AIM: The main goal of this final work is to present the process of health care, i.e. determination of patient needs, planning and implementation of interventions as well as evaluation of what has been done, in patients before and after endovascular repair of abdominal aortic aneurysm. DISCUSSION: Patient N.N. was admitted as a regular admission to the Department of Vascular Surgery under the diagnosis of abdominal aortic aneurysm. Endovascular repair of abdominal aortic aneurysm – EVAR is indicated. After pre-operative preparation and treatment, the patient was operated on in the Angio room. He was transferred to the Intensive Care Unit and then to the Surgical Intensive Care Department and finally, 48 hours later, returned to the ward. Through the presentation of the case, the current problems of the patient were identified, and nursing medical diagnoses were processed with the aim of meeting the basic human needs of the patient. CONCLUSION: An abdominal aortic aneurysm is a bulge in the abdominal part of the aorta and a potentially life-threatening condition due to the risk of rupture and severe internal bleeding. Along with the medical team, an important link in the care of patients before and after surgery is the nurse who, through the process of health care, identifies and solves individual physical, psychological and social problems of the patient. Every step in the patient's health care process is aimed at achieving the greatest possible independence of the patient.
