Catheter induced cardiac arrhythmia is a well-known complication encountered during pulmonary artery or cardiac catheterization. Injury to the cardiac conducting system often involves the right bundle branch which in a patient with preexisting left bundle branch block can lead to fatal arrhythmia including asystole. Such a complication during central venous cannulation is rare as it usually doe...

OBJECTIVE To report one case of intrapyelic loop of a guide wire during double J catheter insertion. METHODS We report the case of a 24 year-old female, with the diagnosis obstructive uropathy secondary to pelvic tumor who required double J catheter insertion for urinary diversion. A loop of the guide wire was formed during the procedure which was finally solved without aggressive measures. ...

OBJECTIVES This study sought to prospectively evaluate the performance of a laser guide wire in crossing chronic total coronary occlusions in patients with a failed previous mechanical guide wire attempt. BACKGROUND Despite continued refinement of mechanical hardware available for coronary angioplasty, restoration and maintenance of blood flow through a chronically occluded coronary artery re...

Automatic lumen segmentation from intravascular optical coherence tomography (IVOCT) images is an important and fundamental work for diagnosis and treatment of coronary artery disease. However, it is a very challenging task due to irregular lumen caused by unstable plaque and bifurcation vessel, guide wire shadow, and blood artifacts. To address these problems, this paper presents a novel autom...

We appreciate the interest and comments of Vavuranakis et al regarding our article on the usefulness of placing a guide wire from the contralateral femoral artery in the management of vascular complications associated with transcatheter aortic valve implan-tation (TAVI). 1 Peripheral vascular disease following TAVI procedures has been identified as a predictor of mortality in a number of studie...

INTRODUCTION A simple technique to dilate urethral stricture using guide wire and sheath dilator has been described in pediatric urology. The aim of this study was to report the long-term outcome of the children who underwent dilation of the urethral stricture using guide wire and sheath dilator. MATERIALS AND METHODS From 1999 to 2004, a total of 52 children with documented urethral strictur...

BACKGROUND Guide wire-based simultaneous measurement of fractional flow reserve (FFR) and coronary flow reserve (CFR) is important to understand microvascular disease of the heart. The aim of this study was to investigate the feasibility of simultaneous measurement of FFR and CFR by one pressure-temperature sensor-tipped guide wire with the use of coronary thermodilution and to compare CFR by t...

When endovascular treatment is performed, angulation of the access route for a device can make the operative procedure difficult. We encountered a case in which we successfully completed thoracic endovascular aortic repair (TEVAR) in a patient with severely angulated aorta by applying 'double-wire technique'. The patient was an 80-year-old woman. An aneurysm with a 71-mm diameter was observed i...

for the endoscopist performing endo− scopic retrograde cholangiopancreato− graphy (ERCP). The papilla appears in a reversed position in the endoscopic view, making cannulation more difficult (l" Fig. 1, 2). The initial problem usually encountered is that of finding the afferent loop and advancement of the duodeno− scope to the papillary area. Negotiating the stoma and the afferent limb is a re−...

Purpose: to study in cadaver knees the position of the tibial tunnel in anterior cruciate ligament (ACL) reconstruction using the 65° Howell guide. Type of study: controlled laboratory study in vitro Methods: 21 fresh-frozen cadaver knees were employed. The ACL was resected and its tibial attachment was demarcated. To drill the guide wire we employed the Howell 65 degrees tibial guide which ref...
