The increasing use of arm totally implantable vascular access devices for breast cancer patients who require chemotherapy has led to a greater risk of complications and failures and, in particular, to upper extremity deep vein thrombosis. This study aims to investigate the outcomes of the arm peripherally inserted central catheter-PORT technique in breast cancer patients. ⋯ The peripherally inserted central catheter-PORT is a safe vascular device for chemotherapy delivery that achieves similar clinical results as traditional long-term vascular access devices (peripherally inserted central catheter and arm totally implantable vascular access device, in particular) in breast cancer patients.

Catheter-related bloodstream infections caused by Staphylococcus aureus represent one of the most fearful infections in chronic haemodialysis patients with tunnelled central venous catheters. Current guidelines suggest prompt catheter removal in patients with positive blood cultures for S. aureus. This manoeuvre requires inserting a new catheter into the same vein or another one and is not without its risks. ⋯ Our data lead us to believe that it is possible to successfully treat catheter-related bloodstream infection caused by S. aureus and to avoid removing the tunnelled central venous catheter in many more cases than what has been reported in the literature. On the third day, it is mandatory to decide whether to replace the tunnelled central venous catheter or to carry on with antibiotic therapy. Apyrexia and amelioration of laboratory parameters suggest continuing systemic and antibiotic lock therapy for no less than 4 weeks, otherwise, tunnelled central venous catheter removal is recommended.

Arteriovenous fistula is the most preferred form of vascular access, but stenosis treated by balloon angioplasty is prone to restenosis. Multiple trials have been published with regard to the use of paclitaxel-coated balloon to prolong lesion patency compared to conventional balloon. Although paclitaxel-coated balloon has theoretical appeal, its use has not been widespread nationwide due to cost and lack of large-scale multicenter studies. We performed this meta-analysis to evaluate whether paclitaxel-coated balloon outperforms conventional balloon to prolong target lesion patency. ⋯ Paclitaxel-coated balloon showed no statistically significant improvement over conventional balloons in decreasing fistula stenosis in randomized controlled trial but were significant for cohort studies.

Peripherally inserted central catheter tip migration is an infrequent event that occurs in neonatal, pediatric, and adult patients. We discuss a novel technique of utilizing intracavitary electrocardiogram to help confirm proper peripherally inserted central catheter tip repositioning, thereby reducing the need for serial radiographs. ⋯ Several techniques have been published on methods to reposition a migrated peripherally inserted central catheter tip back to the superior vena cava/right atrial junction. These repositioning techniques often require fluoroscopic guidance or a confirmatory radiograph to assess the appropriate peripherally inserted central catheter tip location. At times, several radiographs may be required before the tip is successfully repositioned. This novel application of intracavitary electrocardiogram can help to minimize radiographs when peripherally inserted central catheter tip repositioning is required.

Randomized Controlled Trial Comparative Study
Sonographic visualization and cannulation of the axillary vein in two arm positions during mechanical ventilation: A randomized trial.
Abduction of the arm has been used for ultrasound-guided infraclavicular axillary vein cannulation. We evaluated the influence of arm position on sonographic visualization and cannulation of the axillary vein in patients receiving mechanical ventilation. ⋯ Abducted position moved the clavicle cephalad and allowed sonographic visualization of infraclavicular axillary vein approximately 2 cm more proximally than with the adducted arm, with a comparable rate of cannulation success.
