BACKGROUND AND PURPOSE Routine carotid sonography and MR angiography cannot reliably detect the markedly reduced flow velocities associated with very severe carotid stenosis. In this study, we sought to evaluate the accuracy of single row detector helical CT angiography in distinguishing hairline residual lumen from total occlusion of severely stenosed internal carotid arteries (ICAs). METHOD...

Internal jugular vein has been recommended as the vascular access for haemodialysis because it is associated with less thrombotic/stenotic complication. Despite this recommendation, subclavian vein access is still being frequently used. This paper aims at reviewing the rate of complications associated with temporary double lumen subclavian vein dialysis access catheter in a personal series. It ...

For the management of severe haemoptysis we have developed a double-lumen, bronchus-blocking catheter that can be introduced through the working channel of a standard fibrebronchoscope. We wondered whether this catheter would be suitable to control pulmonary haemorrhage in clinical practice. Over a period of 36 months, 30 of these catheters were used in 27 patients with moderate and massive pul...

The common complications of flow-directed pulmonary artery catheters are well documented,1 aand include thrombosis on the catheter surface after prolonged use.3' Because of the high cost of these catheters (three lumen £30, four lumen thermodilution £80) it is tempting to reuse them once after sterilising with ethylene oxide, despite the manufacturer's recommendation to the contrary. We report ...

The coronary sinus (CS) catheter, which provides left atrial and ventricular potentials also serves as an anatomical marker, is indispensable in modern EPS. However, inserting CS catheters can sometimes be challenging due to anomalies or the presence of (LV) leads. In this context, Okada et al. demonstrated usefulness novel over-the-wire 2.7-Fr microcatheter (EPstar Fix AIV; Japan Lifeline), ha...

There was no pericardial effusion. Abdominal ultra-sonography revealed bilateral normal size kidneys with plications, lymphatic injury, lymph leak increased echogenicity. The patient was started on maintenance haemodia-lysis. A double lumen haemodialysis catheter was

In vivo, the position of the conductance catheter to measure vessel lumen cross-sectional area may vary depending on where the conductance catheter is deployed in the complex anatomical geometry of arteries, including branches, bifurcations, or curvatures. The objective here is to determine how such geometric variations affect the cross-sectional area (CSA) estimates obtained using the cylindri...

Results: 73.86% of the patients had central venous access in the subclavian vein, 100% used double lumen Catheter related Blood stream infections, 0.5% chlorhexidine solution for skin antisepsis, dressing coverage is performed mostly with Sterile gauze and tape, with a daily exchange. The rate of infection related to the use of the Catheter related Blood stream infections was (6.81%). The most ...

CAN J ANESTH 54: 1 www.cja-jca.org January, 2007 by some authors that the tip of the cannula should be withdrawn outside the lumen of the vein and sited subcutaneously to avoid the rare complication of air embolism.4 It has also been suggested that this method will protect the catheter from kinking. The circumstances of this case challenge that assumption, and suggest that it may be preferable ...

The number of indications for lung collapse during different procedures is rising. Difficult upper airway is more often encountered with the need for single lung ventilation. In patients with difficult airway, the safest approach is by placing a single-lumen endotracheal tube with the aid of a flexible fiberoptic bronchoscope. Lung isolation in these patients is then achieved by means of a bron...
