Computed Tomography for the Diagnosis and Management of Abdominal Aortic Aneurysms

Vascular surgery is a relatively new surgical sub-speciality in the UK, with treatment of abdominal aortic aneurysms forming a substantial proportion of the emergency and elective caseload. This article summarises the guidance from the National Institute of Health and Care Excellence and the European Society for Vascular Surgery that outlines the epidemiology, diagnosis and management of abdominal aortic aneurysms. This is important for both vascular and non-vascular trainees to understand because of the critical nature of the disease, which can cause catastrophic haemorrhage, limb loss and mortality. However, if discovered in time, abdominal aortic aneurysms are a very treatable condition.

Infectious abdominal aortic aneurysms often present with abdominal and lower back pain, but prolonged fever may be the only symptom. Infectious abdominal aortic aneurysms initially presenting with meningitis are extremely rare; there are no reports of their successful treatment. Cases withStreptococcus pneumoniaeas the causative bacteria are even rarer with a higher mortality rate than those caused by other bacteria. We present the case of a 65-year-old man with lower limb weakness and back pain. Examination revealed fever and neck stiffness. Cerebrospinal fluid showed leukocytosis and low glucose levels. The patient was diagnosed with meningitis and bacteremia caused byStreptococcus pneumoniaeand treated with antibiotics. Fever, inflammatory response, and neurologic findings showed improvement. However, abdominal computed tomography revealed an aneurysm not present on admission. Antibiotics were continued, and a rifampicin soaked artificial vascular graft was implanted. Tissue cultures showed no bacteria, and histological findings indicated inflammation with high leukocyte levels. There were no postoperative complications or neurologic abnormalities. Physical examination, blood tests, and computed tomography confirmed there was no relapse over the following 13 months. This is the first reported case of survival of a patient with an infectious abdominal aortic aneurysm initially presenting with meningitis caused byStreptococcus pneumoniae.

Local Mechanical Property

Cardiovascular disease concerns any disease which affects the heart or blood vessels. Aneurysms account for a significant portion of these cardiovascular diseases. The most common type of aneurysm is abdominal aortic aneurysm (AAA) which affects up to 5% of the population over the age of 55. AAA is a focal balloon like dilation of the terminal aorta that occurs gradually over a span of years [1]. There are approximately 200,000 patients in the US and 500,000 patients worldwide diagnosed with AAA each year [2]. The incidences of AAA’s has increased largely during the past two decades due in part to the aging demographic, the rise in the number of smokers, the introduction of screening programmes and improved diagnostic tools [3].
