J Korean Neurosurg Soc 48 : [371][372][373][374] 2010 Cysticercosis is the most common parasitic infection affecting the central nervous system. Spinal neurocysticercosis (NCC) is very rare compared with intracranial NCC and requires more aggressive management because these lesions are poorly tolerated. The authors report a case of intradural extramedullary cysticercosis of the entire level of spine with review of the literature.
The aim of this study was to evaluate the clinical effect of a continuous infusion of urokinase in cerebral stoke patients who were late admitted over 6 hours after onset. From January to December in 2008, acute cerebral stroke patients (n=143) treated with intravenous urokinase infusion (Group I, n=93) or not (Group II, n=50) after 6 hours and within 72 hours of stroke onset were reviewed. Continuous intravenous infusion of urokinase was done for 5 days. The clinical outcome for each patient was evaluated by using the modified National Institutes of Health Stroke Scale (NIHSS) on admission and on the day of discharge. The NIHSS score was decreased at discharge compared with admission in the urokinase treatment group (Group I; from 4.8±2.2 to 3.8±1.9; p=0.002). There was an improvement in the patients who initiated urokinase treatment within 24 hours from stroke onset in Group I (from 5.1±1.9 to 3.9±1.5; p=0.04). In patients with initiated urokinase treatment within 24 hours from stroke onset, intravenous urokinase infusion could be an effective modality in acute ischemic stroke patients admitted later than 6 hours after onset.
The authors introduced a new approach for clipping of the incidental aneurysm of the middle cerebral artery (MCA) and reported the clinical results. We retrospectively reviewed 26 patients with 27 incidental MCA aneurysms who were treated from January 2010 to December 2012. All clippings were performed through a small temporal craniotomy and linear skin incision. Follow-up imaging showed complete occlusion of 26 aneurysms (96.3%), residual neck in one (3.7%). In one case, residual neck of the aneurysm did not grow on serial follow up. In one of 26 cases (3.8%), approach-related complication was retraction injury of the temporal cortex. Two patients developed postoperative infarction on the MCA territories due to vasospasm and on the cerebellum due to unknown causes. These were not approach-related complications. Operation time was 95 min-250 min (mean 143 min). There were no complications of temporal muscle atrophy, scar deformity, paresthesia, or pain around the scalp incision and frontalis palsy. This approach offers good surgical possibilities and little approach related morbidity in the clipping of incidental MCA aneurysms.
ObjectiveTo report an observational investigation of small high attenuated foci in computed tomography (CT) scan followed by brain parenchymal catheterization.MethodsFrom January 2011 to March 2015, we retrospectively reviewed the 381 patients who had undergone brain catheterization in our clinic and enrolled the patients who had newly developed high attenuation foci in the postoperative CT scans. The brain CT scans were reviewed about the lesion location, Hounsfield Unit (HU) and the time of appearance.ResultsTwenty seven of 381 patients had high attenuation foci in CT scans after the procedure. The location of high density lesions was as follows: parenchyma in 9 (33.3%) cases, ventricle in 5 (18.5%), combined in parenchyma and ventricle in 13 (48.1%). The lesions were identified in the catheter tract in parenchymal type, and catheter-lodged frontal horn or choroid plexus in ventricular type. We could not find the calcific foci before the catheter removal, and those were found after removal in all cases. The time of appearance after the removal was variable from 0 to 14 days (mean 4.2, median 3). The regular rules of HU change in CT scans were not found as times go on.ConclusionThe high attenuation foci in CT scans were bone dust originated from skull during operation. Although these lesions did not make troubles, we should clean the operation field before the insertion of brain catheter and we may use another material, like Surgicel to seal up the burr hole instead of bone dust in the end of operation.
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.
