High-dose ASA therapy and clopidogrel treatment for at least 6 months were associated with a reduced incidence of ischemic events, without affecting the risk of hemorrhagic events.
Background/Aims: This study evaluates endoscopic choroid plexus coagulation, in conjunction with third ventriculostomy when technically feasible, as a strategy to treat patients with hydranencephaly or hydrocephalus with a minimal cortical mantle. Methods: We retrospectively reviewed patients with hydranencephaly (n = 4) or hydrocephalus with the cortical mantle <1 cm in maximal thickness (n = 4) who underwent endoscopic choroid plexus coagulation from 2007 to 2010. Endoscopic third ventriculostomy was performed simultaneously when technically feasible (in 3 of 8 patients). Endoscopic management was considered successful if a shunt was not subsequently required. Results: Endoscopic management was successful in 4 of 8 patients (50%) who did not require a shunt over a median follow-up period of 15 months (range 2.5–24). Four patients (50%) failed endoscopic management and required a shunt 1 month to 11 weeks after endoscopic surgery. One patient died 4 days after shunt placement due to pneumonia and renal failure. Three of 4 patients who had a successful endoscopic procedure ultimately died of causes that were likely unrelated to hydrocephalus (pneumonia in 2 patients and sudden infant death syndrome in 1 patient). Besides failure to control hydrocephalus adequately in 4 patients, there were no additional complications noted after endoscopic surgeries. Conclusion: Endoscopic choroid plexus coagulation can enable some infants with hydranencephaly or massive hydrocephalus to avoid a ventriculoperitoneal shunt.
Epidural anesthesia is a versatile technique widely used in treating lumbar spinal pain syndromes. Complications during these procedures can arise either from needle placement or from administration of medication. Potential risks include infection, hematoma, intravascular or subdural injections of medication, direct nerve trauma, air embolism, entry into a disc space, urinary retention, radiation exposure, and hypersensitivity reactions. The objective of this article is to review the complications of lumbar epidural injections and discuss the potential pitfalls related to these procedures. We searched Medline comprehensively for relevant case reports, clinical trials, and review articles. Complications from lumbar epidural injections are extremely rare. Most if not all of them can be avoided by careful techniques with accurate needle placement, sterile precautions, and a thorough understanding of the relevant anatomy and contrast patterns on fluoroscopic imaging.

Purpose Despite an overall reduction in the number of stroke cases presenting to hospitals during the COVID-19 pandemic, a remarkably high incidence of acute cerebrovascular disease associated with the infection has been reported. In this systematic review, we assess the neurological outcomes and complications of endovascular thrombectomy (EVT) for large vessel occlusions (LVO) in COVID-19 patients. Methods A literature search was performed in PubMed from December 1, 2019 through September 1st, 2020 using different combinations of suitable keywords. Ten studies reporting EVT outcomes and complications were identified. Two studies that included non-LVO pathologies and COVID-19 negative patients with the outcomes analysis were excluded. Patient demographics, comorbidities, anatomic thrombus location, neurological and angiographic outcomes were assessed. Results A total of 8 studies, in addition to our institutional case series, were ultimately included in this review. The mean age was 62.2 years, of which 67.6% were males. M1 segment involvement was the most commonly reported (53.8%) thrombus location. The mean NIHSS at presentation was 20.4 with no significant change at 24 h. Successful revascularization (TICI ≥ 2b) was achieved in 89%. Early proximal cerebral re-occlusion was reported in 6 patients (11%) and cerebral hemorrhage in 3 patients (4%). In hospital mortality was reported in 15 patients (28.8%). Conclusion Despite angiographically successful EVT of LVOs in the majority of patients, this literature analysis demonstrates overall poor outcomes and high mortality in COVID-19 patients post EVT. An unusual incidence of early intracerebral proximal arterial re-occlusion was notable.
Cavernous angiomas usually occur in the parenchyma of both the supra and infratentorial compartments. At times, they can both clinically and radiologically mimic other dural-based lesions. We present a case of a patient with chronic occipital headaches, initially thought to have a meningioma, but proven to be a cavernoma with histological analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
