Abstract:
Objective To investigate the effect of covered stent on the treatment of Stanford type B aortic dissection and its effect on cardiopulmonary function. Methods From June 2014 to December 2015, sixty-four AD patients treated in our hospital were selected and were divided into the control group(30 cases) and the observation group ( 32 cases) . The control group was treated with conservative treatment while the observation group was treated with covered stent. After treatment,two groups of patients were followed up for at least 24 months to understand the recovery status after treatment and evaluate the effect. . Results The time of hospitalization of the observation group ((26. 10±8. 14) d) was shorter than that of the control group ((33. 89 ±8. 32) d) (t＝4. 963,P＜0. 05),and there was no statistically significant difference in the mortality and complication rate in 30d after operation between the two groups (χ2＝1. 084,0. 015,P＞0. 05); at 24 months after discharge,the survival rate (93. 75%(30/32)),standard rate of blood pressure 93. 75 (30/32) and treatment compliance rate(90. 63 (29/32)) of the observation group were higher than those of the control group (53.33%(16/30); 60.00(18/32);73.33(22/30)) (χ2 ＝ 13.210、10.088、4.771,P＜0.05) . After treatment,the cardiac output((4. 99±0. 53) L/min) and left ventricular ejection fraction((51. 88±3. 64)%) of the observation group were higher than those of the control group((4. 13±0. 13) L/min,(46. 30 ±9. 63)%). The end systolic diameter of left ventricle (( 55. 75 ± 2. 11) mm) and left ventricular end diastolic diameter ((57. 80± 3. 53) mm) of the observation group were less than those of the control group (( 65. 77 ± 2. 21), (64. 54±2. 67) mm). The differences between the two groups were statistically significant(t＝8. 643、3. 054、8. 436、18. 263,P＜0. 05). Conclusion Covered stent is safe and effective in the treatment of Stanford type B aortic dissection.
