BACKGROUND: To decrease the morbidity associated with cut-downs during endovascular aneurysm repair, some authors have suggested the totally percutaneous endovascular repair (PEVAR). The goal of this report is to evaluate and describe our centre's experience with the total percutaneous endovascular aneurysm repair (PEVAR) for aortic abdominal aneurysm (AAA). METHODS: We ...

Inflammatory abdominal aortic aneurysms (IAAA) can present significant challenges to surgeons, especially in the juxtarenal location where they may not be amenable to endovascular repair. The dense, inflammatory component of these lesions can encase adjacent structures including the duodenum, ureters, and inferior vena cava putting them at risk for injury ...

Abdominal aortic aneurysms (AAA) have a prevalence between 1.3-8.9% in men and 1.0-2.2% in women aged above 55 years. Furthermore, AAA cause 1-3% of all deaths among men aged 65-85 years in developed countries. As the disorder is invariably associated with severe atherosclerotic damage of the arterial wall, it has ...

Endovascular aneurysm repair (EVAR) is an established therapy to prevent rupture in large infrarenal abdominal aortic aneurysms (AAA). As experience with this therapy has grown, treatment of more challenging anatomy has led to the identification of several new procedurally related complications. We report the case of a 67-year-old man with ...

The combination of Trans-Atlantic Intersociety Consensus (TASC) D aortoiliac occlusive disease as well as a symptomatic abdominal aortic aneurysm (AAA) is not a common occurrence. Extensive calcified atherosclerotic disease, occlusions, and small iliofemoral segmental arteries make transfemoral access difficult, if not impossible, for endovascular aneurysm repair (EVAR) in these patients. ...

Adequate seal at the proximal and distal extent of stent grafts in the aorta is paramount to the success of thoracic endovascular aortic repair (TEVAR). Thoracoabdominal aneurysms pose a formidable challenge given their extension into the arch branches proximally and the visceral segment distally. Extension of the landing zone of ...

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 ...
Conrad Mark F - - 2009
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 ...
Cayne Neal S - - 2009
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 ...
Jonker Frederik H W - - 2009
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 ...

Endovascular treatment of ruptured abdominal aortic aneurysms is associated with decreased morbidity and mortality when compared to the open surgical approach, yet, there are several fundamental obstacles to our ability to offer these endovascular techniques to many patients with ruptured aneurysms. This article will focus on the technical aspects of ...

Atherosclerotic plaques are a feature of abdominal aortic aneurysms (AAAs). Atherosclerosis and AAA appear to share similar risk factors. These observations have led to the conclusion that AAAs are a consequence of advanced atherosclerosis.This review explores current theories regarding the pathogenesis of AAA and their implications for treatment.A systematic literature ...

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. ...

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 ...

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 ...

Incompetence of the left atrioventricular valve remains the final Achilles' heel of repair of atrioventricular septal defects (AVSDs), despite low operative mortality in the modern era. We have analysed the morphological basis for valvar incompetence in our own series of repairs, and in doing so, reviewed the morphology of the ...

The authors present the case of a 39-year-old man who underwent endovascular repair of a thoracic aortic disruption. Implantation of a Gore TAG stent-graft achieved total exclusion of the traumatic lesion with no contrast extravasation. However, on the third postoperative day, the patient developed complete anuria necessitating continuous venovenous hemofiltration. ...

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 ...

Barnett Brad P - - 2009
Hybrid surgical and endovascular approaches such as open visceral vessel debranching and subsequent endovascular exclusion of thoracic abdominal aortic aneurysms (TAAA) represents a significant development in treatment of TAAAs. As compared to traditional endovascular aneurysm repair, hybrid repairs commonly have a higher rate of endoleak and other endograft-related complications. In ...

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 ...
Nordon Ian - - 2009
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 ...
