“…A few years later, an evolution of the Enovus was proposed for human application with the name of Ovation Endograft (Endologix, Irvine, CA, USA). After successful animal investigations [72], the platform was tested in clinical trials with positive feedback, which was a fundamental evolution in the use of polymers in the EVAR field. The endograft is based on a new concept design separating fixation from sealing-fixation activity is assured by a suprarenal stent and anchors (not different from traditional suprarenal EVAR devices), while sealing activity is based on inflatable O-rings filled with a low-viscosity, non-embolic, radiopaque fill polymer instead of traditional self-expanding stent grafts.…”

An abdominal aortic aneurysm (AAA) is a dilatation of the abdominal aorta that progressively grows until it ruptures. Treatment is typically recommended when the diameter is more than 5 cm. The EVAR (Endovascular aneurysm repair) is a minimally invasive procedure that involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. For years, stent grafts’ essential design was based on metallic stent frames to support the fabric. More recently, a polymer-based technology has been proposed as an alternative method to seal AAA. This review underlines the two platforms that are based on a polymer technology: (1) the polymer-filled endobags, also known as Endovascular Aneurysm Sealing (EVAS) with Nellix stent graft; and (2) the O-ring EVAR polymer-based proximal neck sealing device, also known as an Ovation stent graft. Polymer characteristics for this particular aim, clinical applications, and durability results are hereby summarized and commented critically. The technique of inflating endobags filled with polymer to exclude the aneurysmal sac was not successful due to the lack of an adequate proximal fixation. The platform that used polymer to create a circumferential sealing of the aneurysmal neck has proven safe and effective.

“…In addition, although mortality rates are reasonably low in uncomplicated cases (5%), higher rates are often associated in those with co-morbid diseases such as coronary artery disease and renal failure. 46 OSR may also result in significant harm to the patient, with myocardial infarction, respiratory and renal failure, and changes in functional status possibly occurring. 71,123 Finally, recovery rates are in the region of several months, resulting in a reduction in quality of life for the patients for up to 3 months post-operatively.…”

AAA Stent–Grafts: Past Problems and Future Prospects

Endovascular aneurysm repair (EVAR) has quickly gained popularity for infrarenal abdominal aortic aneurysm repair during the last two decades. The improvement of available EVAR devices is critical for the advancement of patient care in vascular surgery. Problems are still associated with the grafts, many of which can necessitate the conversion of the patient to open repair, or even result in rupture of the aneurysm. This review attempts to address these problems, by highlighting why they occur and what the failings of the currently available stent grafts are, respectively. In addition, the review gives critical appraisal as to the novel methods required for dealing with these problems and identifies the new generation of stent grafts that are being or need to be designed and constructed in order to overcome the issues that are associated with the existing first- and second-generation devices.

“…[7][8][9][10] Endovascular therapy is a minimally invasive technique that has been widely used to treat various vascular diseases, especially abdominal and thoracic aortic aneurysms. [11][12][13][14] Recently, several studies have reported the management of IVIs with endovascular techniques. 15,16 In this study, we aimed to evaluate the application of endovascular techniques including endograft placement, embolization and balloon compression in the treatment of different types of IVIs.…”

The purpose of this study was to evaluate the outcome of endovascular management of iatrogenic vascular injuries (IVIs). We retrospectively reviewed the clinical records of 19 consecutive patients who underwent endovascular therapy of IVIs. Endograft implantation was conducted in 13 patients, intravascular embolization using coil was performed in four patients, combined treatment involving endovascular balloon intervention and percutaneous thrombin injection was done in one patient and the remaining one patient received balloon compression for hemostasis. There were no deaths after the operation. In the patients with vessel rupture (n = 9) or perforation (n = 4), cessation of bleeding and restoration of blood flow were achieved following the endovascular treatments. Four cases of pseudoaneurysm and one case of arteriovenous fistula were successfully eliminated. At a median follow-up of 23.8 months (range 484), one patient suffered a mild cerebral infarction secondary to covered stent placement and one patient developed a partial renal infarction secondary to coil embolization. Additionally, stent collapse was found in one patient with stenosis of the iliofemoral vein, accounting for the failure to resolve the lower limb edema. In conclusion, endovascular therapy is an effective technique in the management of different types of IVIs, but is associated with minor ischemic complications.
