Ultrasound guided catheter

Background : Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an alternative for failed endoscopic retrograde cholangiopancreatography (ERCP), with current success rates of 65-84% considered suboptimal. A novel ERCP catheter (SHOREN, Kaneka Corporation, Osaka, Japan) with a tapered 3.3-French tip may facilitate smoother insertion, potentially improving outcomes. Methods : This retrospective analysis encompassed EUS-HGS procedures conducted from January 2021 to August 2023 at four institutions. The aim of this study was to compare the performance of conventional and novel ERCP contrast catheters regarding the success rate of single-attempt catheter insertion, failure rates, technical success rates, and incidence of adverse events...

BACKGROUND: Catheterization of central vessels can be associated with early and late, potentially fatal complications. A proactive approach is imperative to reduce the frequency and magnitude of adverse events. Recently, the GAVeCeLT has proposed a protocol called SICA-PED (i.e. Safe Insertion of Central Access in Pediatric patients) and includes seven evidence-based strategies. METHODS: Through a single-center prospective observational study, the authors wanted to consolidate the efficacy and safety of these protocol in newborns...

MATERIALS AND METHODS: This prospective study was approved by the institutional review board with written informed consent obtained from all participants and was registered on clinicaltrial.gov. Consecutive patients with ovarian endometrioma between June 2020 and March 2023 were prospectively evaluated for two sessions of CDS...

The internal jugular vein (IJV) is occasionally used for blood access during catheter ablation. Additionally, accidental injury of the vertebral artery during an IJV puncture is a rare complication that can result in catastrophic events, such as death. However, vascular access complications cannot be completely prevented despite the introduction of ultrasound-guided punctures. Here, we present a case of a patient with symptomatic paroxysmal atrial fibrillation that required catheter ablation.

Securing reliable and high-quality peripheral intravenous catheter (PIVC) access is vital for patient-centered care. Factors such as patient condition, catheter type, and insertion method can influence PIVC dwell times. This review examines the differences in dwell times between traditional PIVCs and ultrasound-guided PIVCs (USGPIVCs) and their implications for patient care.

INTRODUCTION: Ultrasound-guided placement of Midlines catheters (MCs) is a standard procedure with many benefits for patients. Even if there are some guidelines worldwide, this invasive technique is still taught at the patient's bed and relies on mentoring in many care centers. The performance of this care by novice practitioners raises ethical and quality of care issues mainly because of its risk of complications. This study aimed to propose and assess a simulation-based learning method for the placement of MCs in novice practitioners...

OBJECTIVE: The objective of our study is to compare the success rate, duration, and incidence of complications of a right internal jugular vein (IJV) cannulation by using three different techniques. METHODOLOGY: A randomised controlled trial was conducted at a tertiary care teaching hospital. A total of 201 patients were randomly allocated to one of the following three groups (67 in each group). Techniques were categorised as anatomical landmark technique group (Group ALT), ultrasound guided pre-location group (Group USG-Pre), and real-time ultrasound-guided technique group (Group USG-RT)...

BACKGROUND: Peritoneal dialysis (PD) catheter related infections continue to be a major cause of morbidity and transfer to hemodialysis (HD) in PD patients. The treatment of tunnel infection (TI) could be challenging, especially when the infection involves the superficial cuff requiring the removal of the catheter. To spare the patient the loss of the catheter and the transfer to HD, several mini-invasive surgical techniques have been proposed as rescue therapy. Furthermore, nowadays, the rapid growth of digital technology has enormously increased the diagnostic sensibility of the echo signal allowing to accurately defines the extent of the infectious process along the PD catheter tunnel...

BACKGROUND: The aim of this study was to present demographic information of patients undergoing totally implantable venous access port (TIVAP) implantation and to investigate the rates of early and late complications, assessing the benefits of performing the procedure underUS guidance. METHODS: From May 2018 to December 2023, the outcomes of a total of 537 TIVAP implantation procedures were analyzed retrospectively. Data of the surgeons' experiences for both puncture methods (anatomical landmarks and ultrasound guidance) are presented in the study...

Scapulothoracic arthrodesis (STA) surgery is performed to stabilize the scapula in patients with facioscapulohumeral dystrophy (FSHD). Postoperative pain could be a major problem even while using erector spinae plane block (ESPB). We performed a preoperative ESPB with an intraoperative ESPB catheter, but rescue analgesia was needed for pain in the periscapular area in the postoperative period. The patient's pain score was reduced by applying an ultrasound-guided dorsal scapular nerve (DSN) and long thoracic nerve (LTN) block...

