Intraventricular hemorrhage and the subsequent development of posthemorrhagic hydrocephalus (PHH) is one of the most serious complication of prematurity, especially in extremely low birth weight infants.1 Neurodevelopmental delay, epilepsy, and severe cognitive impairment represent common sequelae of PHH.2,3 A ventriculoperitoneal shunt insertion in such premature infants is associated with higher rates of skin erosion, infection, and shunt failure.4 One therapeutic option is represented by the use of temporary cerebrospinal fluid diversion procedures (such as external ventricular drainage, subcutaneous reservoir, and ventriculosubgaleal shunt) to gain time avoiding the PHH secondary damages.5,6 An extremely low birth weight (birth weight = 653 g) infant at 24 + 4 gestational age weeks presented with a grade III intraventricular hemorrhage and periventricular hemorrhagic infarction 5 days after birth. Serial transfontanellar ultrasound disclosed a progressive PHH. Progressive symptomatic PHH, pulmonary hemodynamic instability, and suboptimal general prematurity conditions were the main factors that led to plan a percutaneous transfontanellar ultrasound-guided external ventricular drainage at the neonatal intensive care unit. ⋯ This edited, 2-dimensional operative video highlights the key surgical steps of the proposed procedure (Video 1). All relevant patient identifiers have been removed from the video. Nevertheless, the parent's consent was obtained regarding the procedure, video recording, and redistribution for educational purposes.

The color change of topical intranasal fluorescein has been used to confirm the presence of cerebrospinal fluid (CSF) during endoscopic endonasal surgery. We aimed to validate the use of topical intranasal fluorescein for CSF detection. ⋯ Color change alone is not sufficient to determine a difference between CSF, saliva, and saline. Blood, however, is readily identified using this method. Adjunct characteristics, in addition to the color change, are necessary to properly identify an active CSF leak.

Numerous randomized controlled trials have identified risk factors increasing the postoperative recurrence of chronic subdural hematoma (CSDH). Postoperative subdural air is frequently seen on computed tomography imaging. The aim of this study was to test the hypothesis that the presence of significant subdural air postoperatively is related to recurrence of CSDH after burr-hole surgery. ⋯ Although this is a pilot study, it is suggested that significant postoperative subdural air increases recurrence after initial burr-hole surgery for CSDH in adults ≥75 years of age.

Carotid-cavernous fistulas (CCFs) are acquired pathologic shunts between the carotid circulation and the cavernous sinus that result in venous congestion.1 They often present with ocular symptoms, such as chemosis, proptosis, and blurry vision. Cranial nerve deficits and increased intraocular pressure are often seen on the neuro-ophthalmologic examination.2 If left untreated, they can lead to cortical venous reflux and intracranial hemorrhage. A cerebral angiogram is the gold standard to diagnose these lesions. ⋯ We were able to use Onyx for embolization since the superselective injection did not show cortical venous drainage. This is important as obliteration of cortical veins with liquid embolisate could cause venous infarcts. To our knowledge, this is the first video article that illustrates the endovascular embolization of a CCF and highlights the angiographic findings pre- and post-embolization.
