BACKGROUND Conventional guidewires are not suitable for use during cardiovascular magnetic resonance (CMR) catheterization. They employ metallic shafts for mechanical performance, but which are conductors subject to radiofrequency (RF) induced heating. To date, non-metallic CMR guidewire designs have provided inadequate mechanical support, trackability, and torquability. We propose a metallic g...

BACKGROUND It has been reported that the direction of the guidewire J-tip is associated with misplacement of a central venous catheter. We hypothesized that real-time ultrasound-guided infraclavicular subclavian venous cannulation would be less influenced by the direction of guidewire J-tip compared to landmark method. METHODS Sixty adult patients who required subclavian venous catheterizatio...

Endoscopic ultrasonography-guided hepaticogastrostomy (EUS-HGS) is used after failed endoscopic retrograde cholangiopancreatography (ERCP) [1]. Manipulation of the guidewire is one of the most challenging techniques in EUSHGS.We present a successful case of rescue guidewire technique using a multilumen catheter [2], namely an uneven double-lumen cannula (Piolax Medical Devices, Yokohama, Kanaga...

The preferred treatment of a type II odontoid fracture is anterior odontoid screw fixation to preserve the cervical spine range of movement. This case report describes an unusual complication of guidewire breakage during anterior odontoid cannulated screw fixation for a 52-year-old patient who presented with a type II odontoid fracture after a motor vehicle accident. The distal segment of the g...

OBJECTIVE A new endovascular tool, the Liungman Guidewire Fixator, has been developed to simplify endovascular treatment in complex aortic aneurysms. The device has been extensively tested in bench models and animal trials. To verify the safety and functionality demonstrated in the porcine model, the device was tested in ten patients undergoing endovascular aortic repair (EVAR) or fenestrated e...

OBJECTIVE To report our technique that helps locate the guidewire into the ureter enabling safe dilatation during PCNL. MATERIALS AND METHODS Cases in which the guidewire failed to pass into the ureter following successful puncture of the desired calyx were subjected to this technique. A second guidewire was passed through the outer sheath of a 9 Fr. metallic dilator cannula, passed over the ...

sheared guidewire following failed endoscopic ultrasound-guided pancreatic duct drainage A 50-year-old man with a retained sheared guidewire in the main pancreatic duct and pancreatic parenchyma was referred for recurrent pancreatitis. He had previously undergone a pancreaticoduodenectomy for pancreatic hemangioma and was experiencing recurrent pancreatitis due to pancreaticojejunostomy strictu...

The Neuroform EZ Stent System is a fourth generation intracranial aneurysm stent that utilizes an integrated navigation guidewire. While designed to facilitate stent delivery, the guidewire can rarely impede proper positioning of the stent. In this technical case report, severing the guidewire from the stent delivery system with surgical scissors was required for successful stent implantation.

We would like to present our experience of nasobiliary tube (NBT) transfer. A description of this technique, called the guidewire maneuver, follows (●" Video 1). The patient changes from the prone to the left lateral decubitus position while continuing to bite on the mouthpiece. The guidewire (Jagwire, 0.035in; Boston Scientific, Natick, Massachusetts, USA) previously used for endoscopic retrog...
