ABSTRACT
Objective To develop a simple, fast and accurate preoperative planning method for endoscopic surgery of patients with hypertensive intracerebral hemorrhage (HICH).Methods Eighteen patients with HICH, admitted to our hospital from June 2008 to August 2010, were performed endoscopic minimally invasive surgery; CT three-dimensional reconstruction was employed to locate the intracerebral hematoma and select the appropriate endoscopic approach before the endoscopic surgery.The clinical data and treatmem efficacy were analyzed.Results According to the results of CT three-dimensional reconstruction, our neurosurgeons could design the best endoscopic approach; the three-dimensional relationship between intracerebral hematoma and scalp markers was shown directly and accurate positioning of the location of drilling was achieved; therefore, the time for preoperative preparation, anesthesia and operation was shortened. The mean operating time of these 18 patients was about 1.5 h; the volume of blood loss was only 30-40 mL; and the evacuation ratio was about 89.2%.After the elimination of hematoma, the brain tissues were flabby, so decompressive craniectomy was not needed. Conclusion CT three-dimensional reconstruction is a simple, fast and accurate preoperative planning method for endoscopic surgery of patients with HICH.
ABSTRACT
Objective To develop a minimally invasive operating technique for the treatment of hypertensive thalamic hemorrhage. Methods The clinical data of 15 patients with hypertensive thalamic hemorrhage performed neuroendoscope-assisted micro-invasive surgical treatment in our hospitals from July 2007 to June 2010 were retrospectively analyzed; their treatment efficacy were also concluded. Results The mean operation time of these patients was (1.5±0.4) h and the amount of blood loss was 30-40 mL; the mean clearance rate of hematoma in the thalamus was (86.2 ±7.9)percentage. Patients were followed up and evaluated by Glasgow outcome scale for at least 3 months.Three patients (21.4%) showed good recovery, 4 (28.6%) moderate disability, 4(28.6%) severe disability and 2 (14.3%) vegetative survival; 1 patient (7.1%) died. Conclusion Neuroendoscope-assisted micro-invasive surgical treatment is a fast and minimally invasive operating technique with little blood loss in the treatment of hypertensive thalamic hemorrhage.
ABSTRACT
Objective To assess the effect of D-JNKI1, an inhibitor of c-Jun N-terminal kinase (JNK), on delayed neuronal death (DND) in a gerbil model of transient global cerebral ischemia, so as to further study the roles of JNK activation in mediating neuronal cell death in brain ischemia. Methods Fifty-five Mongolian gerbils were randomly divided into 11 groups. Animals (n=35) assigned into 7 groups (n=5 per group) were subjected to 5-min occlusion of bilateral common carotid arteries (BCCAO);among the 7 groups, different doses of D-JNKI1 (0.00012, 0.0012, 0.012, 0.12, 1.2 μmol/L in 2 μL PBS,n=5 each) were administered stereotaxically into right lateral ventricles 3 h after reperfusion; the control group (n=5) received 2 μL PBS; and another group (n=5) received 1.2 μmol/L of D-JNKI1 in 0.5 mL PBS intraperitoneally. Sham-operated animals (n=5) only received the exposure of bilateral common carotid arteries without occlusion. Three groups (n=5 in each) were pretreated with D-JNKI1 (0.00012,0.0012 μmol/L in 2 μL PBS) or only 2 μL PBS 30 min before 2-min BCCAO, and subjected to 5-min BCCAO 48 h after the first ischemic insult. All animals were sacrificed 4 d after 5-min BCCAO and prepared for frozen section and Nissl staining. Results The treatment with D-JNKI 3 h after 5-min ischemia was neuroprotective with a maximum effect at a dose of 0.0012 μmol/L. Pretreatment with D-JNKI augmented ischemic tolerance induced by 2-min ischemia. Conclusion D-JNKI1 has a potential neuroprotective effect on DND in CA1 of hippocampus in gerbils with global cerebral ischemia-reperfusion injury.
