Abstract

Background: Decompressive hemicraniectomy reduces secondary brain injury related to brain edema and increased intracranial pressure (ICP) in patients with malignant middle cerebral artery infarction (MMI). However, a substantial proportion of patients still die despite hemicraniectomy due to refractory brain swelling. Objective: We aim to investigate whether ICP measured immediately after hemicraniectomy may indicate decompression effects and predict survival in patients with MMI. Methods: We included 25 patients with MMI who underwent ICP monitoring and brain computed tomography within the first hour of hemicraniectomy. Midline shifts were measured as radiological surrogates of decompression. The Glasgow Coma Scale and pupillary enlargements during the first day after hemicraniectomy were assessed as clinical surrogates of decompression. Long-term survival status at 6 months was used as the final outcome. We analyzed the relationships between early ICP and findings of midline shift, Glasgow Coma Scale, pupillary enlargement, and survival. Results: Initial ICP was correlated with mean ICP (P < .001) and maximal ICP (P < .001) during the first postoperative day. Intracranial pressure was associated with midline shifts (P = .009), lower Glasgow Coma Scale scores (P = .025), and the pupillary enlargement (P = .015). Sixteen (64.0%) patients survived at 6 months. In a Cox proportional hazard model, elevated ICP was associated with mortality at 6 months (hazard ratio: 1.13; 95% confidence interval: 1.03-1.24; P = .008). Conclusion: Increase in ICP soon after hemicraniectomy was associated with midline shift, poor neurological status, and mortality in patients with MMI. Measurements of ICP soon after hemicraniectomy may permit earlier interventions as well as more refined clinical assessments. [ABSTRACT FROM AUTHOR]

Abstract

The article presents a case study of 79-year-old man with a lung mass underwent computed tomography (CT)-guided biopsy. Topics discussed include ischemic penumbra and blood-brain barrier disruption in cerebral air embolism; hyperoxygenation therapy to remove air and mitigate ischemia; and oxidative stress due to hyperoxic reperfusion via a disrupted blood–brain barrier.

86. New ischemic lesions coexisting with acute intracerebral hemorrhage

Author

Kang, Dong-Wha, Han, Moon-Ku, Kim, Hye-Jin, Yun, Sung-Cheol, Jeon, Sang-Beom, Bae, Hee-Joon, Kwon, Sun U., and Kim, Jong S.

Abstract

Acute cerebral infarction may coexist with hypertensive intracerebral hemorrhage (ICH) because lacunae and hypertensive ICH share common risk factors and small-vessel pathology. We sought to determine the frequency and predictors of new ischemic lesions (NIL) on diffusion-weighted imaging (DWI), in patients with acute hypertensive ICH, and to investigate whether NIL predicts subsequent clinical cerebrovascular events.

87. 721: MEASLES-INDUCED ENCEPHALITIS.

Author

Subjects
*ENCEPHALITIS, *INTENSIVE care units
Abstract

Measles virus may cause several types of encephalitis, including primary measles encephalitis, acute post-measles encephalitis, measles inclusion body encephalitis, and subacute sclerosing panencephalitis. On follow serological tests performed a week later, serum titers of anti-measles IgG increased more than 15 times from the baseline value (>300), whereas serum titers of anti-measles IgM became undetectable. We believe that the patient developed acute post-measles encephalitis, rather primary measles encephalitis, because of the temporal profile of serological tests, the development of encephalitis symptoms soon after resolution of measles symptoms, and a good response to corticosteroid therapy.

Abstract

Acute multiple infarcts in multiple cerebral circulations (AMIMC) are thought to suggest the presence of cardioembolic sources or systemic hypercoagulopathy. However, the mechanism and the simultaneous occurrence of AMIMC are not well known. We reviewed 685 consecutive acute ischemic stroke patients who underwent diffusion-weighted imaging (DWI) within 48 hours of onset. AMIMC was defined as multiple acute DWI lesions distributed in more than one cerebral circulation (i.e., 2 anterior and 1 posterior circulations). Signal intensities on apparent diffusion coefficient (ADC) maps corresponding to acute DWI lesions were classified as 'low', 'iso-' or 'high' signals. Blood markers obtained within 24 hours after admission were compared between patients with and without AMIMC. Sixty-seven (9.8%) patients had AMIMC. Frequency of cardioembolism in AMIMC patients was only 29.9% (20/67), which was not different from non-AMIMC patients (21.7%, p = 0.16). Large-artery atherosclerosis (LAA) or small-vessel occlusion (SVO) in multiple circulations or combined LAA and SVO were identified in 34.3% (23/ 67) of AMIMC patients, although pure LAA and pure SVO were less frequent than in non-AMIMC patients. ADC signals were purely 'low' in 38 (56.7%) and 'mixed' (low with iso- or high) in 29 (43.3%). Cardioembolism tended to be associated with 'low' ADC signals (75.0%) compared with other stroke mechanisms (48.9%; p = 0.062). C-reactive protein was higher in AMIMC than in non- AMIMC patients (p = 0.009). Stroke mechanisms responsible for AMIMC are heterogeneous. ADC findings suggest that AMIMC commonly occur stepwise and may be useful in determining stroke mechanism. Systemic inflammation may be associated with the pathogenesis of AMIMC.
