OBJECTIVE: To assess prevalence of aortic involvement in relapsing polychondritis (RP) patients; to evaluate clinical features and long-term outcome of RP patients exhibiting aortitis, aortic ectasia and/or aneurysm. METHODS: 172 RP patients underwent aortic computed tomography (CT)-scan; they were seen in 3 medical centers. RESULTS: 11 patients (6.4%) had aortic involvement, occurring within a median time of 2 years after RP diagnosis. CT-scan showed isolated aortitis (n=2); the 9 other patients exhibited: aortitis and aortic aneurysm (n=2) or ectasia (n=1), isolated aortic aneurysm (n=4) or ectasia (n=2); aortic localizations were as follows: thoracic (n=6), abdominal (n=2), thoracic and abdominal (n=4) aorta...

The prevalence of abdominal aortic aneurysm (AAA) is reported to be 2.2%-8% among men >65 years. During recent years, screening programs have been developed to detect AAA, prevent ruptures, and thereby saving lives. Therefore, most men with the diagnosis are monitored conservatively with regular reviews. The objective of the study was to describe how men diagnosed with abdominal aortic aneurysm <55 mm discovered by screening experience the process and diagnosis from invitation to 1 year after screening...

OBJECTIVES: Outcomes after endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (rAAAs) have been widely published. There is, however, controversy on the role of the use of aortouniiliac endoprosthesis (AUI) versus modular or unibody bifurcated endoprosthesis (MUB) for repair of rAAAs. We study and compare 30-day outcomes after use of AUI and MUB for all rAAAs focusing specifically on patients with instability. MATERIALS AND METHODS: Patients who underwent EVAR for rAAA (n = 425) using AUI (n = 55; 12...

BACKGROUND: The reported 54 mm median intervention diameter for endovascular aneurysm repair (EVAR) in the Vascular Quality Initiative and European data from the Pharmaceutical Aneurysm Stabilisation Trial (PHAST) implies that in real life the majority of abdominal aortic aneurysm (AAA) repairs occur at diameters smaller than the consensus intervention threshold of 55 mm. This study explores the potential consequences of this practice. METHODS: The differences between real life AAA repair and consensus based intervention threshold were explored in reported data from vascular quality initiatives and PHAST...

OBJECTIVE: Diabetes counteracts formation and rupture of abdominal aortic aneurysms, possibly through arterial matrix accumulation. Use of metformin, on the other hand, reduces arterial accumulation of matrix molecules. Consequently, we hypothesized that metformin treatment may reverse the protective role of diabetes on the development and course of aneurysms, that is, that metformin would be associated with aneurysm rupture among individuals with diabetes. METHODS: Using nationwide Danish registry data, we performed a nested case-control study on the association between long-term use of metformin and ruptured abdominal aortic aneurysm (RAAA)...

OBJECTIVE: Visceral artery aneurysms (VAAs) are rare but often repaired because of dire consequences of rupture. This is a population-based evaluation of chronologic trends in management, risk factors, and outcomes of endovascular and open therapy. METHODS: The 2003 to 2013 Agency for Healthcare Research and Quality (AHRQ) National Inpatient Sample (NIS) database was reviewed. Cases with primary diagnosis of VAA and undergoing endovascular or open repair were identified...

Endovascular or open surgery for elective abdominal aortic surgery? Evidence from the 5 randomized trials OAR (open aortic repair) can be demanding for fragile patients, but has good long-term durability. EVAR (endovascular aortic repair) is more lenient, but is associated with life-long controls, more life-threatening reinterventions, a remaining threat of rupture and a possibly increased risk of death by cancer. All patients with an AAA (abdominal aortic aneurysm) must recieve a thorough evaluation of medical risk and expected survival before open/endovascular treatment and a discussion of the short- and long-term risks of the different treatment alternatives...

Aneurysmal degeneration of distal landing zones after endovascular aneurysm repair (EVAR), can be a potential cause of late failure of this technique. Aneurysmal degeneration of common iliac arteries increases the risk of rupture of the iliac aneurysm itself as well as of the abdominal aortic aneurysm (AAA) owing to aneurysm's reperfusion as a type Ib endoleak. Reoperation consists in plugging and covering the internal iliac artery (IIA), by extension into the external iliac artery, or preservation of antegrade flow in IIA by iliac branch devices (IBD) or sandwich technique...

