Aim: The aim of our study was to estimate frequency of MINS and others complications after endovascular aorta repair because of AAA in different age groups.

Introduction: Nowadays, endovascular aneurysm repair (EVAR) is the most common technique for repair of abdominal aorta aneurysm (AAA). This procedure involves less complications than open surgery, nevertheless they still occurs.

Methods: The study group consisted of 143 patients (85.3% men), aged 76.8±7.7 with AAA who had endovascular aneurysm repair between January 2015 and May 2017 in the Department of Vascular Surgery and Angiology. Patients were divided into two groups depending on age: group I ≤75 years (60 patients, aged 69.3±4.5), group II >75yrs (83 patients, aged 82.2±4.2). We considered coexistent diseases, some laboratory tests and Revised Cardiac Risk Index for Pre-Operative Risk (Lee index). Statistical analysis was performed with U Mann-Whitney and Chi2 tests.

Results: The study groups were comparable regarding the coexistent diseases and preoperative risk. Older patients had higher mean creatine level on admission than younger patients (group I: 103.29±84.10 vs. group II: 118.5±61.9umol/l, p<0.005) and lower eGFR (80.6±27.6 vs. 61.61±21.9 vs. 1.73ml/min/m2, p<0.001). The mean concentration of haemoglobin and amount of white blood cells were also lower in elderly patient (13.19±1.93 vs. 12.9±18.3g/dl, p=0.01; 8.23±2.74 vs. 7.49±2.7×103/μl, p=0.04).

Frequency of some complications such as acute kidney injury, pneumonia, sepsis, stroke or intrahospital mortality were similar in both groups.

However, we observed a statistically significant difference in the frequency of MINS (26.67% vs. 45.78%; p=0.04). Older patients also needed red blood cells concentrate transfusion after surgery more often than younger (6.67% vs. 19.28%; p=0.03).

Conclusion: MINS is the most common complication after EVAR. Age seems to be a significant feature which increases the frequency of MINS in compared groups despite similar coexistent diseases and preoperative risk assessment determined by Lee index.1–3
