OBJECTIVETo compare the perioperative outcome between the endovascular repair (EVAR) and open surgical repair (OSR) for ruptured abdominal aortic aneurysm.

METHODSFrom January 2006 to January 2013, totally 66 patients with ruptured abdominal aortic aneurysm (rAAA) treated by surgery were retrospectively analyzed in Department of vascular surgery, People's Liberation Army General Hospital. According to the repair method, all the subjects were divided into EVAR group and OSR group. EVAR group included 40 patients, 30 patients were male, 10 patients were female, aged from 47 to 78 with a mean of (71 ± 7) years. OSR group included 26 patients, 21 patients were male, aged from 45 to 87 with a mean of (72 ± 9) years. The difference of the operation time, the amount of suspended red blood cells, ICU stay time, case fatality rate, adverse event rate and the difference of the two intervention rate were compared between the 2 groups by χ(2) test and t test.

RESULTSThere were significant differences between the 2 groups in operation time, the amount of suspended red blood cells, ICU stay time, case fatality rate, adverse event rate ((183 ± 44) minutes vs. (384 ± 108) minutes, t = -10.59, P = 0.00; (0.4 ± 0.8) units vs. (1.1 ± 1.8) units, t = -2.19, P = 0.03; (3.0 ± 1.8) d vs. (8.5 ± 5.1) d, t = -6.34, P = 0.00; 20.0% (8/40) vs. 46.2% (12/26), χ(2) = 5.10, P = 0.02; 25.0% (10/40) vs. 53.8% (14/26), χ(2) = 5.67, P = 0.02). There were no significant differences in frozen plasma quantities and the two intervention rate between the 2 groups (t = -1.98, P = 0.05; χ(2) = 0.49, P = 0.48).

CONCLUSIONSEVAR decreases the perioperative mortality and adverse event of rAAA compared with OSR. More studies are necessary to compare the middle and long-outcome between EVAR and OSR of rAAA.

Objective To evaluate iron deposition in gray matter nuclei in patients with cerebral small vessel disease(CSVD)based on quantitative susceptibility mapping(QSM)and to analyze its correlation with cognitive function.Methods Patients with CSVD attending the outpatient clinic in the Department of Neurology at Xuanwu Hospital of Capital Medical University from December 2016 to November 2022,and healthy controls recruited from previous studies in the Department of Radiology and Nuclear Medicine at Xuanwu Hospital of Capital Medical University from September 2022 to November 2022 were retrospectively consecutively collected.Baseline data of CSVD patients and healthy controls was collected and compared,including age,sex,past history(hypertension,diabetes,hyperlipidemia),smoking history,alcohol consumption history and Montreal cognitive assessment(MoCA)scale score.MRI of all CSVD patients and healthy controls were collected,including three-dimensional T1 weighted imaging,QSM,T2 weighted imaging,and fluid attenuated inversion recovery(FLAIR)sequence imaging.According to the MRI-related imaging features and CSVD total burden score,the patients were divided into mild CSVD(CSVD-m)group and severe CSVD(CSVD-s)group,and healthy controls were the control group.QSM was used to obtain the susceptibility values of gray matter nuclei for all CSVD patients and controls.One-way covariance analysis and Bonferroni correction were used to compare the gray matter nuclei susceptibility values among the three groups.Spearman correlation analysis was performed between susceptibility values of gray matter nuclei with statistically significant differences in susceptibility values and cognitive function.Results A total of 61 cases of CSVD patients were included,including 29 cases in the CSVD-s group and 32 cases in the CSVD-m group;32 healthy controls were included in the control group.(1)There was no statistically significant difference in age,sex,hypertension,diabetes,hyperlipidemia,smoking,and alcohol consumption between the CSVD-s group,CSVD-m group and control group(all P＞0.05).The MoCA scale scores of the CSVD-s group and CSVD-m group were lower than those of the control group(25.0[22.5,27.5]points,27.0[25.0,29.0]points than 28.0[27.0,29.0]points,H=15.006,P＜0.01).The difference in the imaging features distribution of cerebral microbleeds,white matter hyperintensity,and perivascular space among the CSVD-s group and the CSVD-m group was statistically significant(all P＜0.05).(2)The differences in susceptibility values of the left putamen(F=4.790),pallidus(F=12.896),hippocampus(F=3.904)and the right putamen(F=36.278),pallidus(F=39.449),caudate nucleus(F=6.797),and thalamus(F=6.525)were statistically significant among the three groups(all P＜0.05).After Bonferroni correction,the susceptibility values of the left putamen and pallidus and the right putamen,pallidus,caudate nucleus,and thalamus in the CSVD-s group were higher than those of the control group(all P＜0.05);the susceptibility values of the left pallidus and the right pallidus,putamen,and thalamus in the CSVD-m group were higher than those of the control group(all P＜0.01),and the left hippocampus was lower than that of the control group(P=0.045).(3)The susceptibility values of the bilateral putamen were significantly negatively correlated with MoCA scale score(left putamen:rs=-0.316,P=0.015;right putamen:rs=-0.316,P=0.014).Conclusion Abnormal iron metabolism occurs in gray matter nuclei of CSVD patients,and iron deposition in the putamen correlate with cognitive dysfunction.

