National temporal trends and determinants of cost of abdominal aortic aneurysm repair.

Introduction: In recent decades, there has been a shift in the management of aortic abdominal aneurysm from open intervention (open aortic aneurysm repair) to an endovascular approach (endovascular aortic aneurysm repair). This shift has yielded clinical as well as socioeconomic reverberations. In our current study, we aim to analyze these effects brought about by the switch to endovascular treatment and to scrutinize the determinants of cost variations between the two treatment modalities.

Trends of vascular surgery procedures in Marfan syndrome and Ehlers-Danlos syndrome.

Objectives: Marfan syndrome and Ehlers-Danlos syndrome represent two connective tissue vascular diseases requiring unique consideration in their vascular surgical care. A comprehensive national review encompassing all hospitalizations for the Marfan Syndrome and Ehlers-Danlos syndrome patient population is lacking.

Methods: The National (Nationwide) Inpatient Sample from 2010 to 2014 was reviewed for all inpatient vascular surgery procedures including those with a diagnosis of Marfan syndrome and Ehlers-Danlos syndrome.

Successful left gonadal vein to inferior vena cava bypass for symptomatic May-Thurner syndrome.

We report the management of symptomatic May-Thurner syndrome refractory to endovascular techniques with left gonadal vein to inferior vena cava bypass. The patient's presentation was exceptional-a young individual with end-stage renal disease status post four failed kidney transplants, dwindling options for dialysis access, and an unusable left thigh arteriovenous graft owing to severe lower extremity edema secondary to common iliac vein compression. Postoperatively, swelling was markedly alleviated and the thigh graft was functional.

Axillary Artery Access for Combined Endoaortic Balloon Occlusion and Perfusion During Robotic Mitral Valve Surgery.

We aimed to develop a method that provides an alternative cannulation site in robotic mitral valve surgery that allows simultaneous endo-occlusion and antegrade perfusion. A 71-year-old man with severe mitral regurgitation and history of coronary artery bypass grafting underwent totally endoscopic robotic mitral valve repair. A 23-mm endoreturn cannula was placed through a 10-mm graft that was sewn to the left axillary artery.

Noncardiac Surgical Procedures After Left Ventricular Assist Device Implantation.

As left ventricular assist devices (LVADs) are increasingly used for patients with end-stage heart failure, the need for noncardiac surgical procedures (NCSs) in these patients will continue to rise. We examined the various types of NCS required and its outcomes in LVAD patients requiring NCS. The National Inpatient Sample Database was examined for all patients implanted with an LVAD from 2007 to 2010.

Right ventricular assist device results in worse post-transplant survival.

Background: To our knowledge, how the need for a right ventricular assist device (RVAD) with a left ventricular assist device (LVAD) affects outcomes after orthotopic heart transplantation has not been studied in a multi-institutional database.

Methods: The United Network for Organ Sharing (UNOS) database was queried for all adult orthotopic heart transplantations from the period 2005-2012. Patients requiring a RVAD + LVAD as a bridge to transplant were compared with patients requiring a LVAD only and patients requiring no ventricular assist device (VAD).

Examining Noncardiac Surgical Procedures in Patients on Extracorporeal Membrane Oxygenation.

As extracorporeal membrane oxygenation (ECMO) is increasingly used for patients with cardiac and/or pulmonary failure, the need for noncardiac surgical procedures (NCSPs) in these patients will continue to increase. This study examined the NCSP required in patients supported with ECMO and determined which variables affect outcomes. The National Inpatient Sample Database was examined for patients supported with ECMO from 2007 to 2010.

Examining ABO compatible donors in double lung transplants during the era of lung allocation score.

Background: The short-term and long-term effect of using ABO compatible donors in the era of lung allocation score is unknown. This study determined if carefully selected ABO compatible donors could be used in double lung transplantation (DLT) with good outcomes.

Methods: The United Network for Organ Sharing database was retrospectively reviewed for adult DLT from May 2005 to December 2011.

"Permissive hypoventilation" in a swine model of hemorrhagic shock.

Background: Many penetrating trauma patients in severe hemorrhagic shock receive positive pressure ventilation (PPV) upon transport to definitive care, either by intubation (INT) or bag-valve mask (BVM). Using a swine hemorrhagic shock model that simulates penetrating trauma, we proposed that severely injured patients may have better outcomes with "permissive hypoventilation," where manual breaths are not given and oxygen is administrated passively via face mask (FM). We hypothesized that PPV has harmful physiologic effects in severe low-flow states and that permissive hypoventilation would result in better outcomes.

Single-lung transplantation with ABO-compatible donors results in excellent outcomes.

Background: The goal of this study was to determine if carefully selected ABO-compatible donors in single-lung transplantation results in acceptable outcomes.

Methods: The United Network for Organ Sharing database was reviewed for adult single-lung transplant recipients from May 2005 to December 2011. Recipients of lungs from ABO-compatible donors were compared with those of ABO-identical donors.

Continuous flow left ventricular assist device technology has influenced wait times and affected donor allocation in cardiac transplantation.

Objective: Bridge to transplantation patients with continuous flow left ventricular assist devices (cfLVADs) are assigned United Network for Organ Sharing status 1A or 1B priority while awaiting orthotopic heart transplantation. We investigated the influence of cfLVAD on the waitlist times and organ allocation.

Methods: The United Network for Organ Sharing database was examined from 2005 to 2012 for patients with cfLVAD and pulsatile flow LVAD (pLVAD).

Prehospital intubation does not decrease complications in the penetrating trauma patient.

Intubation in the prehospital setting does not result in a survival benefit in penetrating trauma. However, the effect of prehospital intubation (PHI) on the development of in-hospital complications has yet to be determined. The goal of this study was to determine if PHI in patients with penetrating trauma results in reduced mortality and in-hospital complications.

Surgical management of tricuspid valve endocarditis in systemically infected patients.

Background And Aim Of The Study: Isolated bacterial tricuspid valve (TV) endocarditis is usually managed medically. Whilst the indications and optimal timing for surgical treatment of the condition have not been clearly defined, it is hypothesized that early surgery in patients who are bacteremic and/or have evidence of systemic seeding is superior to medical treatment.

Methods: All cases of isolated TV endocarditis reported between 2006 and 2011 at the authors' institution were reviewed.
