UNLABELLED BACKGROUND Various techniques for laparoscopic insertion of a peritoneal dialysis catheter have been described. Usually 2 - 3 ports are required, and complications related to the port sites (such as abdominal wall hernia, leakage, and hemorrhage) cannot be avoided. To minimize the potential complications, we designed a simplified 1-port laparoscopic technique for peritoneal dialys...

A 75-year-old woman was admitted due to pyometra. A central venous catheter was inserted from the left internal jugular vein under ultrasound guidance to create a parenteral nutrition route (1). A post-procedural X-ray film led us to suspect that inadvertent intra-aortic catheterization had occurred (Picture a). Although a blood gas analysis obtained via the catheter indicated intravenous cathe...

BACKGROUND Chronic venous access devices (CVADs), placed for phlebotomy and the administration of medications and nutrition, require fluoroscopy to confirm correct catheter position. Long-term central venous catheters placed using an electromagnetic catheter locating system (EMCLS) could result in decreased radiation exposure and decreased cost without compromising accuracy of position. METHO...

BACKGROUND Pressure and waveform at the catheter tip are continuously monitored during catheterization of pulmonary artery to ensure accurate catheter placement. We present a case in which pulmonary venous blood was unexpectedly collected from the pulmonary artery catheter despite pulmonary artery pressure and waveform detection at the catheter tip, and describe the measures taken to correct th...

A 68 year old woman was admitted for discitis and required subsequent antimicrobial therapy, necessitating placement of a 35 cm right-sided peripherally-inserted central catheter into the superior vena cava under ultrasound and fluoroscopic guidance. Eleven months after intial placement of the catheter, the patient was admitted for pneumonia. At that time, a posteroanterior dual energy chest ra...

BACKGROUND Based on the necessity to confirm the epiradicular catheter misplacement, epiradicular threshold current for the confirmation of catheter tip localization is required. METHODS Thirty-four adult patients with low extremity radiating pain were to receive epiradicular catheterization at the lumbosacral level. The epidural space was accessed percutaneously in cranial to caudal directio...

PURPOSE The challenge of catheter-tip visualization for interstitial needle placement in gynecologic brachytherapy remains unmet. We evaluate an approach to actively track tip locations and visualize catheter trajectories and surrounding soft-tissue in real-time during an intervention. The methods include development of clinical needles with magnetic resonance (MR) tracked microcoils, an MR tra...

Chronic peritoneal dialysis is an option for many patients with end stage renal disease. Laparoscopy offers an alternative approach in the management of dialysis patients. Over an 18-month period, laparoscopy was used for placement or revision of seven peritoneal dialysis catheters. All were placed in patients with end stage renal disease for chronic dialysis. Two catheters were initially place...
