Endovascular and Hybrid Management of Patients Affected by Abdominal Aortic Aneurysm and Occlusion of the Iliac Arteries.

The presence of a concomitant aortoiliac occlusive disease and abdominal aortic aneurysm (AAA) is rare and limits the implant of a bifurcated endograft.

Combined transcatheter treatment of severe aortic valve stenosis and infrarenal abdominal aortic aneurysm in increased surgical risk patients.

The prevalence of combined severe aortic stenosis and abdominal aortic aneurysm is increasing with the ageing of the population. Both conditions are associated with adverse outcome if not adequately managed. The choice of the optimal treatment of these patients is challenging and no clear recommendations are available. We report two cases of patients with concomitant severe symptomatic aortic stenosis and infrarenal abdominal aortic aneurysm successfully treated with combined transfemoral transcatheter aort...

Coronary Artery Disease as a Relevant Risk Factor in Screening of Abdominal Aortic Ectasia and Aneurysm.

An isolated aneurysm of the abdominal aorta in a patient with Marfan's syndrome - a case report.

We present a case of successfully treated abdominal aortic aneurysm in a 24-year old patient with Marfan's syndrome. Following initial physical and ultrasound examination, the multislice computed tomography scan revealed infrarenal aortic aneurysm of 6 cm in diameter, 10 cm long, along with slightly dilated iliac arteries. However, dimensions of aortic root, aortic arch and descending suprarenal aorta were within normal limits. Further on, since the patient presented with signs of impending rupture, an urge...

Endovascular repair of an abdominal aortic aneurysm using bifurcated stent-graft in a patient with bilateral external iliac artery occlusion.

Abdominal aortic aneurysm (AAA) in association with external iliac artery (EIA) occlusion is a rare entity which may limit endovascular aortic aneurysm repair (EVAR) feasibility. We describe the case of an 84-year-old man affected by a 64mm infrarenal inflammatory abdominal aortic aneurysm with complete bilateral occlusion of EIA and patency of both common and internal iliac arteries. The common femoral arteries (CFA) were patent, and the patient was asymptomatic for lower limb claudication. The treatment w...

Sex differences in national rates of repair of emergency abdominal aortic aneurysm.

The aim of this study was to assess the sex differences in both the rate and type of repair for emergency abdominal aortic aneurysm (AAA) in England.

Genetics of Thoracic and Abdominal Aortic Diseases.

Dissections or ruptures of aortic aneurysms remain a leading cause of death in the developed world, with the majority of deaths being preventable if individuals at risk are identified and properly managed. Genetic variants predispose individuals to these aortic diseases. In the case of thoracic aortic aneurysm and dissections (thoracic aortic disease), genetic data can be used to identify some at-risk individuals and dictate management of the associated vascular disease. For abdominal aortic aneurysms, gene...

AIM2 levels and DNA-triggered inflammasome response are increased in peripheral leukocytes of patients with abdominal aortic aneurysm.

Abdominal aortic aneurysm (AAA) is heavily infiltrated with leukocytes, expressing the DNA sensor absent in melanoma 2 (AIM2) and other inflammasome components.

Large diameter (≥29 mm) proximal aortic necks are associated with increased complication rates after endovascular repair for abdominal aortic aneurysm.

To investigate the impact of proximal aortic diameter on outcome after endovascular repair (EVAR) of infrarenal abdominal aortic aneurysms.

Abdominal Aortic Rupture Secondary To Lymphoma Recurrence.

Neoplasias affecting the aorta are usually due to a variety of thoracic and abdominal tumours, which are more common than primary tumours of the aortic wall. Those tumors that can invade the abdominal aorta are usually sarcomas, which are able to mimic, both clinically and radiologically, an aortic disease such as an aneurysm or a dissection. There are few clinical scenarios where surgical resection and aortic repair needs to be performed, and indications have not still been clearly established in the liter...

Cellular Mechanisms of Aortic Aneurysm Formation.

Aortic aneurysms are a common vascular disease in Western populations that can involve virtually any portion of the aorta. Abdominal aortic aneurysms are much more common than thoracic aortic aneurysms and combined they account for >25 000 deaths in the United States annually. Although thoracic and abdominal aortic aneurysms share some common characteristics, including the gross anatomic appearance, alterations in extracellular matrix, and loss of smooth muscle cells, they are distinct diseases. In recent...

Retroperitoneal Liposarcoma Masquerading As An Impending Rupture of Inflammatory Abdominal Aortic Aneurysm.

We present a unique case scenario of a periaortic liposarcoma masquerading as an impending rupture of an inflammatory abdominal aortic aneurysm (AAA).

EVAR approach for abdominal aortic aneurysm with horseshoe kidney: a multicenter experience.

