Khaja, Piotr Obara, Stephen P. Reis, Kanupriya Vijay, Karin E. DillAbstractAbdominal aortic aneurysm (AAA) is defined as aneurysmal dilation of the abdominal aorta to 3 cm or greater. A high degree of morbidity and mortality is associated with AAA rupture, and imaging surveillance plays an essential role in mitigating the risk of rupture. Aneurysm size and growth rate are factors associated with the risk of rupture, thus surveillance imaging studies must be accurate and reproducible to characterize aneurysm size. Ultrasound, CT angiography, and MR angiography provide an accurate and reproducible assessment of size, while radiographs and aortography provide limited evaluation.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development...

Numerous studies have shown a paradoxical protective effect of diabetes on the development and progression of abdominal aortic aneurysm (AAA). The aim of this study was to investigate whether the protective role of diabetes on AAA extends to rupture, given the presence of an AAA.
AbstractRupture with fistulization of an abdominal aortic aneurysm with the vena cava is a rare complication and typically presents with congestive cardiac failure. Embolization of a thrombus from the aneurysm into the vena cava can however present in the absence of failure symptoms which can make it difficult to diagnose clinically without cross sectional imaging.
Authors: Lareyre F, Carlier M, Raffort J Abstract The presence of accessory renal artery is a frequent anatomic variation that can challenge abdominal aortic aneurysm (AAA) repair. Here, we show an image of an abdominal aortic aneurysm extended to multiple accessory renal arteries in a patient known for an end-stage renal failure. This case raises the questions of the criteria that should be taken in consideration for an optimal management of accessory renal artery during AAA repair.

The objective of this study was to report the 5-year outcomes of the Food and Drug Administration investigational device exemption clinical trial of endovascular aneurysm repair (EVAR) with the Ovation stent graft (Endologix, Irvine, Calif) for elective treatment of abdominal aortic aneurysm (AAA).
Posthospital syndrome (PHS) is an acquired, transient period of health vulnerability after a hospital admission for acute illness. It is characterized by physiologic deconditioning secondary to stressors from disruption in circadian rhythm, depletion of nutritional and physiologic reserve as well as the pain and discomfort associated with hospitalization. PHS is reported as an independent risk factor for readmission and adverse postoperative outcomes. The aim of this study is to investigate whether preoperative hospitalization affects outcomes of elective endovascular repair of abdominal aortic aneurysm (EVAR).

Popliteal artery aneurysm (PAA) carries a risk of sudden thromboembolism resulting in acute limb ischaemia (ALI). Since 2010, all 65 years old men in Region Sk åne are invited for abdominal aortic aneurysm (AAA) screening, and subsequently for PAA if AAA is detected.
The aorta is a main blood vessel in the chest and abdomen. An abdominal aortic aneurysm (AAA) is an abnormal enlargement of the aorta in the abdomen; it is often asymptomatic, meaning that it causes no symptoms. Monitoring the size and growth of the aneurysm is important because it is often fatal if the aneurysm ruptures. This is more likely in individuals with AAA that grows more than 2 mm per year. Treatment should be considered when an individual without symptoms has an AAA larger than 5.4 cm in men and 4.9 cm in women.
