All types of vascular access, a necessity for haemodialysis, are prone to thrombosis and if untreated this results in failure. Thrombosis results from the combination of impaired blood flow, endothelial and vessel wall injury and a propensity towards pro-coagulative states, either intrinsic or aggravated by dialysis or dehydration. The treatment of access thrombosis relies on removal of the clot (thrombectomy) and treatment of the underlying problem. In most cases this is stenosis secondary to neointimal hyperplasia which can occur early (failure to mature) or later...

Congenital coronary artery fistula is an uncommon anomaly. Transcatheter coil embolization or Amplatzer vascular plug device closure of fistula is often done in symptomatic patients with safe accessibility to the feeding coronary artery. Embolization of Amplatzer vascular plug device is rare. We report an 11-year-old male child who presented to us with increasing shortness of breath for 7 years. He had a history of Amplatzer vascular plug device closure of right coronary-cameral fistula 8 years back. Echocardiography demonstrated a dilated aneurysmal right coronary artery with turbulent jet entering into the right ventricle (RV) and device embolized into the left pulmonary artery (LPA)...

There is a range of risk factors that can lead to peripheral intravenous (IV) cannula failure, and several failed cannulation attempts can result in the patient experiencing increased pain, discomfort and delays in receiving IV therapy. The Vessel Health and Preservation (VHP) framework is a tool that can be used to improve clinical decision-making and the patient experience in relation to vascular access and IV therapy. Use of the VHP framework can ensure the right vein and right vascular access device (VAD) is selected at the right time for each patient...

BACKGROUND: We investigated the application and feasibility of a novel software tool designed for the visualization of the aortic root during transcatheter aortic valve implantation (TAVI). The final positioning of the device prior deployment remains the most critical phase during TAVI. METHODS: Philips "Vascular Outlining" prototype application was used during balloon expandable Edwards Lifesciences SapienXT valve deployment. It processes any angiographic sequences, extracting the static outline of vessels and projecting the two- dimensional vessel margins as a roadmap on live fluoroscopy...

Transcatheter aortic valve implantation (TAVI) has become a widely accepted strategy for the treatment of aortic stenosis in patients at intermediate, high, or prohibitive surgical risk. After >1 decade of innovation and clinical trial experience, the available technology for TAVI has grown enormously, and now includes a myriad of vascular access approaches and innovative valve designs. As a result, the range of patients who can benefit from these advances continues to grow rapidly. Furthermore, given the improved safety profile and clinical success of current-generation devices in randomized trials, the use of TAVI among even low-risk populations is justified in current trials...

We report the case of a catheter-related bloodstream infection caused by Chryseobacterium indologenes, an uncommon and multi-resistant pathogen, in a pediatric patient with a long-term vascular access device placed for chemotherapy treatment. The infection was successfully treated with ciprofloxacin antibiotic-lock therapy. This is the first report on successful salvage of a long-term device colonized by multi-resistant Chryseobacterium indologenes.

Arteriotomy closure devices (ACDs) are routinely used for vascular closure during invasive cardiovascular procedures. They decrease time to hemostasis as well as length of stay. Major complications such as arterial ischemia and occlusion can be encountered in a minority of patients. We are describing a series of 3 patients with access site closure using Angio-Seal after coronary angiography who developed intermittent claudication within 2-3 weeks of follow-up. Access site thrombosis/stenosis in the CFA was found in all the three cases...

BACKGROUND: Peripheral Intravenous cannula (IV) is the most common vascular access device used to administer medications with the exception of medication or fluid with high or low PH or hyperosmolarity which may cause severe damage to small veins. The insertion of a peripheral intravenous cannula in newborn infants can be difficult. Appropriate veins with sufficient capacity to insert a cannula become less available throughout the hospital stay. Once a peripheral intravenous cannula is inserted, it is desirable that its patency can be maintained as long as possible...
