ACR Appropriateness Criteria ® Abdominal Aortic Aneurysm Follow-up (Without Repair)

Abdominal 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.

It has been noted that dysregulation of microRNAs (miRNAs) contributes to the formation of abdominal aortic aneurysm (AAA), a vascular disease associated with progressive aortic dilatation and degradation, and pathological infiltration and activation of inflammatory cells, such as macrophages. Our microarray data revealing that miR-144-5p was the top 1 downregulated miRNA in mouse AAA tissues as compared to normal aortas motivated us to explore its role in AAA development.

Authors: Huang D, Song F, Zhou X, Ma H, Chen S, Xie Y, Wang S, Qin T Abstract Arteriovenous fistula (AVF) is a rare complication of the abdominal aortic aneurysm (AAA) with complex clinical features. However, AVF and AAA usually cause no symptoms except when they rupture. This case study demonstrated that ultrasonography was a rapid and non-invasive method for the initial assessment of AAA and AVF. A 65-year-old man was admitted to the intensive care unit with hepatic and renal dysfunction. Physical examination revealed an abdominal vascular murmur and bilateral toe discoloration. Ultrasonic examination revealed an...

Authors: Shi F, He Y, Wang S, Jia F, Ji C, Zhang J, Liu X, Han Y Abstract Abdominal aortic aneurysms (AAA) are life-threatening serious conditions that require effective and quick management. Although it is generally acknowledged that patients with AAA obtain the greatest benefit from endovascular repair (EVAR) compared to open surgical repair (OSR), there are few comparisons between the surgical approaches in Western versus Chinese patients. We aimed to perform a meta-analysis of studies in which EVAR was compared with OSR in the management of abdominal aortic aneurysms. We searched the Western literature through ...

The uncertainty surrounding COVID-19 is making it difficult for public companies to accurately forecast 2020 earnings. Irvine, CA-based Endologix recently joined a growing list of medical device companies that have withdrawn previously-reported financial guidance for the year. The company makes endovascular stent grafts for the treatment of abdominal aortic aneurysms (AAA). AAA is a weakening of the wall of the aorta, the largest artery in the body, resulting in a balloon-like enlargement. Once an AAA develops, it continues to enlarge and, if left untreated, becomes increasingly susceptible to rupture. Endologix said AAA p...

Patients who undergo endovascular aneurysm repair (EVAR) often require reintervention after the index repair. The long-term rate of reintervention and how this has changed with newer device technology are poorly understood. Therefore, we performed a systematic review and meta-analysis of the available literature to determine long-term freedom from reintervention after EVAR and the change in reintervention rates over time.

The few randomized trials comparing endovascular with open surgical repair of ruptured abdominal aortic aneurysm (rAAA) were poorly designed and heavily criticized. The short-term and midterm survival advantages of endovascular repair remain unclear. We sought to compare the two treatment modalities using a propensity-matched analysis in a real-world setting.

AbstractPurposeWe investigated the etiology and impact on outcomes of polycystic kidney disease in patients with abdominal aortic aneurysm.MethodsEight-hundred patients who underwent open (n = 603) or endovascular aortic repair (n = 197) were divided into three groups: no cyst (n = 204), non-polycystic kidney (n = 503), and polycystic kidney (≥ 5 cysts in the bilateral kidneys,n = 93). The characteristics and outcomes were compared among the groups.ResultsIn the polycystic kidney group, the age was increased and the proportions of patients with...
