Endovascular type B aorta dissection repair: A comparative study of early outcomes between total percutaneous technique and surgical femoral cut-down

Objective To assess the difference in endovascular type B aorta dissection repair between total percutaneous technique（TPT） and surgical femoral cut-down（SFC）. Methods Eighty-one patients with uncomplicated type B aorta dissection admitted to our hospital from January 2009 to August 2011 for endovascular repair were included in this study.The patients were divided into TPT treatment group（n=26） and SFC treatment group（n=55）.Their operation time,intra-operative blood loss,contrast media dosage,complications and hospital stay time were compared. Results No significant difference was observed in the age,gender,acute dissection rate and incidence of hypertension between the two groups（P＞0.05）.However,the contrast media dosage was significantly lower and the operation time was significantly shorter in TPT treatment group than in SFC treatment group（P＜0.05）. Conclusion TPT can effectively reduce the contrast media dosage and operation time of patients with uncomplicated type B aorta dissection.However,its long-term effect needs to be further observed.
