Introduction: The term ‘aneurysm’ is derived from the Greek word aneurysma, meaning dilatation, or widening. The International Society for Cardiovascular Surgery/Society for Vascular Surgery states that an abdominal aortic aneurysm is any focal dilation of the aorta leading to a diameter of at least 50% larger than normal. The normal aorta diameter ranges from 17 to 24mm and is dependent on various factors such as such as age, gender, and body habitus. AAA occurs when the aortic diameter is more than 30 mm in size. An unruptured aortic aneurysms are incidentally detected and come with chronic vague complaints like back pain, abdomen pain, palpitations, dyspnoea on exertion etc. A ruptured AAA is an absolute emergency and require immediate surgical intervention.
Signs, symptoms, and Diagnosis: This is a case report of a 53-year-old female who presented with complaints of on and off chest discomfort associated with palpitations and dyspnoea on exertion for the past 2 years. CT aortography revealed infrarenal abdominal aortic aneurysm extending to the iliac arteries with maximum diameter of 67 mm. This review will mainly focus on the instructive significance for anaesthesia management, especially during clamping and unclamping of major vessels during abdominal aortic aneurysm resection surgery.
