Background: In this study, we analyzed epidemiologic characteristics and morphologic differences between Asian and European population in patients with abdominal aorta aneurysm (AAA). Method: We conducted concomitant study in Japan and Europe , in 31 Asian patients (AP) with AAA and 130 control subjects of the same population, and in 30 European patients with AAA and 126 control subjects (EP). We observed various demographic and anthropologic parameters. Aortography was performed in all patients at the same type of CT-scanners using the same examination protocol and postprocessing. For data analysis, various statistical models were used. Results: There are statistically significant differences in multiple epidemiologic and morphologic findings in AAA patients, as well as in comparison with controls in both groups. This is most distinct in terms of anthropologic characteristics and number of risk-factors, and in terms of morphologic findings, in the length of neck of the aneurysm, transverse diameter of abdominal aorta (AA) and common iliac artery (c.i.a), and volumes of c.i.a. We obtained paradoxical results considering diabetes mellitus, which presented itself as a protective factor for AAA. Conclusion: Demographic-epidemiologic analysis accompanied with morphologic measurements using modern imaging modalities enables obtaining new information on pathology of AAA in different races. There are differences in number of risk-factors, and in terms of morphologic findings, in the length neck, angle of the aneurysm, transverse diameters of abdominal aorta (AA) and in the length of common iliac artery (c.i.a), and volume of c.i.a.

AbstractIntroduction:Exsanguination from a femoral artery wound can occur in sec-onds and may be encountered more often due to increased use of body armor. Some military physicians teach compression of the distal abdominal aorta (Abdominal Aorta) with a knee or a fist as a temporizing measure.Objective:The objective of this study was to evaluate if complete collapse of the Abdominal Aorta was feasible and with what weight it occurs.Methods:This was a prospective, interventional study at a Level-I, academ-ic, urban, emergency department with an annual census of 80,000 patients. Written, informed consent was obtained from nine male volunteers after Institutional Research Board approval. Any patient who presented with abdominal pain or had undergone previous abdominal surgery was excluded from the study. Subjects were placed supine on the floor to simulate an injured soldier. Various dumbbells of increasing weight were placed over the distal Abdominal Aorta, and pulsed-wave Doppler measurements were taken at the right common femoral artery (CFA). Dumbbells were placed on top of a tightly bundled towel roughly the surface area of an adult knee. Flow measurements at the CFA were taken at increments of 20 pounds. This was repeated with weight over the proximal right artery iliac and distal right iliac artery to eval- uate alternate sites. Descriptive statistics were utilized to evaluate the data.Results:The mean velocity through the CFA was 75.8 cm/ sec at 0 pounds. Compression of the Abdominal Aorta ranging 80 to 140 pounds resulted in no flow in the CFA. A steady decrease in mean flow velocity was seen starting with 20 pounds. Flow velocity decreased more rapidly with compression of the prox- imal right iliac artery, and stopped in all nine volunteers by 120 pounds of pressure. For all nine volunteers, up to 80 pounds of pressure over the distal iliac artery failed to decrease CFA flow velocity, and no subject was able to tolerate more weight at that location.Conclusion:Flow to the CFA can be stopped completely with pressure over the distal Abdominal Aorta or proximal iliac artery in catastrophic wounds. Compression over the proximal iliac artery worked best, but a first responder still may need to apply upward of 120 pounds of pressure to stop exsanguination.

Maxadilan is a peptide from the salivary gland of the sand fly Lutzomyia longipalpis, a vector for leishmaniasis. Cutaneous injection of femtomolar quantities of maxadilan produces long-lasting erythema, making it the most potent vasodilator known. Isolated rabbit thoracic and abdominal aorta, carotid artery, and iliac artery demonstrated dose-dependent arterial relaxation in response to maxadilan with a mean effective concentration (EC50) of 2.7 +/- 1.5, 2.1 +/- 0.5, 2.6 +/- 0.4, and 1.9 +/- 0.5 nM, respectively. Maxadilan proved to be at least sevenfold more potent than nitroglycerin in each arterial bed (EC50 = 25 +/- 12, 32 +/- 9, 37 +/- 10, and 22 +/- 13 nM, respectively; P < 0.05 for each vs. maxadilan). Arterial relaxation to maxadilan was independent of endothelium and was equipotent in the thoracic and abdominal aorta, carotid artery, and iliac artery. Arterial relaxation to maxadilan was not inhibited by K(+)-channel antagonists, methylene blue, quinacrine, or ouabain. Maxadilan-mediated arterial relaxation was found to be adenosine 3',5'-cyclic monophosphate (cAMP) dependent, as it was potentiated by the phosphodiesterase inhibitors 3-isobutyl-1-methylxanthine and theophylline, and it was inhibited by the protein kinase A inhibitor H-89. Consistent with this observation, incubation of thoracic aorta with maxadilan (0.1 microM) produced a time-dependent increase in arterial cAMP content coincident with arterial relaxation. Using rabbit aortic smooth muscle cells, we also observed a time-dependent reduction in intracellular calcium in response to maxadilan. Thus these data indicate that maxadilan, a peptide from the sand fly salivary gland, is a potent vasodilator that reduces intracellular calcium through a cAMP-dependent mechanism.

Abstract Objective: Diameter is currently the only screening and diagnostic criterion for asymptomatic aneurysms. Therefore, aortic and lower-extremity arterial diameter has diagnostic, therapeutic, and prognostic importance. We aimed to determine aortic and lower-extremity arterial reference diameters in a general population and compare them according to age, sex, and other characteristics.Methods: We evaluated consecutive 3,692 patients who underwent computed tomography as part of a general health checkup from 2015–2019 in a single tertiary center. Aortic and lower-extremity arterial diameters and the most important factor related to arterial diameters were evaluated.Results: The mean diameter of the abdominal aorta was 17.490 ± 2.110 mm, while that of the common iliac artery was 10.851 ± 1.689 mm. The mean diameter of the abdominal aorta was 18.377 ± 1.766 mm in men and 15.884 ± 1.694 mm in women. Significant intersex differences were observed for all mean diameters and lengths. Multilinear regression analysis showed that age, sex, and body surface area impacted mean diameters of all measured sites except aorta and common iliac artery length. Between male and female patients matched for body surface area, there were significant intersex differences for all measured sites, except for common iliac artery length.Conclusions: The mean diameter of the abdominal aorta in this healthy cohort was 17.490 ± 2.110 mm overall, 18.377 ± 1.766 mm in men, and 15.884 ± 1.694 mm in women. Arterial diameter increased with male sex, older age, and increased body surface area, and aortic diameters were larger in men than in women with the same body surface area.
