Patients with severe accidental hypothermia require active rewarming. External rewarming may not be successful in severe hypothermia, and use of invasive techniques is limited to regional centers and is associated with vascular access site and other complications. We present a patient with severe accidental hypothermia who was successfuly rewarmed using a novel esophageal heat transfer device. A 55-year-old male (175 cm, 71 kg) was admitted with the first recorded temperature 23.3°C. Rewarming using renal replacement therapy circuit was unsuccessful because of severe hypotension...

BACKGROUND: Transradial access (TRA) in percutaneous coronary intervention (PCI) is a widely used standard technique with lower complication rates compared to transfemoral access (TFA). The aim of this study was to evaluate the impact of TRA versus TFA for PCI on clinically significant vascular access complications in the setting of acute myocardial infarction (AMI). METHODS: This multicenter study randomly assigned 250 patients in a 1:1 fashion (TRA vs. TFA) admitted with or without ST-segment elevation AMI undergoing immediate PCI...

Subcutaneous tissue is a promising site for islet transplantation, due to its large area and accessibility, which allows minimally invasive procedures for transplantation, graft monitoring, and removal of malignancies as needed. However, relative to the conventional intrahepatic transplantation site, the subcutaneous site requires a large number of islets to achieve engraftment success and diabetes reversal, due to hypoxia and low vascularity. We report that the efficiency of subcutaneous islet transplantation in a Lewis rat model is significantly improved by treating recipients with inhaled 50% oxygen, in conjunction with prevascularization of the graft bed by agarose-bFGF...

Background/Aims: Transradial intervention (TRI) is becoming the preferred method over transfemoral intervention (TFI) because TRI is associated with lower incidence of major bleeding and vascular complications. However, there has been limited published data regarding the clinical outcomes of TRI versus TFI in Korean patients with ST-elevation myocardial infarction (STEMI). Methods: A total of 689 consecutive STEMI patients who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) from January to December of 2009 at nine university hospitals were enrolled in this study...

An arteriovenous graft (AVG) has a higher patency rate in stenosis progression at the venous anastomosis site, which causes coexisting inflow and outflow stenoses. This leads to increases in blood pressure, flow velocity, and flow resistance, resulting in hemodialysis (HD) vascular access dysfunction from early clots and thrombosis to the progression of coexisting stenoses. To prevent vascular access complications such as inflow or outflow stenoses, this study proposes a novel examination method in an experimental AVG system using a substitution-rate based screening model...

PURPOSE: Intraosseous (IO) vascular access has been used since the Second World War and is warranted when there is an emergency and/or urgent need to replenish the vascular pool. Despite long-term and satisfactory results from delivering large quantities of intravenous fluid via the medullary space of bone, use of this space for a distant receptacle for cerebrospinal fluid (CSF) diversion has seldom been considered. METHODS: The current paper reviews the literature regarding the bony medullary space as a receptacle for intravenous fluid and CSF...

The radiocephalic arteriovenous fistula (AVF) provides optimal vascular access for hemodialysis; it has a higher long-term patency rate and fewer complications than other vascular access methods. However, the AVF has a high primary failure rate. The presence of small-diameter vessels at anastomosis sites is an important risk factor for AVF failure. However, in a recent study, despite selecting an adequate artery and vein for creating an AVF by routine preoperative vascular mapping, AVF maturation and primary failure occurred...

Endothelial cells (ECs) are the fundamental building blocks of the vascular architecture and mediate vascular growth and remodeling to ensure proper vessel development and homeostasis. However, studies on endothelial lineage hierarchy remain elusive due to the lack of tools to gain access as well as to directly evaluate their behavior in vivo. To address this shortcoming, a new tissue model to study angiogenesis using the mammary fat pad has been developed. The mammary gland develops mostly in the postnatal stages, including puberty and pregnancy, during which robust epithelium proliferation is accompanied by extensive vascular remodeling...

Extensive de novo vascularization of leafy galls emerging upon Rhodococcus fascians infection is achieved by fascicular/interfascicular cambium activity and transdifferentiation of parenchyma cells correlated with increased auxin signaling. A leafy gall consisting of fully developed yet growth-inhibited shoots, induced by the actinomycete Rhodococcus fascians, differs in structure compared to the callus-like galls induced by other bacteria. To get insight into the vascular development accompanying the emergence of the leafy gall, the anatomy of infected axillary regions of the inflorescence stem of wild-type Arabidopsis thaliana accession Col-0 plants and the auxin response in pDR5:GUS-tagged plants were followed in time...

Individuals suffering from chronic kidney disease (CKD) deal with major morbidity and mortality including poor exercise tolerance. A variety of factors including anemia, poor muscle mass, cardiovascular changes and limited physical activity contribute to exercise intolerance. Studies suggest that early initiation of aerobic and resistance training improves the muscle function, ability to tolerate exercise and quality of life in CKD patients. A thorough medical examination and exercise testing are recommended before initiating an exercise regimen in individuals with CKD...

INTRODUCTION AND PURPOSE: The increasing number of patients undergoing hemodialysis and the limited number of access sites have resulted in an increasing number of techniques to maintain vascular access for hemodialysis. Thrombosed arteriovenous (AV) fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definitive AV access loss. The purpose of this study was to review the feasibility and initial results of this novel endovascular treatment of thrombosed AV fistulas with large venous aneurysms...

Maintaining vascular access patency represents a tremendous challenge in hemodialysis patients. Although "native" arteriovenous fistula (AVF) is currently recommended as primary vascular access, neointimal hyperplasia stenoses frequently develop, with a risk for AVF thrombosis and vascular access loss. For years, first-line treatment of AVFs stenoses has been percutaneous transluminal angioplasty, generally with high-pressure or cutting uncoated balloons. However, restenosis and reintervention rates remain incredibly high and occur, according to recent studies, in up to 60% and 70% of patients at 6 and 12 months, respectively...

A cornerstone of hemodialysis treatment is the creation of a functional and durable dialysis vascular access. Every patient with chronic kidney disease should have a plan of renal replacement therapy and access site protection. Factors having a crucial impact on vascular access selection include age, comorbidity, vessel quality, prognosis, dialysis urgency, and surgeon's preferences. Our medical group have reviewed these factors in our patients and, based on recently published data, developed a clinical decision tree for dialysis access in the chronic kidney disease patient...

INTRODUCTION: The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or "atypical" approach, first described by Pittiruti. MATERIALS AND METHODS: We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area ("atypical" PICC insertion) and then tunneled on the chest...