Horseshoe kidney is a congenital abnormality, with an incidence of 0.25% of the total population. Only 0.12% of patients who undergo an abdominal aortic aneurysm repair might also have a coexisting horseshoe kidney. We present a series of ten cases auspiciously treated with an endovascular approach along with their respective patient evolutions. A review of the literature is also presented.

Endovascular treatment of abdominal aortic aneurysm and aortic bifurcation stenosis by unibody bifurcation stent graft.

To sum up experience in unibody bifurcation stent graft in the treatment of abdominal aortic aneurysm with aortic bifurcation stenosis.

Using bifurcated endoprosthesis after iliac artery recanalization for concomitant abdominal aortic aneurysm and chronic total occlusions of access routes.

Concurrent abdominal aortic aneurysm (AAA) and unilateral iliac occlusion is a challenge in the implantation of bifurcated stent grafts (BFGs). The endovascular approach is less invasive than open surgery; the aortouni-iliac (AUI) graft with crossover femorofemoral bypass (CFFB) has many problems associated with extra-anatomic reconstruction. We attempted endovascular aneurysm repair (EVAR) using BFGs in such cases and evaluated the outcomes.

CD95-Ligand contributes to abdominal aortic aneurysm progression by modulating inflammation.

Abdominal aortic aneurysm (AAA) is one of a number of diseases associated with a prominent inflammatory cell infiltration, matrix protein degradation, and smooth muscle cell apoptosis. CD95 is an inflammatory mediator and an apoptosis inducer. Previous studies have shown elevated expression of CD95 or CD95L in the aortic tissue of AAA patients. However, how the CD95L/CD95 contributes to aneurysm degeneration and whether blocking its signaling would be beneficial to disease progression remains largely unknow...

Interleukin-6 Receptor Signalling and Abdominal Aortic Aneurysm Growth Rates.

The Asp358Ala variant (rs2228145; A>C) in the interleukin-6 receptor ( IL6R) gene has been implicated in the development of abdominal aortic aneurysms (AAAs), but its effect on AAA growth over time is not known. We aimed to investigate the clinical association between the IL6R-Asp358Ala variant and AAA growth, and to assess the effect of blocking the IL-6 signalling pathway in mouse models of aortic aneurysm rupture or dissection.

Evolution of practices in Treatment of abdominal aortic aneurysm in France between 2006 and 2015.

The main objective of this study was to identify the changes that have occurred in the treatment of abdominal aortic aneurysms (AAA) in France over a period of 10 years.

DAB2IP Expression in Abdominal Aortic Aneurysm: EZH2 and mir-363-3p as Potential Mediators.

Nine genetic loci have been associated with abdominal aortic aneurysm (AAA) susceptibility, including DAB2IP. This gene is playing a role in apoptosis, cell proliferation and epithelial-to-mesenchymal transition in cancers. This study aimed to elucidate the differential expression levels of DAB2IP in AAA tissues and investigate whether mir-363-3p and EZH2 can be considered as potential mediators of its expression.

Infra-renal vs supra-renal abdominal aortic aneurysms: Comparison of associated aneurysms and renal artery stenosis.

The aim of our study was to assess the prevalence of concomitant arterial abnormalities (true aneurysms of iliac, common femoral, renal, visceral arteries and stenoses of iliac and renal arteries) in patients with abdominal aortic aneurysm, and to evaluate whether the type of the aneurysm (suprarenal versus solely infrarenal) is associated with this prevalence.

Meta-analysis of long-term survival after elective endovascular or open repair of abdominal aortic aneurysm.

Endovascular aneurysm repair (EVAR) has become the preferred strategy for elective repair of abdominal aortic aneurysm (AAA) for many patients. However, the superiority of the endovascular procedure has recently been challenged by reports of impaired long-term survival in patients who underwent EVAR. A systematic review of long-term survival following AAA repair was therefore undertaken.

Increasing surgeon volume correlates with patient survival following open abdominal aortic aneurysm repair.

The annual number of open abdominal aortic aneurysm (AAA) repairs has decreased dramatically over the last decade, making the search for physician case volume thresholds more important. The purpose of this study was to identify a minimum threshold for annual surgeon case volume in open AAA repair.

Rupture of a totally occluded abdominal aortic aneurysm.

Totally occluded aortic aneurysm is a rare pathology. The medical history and the evolution are unknown. We present a case of a regular followed 60 years old man with chronic thrombosed aneurysm presenting with mycotic acute rupture. As an original treatment, the patient was treated by aortic ligation without distal revascularization. A literature review from 1974 to 2015 enhances the contemporary understanding of the pathology, by exploring the thrombus interaction, pressure and the wall shear stress. The ...

CT and 3D-ultrasound registration for spatial comparison of post-EVAR abdominal aortic aneurysm measurements: A cross-sectional study.

The aim of the present study is to provide a methodology to register volumes of stented abdominal aortic aneurysm, imaged by 3D-US and CT modalities. After registration, the method enables to compare the spatial location of measurements and AAA size in a common coordinate system.
