ABSTRACT
Objective:To investigate the clinical characteristics as well as short-term and long-term prognostic factors of patients with Stanford type B aortic dissection (TBAD) with hypertension.Methods:Patients with TBAD who received thoracic endovascular aortic repair (TEVAR) admitted to Xiangyang Central Hospital from January 2014 to December 2018 were enrolled. The baseline data of patients admitted to the hospital were collected through the case management system, including gender, age, underlying diseases (hypertension, diabetes, coronary heart disease), smoking history, drinking history, duration of pain, vital signs at admission [heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP)], laboratory results [white blood cell count (WBC), platelet count (PLT), neutrophil/lymphocyte ratio (NLR), serum creatinine (SCr), C-reactive protein (CRP), D-dimer, ascending aorta diameter], etc. The clinical characteristics of TBAD patients with hypertension were analyzed. Logistic regression model and Cox proportional risk model were used to analyze the impact of hypertension on the short-term and long-term all-cause deaths after TEVAR in TBAD patients.Results:Among 227 TBAD patients, 160 cases (70.5%) were complicated with hypertension, while 67 cases (29.5%) were not. The average age, the proportion of diabetes and coronary heart disease, and the level of SBP, DBP and SCr at admission of TBAD patients with hypertension were higher than those of TBAD without hypertension [age (years old): 53.1±11.9 vs. 42.8±14.1, combined with diabetes: 8.8% vs. 1.5%, combined with coronary heart disease: 6.3% vs. 0%, SBP (mmHg, 1 mmHg = 0.133 kPa): 147.9±18.1 vs. 136.9±15.2, DBP (mmHg): 93.9±11.9 vs. 89.1±13.8, SCr (μmol/L): 97.8±25.4 vs. 89.8±23.6, all P < 0.05]. The short-term mortality of TBAD with hypertension group was significantly higher than that of TBAD without hypertension group [6.3% (10/160) vs. 0% (0/67), χ2 = 4.386, P = 0.036]. 227 patients with TBAD were followed up for 3-66 months, with a median follow-up time of 25 months. There was no significant difference in long-term mortality between TBAD patients with and without hypertensive during discharge follow-up [13.1% (21/160) vs. 9.0% (6/67), χ2 = 0.784, P = 0.376]. Further multivariate Logistic regression analysis and Cox regression analysis did not indicate that hypertension was an independent risk factor for short-term and long-term death in TBAD patients [odds ratio ( OR) and 95% confidence interval (95% CI) were 13.477 (0.541-330.215), 1.012 (0.990-1.035), both P > 0.05]. Age and HR were independent risk factors for the short-term mortality of TBAD patients [ OR and 95% CI were 15.287 (1.051-226.415), 0.026 (0.002-0.840), both P < 0.05]. Age, PLT and D-dimer were independent risk factors for the long-term mortality of TBAD patients [ OR and 95% CI were 1.808 (1.205-2.711), 0.555 (0.333-0.924), 1.482 (1.035-2.122), respectively, all P < 0.05]. Conclusions:The TBAD patients with hypertension have older age, high rates of diabetes or coronary heart disease. However, hypertension is not an independent risk factor for short-term and long-term mortality in TBAD patients.
ABSTRACT
Objective To investigate the methods and effect of the dual incision lock type golf combined with support plate in the treatment of tibial plateau fracture.Methods 80 cases with comminuted fracture of the tibial plateau were randomly divided into two groups.40 cases in the observation group were given the dual incision lock type golf combined with support plate.and the control group used traditional single incision T-shaped steel treatment.The clinical efficacy was compared between the two groups.Results 80 patients were followed up.Excellent rate of the observation group was 67.5％,which was significantly higher than 45.0％ of the control group.The incidence rate of complication in observation group was 2.5 ％,which was significantly lower than 22.5 ％ in the control group (P ＜ 0.05).The reset extent of patients,healing time,loading time,HSS score of the observation group were significantly better than those of the control group (P ＜ 0.05).Conclusion The dual incision lock type golf combined with support plate in the treatment of tibial plateau fracture has less trauma,reliable fixation,early functional exercise andfewer complications.
