Abdominal visceral perforation by buried peritoneal dialysis catheters: Cause or coincidence?

Delayed visceral organ perforations after PD catheter insertions are extremely rare. We report two patients who presented with asymptomatic visceral perforation from their buried PD catheters. Five months after a laparoscopic buried PD catheter insertion in a 92-year-old man PD was initiated; bile and bowel contents were noted in the PD effluent. He subsequently expired (from pneumonia) to autopsy revealed the PD catheter within the small bowel. Despite this perforation, there was no evidence of peritonitis...

Study protocol for a multicentre, randomised, controlled trial to assess the effectiveness of antimicrobial central venous catheters versus ordinary central venous catheters at reducing catheter related infections in critically ill Chinese patients.

Catheter use is associated with many complications and is an iatrogenic source of morbidity and mortality in intensive care units (ICU). The catheter being studied (Certofix Protect) was developed to reduce the risk of catheter related infections. This clinical trial will compare the safety and efficiency of Certofix Protect with that of an ordinary Certofix catheter.

A longitudinal study of 321 patients with urinary catheter was conducted. Demographic factors, present health factors, urinary catheter factors, and indications of catheter use were collected. A total of 53.7% of urinary catheter-days were inappropriate. For both men and women, there was no significant difference in the incidence and common rationales o...

Reduction of catheter kinks and knots via radial approach.

Coronary angiography and percutaneous coronary intervention using the radial approach are becoming more frequent. Pronounced guide catheter manipulation in cases with tortuous access routes may lead to severe catheter kinking or knotting. The purpose of this review article is to present several techniques to resolve radial access catheter knots and kinks. First, simple maneuvers such as gentle traction, rotation, and guidewire advancement can often resolve minor kinking; however, complex loops and kinks are...

Design and performance evaluation of collision protection-based safety operation for a haptic robot-assisted catheter operating system.

The robot-assisted catheter system can increase operating distance thus preventing the exposure radiation of the surgeon to X-ray for endovascular catheterization. However, few designs have considered the collision protection between the catheter tip and the vessel wall. This paper presents a novel catheter operating system based on tissue protection to prevent vessel puncture caused by collision. The integrated haptic interface not only allows the operator to feel the real force feedback, but also combines...

The aim of this study was to investigate the influence of the electrode spacing of the mapping catheter on the voltage of the substrate map.

Factors Contributing to Phlebitis Among Adult Patients Admitted in the Medical-Surgical Units of a Central Hospital in Harare, Zimbabwe.

This descriptive survey identified factors contributing to phlebitis among 46 adult inpatients using a systematic random sample. The visual infusion phlebitis score was used for assessment. All participants had phlebitis, with stage 4 being most frequent. Factors identified were gender (males-91.7%); immunosuppression (human immunodeficiency virus-63.0%; diabetes-100%; immunosuppressive drugs-100%; absolute leucocyte count 1-90.9%); site of catheterization (dorsum of wrist-100%); catheter dwell time (2-4 da...

Haemodialysis catheter related central venous thrombosis; Clinical approach to evaluation and management.

Central venous catheter use is common among patients undergoing haemodialysis. Catheter related vascular thrombosis is a frequent complication, which results in catheter dysfunction. This may eliminate the affected vein as a potential route of vascular access and leads to significant morbidity of the limbs involved. Despite increasing prevalence, there is a dearth of evidence-based guidelines for managing such catheter related thrombi, often leading to treatment dilemmas in clinical practice. Minimizing the...

Left atrial shape predicts recurrence after atrial fibrillation catheter ablation.

Multiple markers LA remodeling, including LA shape, correlate with outcomes in AF. Catheter ablation is an important treatment of AF, but better tools are needed to determine which patients will benefit. In this study we use particle based modeling to quantitatively assess LA shape, and determine to what degree it predicts AF recurrence after catheter ablation.

Sonographic features of umbilical catheter-related complications.

