Results 52 year old woman addicted to parenteral drugs, stage C3 HIV with 2 weeks duration fever. On arrival had malaise, hypotensive, febrile, tachycardic... it was not possible to catheterize a peripheral vein we performed a central line cannulation: ultrasound-guided infraclavicular axillary vein. Less arterio-venous overlap and a greater distance between artery and vein and from vein to rib...

OBJECTIVE To find out the feasibility of hysteroscopic tubal cannulation in proximal tubal obstruction and the incidence of pregnancy following achievement of tubal patency. METHODS Hysteroscopic tubal cannulation was performed along with concomitant laparoscopy in 24 cases (age 23 to 35 years) of proximal tubal obstruction between January 2000 and December 2002. Successful cases were followed ...

Various endoscopic techniques have been developed to overcome the difficulties in biliary or pancreatic access during endoscopic retrograde cholangiopancreatography, according to the preference of the endoscopist or the aim of the procedures. In terms of endoscopic methods, guidewire-assisted cannulation is a commonly used and well-known initial cannulation technique, or an alternative in cases...

INTRODUCTION Central venous cannulation is crucial in the management of the critical care patient. This study was designed to evaluate whether real-time ultrasound-guided cannulation of the internal jugular vein is superior to the standard landmark method. METHODS In this randomised study, 450 critical care patients who underwent real-time ultrasound-guided cannulation of the internal jugular...

STUDY OBJECTIVE The objective of this study was to demonstrate the safety and utility of a method of percutaneous access for cannulation of adult patients for venovenous extracorporeal life support (ECLS). DESIGN A retrospective review of a patient series. SETTING A surgical ICU at a university teaching hospital. PATIENTS The study group consisted of 94 adults > 17 years old with respirat...

BACKGROUND Extensive type A aortic dissections that involve peripheral great vessels can complicate the choice of a cannulation site for cardiopulmonary bypass. We started to employ direct cannulation of the true lumen on the concavity of the aortic arch by Seldinger technique and evaluated the efficacy of this access technique as an alternative arterial inflow target in aortic surgery. MATER...

BACKGROUND Real-time ultrasound (US) in central venous catheterization is superior to pre-procedure US. However, moving real-time US into routine practice is impeded by its perceived expense and difficulty. Currently, pre-procedure US and landmark (LM) methods are most widely used. We investigated these techniques in internal jugular vein (IJV) catheterization in respect of operator experience,...

BACKGROUND The buttonhole technique is an alternative method of cannulating the arteriovenous fistula (AVF) in hemodialysis (HD), frequently used for home HD patients. However, the balance of risks and benefits of the buttonhole compared with the rope-ladder technique is uncertain. STUDY DESIGN A systematic review of randomized trials and observational studies (case reports, case series, stud...

BACKGROUND Timing of first cannulation of an arteriovenous graft has been the subject of great debate for clinicians worldwide. In this paper, we reviewed the current literature on the timing of first cannulation of arteriovenous grafts. METHODS Searches of PubMed, Medline and the Cochrane Library were performed using specific search terms to identify articles, dealing primarily with the timi...

PURPOSE To propose a simulation-based ultrasound-guided central venous cannulation skills' training program, during residency. METHODS This study describes the strategies for learning the ultrasound-guided central venous cannulation on low-fidelity bench models. The preparation of bench models, educational goals, processes of skill acquisition, feedback and evaluation methods were also outlin...
