BACKGROUND: The external iliac vein is the standard site used for venous anastomosis in kidney transplantation. When a pre-transplantation diagnosis of iliocaval thrombosis is established, a different and suitable venous drainage for the renal outflow must be identified for successful transplant. METHODS: We report 4 cases of kidney transplantation, performed from 2004 to 2016, in recipients presenting with thrombosis of the inferior vena cava and iliac system needing, because of the lack of access for dialysis, urgent kidney transplantations...

INTRODUCTION: Laryngomalacia is the most prevalent cause of congenital stridor. Flexible laryngobronchoscopy (FLB) is the gold standard for diagnosis. However, FLB requires venous access, deep sedation or general anesthesia, and is associated with patient's and parental discomfort and a considerable cost. Laryngeal ultrasound (LUS) has been shown to provide good evaluation of the normal anatomy and the dynamic motion of laryngeal structures. We investigated the yield of LUS in the diagnosis of laryngomalacia in infants with congenital stridor compared to FLB...

Background: The modality by which haemodialysis (HD) is delivered [arteriovenous fistula (AVF), arteriovenous graft (AVG) or central venous catheter (CVC)] varies widely and is influenced by clinical evidence, patient factors and the prevailing service configuration. The aim of this study was to determine the outcome and impact of access strategy on patient outcome by mapping out the HD journey in a cohort of incident patients. Methods: A 2-year cohort of consecutive incident HD patients from the point of referral for first dialysis access to completion of the first 365 days of HD was prospectively reviewed...

PURPOSE: Central venous access in children, in particular small children and infants, is challenging. We have developed a technique employing adult peripherally inserted central venous catheters (PICCs) as tunnelled central venous catheters (TCVCs) in children. The principal advantage of this novel technique is that the removal technique is less complex than that of conventional cuffed TCVCs. The catheter can be removed simply by being pulled out and does not require general anaesthesia...

PURPOSE: The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be placed to maintain IV access. These catheters are associated with risks including central line-associated bloodstream infection. METHODS: We evaluated the effectiveness and acceptability of an ultrasound-guided peripheral IV service to reduce the number of newly placed central venous catheters on an inpatient ward...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to look for secondary signs of arterialization of the veins, which can suggest a diagnosis of an arteriovenous fistula. However, the accuracy and diagnostic quality of duplex scanning in the diagnostics of a congenital or spontaneous arteriovenous fistula of the head and neck area in adults have been poorly described in the literature...

The correct choice of intra vascular access in critically ill neonates should be individualized depending on the type and duration of therapy, gestational and chronological age, weight and/or size, diagnosis, clinical status, and venous system patency. Accordingly, there is an ongoing demand for optimization of catheterization. Recently, the use of ultrasound (US)-guided cannulation of the subclavian vein (SCV) has been described in children and neonates. This article gives an overview of the current use of US for achieving central venous catheter placement in the SCV or the brachiocephalic vein (BCV) in neonates...
