Case Reports
Pipeline Embolization Device For Treatment of Craniocervical Internal Carotid Artery Dissections.
Dissecting pseudoaneurysms of the craniocervical circulation are uncommon, accounting for only 3% of all cerebral aneurysms. These aneurysms pose a challenge due to their location and anatomic configuration. The Pipeline Embolization Device (PED) is a flow diversion technique that successfully treats aneurysms by diverting blood flow away from the aneurysm and reconstructing the diseased parent artery by altering its hemodynamics. ⋯ PED placement offers a safe and effective method of treating spontaneous or traumatic craniocervical carotid artery dissections with excellent neurologic outcomes postoperatively and complete long-term aneurysmal occlusion.

Intraosseous petrous apex schwannomas are an exceedingly rare entity; little is known about their epidemiology, natural history, and postoperative outcomes. ⋯ Our 2-year follow-up demonstrates slow growth and success of multimodal management in the treatment of these tumors. We review the 3 prior reports of petrous apex schwannomas and identify unifying radiographic and clinical characteristics to aid future diagnostic considerations of lesions of the petrous apex.

The pedicled temporoparietal fascial flap (TPFF) with a direct superficial temporal (STA) artery to middle cerebral artery (MCA) bypass is a novel combined revascularization approach for moyamoya angiopathy (MMA). With this case series, we aim to report the initial experience with pedicled TPFF combined revascularization for MMA treatment. ⋯ The TPFF combined approach is a viable strategy for revascularization in MMA. This technique may be suboptimal in patients presenting with acute ischemia and/or mRS score >3.

To analyze the preservation of hypothalamic function using the endoscopic endonasal approach (EEA) in a single-center clinical series of patients with hypothalamus-invaded craniopharyngioma (CP) and compare this series with reported cases by the open transcranial approach (TCA). ⋯ EEA can achieve greater gross total resection than TCA when performed by an experienced surgeon. Combined with the reduced postoperative hypothalamic damage in our patients with only hypothalamus-invaded CP, especially the shortened time horizons of hypothalamic obesity development and reduced percentage of patients with obesity, the EEA technique should be a preferred alternative over TCA.

The reported incidence of postoperative ileus (POI) after spine surgery depends on the surgical approach and definition used. It is therefore possible that the overall incidence is substantially higher than previously thought. POI has consequences for both the patient and hospital resources, and can significantly increase health care costs. ⋯ Despite use of early interventions, the median LOS remains significantly longer in patients who develop POI after complex spine surgery. Knowledge of the associated predictive risk factors could potentially assist with the development of rigorous, evidence-based preventative strategies.
