Sutureless Clampless Telescoping Method for Aortic and Arterial Anastomoses Using an Endograft Connector

Complete renovisceral debranching and EVAR for thoracoabdominal aneurysm

Open graft repair of thoracoabdominal aortic aneurysms (TAAA) is an incredibly complex and challenging procedure with acceptable results achieved only by a few centers worldwide. Contemporary outcome analysis of TAAA repair performed in the United States showed greater operative mortality and morbidity rates than commonly reported. Moreover, a recent European long-term follow-up study showed that survival remains suboptimal, especially in the early years after TAAA repair. Complete renovisceral debranching combined with EVAR offers many advantages in regard to open surgical repair with comparable or better results, especially in the high-risk patient. Although this hybrid procedure will not…

Determining gA/gV with High-Resolution Spectral Measurements Using a LiInSe2 Bolometer

Neutrinoless double beta decay (0νββ) processes sample a wide range of intermediate forbidden nuclear transitions, which may be impacted by quenching of the axial vector coupling constant (gA/gV), the uncertainty of which plays a pivotal role in determining the sensitivity reach of 0νββ experiments. In this Letter, we present measurements performed on a high-resolution LiInSe2 bolometer in a “source = detector” configuration to measure the spectral shape of the fourfold forbidden β decay of 115In. The value of gA/gV is determined by comparing the spectral shape of theoretical predictions to the experimental β spectrum taking into account various simulated background components as well as a …

Use of the STAT (Sutureless Telescoping Anastomosis Technique) to facilitate supraaortic revascularization: Mid-term Results

The use of Endurant stent-graft for abdominal aortic aneurysm: the story about extension of instruction for use with persistent good results of stent-graft latest generation

The Endurant stent-graft (Medtronic, Inc., Minneapolis, MN, USA) is a latest generation device for the treatment of abdominal aortic aneurysm. The idea behind designing such a graft came from the intention to broad the instruction for use (IFU) and to enable it to treat more challenging anatomy including the 10mm neck lengths, and more severe suprarenal and infrarenal angulations. Endurant stent-graft has active fixation through suprarenal stent with anchoring pins to provide migration resistance, optimized heights of stents and spacing between them for improved flexibility and conformability, low-profile delivery system with hydrophilic coating and controlled simple deployment mechanism. S…

How to diagnose and treat abdominal compartment syndrome after endovascular and open repair of ruptured abdominal aortic aneurysms

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are frequently encountered in patients treated for ruptured abdominal aortic aneurysms (rAAA) and carry a high morbidity and mortality risk. Despite these facts, IAH/ACS are still overlooked by many physicians, timely diagnosis is missed and treatment often inadequate. All staff involved in the treatment of rAAA should be aware of the risk factors predicting IAH/ACS, the profound implications and derangements on all organ systems, the clinical presentation, the appropriate measurement of intra-abdominal pressure to detect IAH/ACS and the current treatment options for these detrimental syndromes. This comprehensive r…

Tips and tricks to make the ascending aorta accessible to EVAR

The ascending aorta is gaining increasing interest for endovascular specialists, as it opens the door to a potentially better way to treat aortic arch pathologies. Landing safely a stentgraft into the ascending aorta allows downgrading significantly the invasiveness of conventional open repair of the ascending aorta and/or aortic arch. Unfortunately, accessibility to the ascending aorta, in order to perform EVAR, can be challenging as the transfemoral approach might be cumbersome, or because the ascending aorta might not be appropriate for stentgraft landing. This paper will present some technical tips and tricks to achieve successful stentgraft landing in zone 0.
