BACKGROUND The purpose of this retrospective and prospective study is to evaluate the efficiency of ultrasound (US) guidance as a method of decreasing the malposition rate of central venous catheterization (CVC) in the emergency department (ED). METHODS We retrospectively enrolled 379 patients who underwent landmark-guided CVC (Group A) and prospectively enrolled 411 patients who underwent US-guided CVC (Group B) in the ED of a tertiary hospital. Malposition of the CVC tip is identified when the tip is not located in the superior vena cava (SVC). In Group B, we performed US-guided intravascular guide-wire repositioning and then confirmed the location of the CVC tip with chest radiography when the guide-wire was visible in any three other vessels rather than in the approached vessel. In the case of a guide-wire inserted into the right subclavian vein (SCV), the left SCV and both internal jugular veins (IJV) were referred to as the three other vessels. The two subject groups were compared in terms of the malposition rate using Fisher's exact test (significance = p < 0.05). RESULTS There were 38 malposition cases out of a total of 790 CVCs. The malposition rates of Groups A and B were 5.5% (21) and 4.1% (17), respectively, and no statistically significant difference in malposition rate between the two groups was found. In Group B, the malposition rate was decreased from 4.1% (17) to 1.2% (5) after the guide-wire was repositioned with US guidance, which led to a statistically significant difference in malposition rate (p < 0.01). CONCLUSIONS The authors concluded that repositioning the guide-wire with US guidance increased correct placement of central venous catheters toward the SVC.

We experienced an extremely unusual case of a 37-year-old woman who suffered from hemothorax soon after subclavian vein catheterization. Many case reports of a hemothorax or hematoma after central vein catheterization through the great vessels, such as the subclavian vein and internal jugular vein, have been published. However, this rare case showed a pinpoint-sized active bleeding site from a pulmonary arteriole rupture. During an emergency operation using thoracoscopy-assisted minithoracotomy, this bleeding site was successfully managed by primary repair.
Central venous catheterization is often necessary to manage critically ill patients in the intensive care unit and some surgical patients in the operating room. However, this procedure can lead to various complications. We experienced a case of subclavian venous catheterization that was complicated by looping, kinking, knotting, and entrapment of the guidewire. We were able to identify the extravascular looping and knotting of the guidewire under fluoroscopy and consequently removed it successfully. We suggest that a guidewire should be confirmed by fluoroscopic imaging if it has become entrapped.
Central venous catheterization is commonly used for supplying large amounts of fluids, total parenteral nutrition and for monitoring central venous pressure.
Numerous complications exist with the technique, including pneumothorax, arterial puncture with vessel injury, catheter embolus, mediastinal hematoma, hydrothorax, and the thrombus of the vein. We reported an uncommon case of pleural effusion, due to catheter tip migration and penetration, which occurred 4 days after central venous catheterization.
Central venous catheters provide an important means of vascular access and are increasingly used. Catheter occlusion refers to the inability to infuse or withdraw fluids from a catheter and could be caused by either thrombotic or nonthrombotic origin. We report an unusual malfunction of double lumen central venous catheter due to kinking and bending of the catheter at the opening site of proximal lumen.
BACKGROUND We describe the characteristics of malpractice claims related to central venous catheterization and identify causes and potential preventability of such claims.
METHODS: A retrospective study was performed by reviewing records at Lawnb and Lx CD-rom. The records on closed malpractice claim related to central venous catheterization were abstracted from the files available for analysis. The records were reviewed and were analysed to determine the factors associated with a successful defense. RESULTS Twelve closed claim cases, related to central venous cathetertization were reviewed in the data for malpractice. Catheter-related complications were pneumothorax, hemothorax, cardiac tamponade, pyothorax, hematoma due to arterial puncture, pseudoaneurysm. Almost cases resulted in indemnity payment and verdict for patient.
CONCLUSIONS: Although malpractice claims related to central venous catheterization were uncommon, they resulted in high rate and amount of indemnity payments. In pediatric patient, catheterization should be performed with attention.
Clinicians should consider the underlying disease of patients and do any pretreatment if needed. Post-procedural radiologic confirmation can improve patient outcome and is also associated with decreased indemnity risk. Informed consent is also important.
BACKGROUND The aim of this study was to determine whether the carina can be used as a landmark for evaluation of adequate central catheter tip position, and to examine the relationship between easily measurable body size and variable anatomical parameter. METHODS The SVC dimensions and relationship to radiographic landmarks were retrospectively determined from computerized tomography (CT) scans of 200 patients. The CT findings were assessed in terms of SVC length (SVCL), the distance between the carina and the right atrium inlet (CAL), and the sternal length (STL). Pearson's correlation and a regression test for height versus SVCL, STL versus SVCL and CAL were performed. RESULTS The median length of the SVC was 4.2 cm (range; 1.6 to 7.2 cm) and the distance between the carina and the right atrium inlet was 2.4 cm (range; 0.8 to 5.6 cm). With the regression test, height was correlated with SVCL (r(2)=0.09), and STL was correlated with both SVCL (r(2)=0.12) and STL (r(2)=0.04). CONCLUSIONS The carina was located always above the right atrium inlet. The carina was a reliable, simple anatomical landmark for the determination of correct placement with computerized tomography.
Central venous catheterization is one of the common procedures in the care of critically ill patients but numerous major complications have been reported. This report is about a case of sequential complications that were developed after two attempts of subclavian venous catheterization via supraclavicular approach for a critically ill 1.5 kg premature infant in intensive care unit. In the first attempt, the guidewire was cut and remained in the right atrium but fortunately removed without surgery. In the second attempt for the same patient, the catheter positioned out of the vessel. It was in right pleural cavity and caused hydrothorax. After third attempt, successful left subclavian vein catheterization was done.
