Comparison of postoperative data and survival in patients with and without rupture in infra-abdominal aortic aneurysms: 23 years experience

Abstract

Infrarenal abdominal aortic aneurysms are responsible for high rates of rupture-associated morbidity and  mortality  and  can  be  treated  by  open  or  endovascular  surgery. We  compared  the  postoperative data  and  vital  functions  of  the  patients  who  had  undergone open  surgery  for  ruptured  and  non-ruptured infra-renal abdominal aortic aneurysms.Between  January  1996  and  March  2019,  84  patients  (62  males,  22  females)  underwent  open  surgical repair  because  of  infrarenal  abdominal  aortic  aneurysm  in  2  separate  hospitals  in  our  region.  The mean age of our patients was 71.5 ± 6.4 years (range 48-81 years). The patients were divided into two groups. Group I patients were composed of 45 patients and these patients were taken under elective conditions before the rupture occurred. The number of patients in Group II was 39 and these patients were operated after rupture. Group II patients underwent surgical treatment in emergency conditions and  in  an  unstable  hemodynamic  state.  In  Group  II  patients,  the  duration  of  intensive  care  unit  and hospitalization was  higher than Group I. In addition, hospital  costs  were higher in Group II patients. 26  patients  (30.9%) in  Group  II and  5  patients  (5.9%) in  Group  I died  in  the  early  and  postoperative period.According to this retrospective study, operative repair before rupture in infra-renal abdominal aortic aneurysms   decreases   morbidity   and   mortality   rates,statistically.   Therefore,   patients   who   are diagnosed with infra-renal abdominal aortic aneurysm and do not reach the surgical conditions should be  followed  up  as  closely  as  possible  and  should  be  operated  before  rupture  when  the  surgical indication is established.
