“…Among these three definitions, the SVS/ISCVS one is the most sensitive, detecting the largest number of aneurysms; however, it is necessary to study the natural history and effect of interventions. 18 The reported mean diameter of the normal infrarenal abdominal aorta ranges between 14.1 and 23.9 mm in males 4,15,[19][20][21][22][23] and between 11.9 and 21.6 mm in females. [19][20][21][22] Using the SVS/ISCVS criteria, the upper limit of 30 mm is appropriate, 18 as most screening studies define an AAA by a maximum infrarenal diameter of more than 30 mm.…”

Screening for abdominal aortic aneurysms during a basic medical checkup in residents of a Japanese rural community

To determine the prevalence of abdominal aortic aneurysms (AAA) and the size distribution of the abdominal aortic diameter in the Japanese population, 1,591 residents of a farming community were screened by ultrasonography during the annual basic medical checkup arranged by the town. The mean diameter of the abdominal aorta was 17.2 +/- 2.2mm and four AAAs were found (0.3%), all in men aged 60 years or older, three of whom were hypertensive. The mean diameter of the common iliac artery was 10.2 +/- 5.1mm and five iliac arterial aneurysms were found (0.3%). One man had both aortic and iliac arterial aneurysms. The iliac arterial aneurysms were also found in men, four of whom were aged 60 years or older and had a smoking habit. We were able to keep the cost of screening low by combining the program with an annual basic medical checkup. These findings indicate that it is important to examine the iliac artery as well as the abdominal aorta because the incidence of aneurysm is similar in both. Screening for AAAs using ultrasonography is accurate enough to detect them before rupture, and can be effectively performed in men aged 60 years or older during their annual basic medical checkup.

“…Prevalence varied fourfold depending on the definition used. This complicated efforts to assess risk and interventions, and created uncertainty about who should be offered a high-risk operation 3 .…”

promise was doubtful and its validity unlikely to have been vetted. Predatory journals are a global threat. They accept articles for publication-along with authors' fees-without performing promised quality checks for issues such as plagiarism or ethical approval. Naive readers are not the only victims. Many researchers have been duped into submitting to predatory journals, in which their work can be overlooked. One study that focused on 46,000 researchers based in Italy found that about 5% of them published in such outlets 1. A separate analysis suggests predatory publishers collect millions of dollars in publication fees that are ultimately paid out by funders such as the US National Institutes of Health (NIH) 2. One barrier to combating predatory publishing is, in our view, the lack of an agreed definition. By analogy, consider the historical criteria for deciding whether an abnormal bulge in the aorta, the largest artery in the body, could be deemed an aneurysm-a dangerous W hen 'Jane' turned to alternative medicine, she had already exhausted radiotherapy, chemotherapy and other standard treatments for breast cancer. Her alternative-medicine practitioner shared an article about a therapy involving vitamin infusions. To her and her practitioner, it seemed to be authentic grounds for hope. But when Jane showed the article to her son-in-law (one of the authors of this Comment), he realized it came from a predatory journal-meaning its Leading scholars and publishers from ten countries have agreed a definition of predatory publishing that can protect scholarship. It took 12 hours of discussion, 18 questions and 3 rounds to reach.

“…For the purposes of our study we took note of recent work by Moher et al, who using the criteria ofthe Society for Vascular Surgery and the International Society for Cardiovascular Surgery determined the mean infrarenal aortic diameter (20 mm) for 141 unaffected men (maximum infrarenal aorta <30 mm) and then multiplied this by 1'5. 10 We have used Moher's definition of an AAA as an Distribution of aorric diameter.…”

Opportunistic Screening for Abdominal Aortic Aneurysm

et al. 1994

Opportunistic screening for AAA in men undergoing clinically indicated abdominal ultrasonography is easy, productive, without discernible cost, and discloses a prevalence of AAA comparable with that of population screening programmes. Routine opportunistic measurement of aortic diameter during abdominal ultrasonography in the at risk group would allow 12-15% of men aged 65-74 to be screened for AAA within five years without the need for any additional resources.
