conclusions the cannulation of the central vein in neonates and children in a skilled hand would be performed with great success rate and low complications. results there were 1340 newborn patients (first 28 days of life) in our study population. in these newborns, only 55 cannulations failed; one patient was complicated with pneumothorax; guide wires malfunctioned in 21 cases; and first- attem...

Vertebral artery cannulation is an unusual complication during internal jugular vein cannulation. We report a case of vertebral artery cannulation, which occurred during an attempt to cannulate the right internal jugular vein, and we discuss the management of such a rare complication.

BACKGROUND In cases of difficult bile duct cannulation, the use of wire-guided cannulation over a pancreatic stent (WGC-PS) or the double guidewire technique (DGT) may facilitate biliary cannulation. The aim of this study was to compare the outcomes of WGC-PS and DGT in patients with difficult biliary cannulation. METHODS We conducted a retrospective cohort study of all endoscopic retrograde ...

Retinal vein cannulation is a technically demanding surgical procedure where therapeutic agents are injected into the retinal veins to treat occlusions. The clinical feasibility of this approach has been largely limited by the technical challenges associated with performing the procedure. Among the challenges to successful vein cannulation are identifying the moment of venous puncture, achievin...

BACKGROUND The standard technique for fistula cannulation, the rope-ladder technique, is problematic for patients with short fistula lengths and for patients in whom the fistula is difficult to cannulate. The buttonhole technique, cannulation of exactly the same site, offers the advantage of an easy cannulation procedure. However, it can be used only in native fistulas and cannulation is prefer...

BACKGROUND Success in deep biliary cannulation via native ampullae of Vater is an accepted measure of competence in ERCP training and practice, yet prior studies focused on predicting adverse events alone, rather than success. Our aim is to determine factors associated with deep biliary cannulation success, with/ without precut sphincterotomy. METHODS The ERCP Quality Network is a unique pros...

PURPOSE Many individuals with end-stage renal disease (ESRD) have adequate arteries and veins for construction of an arteriovenous fistula (AVF) but the fistula may be too deep to cannulate because of overlying adipose tissue. This study evaluated the safety and efficacy of liposuction to superficialize deep AVFs. METHODS Between September 2009 and January 2011, 13 patients participated in th...

BACKGROUND We combined transapical cannulation and right axillary artery cannulation in the repair of acute type A aortic dissection in order to reduce mortality and morbidity in the presence of risk of malperfusion. Early and midterm outcomes were evaluated. METHODS Between October 2009 and March 2012, 23 aortic dissection patients (age, 54.3 ± 13.5 years) received graft replacement using a ...

The use of extracorporeal membrane oxygenation (ECMO) has increased over recent years providing respiratory and cardiac support. Optimal cannula placement is essential for successful patient outcomes. Multiple cannulation strategies may be employed depending on the age/weight of the patient and their underlying condition. This article discusses cannulation technique focusing on the cannulation ...

Methods Prospective 6 months pre-post study of all CVC cannulations, except those peripherally inserted, in patients from onco-haematological ward in a university teaching hospital. Ultrasound team was composed by 3 physicians and 2 nurses trained on vascular USG cannulation. During “pre-team” period, CVC cannulation was performed by the intensivist on duty using anatomical landmark or USG tech...
