PURPOSE To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. MATERIAL AND METHODS The study was performed prospectively in a randomized manner. The success and immediate ...

BACKGROUND The complication rate of central venous catheterization ranges from 4% to 35%. Brachial plexus injury can occur, mostly on the same side as the catheterization, without affecting the contralateral brachial plexus. CASE REPORT A 71-year-old woman received placement of a vein hemodialysis catheter via right internal jugular vein. Five days after the cannulation, she complained of contr...

Today, an increasing number of subcutaneous central venous access devices are implanted on a ambulatory basis either by percutaneous vein puncture or venous cut down. The aim of the present study was to prospectively evaluate which is the most suitable implant technique for ambulatory surgery by comparing subclavian vein puncture using a Seldinger technique with cephalic vein cut-down in terms ...

conclusions the us-guided method for cvc placement was superior to the traditional landmark method in terms of access time, number of attempts, success rate, and fewer complications. objectives this study aimed to compare the traditional landmark method vs. us-guided method of cvc placement in terms of complications and success rate. patients and methods in this randomized controlled trial, pat...

Vascular catheters are associated with complications such as infection, thrombosis and stenosis. The embolization of a venous catheter fragment is a rare complication. A 39-year-old woman underwent placement of a totally implantable venous access device for chemotherapy to treat a recurrent liposarcoma of the left thigh. The "pinch-off sign" was noted on a routine chest X-ray but that was ignor...

purpose: to determine the frequency of risk factors for retinal vein occlusion (rvo) in patients referred to a private clinic in rasht during 1995-2001. methods: this cross-sectional study was conducted on all patients with rvo who were referred to the clinic. sex, age, hypertension (htn), cardiovascular diseases (cvd), diabetes mellitus (dm), hypercoagulable states, glaucoma, smoking, hyperlip...

Central venous catheterization is of common practice in intensive care units; despite representing an essential device in various clinical circumstances, it represents a source of complications, sometimes even fatal, related to its management. We report the removal of a central venous catheter (CVC) that had been wrongly positioned through left internal jugular vein. The vein presented complete...

We determine if use of 16-cm central venous catheters (CVC) minimizes dangerous intracardiac catheter placements. We conducted a prospective study in a large community teaching hospital. Consecutive patients (n = 127) who required a CVC via either the internal jugular (IJV) or the subclavian vein (SCV) were assessed using 16 (n = 102) or 20-cm (n = 25) catheters. The main outcome measurements w...

When used in veterinary medicine, central venous catheters are typically inserted through the external jugular vein, with their caudal extension within the cranial vena cava. Radiographic or fluoroscopic guidance is recommended to assist in correctly placing these catheters. This article provides radiologic examples of common central venous catheter malpositions and complications.
