Comparative Study
Clinical use of Sherlock-3CG® for positioning peripherally inserted central catheters.
Intracavitary electrocardiogram technique is recognized as a safe, accurate, and inexpensive method for verifying the tip location of central venous access devices. While the technique can be carried out with any standard electrocardiogram monitor, dedicated electrocardiogram monitors specifically designed for the intracavitary electrocardiogram are also available. One of these dedicated monitors is Sherlock-3CG®, characterized by the integration of a magnetic-based tip navigation method with an electrocardiogram-based tip location method. ⋯ Our study could not demonstrate any specific advantage of Sherlock-3CG either as a magnetic-based tip navigation method or as an electrocardiogram-based tip location method.

Aneurysm of autogenous arteriovenous fistula is a common complication in patients receiving hemodialysis. We present a novel method for repair of a case of aneurysm of arteriovenous fistula resulting from stenosis. A 52-year-old woman presented with aneurysm formation of the left upper arm arteriovenous fistula, with related numbness in the left hand. ⋯ After surgery, the remodeled arteriovenous fistula was immediately usable for hemodialysis with normal arteriovenous fistula flow in the upper arm. The repair technique achieved not only aneurysmorrhaphy but also created an autologous vascular graft as the bypass after removal of the narrowed segment. Moreover, this technique achieved reduced arterial inflow and is suitable for patients with conditions similar to those of this case.

Randomized Controlled Trial
The effect of stellate ganglion block on the function of arteriovenous fistulas for hemodialysis: A randomized trial.
The best access for hemodialysis is an autologous arteriovenous fistula (AVF). The most helpful way for vasodilation in the upper limb is stellate ganglion block. We aim to evaluate the effect of stellate ganglion block on outcome of vascular access for dialysis. ⋯ Stellate ganglion block before arteriovenous fistula surgery in the upper limbs improves hemodialysis success rate.
