BACKGROUND: It remains unclear whether radial increases the risk of operator or patient radiation exposure when performed by expert operators OBJECTIVES: To determine whether radial access increases radiation exposure METHODS: We randomly assigned 8404 patients, with or without ST-segment elevation acute coronary syndrome, to radial or femoral access for coronary angiography and percutaneous intervention, and collected fluoroscopy time and dose area product (DAP). In the radiation sub-study (RAD-MATRIX), we anticipated that 13 or more operators, each wearing a thorax (primary endpoint), wrist and head (secondary endpoints) lithium fluoride thermo luminescent dosimeter and randomizing at least 13 patients per access site were needed to establish non-inferiority of radial versus femoral access...

Introduction Thoracic outlet syndrome (TOS) is one of the most extensively discussed diagnoses. There is neither a clear and homogenous clinical presentation nor an accepted definition. The term describes a complex of symptoms and complaints caused by the compression of nerves and vascular structures at one of the three defined constrictions of the upper thoracic aperture. Methods Based on a comprehensive literature review, this article presents the etiology, epidemiology and clinical diagnostics as well as the possibilities and outcomes of surgical treatment...

BACKGROUND: Percutaneous endovascular aneurysm repair (PEVAR) has been increasingly employed in the endovascular treatment of abdominal aortic aneurysms. Furthermore, the percutaneous approach can be used with minimal sedation and local anesthesia in the majority of cases. The purpose of this study is to assess the safety and effectiveness of a "percutaneous first" approach to femoral access for EVAR. METHOD: From 2012 to 2014, PEVAR has been the preferred approach to femoral access for EVAR at our institution...

Swing-segment lesions are a fairly common reason for access failure and predispose to repeated interventions. The pathophysiology, hemodynamic circumstances and the primary intervention might all play a role in early recurrence. Mainly, percutaneous transluminal angioplasty (PTA), bare metal stenting and stent graft implantation have been performed to prolong lesion patency and access circuit patency. The available data on endovascular treatment of swing-segment lesions are scarce, heterogeneous and of poor quality...

Complications related to percutaneous biliary tract interventions (PBTIs) can range from access site discomfort to life-threatening vascular complications. These complications are relatively uncommon, and most of them are self-limiting. However, major complications for which an increased level of patient care and/or a prolonged hospital stay are required and that may lead to death-albeit rarely-can occur. Some of the most common complications related to PBTI include pain, infection, bile leakage, and catheter blockage...

Problems related to hemodialysis access are a significant cause of morbidity and mortality in patients with end-stage renal disease. Physicians of all specialties who are involved in the placement and maintenance of vascular access for hemodialysis must have a long-term strategy for sequential placement of autogenous fistulas, transpositions, and prosthetic grafts to preserve access sites and to avoid long-term use of tunneled dialysis catheters. The Fistula First and KDOQI initiatives have provided strategies and algorithms for access placement in patients with chronic kidney disease...

We previously analyzed the Fab-1:VEGF (vascular endothelial growth factor) system described in this work, with both native top-down mass spectrometry and bottom-up mass spectrometry (carboxyl-group or GEE footprinting) techniques. This work continues bottom-up mass spectrometry analysis using a fast photochemical oxidation of proteins (FPOP) platform to map the solution binding interface of VEGF and a fragment antigen binding region of an antibody (Fab-1). In this study, we use FPOP to compare the changes in solvent accessibility by quantitating the extent of oxidative modification in the unbound versus bound states...

Success of cell therapy in avascular sites will depend on providing sufficient blood supply to transplanted tissues. A popular strategy of providing blood supply is to embed cells within a functionalized hydrogel implanted within the host to stimulate neovascularization. However, hydrogel systems are not always amenable for removal post-transplantation; thus, it may be advantageous to implant a device that contains cells while also providing access to the circulation so retrieval is possible. Here we investigate one instance of providing access to a vessel network, a thin sheet with through-cut slits, and determine if it can be vascularized from autologous materials...

BACKGROUND: Surgical site infections (SSI) represent a significant public health problem as the most common nosocomial infection and a leading cause of unplanned hospital readmissions among surgical patients. Many develop following hospital discharge and often go unrecognized by patients. Telemedicine offers the opportunity to leverage the mobile technology to remotely monitor wound recovery in the transitional period between hospital discharge and routine clinic follow-up. However, many existing telemedicine platforms are episodic, replacing routine follow-up, rather than equipped for continued monitoring; they include only low-risk patient populations and those who already have access to and comfort with the necessary technology; and transmit no visual information...

BACKGROUND: Optimising filter life and performance efficiency in continuous renal replacement therapy has been a focus of considerable recent research. Larger high quality studies have predominantly focussed on optimal anticoagulation however CRRT is complex and filter life is also affected by vascular access, circuit and management factors. We performed a systematic search of the literature to identify and quantify the effect of vascular access, circuit and patient factors that affect filter life and presented the results as a meta-analysis...

It is well known that the number of patients requiring a vascular grafts for use as vessel replacement in cardiovascular diseases, or as vascular access site for hemodialysis is ever increasing. The development of tissue engineered blood vessels (TEBV's) is a promising method to meet this increasing demand vascular grafts, without having to rely on poorly performing synthetic options such as polytetrafluoroethylene (PTFE) or Dacron. The generation of in vivo TEBV's involves utilizing the host reaction to an implanted biomaterial for the generation of completely autologous tissues...
