaging (MRI) and/or magnetic resonance angiography of the brain. Having a pacemaker is a contraindication for MRI. There have been isolated reports of using computed tomography (CT) cisternography scans for radiation planning for TGN. ⋯ MRI is the preferred method of evaluating for TGN because it offers excellent visualization of vasculature in relation to the trigeminal nerve without accompanying radiation exposure. However, for patients who have contraindications to MRI, CT cisternography is shown to also be an effective method for visualizing the trigeminal root entry zone and nearby vasculature in preparation for MVD of the trigeminal nerve.

There is a dearth of literature regarding management and outcomes of patients with a left ventricular assist device (LVAD) for advanced heart failure who develop intracranial hemorrhage (ICH). We conducted a case series from 2 centers highlighting patient outcomes and prognostic factors to help clinicians better understand and care for these high-risk patients. ⋯ Patients being treated with an LVAD who develop ICH have poor outcomes. Predictive factors for same-admission mortality are lower initial Glasgow Coma Scale score, presence of midline shift, and greater ICH volume.

In the past decade, neurosurgery in Uganda experienced increasing surgical volume and a new residency training program. Although research has examined surgical capacity, minimal data exist on the patient population treated by neurosurgery and their eventual outcomes in sub-Saharan Africa. ⋯ The neurosurgical service provided health care to a large proportion of nonoperative patients. Phone surveys captured data on patients in whom nearly one-half would be lost to subsequent health care. Although mortality during initial hospitalization was high, more than 90% of those discharged survived at 1-year follow up, and the vast majority returned to work and school.

To present diagnosis and surgical management of postlaminectomy spondylolisthesis in patients without preoperative instability and a review of relevant literature. ⋯ In patients without overt pre-existing instability, laminectomy for lumbar stenosis can disrupt spinal stability and result in iatrogenic spondylolisthesis. The extent of decompression of the facet joints, number of levels decompressed, and preoperative disc space height can help assess the risk of postoperative spondylolisthesis. Patients who develop recurrent radiculopathy after decompressive lumbar laminectomy should be evaluated for potential iatrogenic spondylolisthesis.

The choice of appropriate antiplatelet therapy before the Pipeline Embolization Device (PED) placement is usually guided by platelet function testing such as light transmission aggregometry (LTA). In this study, we aimed to define the optimal threshold LTA value for clopidogrel responsiveness to predict the risk of postprocedural thromboembolic complications and to help guide appropriate antiplatelet regimen. ⋯ We observed the greatest increase in the rate of thromboembolic complications with LTA values of ≥50%. This can serve as an appropriate cut-off value for determining the clopidogrel response in patients undergoing endovascular treatment with the PED.
