RESUMO
Objective:To investigate the impact of severe stenosis or occlusion of intracranial artery in anterior and posterior circulation on cognitive function in patients.Methods:Patients with Alberta stroke program early CT score(ASPECTS) and posterior circulation ASPECTS(pc-ASPECTS) of 10 were selected, and neuropsychological assessments were performed in 30 patients with intracranial artery severe stenosis or occlusion in anterior posterior circulation (anterior circulation group)and 23 patients with intracranial artery severe stenosis or occlusion in posterior circulation(posterior circulation group) and 53 control subjects using MMSE, MoCA and multidimensional psychological assessment system.Results:The scores of time orientation(control group: 5.00(5.00, 10.00), anterior circulation group: 5.00(5.00, 5.00), posterior circulation group: 5.00(5.00, 5.00)), attention (control group: 6.00(5.00, 6.00), anterior circulation group: 5.00(4.00, 6.00), posterior circulation group: 5.00(4.00, 6.00)) and word discrimination test (control group: 70.00(60.00, 82.00), anterior circulation group: 48.00(20.50, 67.50), posterior circulation group: 53.50(33.25, 75.25)) were significantly lower in patients of anterior circulation group and posterior circulation group than those of control group(all P<0.05); The scores of memory(control group: 3.00(2.00, 3.00), anterior circulation group: 2.00(1.00, 3.00), MMSE(control group: 29.00(28.00, 30.00), anterior circulation group: 28.00(26.75, 29.00)) and simple subtraction(control group: 72.00(53.50, 85.50), anterior circulation group: 53.50(37.00, 73.00)) were significantly lower in patients of anterior circulation group than those of control group(all P<0.05); The scores of visuospatial executive function(control group: 4.00(3.00, 5.00), posterior circulation group: 3.00(2.00, 4.00)) and digital sequence reasoning(control group: 74.50(51.50, 83.00), posterior circulation group: 42.00(28.00, 70.00)) were significantly lower in patients of posterior circulation group than those of control group(all P<0.05); The scores of spatial working memory test(control group: 77.50(51.75, 89.00), anterior circulation group: 56.50(34.00, 72.50), posterior circulation group: 31.00(18.50, 58.00))were significantly lower in patients of posterior circulation group than those of the other two groups(all P<0.05). Conclusion:Severe stenosis or occlusion of intracranial arteries in anterior and posterior circulation is associated with cognitive impairment in patients.Vascular lesions in different parts can lead to cognitive impairment in different aspects.
RESUMO
Objective:To evaluate the safety and efficacy of endovascular interventional treatment of the intracranial vertebrobasilar trunk large aneurysms (VBTLAs) compared with conservative treatment.Methods:This is a prospective multi-center cohort study. From October 2012 to October 2018, a total of 69 patients with intracranial vertebrobasilar trunk large aneurysm (diameter>10 mm) from Henan Province People's Hospital and People's Liberation Army Rocket Medical Center were included in this study. Patients themselves chose either endovascular interventional therapy (interventional group) or conservative treatment (conservative group) after discussion with their doctors. The χ 2 test was used to compare the incidence of deaths, stroke, and all other serious adverse events including other site bleeding, myocardial infarction and others between the two groups. Results:A total of 69 patients were enrolled, of whom 51 patients were enrolled in interventional group, 18 patients underwent endovascular reconstructive therapy, 11 patients underwent deconstructive therapy, and 4 patients underwent conjunction interventional treatments. Eighteen patients were enrolled in conservative group, of whom 11 cases received simple risk factor control, 7 cases received antiplatelet and risk factors control. The proportions of hypertensive patients 94.4% (17/18) and giant aneurysms 50.0% (9/18) in the conservative group were higher than those in the surgery group 64.7% (33/51, χ 2=4.500, P=0.034), 19.6% (10/51, χ 2=4.730, P= 0.030).The incidence of all serious adverse events associated with protocol was 15.7% (8/51) in the interventional group and 44.4% (8/18) in the conservative group [risk ratio (RR) =0.353, 95% confidence intervals (CI): 0.156-0.801], and the difference was significant (χ 2=4.668, P=0.031). The incidence of fatal events associated with protocol was 2.0% (1/51) in the interventional group and 38.9% (7/18) in the conservative group (RR=0.050, 95%CI: 0.007-0.382), and the difference was significant (χ 2=14.281, P<0.001). The incidence of hemorrhage events associated with protocol was 2.0% (1/51) in the interventional group and 22.2% (4/18) in the conservative group (RR=0.088, 95%CI: 0.011-0.738), and the difference was significant (χ 2 =5.391, P=0.020). Follow-up imaging showed that the occlusion rate of aneurysms in 44 patients in the interventional group was 56.8% (25/44) after a median follow-up of 6 months. Imaging follow-up was obtained in 9 patients, whose occlusion rate of aneurysms was 0 and the median follow-up time was 12 months, in the conservative group. The difference was significant(χ 2 =7.534, P=0.006). Conclusion:Compared with conservative treatment, endovascular intervention of the intracranial VBTLAs has lower incidences of serious adverse events and death events.
RESUMO
Objective To evaluate the benefits and the risk of pulmonary embolism between walking exercises and bed rest in the acute stage of deep venous thrombosis (DVT). Methods From February 2008 to March 2009,40 acute primary DVT patients were arbitrarily randomized into controlled group and experimental group,with 20 cases in each group,who were hospitalized within seven days of onset.Patients in controlled group underwent bed rest for 7-10 days,wearing elastic stockings.While patients in experimental group were early (1-2 days after admission) off bed walking about 600-1200 m every day with elastic stockings for 7-10 days.During the process patients in both group received regular anticoagulation treatment,and continued warfarin anticoagulation therapy after out of hospital for at least 6 months.The clinical characteristics of the two groups were comparable.Primary end points were the reduction of pain assessed daily with the Visual Analogue Scale (VAS),the reduction of leg circumference at thigh,and cumulative pulmonary embolism incidences of two groups in three months. Results Symptoms in all patients of the two groups were improved,but the pain level showed a statistically significant reduction starting after the third day(58 ±8) mm in the experiment group and after the fifth day (58 ± 13) mm in the controlled group.The leg circumferences of the two groups after 7 days were statistically significantly different (P ＜ 0.05),the cumulative pulmonary embolism incidences of the two groups for 3 months were not statistically significantly different. Conclusion Mobile patients with acute DVT should be encouraged to walk with medical compression stockings.The rate of resolution of pain and swelling is significantly faster when the patient ambulates with compression.The quality of life significantly improved.The risk of pulmonary embolism does not significantly increase by this approach.