OBJECTIVETo evaluate the outcome after endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAA) in single center.

METHODSA total of 711 AAA patients treated by EVAR in Department of Vascular Surgery, People's Liberation Army General Hospital and met the inclusion criteria from January 2004 to June 2014 were followed-up and analyzed. There were 612 male and 99 female patients, with a mean age of (69±13) years in this study group. The primary outcome of the study was all-cause mortality, secondary outcome included procedural data, intervention-related morbidity and secondary therapeutic procedures. The endpoint was death. Kaplan-Meier survival analysis were used to analyze long-term survival and cumulative probability of intervention related morbidity. Cox proportional hazards regression was used to analyze factors influenced the survival. Multivariable analysis were adjusted for covariates.

RESULTSThere were 74.8% of total patients followed up. The longest follow-up period was 10.4 years (mean 3.8 years). For the primary outcome of all-cause mortality, 140 deaths occurred. Intervention related morbidity was 9.3%, secondary therapeutic procedures was 5.3%.The Kaplan-Meier survival curve showed that cumulative survival is 78% (95% CI: 74% to 82%) in 5 years, 67% (95% CI: 61% to 74%) in 10 years and the cumulative probability of intervention related morbidity is 10.5% (95% CI: 7.3% to 13.7%) in 5 years, 19.3% (95% CI: 11.9% to 26.0%) in 10 years. Cox proportional hazards regression showed that age>75 years, American Society of Anesthesiologists classification III or IV, smoking, diabetes significantly increase the risk of long-term all-cause mortality, while hypertension significantly decreases the risk.

CONCLUSIONSLong-term outcome after EVAR of AAA in the study is similar to those advanced studies.The management of risk factors would improve the prognosis of these patients.

Objective : To evaluate the clinical effects of resin infiltration in treating molar-incisor hypomineralization. Methods : Twelve patients (36 teeth) with mild molar-incisor mineralization imperfecta who met the inclusion criteria were selected and treated with penetrating resin. Before treatment (T0), at the one-week follow-up (T1) and at the six-month follow-up (T2), a Crystaleye spectrophotometer was used to take photos, and the color differences (ΔE) between the lesion area and the surrounding normal enamel area at different times were calculated and analyzed. The area of the lesion and the total area of the labial surface of affected teeth were calculated using Adobe Photoshop CS3 software. The corresponding area ratio (R) and treatment efficiency (SR) were obtained. The R value was used to judge the effectiveness of resin penetration in the treatment of molar and incisor mineralization imperfecta and to evaluate its aesthetic effect. The results were analyzed by repeated measures one-way ANOVA. Results: The color difference of the lesion area vs sound adjacent enamel (ΔE) decreased significantly, and that of the lesion area decreased significantly after resin infiltration (P < 0.001). The success rate was approximately 86.02%, which means that the esthetic effect of resin infiltration in treating molar-incisor hypomineralization was remarkable. No important adverse events or side effects were observed. Conclusion The aesthetic effect of resin infiltration in the treatment of mild molar and incisor hypomineralization is good. This method is recommended for clinical use.