Umbilical catheters are commonly used in the neonatal period for blood sampling or for administering medication or parenteral nutrition. The position of the catheter is usually confirmed with radiography. However, many complications associated with the use of umbilical catheters, such as liver collections from extravasation or vascular thrombosis, are not apparent on radiographs but can be easily diagnosed with ultrasound. This pictorial review illustrates the sonographic findings of complications that shou...

The Extended Dwell Peripheral Intravenous Catheter Is an Alternative Method of NICU Intravenous Access.

Establishing vascular access is a common neonatal intensive care unit procedure. The extended dwell peripheral intravenous (EPIV) catheter is a 6-cm and 8-cm silicone catheter for peripheral vein insertion, which is a newer vascular access device than peripherally inserted central catheters (PICCs) and peripheral intravenous (PIV) catheter. Extended dwell peripheral intravenous catheters have been widely used in adults but evidence in neonates is lacking.

Randomized controlled trial of Amigo® robotically controlled versus manually controlled ablation of the cavo-tricuspid isthmus using a contact force ablation catheter.

Radiofrequency catheter ablation (RFCA) of the cavo-tricuspid isthmus (CTI) is a common treatment for atrial flutter (AFL). However, achieving bi-directional CTI conduction block may be difficult, partly due to catheter instability.

First clinical use of novel ablation catheter incorporating local impedance data.

Successful catheter ablation is limited by both poor spatial resolution of abnormal local signals and inability to deliver an effective lesion due to poor tissue contact. We report first worldwide use of the Intellanav MiFi OI catheter (Boston Scientific), providing ultra-high density mapping and incorporating a 'DirectSense' algorithm to measure local tissue impedance (LI).

Mechanisms And Management Of Refractory Ventricular Arrhythmias In The Age Of Autonomic Modulation.

Ventricular arrhythmias are responsible for hundreds of thousands of deaths every year. Catheter ablation of ventricular tachycardia (VT) is an essential component of the management of these life-threatening arrhythmias. However, in many patients, despite medical and interventional therapy, VT recurs. Further, some VT substrates (mid-myocardial, left ventricular summit, intra-septal) are not easily targeted, due to limitations of currently available technology. In certain clinical settings, ventricular fibr...

A novel catheter with retractable stent that can prevent aortic insufficiency during left ventricular assist.

Left ventricle (LV) assist, which refers to the use of a mini-pump or catheter implanted across the aortic valve connected to the pump, can promote myocardial recovery after left ventricle failure. However, conventional LV assist catheters compress the aortic valve, which can induce aortic insufficiency. Here we describe a novel LV assist catheter containing a retractable stent at its distal end that may prevent such insufficiency. The device was tested in six goats in which the coronary artery was ligated ...

Catheter-Related Candida Endocarditis on the Right Atrial Septum - A Case Report.

The use of subcutaneous catheter devices has increased over the past two decades along with its associated infections. One of the complications is infective endocarditis (IE), which usually occurs on the valves of the heart. However, IE can rarely occur on the atrial septal wall. The most common pathogens associated with catheter-related IE are staphylococcus bacteria, and it is rarely caused by fungi. We present a case of a 75-year-old Caucasian female with infective endocarditis located on the right side...

Removal of Intrathecal Catheters Used in Drug Delivery Systems.

Implanted intrathecal drug delivery systems (IDDS) are increasingly used in the treatment of spasticity and in patients with refractory pain. Literature discussing complications associated with intrathecal pump placement is widely available. However, reports of complications following the removal of chronically placed catheters are scarce. We reviewed our series of patients who had surgery to remove the intrathecal catheter.

Wang's Forceps-Assisted Percutaneous Insertion and Fixation of Peritoneal Dialysis Catheter.

Percutaneous insertion of peritoneal dialysis catheters is theoretically most preferred by nephrologists because of the advantages of bedside performing, surgery independence, and minimal injury over other procedures of catheter placement such as open surgical dissection or laparoscopic operation. However, blindly placing catheters in the percutaneous procedure brings the risk of catheter malposition or bowel perforation; this largely retarded it's implementation. We had previously developed a novel techniq...
