Advances in the clinical diagnosis and treatment of intracranial venous sinus thrombosis / 中国医师进修杂志

Intracranial venous sinus thrombosis is a special type of cerebral vascular disease. It usually originates from the later period of wasting disease, brain trauma, puerperium, blood disease, heart disease, eye/nasal/facial infection, meningitis and septicemia. It occurs in different age and sex. Infants, young children, frail elderly people, postpartum women, chronic disease patients are prone to be affected.Because of lacking of typical clinical manifestations, the clinical diagnosis and treatment of this disease is difficult and easily leading to misdiagnosis and mistreatment, which affects the prognosis of the patients.Because of lacking of standardized diagnosis and treatment strategy, different methods are needed. According to the proceeding reports, we reviewed the current progress of the diagnosis and treatment of intracranial venous sinus thrombosis.

Mechanical thrombectomy with the Solitaire AB device in acute ischemic stroke of posterior circulation: a series of 17 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of mechanical thrombectomy with the Solitaire AB device in recanalization of patients with acute ischemic stroke of posterior circulation.</p><p><b>METHODS</b>The clinical data of 17 consecutive patients with acute ischemic stroke of posterior circulation, treated with the Solitaire AB device from August 2011 to August 2015 in Department of Neurosurgery, the Military General Hospital of Beijing People's Liberation Army, were extracted and then retrospectively analyzed. There were 12 male and 5 female patients with a median age of 60 years (ranging from 44 to 75 years). Among them, 8 cases occluded in basilar artery, 4 cases occluded in vertebral artery and 5 cases occluded in vertebral plus basilar artery. Recanalization rate as well as complications after treatment were analysized. Also, neurological functions of the patients before and after treatment, measured by National Institute of Health stroke scale (NIHSS) score, were compared via t test and the clinical outcomes were assessed by modified Rankin score (mRS) at 90 days after treatment.</p><p><b>RESULTS</b>Fifteen patients resulted in successfully recanalization, and 2 cases failed both of whose onset to sheath time were above 7.5 hours. The NIHSS score at 7 days was 11±10, which was significantly decreased compared to the admission NIHSS score 17±5 (t=2.949, P=0.009). No symptomatic intracranial hemorrhage case was found after thrombectomy. At 90 days, one patient died(mRS 6), one patient seriously disabled (mRS 5), two patients moderately seriously disabled (mRS 4), four patients resulted in moderate outcome (mRS 3) and the other 9 patients achieved good outcome (mRS 0 to 2). The dead and seriously disabled cases were both due to failure in recanalization. Two moderately seriously disabled cases were probably attributed to their severe admission condition (NIHSS >20) and prolonged time (onset to sheath time >6 hours).</p><p><b>CONCLUSION</b>Mechanical thrombectomy with the Solitaire AB device contributes to a high rate of recanalization with a low probability of complication and improves functional outcome in patients with acute ischemic stroke of posterior circulation.</p>

Impact of diabetes and stress hyperglycemia on thrombolytic effect and prognosis in patients with acute cerebral infarction / 中国脑血管病杂志

Objective To observe the impact of diabetes and stress hyperglycemia on thrombolytic effect and short-term prognosis in patients with acute cerebral infarction. Methods A total of 127 patients with acute cerebral infarction (≤4. 5 h) who received thrombolytic therapy with alteplase at General Hospital of Beijing Military Command from January 2012 to August 2013 were enrolled retrospectively. They were divided into three groups:Diabetes group (n=35),stress hyperglycemia group (n=49),and normal glucose group (n=43) according to whether they had a history of diabetes,random glucose on admission, and oral glucose tolerance test at day 7. At 24 h after thrombolysis,the National Institute of Health Stroke Scale (NIHSS) scores,recanalization rate,and the modified Rankin Scale (mRS) scores at day 90 were compared between the 2 groups. Results Before thrombolysis,the NIHSS scores of the diabetic group, stress hyperglycemia group,and normal glucose group were 14. 2 ± 5. 1,12. 8 ± 5. 6,and 13. 0 ± 4. 6,respectively (P>0.05);at 24 h after thrombolysis,they were 14.7 ±6.0,11.9 ±4.9,and 8.0 ±2.9,respectively (P0. 05);the NIHSS score of the normal glucose group was lower than before thrombolysis. There was significant difference (P <0. 05). After thrombolysis,the patients with good recanalization were 54. 3% (n=19),57. 1% (n=28),and 67. 4% (n=29),respectively in the three groups;the hemorrhagic conversion rate was 14. 3% (n=5),6. 1% (n=3),and 2. 3% (n=1),respectively. There were no significant differences. At day 90 after thrombolysis,the mRS scores in the 3 groups showed that the good prognosis rate of the normal glucose group was 72. 1% (n=31);it was significantly higher than 51. 0% (n=25) of the stress hyperglycemia group and 29. 6% (n=10) of the diabetes group. There were significant differences (P<0. 05,P<0. 01). There was also significant difference between the stress hyperglycemia group and the diabetes group. Conclusion Diabetes and stress hyperglycemia have varying degrees of adverse effects on the efficacy and prognosis of the thrombolytic therapy for acute cerebral infarction.

