RÉSUMÉ
OBJECTIVE: Patients with cerebral venous sinus thrombosis (CVST) may die during the acute phase due to increased intracranial pressure and cerebral herniation. The purpose of this study was to assess the role of decompressive craniectomy in the treatment of patients with malignant CVST. METHODS: Patients who underwent decompressive craniectomy and were consequently admitted to the Critical Care Unit, Department of Neurosurgery, at Capital Medical University Xuanwu Hospital from March 2010 to January 2021 were retrospectively examined with follow-up data at 12 months. RESULTS: In total, 14 cases were reviewed, including 9 female and 5 male patients, aged 23-63 years (42.7 ± 12.3 years). Prior to surgery, all patients had a GCS score <9. 6 patients had a unilateral dilated pupil, while 4 patients had bilateral dilated pupils. According to the head computed tomography (CT), all patients had hemorrhagic infarction, and the median midline shift was 9.5 mm before surgery. Thirteen patients underwent unilateral decompressive craniectomy, and 1 patient underwent bilateral decompressive craniectomy, among whom, 9 patients underwent hematoma evacuation. Within 3 weeks of surgery, 3 cases (21.43%) resulted in death, with 2 patients dying from progressive intracranial hypertension and 1 from acute respiratory distress syndrome (ARDS). Eleven patients (78.57%) survived after surgery, of whom 4 (28.57%) patients recovered without disability at 12-month follow-up (mRS 0-1), 2 (14.29%) patients had moderate disability (mRS 2-3), and 5 (35.71%) patients had severe disability (mRS 4-5). CONCLUSIONS: Emergent decompressive craniectomy may provide a chance for survival and enable patients with malignant CVST to achieve an acceptable quality of life (QOL).

OBJECTIVE: To investigate the correlation between expressions of MMP-2 and NF-κ B in the intracranial aneurysm wall, and explore their role in the mechanism of the occurrence, growth and rupture of intracranial aneurysms. METHODS: RT-PCR was used to detect the expression of MMP-2 and NF-κ B mRNA of 30 cases of intracranial aneurysm tissue and 10 cases of normal intracranial arterial tissue; Immunohistochemical method was used to detect the expression of MMP-2 and NF-κ B protein. RESULTS: The semi-quantitative analysis of MMP-2 and NF-κ B in aneurysms tissues and normal tissues were statistically significant different from each other (P<0 05). Immunohistochemical staining results showed NF-κ B was expressed in different layers. The expression of them were positive in intimal and medial, and the expression sites were located in the nucleus. MMP-2 were expressed in different layers of the aneurysm wall, and the expressions were positive in media and extima. The MMP-2 and NF- κ B-positive expression of aneurysm wall were significantly higher than in normal cerebral arteries (P <0.05). MMP-2 and NF-κ B mRNA expression showed positive correlation in the aneurysm wall tissue (r = 0.689, P = 0.005). CONCLUSIONS: The expressions of MMP-2 and NF-κ B in the intracranial aneurysm wall tissue were significantly higher than in the normal intracranial arterial tissues. They have a synergistic effect on the formation of intracranial aneurysms.
