Purpose: To evaluate the main factors of the 30 days mortality rate of patients operated on for abdominal aortic aneurysm rupture (RAAA.
Patients and method: Univariate and multivariate analysis of various factors associated with RAAA was performed in a group of 73 patients operated on for RAAA between 1996-2001.
Results: The 30 days mortality rate was 35.6 %. The main factors of mortality were: misdiagnosis, cardio- pulmonary-cerebral resuscitation (CPCR) on admission, configuration of RAAA, number of blood transfusions, hypotension on admission (p < 0.0001) and duration of operation, type of reconstruction and hypertension in anamnesis (p < 0.01). Important factors (p < 0.05) of postoperative mortality were also low haemoglobin level on admission, abdominal aortic aneurysm (AAA) diameter and ischaemic heart disease in anamnesis. The probability of patient's death is the highest (p < 0.003), if factors like CPCR, number of blood transfusions and aneurysm diameter are combined (multivariate analysis, stepwise method).
Conclusion: The early detection and surgical or endovascular elective treatment of AAA, the regular dispensation of patients with small AAA especially in hypertonics, the correct diagnosis of RAAA without time delay are the best tools for patients survival. The patient's chance for survival increases with highly trained prehospital resuscitation system and experienced team of vascular surgeons and anesthesiologists.