This report presents the surgical repair and postsurgical outcomes following a ruptured infrarenal aortic aneurysm with a maximum transverse diameter of 20 cm. Its association with acute lower limb motor deficit is rare. Open surgery of giant abdominal aortic aneurysms is often the only available treatment, favored over an endovascular approach in the presence of increased aneurysm size with dislodged abdominal organs, adhesions, and short and angled proximal infrarenal aortic neck, presenting significant additional surgical and anesthesiological challenges...

BACKGROUND AND AIMS: The pathogenesis of abdominal aortic aneurysm (AAA) shares several common pathways with atherosclerosis. Prospective clinical plasma biomarker studies in AAA have been hampered by the need for very large cohorts and long follow-up time. METHODS: We analyzed a prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer study (n = 5551; 1991-94). The plasma biomarkers lipoprotein-associated phospholipase A2 (Lp-PLA2 activity and mass), proneurotensin and C-reactive protein, and conventional risk factors at baseline were measured in patients with incident AAA during follow-up, and compared to individuals without a diagnosis of AAA...

OBJECTIVE: Thrombin-activatable fibrinolysis inhibitor (TAFI) reduces the breakdown of fibrin clots through its action as an indirect inhibitor of plasmin. Studies in TAFI-deficient mice have implicated a potential role for TAFI in Abdominal Aortic Aneurysm (AAA) disease. The role of TAFI inhibition on AAA formation in adult ApoE-/- mice is unknown. The aim of this paper was to investigate the effects of TAFI inhibition on AAA development and progression. METHODS: Using the Angiotensin II model of AAA, male ApoE-/- mice were infused with Angiotensin II 750ng/kg/min with or without a monoclonal antibody inhibitor of plasmin-mediated activation of TAFI, MA-TCK26D6, or a competitive small molecule inhibitor of TAFI, UK-396082...

BACKGROUND: Abdominal aortic aneurysm (AAA) is an abnormal dilatation of the infradiaphragmatic aorta that is equal to or greater than 30 mm or a local dilatation of equal to or greater than 50% compared to the expected normal diameter of the artery. AAAs rarely occur in individuals under 50 years of age, but thereafter the prevalence dramatically increases with age, with men at a six-fold greater risk of developing an AAA than women. Prevalence of AAA has been reported to range from 1...

Endovascular aneurysm repair (EVAR) is first-choice treatment for many patients with abdominal aortic aneurysms. Complications unique to endovascular treatment include endoleak and endotension, which can eventually lead to rupture. We present two cases of late aortic rupture after EVAR, where both patients had recent preceding catheter-directed thrombolysis with urokinase for acute limb ischemia. These cases suggest a relation between thrombolytic therapy and aortic rupture after EVAR, and we should therefore be aware of this possible complication...

True atherosclerotic aneurysms of superficial femoral artery (SFA) are rare and often associated with other peripheral or aortic aneurysms. We report the case of a 84-year-old patient presenting a giant degenerative ruptured aneurysm of the superficial femoral artery. The patient underwent successful aneurysm resection and bypass grafting, with a satisfying long-term follow-up and patency of the graft. The patient was also operated one year before, for a ruptured aneurysm of the abdominal aorta. This case report is rare, because we described a case of patient with multiple atherosclerotic aneurysms, who present, for the second time, a life threating ruptured aneurysm...

BACKGROUND: Perigraft hygromas or seromas are an unusual finding and/or complication after open aortic repair. CASE REPORT: We present a case of an 82 year-old man with a previous urgent aortic bifurcated graft for abdominal aortic aneurysm (AAA) rupture. He received several treatments due to abdominal compartment syndrome (ACS), requiring a Bogota Bag and colostomy derivation. He was finally discharged home and lost on follow-up. Eight years after this procedure he presented to the urgency department with an abdominal mass and pain...

PURPOSE: Abdominal aortic aneurysm (AAA) is a localized, permanent and irreversible enlargement of the artery, with the formation of thrombus into the inner wall of the aneurysm. A precise patient-specific segmentation of the thrombus is useful for both the pre-operative planning to estimate the rupture risk, and for post-operative assessment to monitor the disease evolution. This paper presents a generic approach for 3D segmentation of thrombus from patients suffering from AAA using computed tomography angiography (CTA) scans...

An Abdominal Aortic Aneurysm (AAA) is a permanent focal dilatation of the abdominal aorta at least 1.5 times its normal diameter. The criterion of maximum diameter is still used in clinical practice, although numerical studies have demonstrated the importance of biomechanical factors for rupture risk assessment. AAA phantoms could be used for experimental validation of the numerical studies and for pre-intervention testing of endovascular grafts. We have applied multi-material 3D printing technology to manufacture idealized AAA phantoms with anisotropic mechanical behavior...
