Comparative Study On The Effects Of Endovascular Abdominal Aortic Aneurysm Repair And Conventional Surgery On The Patients With Abdonominal Aortic Aneurysms

Objective: to compare the renal function after the endovascular therapy andtraditional laparotomy for abdominal aortic aneurysm, and to assess the perioperativeindicators compare, which would provide the basis on the selection of clinicalapplication.Methods: Clinical data from patients with abdominal aortic aneurysm who received theendovascular therapy and traditional laparotomy from January2007to March2012wereretrospectively analyzed in Affiliated Hospital of Qinghai University. There were atotal of35cases. Cases treated by endovascular therapy and traditional laparotomywere15,20respectively. The cases in two groups were compared by:(1) preoperativegeneral circumstances, such as gender, age, tumor diameter, iliac artery invasion,and complication;(2) the effects of renal function influenced by two therapy;(3)the blood loss in operation, the blood infusion in operation, the operation time, theduration of ICU, the duration of fasting, the length of hospital stay;(4) twoperioperative complication rate and survival rate.Result:1. There were not statistical significance between two groups of preoperativecondition (P>0.05).2. The serum creatinine and blood urea nitrogen before and afterthe operation were not statistically significant in endovascular groups (P>0.05),while the two indicators of the laparotomy group were obviously elevated (P <0.05).3.The intraoperative blood loss, blood infusion, operation time, postoperativeobservation time in ICU, nutritional support time and hospital stay in endovasculargroup were less than aparotomy group (P <0.05).4. The incidence of gastrointestinaldisorders in endovascular group was less than that of the laparotomy group (P <0.05),other complication rate of two groups have no statistical significance (P>0.05);two groups of perioperative survival rates were100%, the difference was notstatistically significant (P>0.05).Conclusion: The endovascular therapy for abdominal aortic aneurysm, to compared with traditional laparotomy, operation, is a relatively safe treatment with less lesion,less influence on renal function, faster postoperative recovery, the lowerpostoperative complication rate; and more suitabllity for elder age and people withmore complications. Nevertheless, traditional laparotomy plays an irreplaceable partfor AAA patients who has the operational indications but being unable to perform theendovascular therapy.
