Internal carotid artery (ICA) aneurysms are rare. The symptoms are related to cerebral embolization, local compression and rupture. Options for treatment include open surgery or endovascular treatment with a covered stent. We report a case of a 67 year old woman with bilateral idiopathic internal carotid artery aneurysms, found during ...

OBJECTIVE: Endovascular Abdominal Aortic Aneurysm Repair (EVAR) has been criticized because of the need for frequent secondary interventions (2ndINT) to maintain effective abdominal aortic aneurysm (AAA) exclusion. The study goal is to detail such interventions and determine their effect on clinical outcomes. METHODS: From January 1997 to December 2007, 832 ...

Improvements in the design of endovascular grafts are based on lessons learned from difficulties encountered with prior-generation devices. The most common difficulties in device design relate to how the device is delivered and how it can safely and durably fix the aneurysm. This concept is especially true in patients with ...

Rupture of abdominal aortic aneurysms (AAA) is a devastating event potentially preventable by therapies that inhibit growth of small aneurysms. Receptor of advanced glycation end products (RAGE) has been implicated in age related diseases including atherosclerosis and Alzheimer. Consequently, we explored whether RAGE may also contribute to the formation of ...

Type II endoleak is a common phenomenon after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). Most type II endoleaks are innocuous and transient and therefore do not require intervention. However, particularly persistent endoleaks could lead to aneurysm enlargement and delayed aortic rupture. Decreasing the occurrence rates of type ...

Repair of abdominal aortic aneurysms by endovascular means is the preferred method in most patients. Despite its popularity, questions remain about the long-term efficacy and durability. Proximal migration and endoleak are associated with significant morbidity and mortality, and are two of the most important factors in achieving a successful outcome. ...

Inadequate iliac artery diameter, calcification, and tortuosity are associated with increased incidence of iliac injury during abdominal (EVAR) and thoracic endovascular aneurysm repair (TEVAR). Despite careful preoperative assessment and use of iliac conduits, inadvertent iliac rupture is a source of morbidity and mortality. This report details our single-center, 10-year experience ...

The etiology of abdominal aortic aneurysm (AAA) includes inflammation and endothelial dysfunction. To evaluate relations between these mechanisms and AAA growth, endothelin (ET)-1, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and CD40 ligand were related to yearly AAA growth for 2.9 +/- 1.6 years (mean +/- SD) in 178 patients with ...

Abdominal aortic aneurysm (AAA) is a common and life-threatening disease characterized by progressive dilatation and rupture, and has a mortality rate of up to 90%. Surgical repair is recommended for large aneurysms, whereas small aneurysms are managed by 'watchful waiting'. The recently introduced AAA screening programs reduce aneurysm-related mortality; however, ...

Successful endovascular repair of abdominal aortic aneurysms (AAA) requires undilated proximal (infrarenal neck) and distal landing zones (common or external iliac arteries). A range of approved endografts are available to exclude such aneurysms. Recent multicentric prospective randomized trials have demonstrated a short and midterm decrease in aneurysm-related deaths of the ...

The technique of endovascular repair of abdominal aortic aneurysm has markedly improved over the years, showing a lower 30-day mortality rate compared to the open technique. Despite improvements, the percentage of reinterventions remains high due to late failure. A rare but severe complication of EVAR is the development of an ...

The pathogenesis of aortic aneurysms remains unclear. There is epidemiologic and histologic evidence showing significant differences in aneurysms of the thoracic and abdominal aorta. Studies suggest that abdominal aortic aneurysms (AAA) may represent a local manifestation of a systemic dilating diathesis. It is not known whether thoracic aortic aneurysms (TAA) ...
Button M C J - - 2009
The recent advances in stent technology have provided a choice of techniques in the treatment of thoracoabdominal aortic aneurysms. These techniques should reduce the physiological insult associated with aneurysm repair. Because numbers are small and these techniques are still being perfected, there is as yet limited evidence for a significantly ...

Endovascular aneurysm repair (EVAR) is a well-established alternative to open surgery. The presented case underwent endovascular therapy of an abdominal aortic aneurysm (AAA) with the anatomical prerequisite of a horseshoe kidney. We describe the technique used, including the embolization of aortic side branches, to avoid endoleaks, and the management of ...

Endovascular treatment of descending thoracic aortic pathologies requires a preoperatively determined interventional strategy. Its feasibility depends mainly on anatomic factors: the morphology of the proximal and distal fixation sites, the diameter and disease state of the access vessels. These factors represent important predictors of success and the most important exclusion ...

In the trend of the endovascular revolution for occlusive arterial disease, management of aneurysmal disease has known an analogous change in the nineties. Elective endo-aneurysmal stentgrafting (EVAR or endovascular aneurysm repair) is nowadays of widespread application in contemporary practice all over the world, sometimes by over-enthusiast proponents. There is a ...

The repair of abdominal aortic aneurysm (AAA) in the presence of significant coronary artery disease (CAD) carries a high-risk of adverse peri-operative cardiac event. The options to reduce cardiac risk include perioperative beta-blockade, preoperative optimization by myocardial revascularization and simultaneous (combined) coronary artery bypass grafting and aneurysm repair. We describe ...

Inflammatory abdominal aortic aneurysm (IAAA) is characterized by inflammatory and/or fibrotic changes in the periaortic regions of the retroperitoneum. Surgical repair is usually selected for this disease. However, the perioperative mortality associated with open surgical repair of IAAs is three times higher than that with noninflammatory aortic aneurysms due to ...

METHODS: This is a retrospective review of 68 consecutive patients who underwent emergency repair of RAAA. Baseline pulmonary artery pressure, ...
Hoegh Annette - - 2009
BACKGROUND: This study investigates whether baseline aortic wall distensibility serves as a supplemental bio-marker for AAA progression and need for later repair. METHODS: In 1998, 61 males with a small asymptomatic AAAs had a baseline measurement of elasticity and stiffness, using an echo-tracking ultrasound system (Diamove). The cohort was followed ...
Hellenthal Femke A M V I - - 2009
Defining progression of abdominal aortic aneurysm (AAA) is complicated by several factors, including measurement error, duration of follow-up, and the imaging modality used to assess AAA expansion. Investigations of biomarkers of AAA progression should be standardized so that valid comparisons can be made. Previous research has shown some promising advances ...
Verhoeven E L - - 2009
BACKGROUND: Recent developments with fenestrated and branched stent grafts have opened the way to treat complex aortic aneurysms involving the visceral arteries. Early reports on endovascular treatment of thoraco-abdominal aneurysms have demonstrated the feasibility of the technique. Given the sparse literature, its safety has not been established yet. METHODS: A ...
