Keywords: chest radiograph; haemodialysis catheter; jugular vein and a triple lumen catheter in the right. Four days post-operatively, she developed a fever, pericardial tamponade; central venous cannulation; complications hypotension, a worsening systemic acidosis and olig-uria. Pulmonary artery catheter readings revealed a pulmonary artery wedge pressure of 23 mmHg, pulmonary artery pressure ...

OBJECTIVE To develop a simple and versatile catheter system for complex cardiac catheterisation because angiography and pressure measurements during diagnostic and interventional cardiac catheterisation are often unsatisfactory. METHODS The Multi-Track Angio catheter system is a single lumen side-hole catheter with a short distal extension containing a lumen for a standard guidewire. The cath...

Using catheter-mounted 2-D array transducers, we have obtained real-time 3-D intracardiac ultrasound (US) images. We have constructed several transducers with 64 channels inside a 12 French catheter lumen operating at 5 MHz. The transducer configuration may be side-scanning or beveled, with respect to the long axis of the catheter lumen. We have also included six electrodes to aquire simultaneo...

Aeromonas hydrophila (AH) is an aquatic bacterium. We present a case of fifty-five-year-old gentleman with chronic kidney disease (CKD) due to crescentic IgA nephropathy who presented to us with fever. He was recently pulsed with methyl prednisolone followed by oral prednisolone and discharged on maintenance dialysis through a double lumen dialysis catheter. Blood culture from peripheral vein a...

One of the complications related to central venous catheters is occlusion secondary to thrombus formation within or surrounding the catheter lumen. Historically, methods to prevent these occlusions have included vigorous flushing, coordinated flushing-clamping techniques, and antithrombotic prophylaxis using low-dose warfarin or low molecular weight heparin. Positive displacement devices recent...

An electromagnetic flowmeter incorporated into a catheter is described. The catheter is introduced into the aorta via the femoral artery. The flow sensor is located some distance below the catheter tip and is sensitive to flow at right angles to the catheter. A crater-like elevation at one end of the transducer lumen permits funnel-like connection of the transducer to the ostium of an aortic br...

BACKGROUND A 72 year old male was admitted to the medical intensive care unit with septic shock. CASE PRESENTATION A left subclavian central venous catheter was inserted on the day of admission whose tip was pushing against the wall of the vessel lumen. The patient's condition improved with treatment, but three days later had a new episode of acute hypotension. CT scan of the chest showed tha...

INTRODUCTION Catheter-related infection is associated with increased all-cause mortality and morbidity in hemodialysis patients. This study aimed to evaluate an antimicrobial lock solution (cloxacillin and heparin) in temporary noncuffed double-lumen catheters for long-term intermittent hemodialysis as a method of preventing catheter-related infection. MATERIALS AND METHODS Patients on hemodi...

A prototype ultrasound imaging catheter was evaluated in vitro using 17 human atherosclerotic artery segments before and after balloon dilatation angioplasty. The catheter was 1.2 mm in diameter and incorporated a single 20-MHz ultrasound transducer to obtain cross-sectional images of the arterial lumen. In 15 of the 17 (88%) arteries, high quality images were obtained, which demonstrated clear...

ABSTRACT Objectives: to establish the prevalence of salvage central venous catheters in newborns with bloodstream infection caused by coagulase-negative staphylococci. Methods: retrospective cross-sectional study 136 admitted Neonatal Intensive Care Unit between 2011 and 2017. The total 143 events undergoing antibiotic therapy were evaluated. Results: among events, 39 which was used saved 69 ca...
