Para-anastomotic aortic aneurysms and progressive aneurysmal degeneration of the aorta after previous open aortic reconstruction pose a challenging clinical scenario. Due to the proximity to the visceral arteries, endovascular exclusion is typically not an option. However, the development of fenestrated and branched endografts has provided a less invasive means of ...

Electrocardiogram (ECG)-gated imaging offers insight into aortic shape changes throughout the cardiac cycle. Morphologic changes of the anchoring zones may influence stent graft fixation and sealing and may have serious implications for endograft design and durability. We used multiphase magnetic resonance imaging (MRI) scans to evaluate the asymmetric aspect of ...

PURPOSE: To assess the feasibility of endovascular thoracoabdominal aortic aneurysm (TAAA) repair using a standard off-the-shelf multi-branched stent-graft. METHODS: The aortic anatomy of 66 patients (45 men; mean age 74 years, range 57-87) referred for endovascular repair of TAAA was measured using 3-dimensional reconstructed images from computed tomographic angiograms. In ...

The original abdominal Excluder (W.L. Gore & Associates, Flagstaff, Ariz) endoprosthesis has been associated with late aneurysm sac expansion over time from transgraft ultrafiltration of serous fluid. This has been treated by relining the graft with original or low-permeability components. We asked whether additional component overlap of the original graft ...

Critical limb ischemia (CLI) is an endstage manifestation of peripheral artery disease (PAD) and typically describes patients with ischemic rest pain (Rutherford Category 4), or patients with ischemic skin lesions, either ulcers or gangrene (Rutherford Category 5-6). CLI due to infrapopliteal lesions is often not a good indication for infrageniculate ...

Endovascular repair (EVAR) is playing an increasingly role in the treatment of abdominal aortic aneurysm. A successful procedure depends on the complete sealing of the aneurysm sac from blood flow to achieve general pressure relief and avoid aneurysm rupture, with a shrinkage of the aneurysm sac. The most common complication ...

True abdominal aortic aneurysm (AAA) in patients with Marfan syndrome is relatively rare because most aortic aneurysms in this disease are dissecting aneurysms in the thoracic area. Therefore, its clinical characteristics and long-term outcome are still unclear. We examined six patients (3 men, 3 women) with Marfan syndrome who had ...

Endovascular treatment of thoracic aortic aneurysms is limited in patients with small or calcified femoral arteries, with the most serious complication being rupture at the insertion site or distal sections of the artery. To overcome this, an iliac conduit is normally created by surgical exposure. We used an original access ...

Disseminated intravascular coagulation (DIC) has been shown to affect 2% to 4% of patients with abdominal aortic aneurysms. In rare cases of DIC caused by aneurysms, operative repair has been curative. Endovascular aneurysm repair (EVAR) has been established as an effective treatment. We report a 73-year-old man in whom severe ...

The early experience of endovascular aneurysm repair (EVAR) using ''first generation'' devices was disappointing. There was an appreciable incidence of delayed, post-EVAR, aneurysm rupture. This was primarily a consequence of structural device failure. These failures provided important lessons for re-design and the modern ''second generation'' devices, including the Zenith (Cook ...

The introduction of ultrasound screening combined with the increasingly elderly population means that the number of small abdominal aortic aneurysms (AAAs) detected is expected to increase over the next decade. At present open or endovascular surgery are the only treatment options for AAA. In this mini-review we discuss the rationale ...
Verhagen H J M - - 2009
The evolution of stent-grafts and endovascular delivery systems has substantially improved the application rate for and patient outcomes with endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA), but further development is needed in order to reduce the continuing incidence of complications and secondary re-interventions. Severe angulations at the proximal ...
