INTRODUCTION: The repair of long-term complications of open abdominal aortic repair such as para-anastomotic aneurysm (PAA) and pseudoaneurysm (PSA) is very challenging. The aim of this study was to assess the outcomes of endovascular repair of PAA/PSA after previous open aortic surgery for aneurismal or occlusive disease. EVIDENCE ACQUISITION: A systematic review was undertaken; a search was performed (PRISMA) in MEDLINE, CENTRAL, Cochrane databases and key references of all studies of endovascular treatment of PAA/PSA after open aortic surgery...

BACKGROUND: Endovascular repair is now preferred to open access for the management of aortic diseases. This is typically performed via the femoral artery, however not all patients are eligible for this. This systematic review summaries the current evidence for utilising the carotid artery as an alternative access route. METHODS: A systematic review was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines using four electronic databases...

AIM: The Nellix was introduced to Asia in 2014. Data in Asians have been sparse. Two balloon expandable stents, each surrounded by a polymer-filled endobag are deployed in parallel to obliterate and seal the aneurysm. This paradigm shift to treating abdominal aortic aneurysms confers advantages for certain adverse aneurysm morphology that is outside the IFU for standard EVAR devices. We examine outcomes of fifteen Asian patients with concomitant infrarenal aortic and iliac artery aneurysms treated with the Nellix at our institution...

PURPOSE: Unfavorable anatomy is one of the major limitations of endovascular aortic aneurysm repair (EVAR) with specifically, adverse proximal neck morphology excluding many patients from receiving the standard endograft devices. Thoracic tube endografts have been used to overcome the issue of wide infrarenal necks, either as a sole device (single tubes or double tubes using the trombone technique) or as the proximal part of a bifurcated device fixed to the aortic bifurcation or infrarenally oriented...

We report the case of a 79-year-old man who was admitted to our department with acute limb ischemia due to the occlusion of the left iliac limb of an Endurant endograft. The admission computed tomography angiography revealed also a type IIIa endoleak due to modular disconnection of the iliac extensions from the right iliac limb of the endograft main body. Intrestingly, during the four year post-EVAR period, an increased kinking of the right limb has been observed leading to an almost cross-limb configuration of the limbs at the time of complications...

A 79-year-old male with diabetes mellitus and old cerebral infarction was admitted to hospital due to fever and palpitation. Diagnosis of purulent pericarditis was established by pericardial effusion examination. The patient's general condition improved temporarily after drainage of the pericardial effusion. However, computed tomography demonstrated a saccular aneurysm arising from RCA have rapidly grown even larger, up to 63 × 51 mm on 7th hospital day. This indicated that the risk of rupture of the aneurysm was high...

OBJECTIVE: Type II endoleaks (T2ELs) are commonly observed after endovascular aneurysm repair (EVAR). We sought to determine whether time at onset of T2ELs correlated with the need to intervene based on sac expansion or rupture. METHODS: Between 1998 and 2015, 462 EVARs performed at our institution had duplex ultrasound surveillance in our accredited noninvasive vascular laboratory. Computed tomography and arteriography were reserved for abnormal duplex ultrasound findings...

BACKGROUND: Short-term survival benefits of endovascular aneurysm repair (EVAR) compared with open repair (OR) of intact abdominal aortic aneurysms have been shown in randomised trials, but this early survival benefit is soon lost. Survival benefit of EVAR was unclear at follow-up to 10 years. OBJECTIVE: To assess the long-term efficacy of EVAR against OR in patients deemed fit and suitable for both procedures (EVAR trial 1; EVAR-1); and against no intervention in patients unfit for OR (EVAR trial 2; EVAR-2)...

Endovascular aneurysm sealing (EVAS) using the Nellix Endovascular Sealing System was introduced commercially in 2013 with the aim of reducing the incidences of reintervention and late complications observed after conventional endovascular aneurysm repair (EVAR). In the 5 years since its commercial launch, the Nellix system has evolved in terms of its structure, instructions for use, and delivery technique. Complications, including migration and proximal endoleak, have been recognized and treatment strategies developed, although durability remains to be demonstrated...

Endovascular aneurysm repair (EVAR) is a current alternative treatment for thoracic and abdominal aortic aneurysms, but is still sometimes compromised by possible complications such as device migration or endoleaks. In order to assist clinicians in preventing these complications, finite element analysis (FEA) is a promising tool. However, the strong material and geometrical nonlinearities added to the complex multiple contacts result in costly finite-element models. To reduce this computational cost, we establish here an alternative and systematic methodology to simplify the computational simulations of stent-grafts (SG) based on FEA...
