a new, over-the-wire technique for SLG tube placement during a single, same-day endoscopic procedure. First, we identify the existing fistula between the skin and the gastric body. We gently probe the gastrostomy tract and establish it with a guidewire under direct endoscopic vision. We grasp the guidewire with an endoscopic snare and withdraw it through the mouth in a standard manner. Second, ...

OBJECTIVE To the best of our knowledge there are only 3 reports of fractured guidewires inside the pelvicalyceal system, successfully removed with endourology techniques, and this is the first one presenting a tightly coiled intraparenchymal section. MATERIAL AND METHODS A 59-year-old woman was hospitalized for surgical treatment of a right kidney of reduced size. Past history revealed pyelol...

This study gains insight on the nature of flow blockage effects of small guidewire catheter sensors in measuring mean trans-stenotic pressure gradients Deltap across significant coronary artery stenoses. Detailed pulsatile hemodynamic computations were made in conjunction with previously reported clinical data in a group of patients with clinically significant coronary lesions before angioplast...

Central venous catheterization is an imperative tool in the critically ill patient to administer fluids, medications and for monitoring the central venous pressure. This procedure is associated with a variety of complications, some of which can be life threatening. In this brief report, we are addressing one of the rare complications of central venous catheterization which is missing the guidew...

Seldinger's technique is widely used to place central venous and arterial catheters and is generally considered safe. The technique does have multiple potential risks. Guidewire-related complications are rare but potentially serious. We describe a case of a lost guidewire during central venous catheter insertion followed by a review of the literature of this topic. Measures which can be taken t...

Background MRI-guidance for cardiovascular catheterization is appealing to reduce ionizing radiation exposure and to enable novel procedures. “Active” guidewire-antennas for MRI-guided procedures are often designed such that the tip and shaft have distinct signals [1] to improve navigation and to make it obvious when the tip moves out of plane. Here we present a method to isolate the signal fro...

The retained guidewire technique has been proposed as an alternative method for stabilizing the left ventricular lead in patients who experience repetitive intraoperative dislocation. This article concerns three patients, out of a total of 185 (1.6%) undergoing cardiac resynchronization therapy, who had to be treated using the retained guidewire technique because of demonstrable recurrent lead ...

Chronic total occlusion (CTO), a fascinating and dynamic niche in the realm of coronary artery disease, represents a major technical challenge for interventional cardiologists despite evolution of better guidewires, devices, experience and techniques. Effective wiring technique is the corner stone to success of percutaneous coronary intervention (PCI) in CTO. As a guide for guidewire crossing i...

For over 20 years, interventional methods have improved the outcomes of patients with cardiovascular disease or stroke. However, these procedures require an intricate combination of visual and tactile feedback and extensive training periods. An essential part of this training relates to catheter or guidewire manipulation. In this paper, we propose a composite model to realistically simulate a c...

Ultrasound-guided cannulation of a central venous catheter into the internal jugular vein (IJV) was performed in the intensive care unit for a critically ill patient. The catheter was inserted into the subclavian artery distally, despite prior ultrasound confirmation of the guidewire position using both the in-plane and out-of-plane views. The catheter was removed successfully by the interventi...
