Endoscopic biliary drainage (EBD) for hepatic hilar obstruction is sometimes challenging. Moreover, when unilateral biliary drainage has already been performed, if another intrahepatic bile duct also needs to be drained, EBDmay be mademore difficult because of tumor ingrowth and the narrowed angle from which the bile duct must be accessed. In this case, percutaneous biliary drainage (PTBD) or e...

We present the case of an unusual complication of insertion of a naso-jejunal feeding tube (NJT) using a guidewire, where the guidewire formed an alpha-loop in the naso-pharynx, becoming entrapped after cutting into the soft palate. This required ENT input and a general anaesthetic to rectify the situation.

We describe a case of chronic total occlusion of the right coronary artery ostium 5 months after a repeated Bentall procedure in a patient with Behçet's disease. In this patient, an antegrade approach to delivering the guidewire during percutaneous coronary intervention was not successful. Coronary angiography revealed the existence of collateral blood supply from the left coronary artery. Usin...

A fractured central venous catheter (CVC) with embolization of the distal fragment may lead to life-threatening complications. We had inserted a right subclavian CVC in a 68-year-old female which upon a follow-up chest X-ray appeared to have been sheared. A guidewire was inserted through the CVC until the J-tip was just beyond the tip of the CVC which were then withdrawn as a single assembly. W...

Therapeutic embolizations (surgical neuroangiographic procedures) in the head, neck, meninges, spine, and spinal cord are now accepted modes of treating vascular tumors and vascular malformations [1-4). We report our experience over the past 18 months with an open-ended guidewire through which we injected embolic agents. The purpose of the openended guidewire is to reach a more selective positi...

Guidewire recrossing into the abruptly occluded side branch (SB) after main vessel (MV) stenting in the coronary bifurcation is difficult, particularly if the SB has a dissection because the true lumen of SB is collapsed by a hematoma and the second guidewire easily goes into the false lumen. This paper reports a bailout technique to rescue the occluded SB that was complicated by a hematoma bec...

The zebra guidewire is widely used in endoscopic surgery. Because of its central mental core, it is not easy to break or shear off within the urinary tract. We report a case about the breakage of zebra guidewire in ureteroscopy (URS) with Holmium: YAG laser lithotripsy. It is easily to be managed by percutaneous access or open surgery. For the purpose of minimal invasiveness and risk, we perfor...

UNLABELLED In this case we herein report a dangerous complication from primary percutaneous coronary intervention, where an unnoticed loop of the guidewire was inadvertently made around the stent during provisional stenting. Since the guidewire and the stent were entangled, efforts to retrieve the guidewire only exacerbated the problem by compressing the stent like an accordion. We review those...

BACKGROUND CMR-guidance has the potential to improve tissue visualization during cardiovascular catheterization procedures and to reduce ionizing radiation exposure, but a lack of commercially available CMR guidewires limits widespread adoption. Standard metallic guidewires are considered to be unsafe in CMR due to risks of RF-induced heating. Here, we propose the use of RF-efficient gradient e...
