We report a case in which saccular aneurysms formed at both ends of an endograft that exhibited maladaptive aortic changes after endovascular aortic repair in a patient without significant evidence of connective tissue disease. A 66-year old male underwent thoracic endovascular aortic repair (TEVAR) for a distal aortic arch aneurysm. A follow-up computed tomography (CT) scan performed at 6 mont...

OBJECTIVE Endograft mural thrombus has been associated with stent graft or limb thrombosis after endovascular aneurysm repair (EVAR). This study aimed to identify clinical and morphologic determinants of endograft mural thrombus accumulation and its influence on thromboembolic events after EVAR. METHODS A prospectively maintained database of patients treated by EVAR at a tertiary institution ...

Let a(z) be a meromorphic function having in the disk |z| < R precisely λ poles. In this work for the (λ−1)th row of the Padé table of a(z) the set of uniform convergence is explicitly obtained. The present note is a supplement to the previous work of the author (J. Approx. Theory, 123(2003), 160-207). In the theory of uniform convergence of the Padé approximants the principal question is if th...

BACKGROUND Endovascular option has been proposed for a very limited and selected number of Stanford type A aortic dissection (TAAD) patients. We have performed a computed tomography (CT)-based TAAD study to explore appropriate endograft configurations for the ascending aortic pathology. METHODS TAAD patients treated with optimal CT scans were retrospectively reviewed, and their entry tears (E...

The late removal of an abdominal aortic endograft is technically challenging and can be associated with significant blood loss, especially when a graft with active suprarenal fixation is involved. The main issue in safe explantation of the endograft is control of the aorta above the proximal fixation site. We report an adjunctive technique for the safe and fast proximal control of the suprarena...

A 77-year old woman who underwent hybrid aortic arch repair using a Gore-TAG (Gore-Associates, Flagstaff, AZ, USA) endograft (Fig. 1A) complained of chest pain 5 months after operation. Blood cultures revealed Serratia marcescens. Computed tomography (CT) demonstrated dislocation of the endograft with formation of a pseudoaneurysm (Fig. 1B). Ascending aorta replacement with re-debranching was e...

BACKGROUND Lifelong surveillance after endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) is considered mandatory to detect potentially life-threatening endograft complications. A minority of patients require reintervention but cannot be predictively identified by existing methods. This study aimed to improve the prediction of endograft complications and mortality, through the appli...

PURPOSE To determine if lateral movement of an aortic endograft 1 year following endovascular abdominal aortic aneurysm (AAA) repair is an indicator of endograft instability and can serve as a predictor of late adverse events. METHODS The records of 60 high-risk AAA patients (52 men, 8 women; mean age 74 years) who were treated with infrarenal (n = 38) or suprarenal (n = 22) endografts and ha...

The learning of the shape and appearance behavior of complex anatomical structures is of growing importance in the successful use of medical imaging data. We propose a method to simultaneously learn a model of shape variation and the behavioral structure of objects in volumetric data sets. The algorithm performs a group-wise registration of a set of examples, and accounts for the heterogeneous ...

We report a rare case of massive type IIIb endoleaks from an abdominal endograft, which were difficult to diagnose and required hybrid repair (including open surgery). The patient had previously undergone three catheter interventions for type Ia and II endoleaks after abdominal endografting. However, the abdominal aortic aneurysm gradually enlarged and required hybrid treatment (including an op...
