Relations between timing of treatment in stanford B acute aortic dissection vascular repair and prognosis / 中国基层医药

ABSTRACT

Objective To investigate clinical relevance of the acute Stanford B aortic dissection vascular repair time for treatment and prognosis.Methods A retrospective clinical data of our hospital treated 1 10 cases of vascular repair of acute aortic dissection type Stanford B were analyzed according to the onset to treatment time.They were divided into three groups:group A (onset to treatment time of 7 days),group B (onset to treatment time 14) and group C (onset to treatment time than 14 days);the three groups were observed after aortic repair status and prognosis related indicators.Results The true lumen false lumen diameter and maximum diameter ratio in group A was the largest (1.8 ±0.5),which was significantly higher than that of group B and group C (1.3 ±0.3)and (1.3 ± 0.2),the difference was statistically significant (F=7.352,P<0.05).Ratio of preoperative minimum true lumen diameter and the maximum diameter of the false lumen,ratio of postoperative maximum true lumen diameter and the maximum diameter of the false lumen were associated with the onset of the endovascular repair time,showed a negative correlation (r=-0.452,-0.281,all P<0.05).postoperative complication rate of group A was 12.8%,complica-tion rate of group B was 29.5%,complication rate of group C was 33.3%,data of group A was significantly lower than those of group B and group C,the difference were statistically significant (χ2 =4.024,4.721,all P<0.05).group A died three cases,group B had 1 patient died and in group C there was no deaths.Hospital stay and hospital costs of group A were significantly lower than those of group B and group C,the difference werestatistically significant (F=4.125,7.375,all P<0.05).Conclusion As soon as possible to implement acute aortic dissection stanford B aortic vascular repair could better improve outcomes,and reduce the cost of hospitalization and treatment.At the same time, it can reduce the incidence of complications and improve clinical safety.
