Introduction and objectives: the introduction of a j-tip guidewire, through the puncture needle or a catheter, can be tricky. Normally, both hands are needed. The J-straightener or introducer does not simplify the technique much: Also, both hands are needed; otherwise, the guidewire have to be placed in the J-straightener before beginning the procedure or by the help during the procedure. The guidewire might slip from the J-straightener or the introducer might fall complicating more this simple procedure.
We present our experience of a simple trick to facilitate the introduction of a J-tip guidewire without using the J-straightener.
Materials and methods:
We present a straightening technique that can be performed single handedly. A J-tip Tefon guidewire is firmly held between index and thumb, a few centimeters below the tip. Simultaneously, the other fingers of the same hand do traction on the body of the guidwire against the palm of the hand. Thus, the tip is straightened.
Results: the technique is possible single handedly, and allows the introduction of the guidewire without letting-go of the puncture-needle. It is much quicker and sure than using a J-straightner.
A guidewire is composed of wire wounded around a steel core. Traction on the body of the guidewire, while firmly holding the guidewire near the tip, will lead to a tightening of the wounded wire in the tip, which will lead to the straightening of the j-tip.
However, this technique is possible only with a Teflon guidewire and not with a hydrophilic guidewire.
Conclusion: the straightening of a J-tip Teflon guidewire is possible single handedly, and without the use of a J-straightener. This technique simplifies and facilitates the introduction of a J-tip guidewire.