BACKGROUND: The use of percutaneous stellate ganglion block (SGB) in the management of drug-refractory electrical storm (ES) has been increasingly reported in the last years. Few data are available on the safety, duration, and dosage of local anaesthetic used. CASE SUMMARY: A 66-year-old male patient with a history of ischaemic cardiomyopathy and an implantable cardioverter-defibrillator (ICD) presented to the emergency room complaining several ventricular arrhythmias and ICD shocks received in the last 24 h...

BACKGROUND: Brachial plexus catheter placement at the interscalene level is beneficial for shoulder analgesia but presents logistical challenges due to the superficial nature of the plexus at this level, increased patient movement in the neck, and therefore higher likelihood for catheter dislodgement. METHODS: Patients requiring shoulder arthroscopy and suprascapular nerve decompression were identified. Under arthroscopic guidance, a catheter was placed percutaneously into the scalene medius muscle next to the suprascapular nerve and the upper trunk of the brachial plexus...

BACKGROUND: Infected acute necrotic collection (ANC) is a fatal complication of acute pancreatitis with substantial morbidity and mortality. Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis; however, there is great controversy about the optimal drainage time, and better treatment should be explored. CASE SUMMARY: We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancreatitis; conservative treatment was ineffective, and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography (CT)...

Catheter-directed intervention for acute iliofemoral deep venous thrombosis (DVT) have been increasingly used over the past fifteen years to target severe symptomatology and prevention of post-thrombotic syndrome (PTS) incidence or reduce its severity if it were to develop. Aside from successful thrombus removal, adjunctive stents are frequently required to treat an uncovered lesion or significant residual thrombus to ensure quality of life improvement besides retarding DVT recurrence and PTS. As the evidence is mounting, the need and role for stenting as well as the principles of an optimal technique in the acute DVT setting are now better understood...

OBJECTIVES: Arterial catheters (ACs) are critical for haemodynamic monitoring and blood sampling but are prone to complications. We investigated the incidence and risk factors of AC failure. METHODS: Secondary analysis of a multi-centre randomised controlled trial (ACTRN 12610000505000). Analysis included a subset of adult intensive care unit patients with an AC. The primary outcome was all-cause device failure. Secondary outcomes were catheter associated bloodstream infection (CABSI), suspected CABSI, occlusion, thrombosis, accidental removal, pain, and line fracture...

Optimal pain management after open abdominal surgery is essential but can be difficult to achieve. The effects of inadequate analgesia go beyond the first few postoperative days; severe acute postoperative pain may contribute to the development of chronic postsurgical pain. Thoracic epidural analgesia is a traditional approach to the management of acute pain after open abdominal surgery but has multiple possible contraindications and can be technically challenging. In our hospital, we typically offer ultrasound-guided rectus sheath blocks with catheters when epidural analgesia is not feasible...

OBJECTIVE: Explore the efficacy of contrast-enhanced ultrasound (CEUS) via vessels and surgical drain guidance percutaneous catheter drainage (PCD) in the treatment of pyogenic liver abscesses (PLA). MATERIALS AND METHODS: A total of 86 PLA patients who underwent PCD treatment in our hospital from May 2018 to February 2023 were retrospectively selected...

BACKGROUND: Transvenous pacemaker placement is an integral component of therapy for severe dysrhythmias and a core skill in emergency medicine. OBJECTIVE: This narrative review provides a focused evaluation of transvenous pacemaker placement in the emergency department setting. DISCUSSION: Temporary cardiac pacing can be a life-saving procedure. Indications for pacemaker placement include hemodynamic instability with symptomatic bradycardia secondary to atrioventricular block and sinus node dysfunction; overdrive pacing in unstable tachydysrhythmias, such as torsades de pointes; and failure of transcutaneous pacing...

Coronary angiography has long been the standard for coronary imaging, but it has limitations in assessing vessel wall anatomy and guiding percutaneous coronary intervention (PCI). Intracoronary imaging techniques like intravascular ultrasound (IVUS) and optical coherence tomography (OCT) can overcome these limitations. IVUS uses ultrasound and OCT uses near-infrared light to visualize coronary pathology in unique ways due to differences in temporal and spatial resolution. These techniques have evolved to offer clinical utility in plaque characterization and vessel assessment during PCI...

OBJECTIVE: To test the Doppler guide wire (DGW) for navigation of the wire positioning by color Doppler ultrasound in the setting of percutaneous coronary intervention (PCI). METHODS: An acoustically active DGW was tested in a water tank before its in vivo use. A waveform generator was connected to the DGW, and a transducer scanned the DGW to visualize a Doppler shift signal between the vibrating piezoelectric crystal located at the DGW tip and Doppler signal from the transducer as a distinct, instantaneous color marker...
