Our anaesthetic experiences in endovascular aortic stent graft surgery

Abstract

Objective: Thoracic and thoraco-abdominal aortic aneurysms and dissections have highest mortality and morbidity causing pathologies in cardiovascular surgery. Co-existing diseases and age significantly increase risk of anesthesia and mortality rate in treatment of these patients. Endovascular techniques are used increasingly due to minimally invasive approach, decreased anesthesia risk during implementation, reduced length of hospital stay, and low mortality and mobidity rates. The aim of this investigation was to report our anesthetic experiences in endovascular techniques performed at TOBB University of Economics and Technology Hospital. Material and Methods: We evaluated 70 (58 male, 12 female) consecutive symptomatic patients with thoracic and abdominal aortic pathologies who underwent endovascular stent graft surgery with either general or sedation and local anesthesia between January 2012-June 2017, at our center. Results: The number of patients having endovascular stent graft surgery was 70. Of all the cases 58 (82.9%) male and 12 (17.1%) female patients were included in our study. 40 of our cases were in ASA III risk group. Comparison of demographic variables, ASA status, co-existing diseases were not different between groups. 24 (86%) of thoracic endovascular aortic repair (TEVAR) patients received general anesthesia, 33 patients who had been administered with abdominal endovascular aortic repair (EVAR) were given general and 13 were given sedation and local anesthesia. While 28 of the patients administered with EVAR had hypertension and also 20 of the patients administered with TEVAR had hypertension. No significant differences were found in blood and blood product transfusions, preoperative and postoperative hemoglobin, hematocrit, urea and creatinine values between two groups. Conclusion: In EVAR and TEVAR applications general anesthesia, sedation accompanied by local anesthesia can be successfully administered depending on the patient's status and the location of the procedure. © Copyright 2017 by Türkiye Klinikleri.
