The World

The report of the first successful resection of an abdominal aortic aneurysm, carried out in Paris in 1951, greatly influenced surgeons throughout the world who, until then, had regarded such an operation as probably being outside the bounds of surgical removal and vascular reconstruction. I well remember as a young surgeon reading of attempts to control such aneurysms by wrapping them in cellophane, or introducing coils of wire into them to induce thrombosis and I was familiar with having to stand by hopelessly as patients exsanguinated when their aneurysms ruptured.

Forensic Epidemiology

ABSTRACT A case is described in which a 55-year-old Nigerian woman of the Igbo ethnic group died suddenly of a rupture of an atherosclerotic infrarenal aortic aneurysm. Necropsy revealed several features usually associated with this condition, but which occur very rarely in the African Negro. The report of its occurrence in this part of the world may facilitate further research in forensic epidemiology.

Introduction: The objective of this study is to understand the role of neurological factors, specifically those from the perivascular sympathetic nervous system (SNS), on the initiation and development of Abdominal Aortic Aneurysm (AAA). Hypothesis: We hypothesize that the formation of AAA is associated with the loss of perivascular SNS-induced vasoconstriction specific to the aneurysm region. Methods: We developed a rat Abdominal Aortic Denervation (AAD) model, where the infrarenal aorta of Spauge Dawley rats was denervated with surgical removal of nerve fibers and chemical denervation with 10% phenol ( Figure. A ). A sham control group was included where the infrarenal aorta was treated with PBS. The arteries were harvested at 1 month after the surgeries for histological assessment. Results: The denervated aortas exhibited significant thinning of the aortic wall including the media and the adventitia, compared to the sham controls ( Figure. B ). Moreover, degradation of elastin, demonstrated by the fragmentation of elastic fibers and the decreased number of lamellar units, was also observed in the dennervated aortas in comparison to the sham controls. While the control aortas were well innervated with perivascular nerve bundles adjacent to the adventitia, no nerves were found surrounding the denervated aortas, suggesting successful denervation. Conclusions: We generated an AAD model that could be used for mechanistic understanding and therapeutic development of AAA. The preliminary data suggest a direct link between the lack of aortic sympathetic innervation and AAA formation. Long-term studies are currently underway to further characterize changes in the aortic walls after sympathetic denervation. Figure.

Risk Of Rupture

Abdominal aortic aneurysm (AAA) is a potentially fatal condition with risk of rupture increasing as maximum AAA diameter increases. It is agreed upon that open surgical or endovascular treatment is indicated if maximum AAA diameter exceeds 5 to 5.5cm. Continuing aneurysmal degeneration of aortoiliac arteries accounts for significant morbidity, especially in patients undergoing endovascular AAA repair. Purpose of this review is to give an overview of the current evidence of medical treatment of AAA and describe prospects of potential pharmacological approaches towards prevention of aneurysmal degeneration of small AAAs and to highlight possible adjunctive medical treatment approaches after open surgical or endovascular AAA therapy.

Summary: Background: Main objective of this study was to evaluate the influence of statins and/or acetylsalicylic acid on biochemical characteristics of abdominal aortic aneurysm (AAA) wall and intraluminal thrombus (ILT). Patients and methods: Fifty patients with asymptomatic infrarenal AAA were analyzed using magnetic resonance imaging on T1w sequence. Relative ILT signal intensity (SI) was determined as a ratio between ILT and psoas muscle SI. Samples containing the full ILT thickness and aneurysm wall were harvested from the anterior surface at the level of the maximal diameter. The concentration of enzymes such as matrix metalloproteinase (MMP) 9, MMP2 and neutrophil elastase (NE/ELA) were analyzed in ILT and AAA wall; while collagen type III, elastin and proteoglycan 4 were analyzed in harvested AAA wall. Oxidative stress in the AAA wall was assessed by catalase and malondialdehyde activity in tissue samples. Results: Relative ILT signal intensity (1.09 ± 0.41 vs 0.89 ± 0.21, p = 0.013) were higher in non-statin than in statin group. Patients who were taking aspirin had lower relative ILT area (0.89 ± 0.19 vs 1.13. ± 0.44, p = 0.016), and lower relative ILT signal intensity (0.85 [0.73–1.07] vs 1.01 [0.84–1.19], p = 0.021) compared to non-aspirin group. There were higher concentrations of elastin in AAA wall among patients taking both of aspirin and statins (1.21 [0.77–3.02] vs 0.78 (0.49–1.05) ng/ml, p = 0.044) than in patients who did not take both of these drugs. Conclusions: Relative ILT SI was lower in patients taking statin and aspirin. Combination of antiplatelet therapy and statins was associated with higher elastin concentrations in AAA wall.

Abstract. Both coronary and peripheral artery disease are representative atherosclerotic diseases, which are also known to be positively associated with presence of abdominal aortic aneurysm. It is still controversial, however, whether coronary and peripheral artery disease are positively associated with expansion and rupture as well as presence of abdominal aortic aneurysm. In the present article, we overviewed epidemiological evidence, i. e. meta-analyses, regarding the associations of coronary and peripheral artery disease with presence, expansion, and rupture of abdominal aortic aneurysm through a systematic literature search. Our exhaustive search identified seven meta-analyses, which suggest that both coronary and peripheral artery disease are positively associated with presence of abdominal aortic aneurysm, may be negatively associated with expansion of abdominal aortic aneurysm, and might be unassociated with rupture of abdominal aortic aneurysm.

Abstract. This article analyses if and to what extent gender differences exist in abdominal aortic aneurysm (AAA) therapy. For this purpose Medline (PubMed) was searched from January 1999 to January 2018. Keywords were: “abdominal aortic aneurysm”, “gender”, “prevalence”, “EVAR”, and “open surgery of abdominal aortic aneurysm”. Regardless of open or endovascular treatment of abdominal aortic aneurysms, women have a higher rate of complications and longer hospitalizations compared to men. The majority of studies showed that women have a lower survival rate for surgical and endovascular treatment of abdominal aneurysms after both elective and emergency interventions. Women receive less surgical/interventional and protective medical treatment. Women seem to have a higher risk of rupture, a lower survival rate in AAA, and a higher rate of complications, regardless of endovascular or open treatment. The gender differences may be due to a higher age of women at diagnosis and therapy associated with higher comorbidity, but also because of genetic, hormonal, anatomical, biological, and socio-cultural differences. Strategies for treatment in female patients must be further defined to optimize outcome.
