To develop tissue-engineered arteries (TEAs) with collateral arteries(CAs) in ischemic hind limb goat models(IHLMs). The IHLMs created by removing femoral arteries were divided into non-treated control group(NG); non-catheter group (NCG) in which TEA was anastomosed to external iliac artery(EIA), and surrounded with collagen sponge containing autologous MSCs and VEGF-gelatin microspheres, the distal end of TEA was ligated; catheter group(CG) which received the same procedure as NCG, also received heparin infusion through catheter in EIA...

There has been increasing use of a novel combined femoral venous sheath, catheter and retrievable self-expanding and collapsible diamond-shaped IVC filter (Angel® Catheter, BiO2 Medical), in severely injured patients who cannot receive anticoagulation. As the filter is not detached from the catheter/sheath, it should be easily retrieved. Outcomes included in large registries demonstrate a high safety profile and a 100% retrieval rate. However, at our institution-a Level 1 major UK trauma centre with 4 years of substantial experience in using this device-we've encountered three cases of device fracture and subsequent complicated retrieval dating from Dec 2016 to March 2017...

Central venous catheters are placed in approximately five million patients annually in the US. The preferred site of insertion is one with fewer risks and easier access. Although the right internal jugular vein is preferred, on occasion, the left internal jugular may have to be accessed. A patient was admitted for septic shock, cerebrovascular accident, and non-ST-segment elevation myocardial infarction. A central venous line was needed for antibiotic and vasopressor administration. Due to trauma from a fall to the right side and previously failed catheterization attempts at the left subclavian and femoral veins, the left internal jugular vein was accessed...

Central venous catheterization can be challenging in patients that had undergone repeated catheter placements. Ultrasound scan may overlook venous stenosis which is better visualized using venography. The use of venography should be considered to assess for venous stenosis or vascular anomalies in individuals with multiple catheterizations or in close proximity to cancer.

BACKGROUND: Despite recent progress in survival times of xenografts in non-human primates, there are no reports of survival beyond 5 days of histologically well-aerated porcine lung grafts in baboons. Here, we report our initial results of pig-to-baboon xeno-lung transplantation (XLTx). METHODS: Eleven baboons received genetically modified porcine left lungs from either GalT-KO alone (n = 3), GalT-KO/humanCD47(hCD47)/hCD55 (n = 3), GalT-KO/hD47/hCD46 (n = 4), or GalT-KO/hCD39/hCD46/hCD55/TBM/EPCR (n = 1) swine...

Alfaxalone is becoming a popular anesthetic for nonmammalian vertebrates, but the physiological effects of its administration remain largely unknown in these taxa. Therefore, the cardiovascular responses to a clinically relevant dose of alfaxalone (10 mg/kg) are reported in the bullfrog ( Lithobates catesbeianus), following intramuscular (IM) and intravascular (IV) administration (via a femoral artery catheter) and compared with an IV dose of propofol, another parenteral GABA (γ-aminobutyric acid) agonist in common veterinary use as an induction agent...

INTRODUCTION: Catheter-directed thrombolysis (CDT) has been shown to be a safe and effective treatment for the management of acute iliofemoral DVT. The potential benefits of this therapy include more rapid resolution of symptoms and possible reduction in the long-term sequelae. Many patients diagnosed with DVT in the inpatient setting have contraindications to lytic therapy, but less is known regarding the suitability of thrombolysis for outpatients diagnosed with acute DVT. We sought to determine the proportion of patients who were candidates for thrombolytic therapy and were referred to a vascular specialist for evaluation...

PURPOSE: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice. METHODS: From January 2014 to March 2017, this approach was used in 17 of 453 (3.75%) cases: 11 cerebral aneurysms (4 ruptured, 7 unruptured), 4 acute occlusions of the large cerebral artery, 1 proximal internal carotid artery (ICA) stenosis, and 1 direct carotid cavernous fistula (CCF)...

OBJECTIVE: Application of extracorporeal membrane oxygenation (ECMO) for life support has been widely used in various fields of resuscitation. When the common femoral artery (CFA) is used during cannulation for ECMO support in adults, it is often complicated by limb ischemia. Placement of distal perfusion catheter (DPC) can reduce the incidence of limb ischemia and increases the likelihood of limb preservation, but selection criteria is uncertain. METHODS: This is a retrospective study...

BACKGROUND: It has been suggested that ethnicity can make a significant difference to the likelihood of thromboembolic stroke related to atrial fibrillation. Ethnic differences have been shown to alter inflammatory and haemostatic factors; however, this may all be confounded by differences in cardiovascular risk factors between different ethnicity. The impact of different ethnicities on the thrombogenic profile is not known. The aim of this study was to investigate differences in markers of inflammation, endothelial function and tissue remodelling between Caucasian and Indian populations with supraventricular tachycardia (SVT)...

Previous reports indicate roles for acid-sensing ion channels (ASICs) in both peripheral and central chemoreception, but the contributions of ASICs to ventilatory drive in conscious, unrestrained animals remain largely unknown. We tested the hypotheses that ASICs contribute to hypoxic- and hypercapnic-ventilatory responses. Blood samples taken from conscious, unrestrained mice chronically instrumented with femoral artery catheters were used to assess arterial O2, CO2, and pH levels during exposure to inspired gas mixtures designed to cause isocapnic hypoxemia or hypercapnia...

Catheter ablation is an effective treatment in patients with symptomatic atrial fibrillation. Complications are infrequent and usually resolve with minimal or no intervention, but active bleeding due to arterial injury during the vascular access can sometimes represent a life-threatening complication. Contrast-enhanced computed tomography is the standard technique to detect active bleeding, but it may not be immediately available. We report a case of iatrogenic hemorrhage after catheter ablation, in which contrast-enhanced ultrasonography played a decisive role in the recognition of active arterial bleeding due to injury to the right common femoral artery...

OBJECTIVE: Plaque erosion is increasing its importance as one of the mechanisms of acute coronary syndromes in this statin era. However, the clinical efficacy of currently used lipid-lowering agents in the prevention of thrombotic complications associated with plaque erosion has not been clarified. Therefore, we examined the therapeutic effects of ezetimibe or rosuvastatin monotherapy on spontaneous atherothrombotic occlusion. APPROACH AND RESULTS: Femoral arteries of Japanese white rabbits, fed a high-cholesterol diet, were injured by balloon catheter, and then angiotensin II was continuously administrated...

Nephrotic syndrome is a well-known risk factor of deep vein thrombosis (DVT). Catheter-related DVT under the setting of nephrotic syndrome may be presented as a more fulminant form, phlegmasia cerulea dolens. Phlegmasia cerulea dolens may lead to severe obstruction of venous drainage of the extremities and presents with compartment syndrome that impairs arterial perfusion. Aggressive management with thrombolysis and/or thrombectomy are considered with simultaneous anticoagulant treatment.

Superior vena cava (SVC) stenosis or thrombosis is a well-known complication of central venous catheterization for endocavitary treatments, hemodialysis, or chemotherapy. In cancer patients, these SVC lesions are often symptomatic due to intimal damage and chemotherapy toxicity. We report our experience with six patients treated between 2007 and 2012 via an endovascular approach (n=5) or a direct surgical approach (n=1). All patients had SVC syndrome with facial edema, headache and upper limb edema. In three cases, the catheter was in place when the clinical symptoms occurred...
