We will assign two investigators to independently search allpotential citations, extracted data, and appraised risk of bias accordingly, and then STATA software version 12.0 will beused to statistically analyze all data.Ethics and dissemination： The ethics approval and patient written informed consent will not be required because allanalyses in the present study will be performed based on data from published studies. We will submit our systematicreview to a peer-reviewed scientific journal for publication.展开更多

Liquid aneurysmal embolic materials represented by cellulose acetate polymer (CAP) are still in controversy. In this research, t he embolization results and pathological reactions after embolization of canine aneurysmal models with EDC or CAP were observed and compared. Methods. The canine aneurysmal models constructed by anastomosis of venous pouch es were randomly grouped. The aneurysms were respectively occluded with CAP and electrolytic detachable coils that was named by Wu electrolytic detachable coil (WEDC) and made by us. Angiogram follow ups were performed at 24 hour, 2 week , and 2 month after embolization. The occluded aneurysms were dissected in each stage for light microscopic, electron microscopic, and histochemical research. Results. The effect of embolization was significantly better with WEDC than that with CAP . Post embolized complications such as aneurysm rupture and stenosis of parent arteries could only be found in CAP group. Pathol ogical research showed that CAP mass could packed the aneurysms more densely tha n coils. Acute chemical damage of aneurysmal wall and inflammatory cell infiltra tion was prominently found in early stage after CAP embolization. Organization of thrombus inside aneurysms and formation of endothelial tissue over the orific es of aneurysmal necks could be found in both groups 2 months after embolization . But parts of coils might be exposed outside endothelial layer. Conclusions. EDC are still the most safe, efficient, and reliable instruments to embolize aneurysm. CAP should be improved further to solve the problem of stron g chemical corrosion and difficulty in control before it is widely used.展开更多

Methods: A retrospective study was performed in 66 cases of acute posttraumatic BS. There were 3 groups based on computered tomography (CT) scanning: 23 cases of hemisphere brain swelling (HBS) with middle line shift for less than 5 mm within 24 hours (Group A), 20 with middle line shift for more than 5 mm (Group B), and 23 with bilateral diffuse brain swelling (Group C). Results: (1) The mortality rates of the operative and nonoperative management in Group A, Group B, and Group C were 20.0%, 31.6%, and 75.0% versus 44.4%, 0, and 85.7%, respectively (P> 0.05); while the rates in subgroups with different middle line shift (more than 5 mm and less or equal 5 mm) were 29.2% and 75.0% versus 75.0% and 44.4%, respectively ( 0.05>P> 0.01). (2) The good recovery rate and mortality in Group A were 47.8% and 39.1%, respectively and in Group C, 8.7% and 78.3%, respectively. There was a very significant difference between Group A and Group C (P< 0.01). (3) The total survival rate of the selective comprehensive therapy was 53.1%. Conclusions: (1) Acute posttraumatic BS needs to be diagnosed correctly and promptly with CT scanning within 4 hours. (2) For patients with midline shift for more than 5 mm, especially with thin-layered subdural hematoma, surgical intervention is essential to reduce the fatality of acute posttraumatic BS.展开更多

Methods： The clinical data of a group of 136 severely brain-injured patients admitted to Shanghai Neurosurgical Emergency Center from December 2004 to February 2006 were studied. Results： The intraventricular ICP monitor was placed in all the 136 patients via Kocher＇s pathway, Paine＇s pathway or intraoperative opened ventricle. In this series, the probe was placed during the procedure of craniotomy in 98 patients; for other 38 patients, the probe was placed initially to measure or to monitor ICE A stepwise protocol targeting at ICP control （420 mm Hg） and optimal cerebral perfusion pressure （CPP） maintenance （60-90 mm Hg） was deployed.Among them, 76 patients survived with good recovery, 14 with moderate disability, 24 with severe disability, 10 with vegetative state, and 12 died. Complications associated with intraventricular ICP monitoring included hemorrhage and infection. Hemorrhage occurred in 1 patient and infection in 5 patients. There were no unacceptable complications related to ICP monitoring. Conclusions： Ventricular access for 1CP monitoring can be safely and accurately achieved. ICP monitoring via ventriculostomy may facilitate an early and accurate intervention for severely brain-injured patients. The intraventricular ICP monitoring is a low-risk procedure and can yield great benefits for management of patients with severe TBI.展开更多
