Remote cerebellar hemorrhage (RCH) after intracranial surgery is a rare complication. Cerebellar hemorrhage is the most commonly described remote site hemorrhage after surgery for supratentorial pathologies. Although this is a rare complication 0.04% to 0.8%, it can be devastating in terms of patient outcome. There are various hypotheses to explain the occurrence of RCH. We report 6 cases of RCH after surgery for supratentorial lesions, discuss the pathophysiology, and review the pertinent literature. ⋯ RCH is a rare complication but can lead to catastrophic results. Loss of large volumes of cerebrospinal fluid or sudden alteration in intracranial pressure due to removal of a mass lesion is the likely etiology. Although majority of cases may be managed conservatively, in a subset of cases with neurologic deterioration, surgery may be required as a life-saving procedure.

We present the case of a 57-year-old female with hypertension, current smoker status, and recent headaches. Imaging studies showed an unruptured 8-mm basilar apex wide neck aneurysm located 4 mm above posterior clinoid (Figure 1) with a 3-mm anterior communicant artery aneurysm. No contraindications were encountered for endovascular treatment, although after we evaluated endovascular and surgical options, surgical clipping was considered also a safe and favorable option based on anterior projection of aneurysm, height of the basilar artery bifurcation, small and elongated posterior communicant artery, and available space between posterior clinoid and basilar artery (4 mm). ⋯ Micro-Doppler and intraoperative angiogram confirmed aneurysm exclusion and patent parent vessels (Video 1). The patient developed minimal ptosis due to partial right oculomotor nerve palsy that recovered completely in 2 weeks; otherwise, her neurologic exam was normal. At 1-year follow up, computed tomography angiography showed complete aneurysm exclusion.

In Cambodia, the most common victims of traumatic brain injury (TBI) are men 20-30 years of age involved in motor vehicle collision. Secondary injury sustained by these patients occurs during the time period between initial insult and hospital admission. Strengthening prehospital systems for TBI in low- and middle-income countries (LMICs) such as Cambodia is therefore a key element of the development agenda for universal health equity. We report a retrospective analysis of the relationship between prehospital delays and TBI outcomes among patients from a large government hospital in Cambodia. ⋯ In a retrospective cohort of >2000 patients with TBI from Cambodia, we found that increasing IAD was associated with worsening outcome, especially beyond the 4-hour threshold. These data should inform development of prehospital guidelines for TBI care in LMICs.

Video 1 describes the technique of microsurgery removal of acoustic neuromas (ANs) using new technologies. The Flexible 2μ-Thulium hand-held laser fiber (Revolix jr, LISA laser products, 7 OHG, Berlin, Germany) and Sonopet Ultrasound Aspirator (Stryker, Kalamazoo, Michigan, USA) can be used for a safe and facilitated opening of the internal auditory canal (IAC). We illustrate the operative technique used on a surgical series of 111 cases operated on during the past 8 years, from July 2010 to July 2018. ⋯ In 111 cases the "Sonopet" Ultrasound Aspirator was used to open the IAC and a 2μ-Thulium laser fiber was used for cutting the dura mater of the posterior aspect of petrous bone and the IAC, and it was also used to perform tumor capsule incision. From December 2017 we started to check the removal of tumor inside the IAC with a flexible endoscope 4 mm × 65 cm, (Karl Storz GmbH, Tuttlingen, Germany) in order to detect possible tumoral residue and achieve a radical tumor resection in the fundus. The use of these new technologies seems to be safe and subjectively facilitates the opening of the IAC in AN microsurgery.

To evaluate the health-related quality of life (HRQoL) in patients with carotid stenosis and identify the predictive factors that affect the mental health status in patients after carotid endarterectomy (CEA). ⋯ Contralateral stenosis, dizziness improvement, and hoarseness may be the predictive factors that affect the mental health status in patients after CEA.
