Recent studies have revealed that deep pancreatic duct wire passage, even in the absence of contrast injection, is a major technique-related culprit in post-ERCP pancreatitis, unless followed by placement of a pancreatic stent. As guidewire cannulation becomes increasingly widespread, precise control of the guidewire is thus critical. The first randomized trial to compare endoscopist-controlled wire guided vs. assistant-controlled bile duct cannulation has shown a significant reduction in post ERCP pancreatitis when the physician manipulates the wire...

OBJECTIVE: To examine the presence and localization of lipid-core plaque (LCP) in coronary vessels with chronic total occlusions (CTOs) using near-infrared spectroscopy (NIRS). METHODS: NIRS imaging was performed after guidewire crossing of the occlusion in 15 patients with CTOs. LCP was defined as ≥2 adjacent 2 mm yellow blocks on the block chemogram. We also measured the maximum lipid-core burden index (LCBI) in a 4 mm length of artery (maxLCBI4mm). Large LCP was defined as maxLCBI4mm ≥500...

BACKGROUND Central venous catheterization is a common tool used in critically ill patients to monitor central venous pressure and administer fluids and medications such as vasopressors. Here we present a case of a missing guide wire after placement of peripherally inserted central catheter (PICC), which was incidentally picked up by bedside ultrasound in the intensive care unit.  CASE REPORT A 50-year-old Hispanic male was admitted to the intensive care unit for alcohol intoxication. He was managed for septic shock and required placement of a peripherally inserted central line in his left upper extremity for antibiotics and vasopressor administration...

BACKGROUND: Our initial experience using the two-stage aspiration technique (TSAT) with proximal flow arrest by a balloon guiding catheter is presented. In TSAT, aspiration is applied with the 5MAX ACE and also with the 3MAX catheter with a Penumbra aspiration pump, while arresting proximal flow by balloon inflation. METHODS: In patients treated with TSAT, clinical data including National Institutes of Health Stroke Scale (NIHSS) score at admission and the modified Rankin Scale (mRS) score at discharge, as well as procedural data including the Thrombolysis in Cerebral Infarction (TICI) score, procedural time, and complications were analyzed...

BACKGROUND: The Navvus pressure sensor-equipped microcatheter allows to measure functional stenosis severity over a work-horse guidewire and is used as a more feasible alternative to regular sensor-equipped wires. However, Navvus is larger in diameter than contemporary sensor-equipped guidewires and may, thereby, influence functional measurements. The present study evaluates the hemodynamic influence of the Navvus microcatheter. METHODS AND RESULTS: In patients with intermediate coronary stenosis, coronary pressure and flow velocity were measured using a dual sensor-equipped guidewire before and after introduction of Navvus...

BACKGROUND: As an alternative to open surgical repair, perventricular device closure provides minimally invasive treatment for doubly committed subarterial ventricular septal defects. However, unlike percutaneous transcatheter access, mini-thoracotomy is still needed. This report describes the percutaneous perventricular device closure technique and its short-term results for this type of heart defect. METHODS: Sixteen patients who had isolated doubly committed subarterial ventricular septal defects underwent percutaneous perventricular device closure...

BACKGROUND: Transcoronary pacing is used for treatment of unheralded bradycardias in the setting of percutaneous coronary interventions (PCI). OBJECTIVES: In the present study we introduced a new concept - the double guidewire approach - for transcoronary pacing in a porcine model. METHODS: Transcoronary pacing was applied in 16 adult pigs under general anaesthesia in an animal catheterization laboratory. A special guidewire with electrical insulation by PTFE coating except for the distal part of the guidewire was positioned in the periphery of a coronary artery serving as the cathode...

BACKGROUND: Inability to advance a balloon is a well-recognized cause leading to a failure in recanalization of chronic total occlusions (CTOs) despite successfully passing a guidewire. A few techniques and devices have been introduced to facilitate balloon passage, especially the use of Tornus catheter. However, complex manipulation, expensive cost, and availability limit the application of these methods. This study was to evaluate the efficiency and safety of "seesaw balloon-wire cutting" technique in comparison with Tornus catheter for balloon uncrossable CTOs...

The Crosser catheter is a unique device that facilitates antegrade intraluminal recanalization by high-frequency vibration energy and cavitation. We used this device not only as a chronic total occlusion (CTO) crossing device, but also as a flossing device in stenotic lesions and we also evaluated the efficacy of this device when used with both the "Crosser preceding" and the "Guidewire preceding" in CTOs. Complications related to this device were investigated, too. We retrospectively analyzed a total of 90 consecutive patients with peripheral artery disease in the femoropopliteal artery and below-the-knee artery (BTA)...

Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population is unclear. Several reports have indicated that hemodialysis patients have a higher risk of methicillin-resistant Staphylococcus aureus infection...

STUDY OBJECTIVE: Several authors have reported rare, but severe, complications associated with the length of the intravascular guidewire during central venous catheter placement, as the wire tip can cause cardiac arrhythmia or perforation or become trapped within the vessel. Although one report investigated the optimal guidewire length using fluoroscopy, few reports have precisely measured guidewire position using transesophageal echocardiography (TEE). Here, we investigated the appropriate intravascular length of a guidewire for right internal jugular vein approach using TEE during cardiac surgery...

After rescuing an airway with a supraglottic airway device, a method to convert it to a cuffed tracheal tube is often needed. The best method to do this has never been directly studied. We compared three techniques for conversion of a standard LMA(®) Unique airway to a cuffed endotracheal tube using a fibrescope. The primary endpoint was time to intubation, with secondary endpoints of success rate, perceived difficulty and preferred technique. We also investigated the relationship between level of training and prior training and experience with the techniques on the primary outcome...

OBJECTIVE: To present a unique case of guide wire breakage as a rare complication during posterolateral endoscopic lumbar discectomy. BACKGROUND: Posterolateral endoscopic lumbar discectomy (PELD) has become a routinely performed minimally invasive spinal procedure. However, several complications of PELD have attracted our concerns, including the intraoperative injury to neural and vascular structures and failure of the surgery. We have countered a rare intraoperative complication of guidewire breakage during a PELD procedure, as far as we know, this has not been reported previously, and we wish to draw attention to this hazard...

BACKGROUND: Although several new techniques have been introduced for CTO such as the retrograde approach, the fundamental question of what type of guidewire is the most appropriate as a primary guidewire in the antegrade approach has not been answered. METHODS: The G-FORCE study was designed as a prospective multicenter randomized controlled trial to determine the efficient primary guidewire in antegrade approach for chronic total occlusion (CTO). The first guidewire was randomly assigned to a regular size distal tip group (0...

Magnetic particle imaging (MPI) is able to provide high temporal and good spatial resolution, high signal to noise ratio and sensitivity. Furthermore, it is a truly quantitative method as its signal strength is proportional to the concentration of its tracer, superparamagnetic iron oxide nanoparticles (SPIOs), over a wide range practically relevant concentrations. Thus, MPI is proposed as a promising future method for guidance of vascular interventions. To implement this, devices such as guide wires and catheters have to be discernible in MPI, which can be achieved by coating already commercially available devices with SPIOs...
