INTRODUCTION: The inferior phrenic artery is a paired artery with a variable origin and course, primarily supplying the diaphragm, but also the suprarenal glands, inferior vena cava, stomach, and oesophagus. The aim of this study is to investigate the origin and course of the inferior phrenic arteries on multidetector computed tomography and angiography. MATERIALS AND METHODS: The anatomy of the inferior phrenic artery was analysed on 2449 multidetector computed tomography scans. Three-dimensional reconstructions were made of the main variations. Additionally, the course and branching pattern of the inferior phrenic artery were descriptively analysed in a cohort of 28 angiograms. RESULTS: In 565 (23.1%) cases the inferior phrenic arteries arose as a common trunk and in 1884 (76.9%) cases as individual vessels. The most common origins of a common trunk were the coeliac trunk (n=303; 53.6%) and abdominal aorta (n=255; 45.1%). The most common origins of the right inferior phrenic artery were the coeliac trunk (n=965; 51.2%), abdominal aorta (n=562; 29.8%) and renal arteries (n=214; 11.4%). The most common origins of the left inferior phrenic artery were the coeliac trunk (n=1293; 68.6%) and abdominal aorta (n=403; 21.4%). CONCLUSION: The inferior phrenic artery has a very variable anatomy. The most common origins of the inferior phrenic artery are the coeliac trunk and its branches, the abdominal aorta, and the renal arteries.

AIM: Ankle brachial index (ABI) is a diagnostic tool for peripheral arterial disease (PAD) and a cardiovascular risk stratification tool. Despite this evidence and guidelines recommending its use in everyday practice, ABI is not widely used. Automatic ABI measurement may lower the barrier to incorporate ABI measurement into everyday practice. The aim of this study was to validate a novel automatic oscillometric ABI device (BOSO ABI) against a gold standard-Doppler device in an epidemiological setting. METHODS: In 839 patients from the Czech post-MONICA study (a randomly selected representative population sample aged over 25 years), mean age 54.3±13.8 years (47% of men), ABI measurement was performed using the BOSO ABI device and a handheld Doppler device in a random fashion. The two techniques were carried out by different investigators each blinded to the findings of the other. Analyses were conducted as proposed by Bland and Altman. RESULTS: The mean ABI difference between the two methods was 0.1±0.11, with 95% limits of agreement ranging from -0.11 to 0.30. The difference between Doppler and oscillometric ABI increased significantly with increasing mean ABI (r=0.29; P<0.001). When considering Doppler the gold standard, automated oscillometric measurement had a 76.9% sensitivity, 97.9% specificity, and 37% positive and 99.6% negative predictive values in diagnosing ABI <0.9. CONCLUSION: The BOSO ABI device cannot be used interchangeably for standard Doppler ABI measurement in diagnosing PAD. However, its high negative predictive value allows using it as a screening tool for PAD.

BACKGROUND: Ankle brachial index (ABI) has been increasingly used in general practice to identify individuals with low ABI at high cardiovascular risk. However, there has been no consensus on the clinical significance of high ABI. The aim of our study was to compare aortic stiffness as a marker of cardiovascular risk in individuals with low (<1.0), normal (1.0-1.4), and high ABI (>1.4). METHODS: A total of 911 individuals from the Czech post-MONICA study (a randomly selected 1% representative population sample, aged 54 ± 13.5 years, 47% of men) were examined. ABI was measured using a handheld Doppler and aortic pulse wave velocity (aPWV) using the Sphygmocor device. RESULTS: Of the 911 individuals, 28 (3.1%) had low ABI and 23 (2.5%) high ABI. There was a U-shaped association between aPWV and ABI. aPWV was significantly higher in individuals with low and high ABI compared with the normal ABI group (11.1 ± 2.8, 8.3 ± 2.3, p < 0.001; 10.8 ± 2.5, 8.3 ± 2.3 m/s, p < 0.001, respectively). In a model adjusted for age, sex, systolic, diastolic, mean blood pressure and examiner, aPWV remained increased in both extreme ABI groups compared with the normal ABI group. In logistic regression analysis, aPWV together with glucose level, male sex, and a history of deep venous thrombosis were independent predictors of high ABI, while cholesterol was not. CONCLUSION: This is the first study showing increased aortic stiffness in individuals with high ABI, presumably responsible for increased left ventricular mass described previously in this group. These findings suggest increased cardiovascular risk of high ABI individuals.
