11th EORNA Congress Valencia, Spain | 16 - 18 May 2024 ePosters 66 365 Endovascular treatment of pararenal aortic aneurysm ATHANASIA KAVGA1 1, Andreas Misisian1 1Athens Medical Center, Marousi, Greece Background: Aorta is the largest vessel of the human body; it arises from the heart, passes through the thoracic cavity and ends in the abdomen where it divides into the two iliac arteries. The part of the aorta located inside the abdomen is called the abdominal aorta and supplies the abdominal organs and lower extremities with blood. Abdominal aortic aneurysm (AAA) is defined as the dilatation of the abdominal aorta to a diameter that is more than 50% increased compared to the normal diameter of the vessel. Seventy-five percent of the aneurysms are asymptomatic and firstly manifested when they rupture. Therefore, aneurysms are commonly diagnosed incidentally during scans performed for other reasons (e.g. ultrasound or CT scans for urology or general surgery issues). Abdominal aortic aneurysms that include the renal arteries are called pararenal aneurysms. Objectives: The addition of fenestrations and scallops to the classic endografts results in blood flow preservation to the visceral branches of the abdominal aorta. Partial graft deployment, the markers of the graft and high- resolution intraoperative angiogram along with the use of guidewires allow the appropriate manipulations in order to align the fenestrations within the orifices of the target vessels. Methods: Treatment - surgical repair - is necessary when the AAA diameter exceeds 5cm or an increase of its diameter of 0,5 cm within 6 months or 1 cm within 1 years is observed. Symptomatic and saccular aneurysms also require surgical treatment. Results: Placement of covered bridging stent-graft into the target-vessels secures and stabilizes the graft and allows blood flow to the kidneys, the superior mesenteric artery and the celiac arteries. Conclusion Contemporary fenestrated and branched endografts make endovascular repair of pararenal and juxtarenal aneurysms with hostile anatomy feasible; this option was not available a few years ago 367 Evaluation of anxiety and stress levels on preoperative waiting time with DASS Scale between day care surgery clinic versus long-term hospitalization; Pilot Study Maria Kapritsou1, Vasiliki Papanikolaou2, Theodoros Sergentanis2, Eleni Kornarou2 1Hellenic Anticancer Institute “Saint Savvas”, Surgical Sector, Athens, Greece, 2Dept. of Public Health Policy, University of West Attica Background: The anxiety and stress levels of patients, who are scheduled for elective procedures, cause great concern to many health professionals. In fact, the effects of this problem could be seen in all aspects of patient’s hospitalization, causing higher morbidity after surgery. Many factors influence preoperative stress levels, such as the waiting time before surgery. Objectives: The aim of this study was the impact of the waiting time, on preoperative levels of anxiety and stress of patients admitted for long-term care (LONG) in relation to these levels of patients admitted to day care center (DCC) for surgery, with ultimate goal the implementation of Quality Health Management. Methods: It was a prospective cross- sectional clinical study which was conducted in 2020 with a sample of 176 patients who had undergone elective surgery. In DCC group (n=88), patients were hospitalized in DCC, while in group LONG (n=88) patients were hospitalized in LONG care oncological hospital. Demographic and clinical data were collected and patients were assessed by the Depression, Anxiety and Stress Scale (D.A.S.) scale, preoperatively. Statistical analysis was performed with SPSS 25.0, at a significance level α = 0.05. Results: D.A.S. scale’s Cronbach’s α was 0.923. There was no statistically significant difference between the groups for age, but there were significant differences in the waiting time (months) before surgery and the waiting time (days) before surgery after the admission to the hospital (t=-0.719, p=0.473, U=2884, p=0.002 and U=0, p<0.001, respectively). In group LONG, patients were waiting at least three days before surgery. Evaluation of stress levels showed statistical difference between the two groups (p=0.05). Conclusion: Prolonged preoperative waiting time has shown to have a negative impact on patient’s stress levels. Therefore, the goal of health administrators should be the provision of individualized information to patients, through the improvement of the elective surgery process.