Hyper-early embolotherapy in treatment of intracranial ruptured aneurysm / 中国医师进修杂志

Objective To explore the clinical efficacy and safety of hyper-early embolotherapy in treatment of intracranial ruptured aneurysm.Methods A retrospective analysis was made on 33 patients with intracranial ruptured aneurysm.Preoperative Hunt-Hess grade:grade Ⅰ-Ⅱ in 16 patients,gradeⅢin 5 patients,grade Ⅳ in 9 patients,grade Ⅴ in 3 patients.All patients were confirmed with subarachnoid hemorrhage (SAH) by angiography and then underwent embolization under general anesthesia by detachable coils within 6 h from onset.Results After operation,25 patients (75.8％) recovered well,4 patients (12.1％) were with mild disability with paralysis and aphasia,4 patients (12.1％) were dead (1 patient for intraoperative aneurysm rupture,1 patient for postoperative pneumonia,1 patient for infection of hematoma at puncture site and 1 patient for postoperative gastrointestinal bleeding).Followed up 1-6 months,no rebleeding occurred.Conclusions Hyper-early embolotherapy could avoid rebleeding of the aneurysm,and relieve the vasespasm,without increasing the intra-operative rebleeding rate.Moreover hyper-early embolotherapy could greatly decrease the mortality of poor-grade SAH patients.

Role of matrix metalloproteinase-9 dynamic expression in the development of early vascular restenosis after carotid endarterectomy / 中国组织工程研究

BACKGROUND: Vascular restenosis alter carotid endarteractomy (CEA) is an important factor affecting curative affect ofoperation.OBJECTIVE: To explore the role of matrix metalloproteinase-9 (MMP-9) mRNA dynamic expression in the development of early vascular restenosis after carotid endarterectomy.DESIGN, TIME AND SETTING: A random grouping contrast observation was completed in the General Hospital of Beijing Military Area Command of Chinese PLA from February 2006 to December 2007. MATERIALS: Forty-one healthy male New Zealand rabbit, weighing about 3.0 kg, with 36 ones used for preparing carotid atherosclerotic stenosis (CASS) models. experimental group, each 6 of the CASS rabbit models (n =36) were selected at the time points of hour 4, day 1, 3, 7, 30, and 90 following CEA respectively. Then they were fixed with 40 g/L polyoxymethylene perfusion and stained with hematoxylin-eosin to observe their morphologic changes.MAIN OUTCOME MEASURES: The expression changes of MMP-9 mRNA were observed dudng the development of early vascular restenosis by the quantitative real-time polymerase chain reaction technique preoperatively as well as at day 1, 3 and 7 following CEA.RESULTS: Several stages could be seen in the reparative process of neointima after CEA, including the thrombosis, the inflammatory reaction, the repair of endothelium, the proliferation of vascular smooth muscle call, the formation and accumulation of extracellular matrix. MMP-9 mRNA was expressed since day 1, reached a peak at day 3 and then decreased significantly at day 7 postoperatively.CONCLUSION: MMP-9 plays an important role in the proliferation, migration and reconstruction of vascular smooth muscle calls, the mediated reconstruction of local blood vessels, as well as the development of vascular restenosis.

CT finding is an index in assessment of outcome in patients with diffuse traumatic brain swelling / 中华创伤杂志(英文版)

OBJECTIVE: To assess the relationship between the prognosis of the patients with diffuse traumatic brain swelling (DTBS) and the changes of the ventricles and the cisterns in CT scans. METHODS: The outcome of the patients with DTBS and the changes of the ventricles and the cisterns in CT scans were studied and analyzed in a group of 268 cases. We focused on the changes of the third ventricle and the basal cistern, age and Glasgow Coma Scale (GCS). RESULTS: Of 268 cases, there were changes of the third ventricle and/or the basal cistern in 124, 65 died. In l8 cases, the third ventricle and the basal cistern were both absent and l6 died (88.9%). The third ventricle changed significantly in 59 cases, 33 died (55.9%), while the basal cistern changed in 47 cases and 16 died (34%). Of the 124 patients with changes of the third ventricle and/or the basal cistern, 26 were children, 8 died; 98 adults, 57 died. CONCLUSIONS: For patients with DTBS, the outcome was in direct correlation with the change of the third ventricle and/or the basal cistern, the change of the third ventricle was much more important in assessment of the outcome than that of basal cisterns. There is no significant difference in, the incidence of DTBS between children and adults while the outcome of children is much better than that of adults. The patients with the changes of the third ventricle and the basal cistern accompanied with lower GCS scores have poor outcome.
