OBJECTIVES For needle insertion and guidewire placement during central venous catheterization, a thin-wall introducer needle technique and a cannula-over-needle technique have been used. This study compared these two techniques regarding the success rates and complications during internal jugular vein catheterization. DESIGN Prospective, randomized, controlled study. SETTING A university-af...

Hemodialysis catheter-related bacteremia is a common clinical problem with several management options. We performed a systematic review and meta-analysis to determine cure proportions with systemic antibiotics, antibiotic lock solution, and guidewire exchange. We searched databases and registries; conference proceedings from relevant medical societies; and article reference lists. Data regardin...

Abstract Algorithms for automated analysis of intravascular ultrasound (IVUS) images can be disturbed by guidewires, which are often encountered when treating bifurcations in percutaneous coronary interventions. Detecting guidewires advance therefore help avoiding potential errors. This task is not trivial, since appear rather small compared to other relevant objects IVUS images. We employed CN...

TECHNIQUE On examination, the external opening is identifi ed and hydrogen peroxide instillation is used to detect an internal opening. The fl exible end of a 0.89mm diameter urological guidewire coated in polytetrafl uoroethylene (Boston Scientifi c, Natick, MA, US) is inserted through the internal opening. Using manual palpation and artery forceps, the guidewire is advanced until it protrudes...

Experiences with invasive cardiac catheterization in low birth weight infants are few. In our clinic, we performed balloon aortic valvuloplasty by antegrade approach in a neonate weighing 1100 g with critical aortic stenosis, patent ductus arteriosus and atrial septal defect. The right femoral vein was accessed with a 4 Fr sheath, and a catheter was placed into the left ventricle from the atria...

Avulsion fractures of the posterior cruciate ligament (PCL) are usually found in pediatric populations. This study investigated which of 2 approaches-posteromedial or direct posterior-enables easier PCL reinsertion. Ten fresh cadavers were studied using direct posterior (10 knees) and posteromedial (10 knees) approaches. In both, a guidewire was inserted into the tibial insertion of the PCL as ...

The acute angulation of Roux-en-Y (R-Y) limb precludes endoscopic access for endoscopic retrograde cholangiopancreatography (ERCP) even using a balloon enteroscopy. Here, we describe a case of successful single balloon enteroscopy (SBE)-assisted ERCP using a rendezvous technique in a patient with sharply angulated R-Y limb in a 79-year-old woman who had bile duct stones. Method. At first, a gui...

coronary artery perforation is a rare, but potentially serious, complication of percutaneous coronary intervention and is associated with a high incidence of death, q-wave myocardial infarction, and emergency coronary bypass surgery. management is different but requires prompt recognition and treatment. we describe a case of coronary perforation only after guidewire removal and also review the ...

Central venous catheter insertion is a commonly performed procedure. This used to administer drugs and fluid, especially in critically ill patients, monitor central pressure. We present case of retained guidewire for 17 months which was found incidentally from the abdominal chest radiograph. retrieved J-tip using four loops retrieval snare. The process complicated with rupture guidewire, causin...

Endoscopy is the first-line therapy for most post-liver transplantation anastomotic biliary strictures. Passage of a guidewire through the stricture is done under fluoroscopic guidance. Although anastomotic biliary strictures are usually short, they can be tight, fibrotic, and angulated, sometimes not allowing guidewire passage. Additional interventions (percutaneous transhepatic cholangiograph...
