Malposition of Central Venous Catheter: Presentation and Management

Imaging of the umbilicus

The umbilicus is a scar of the umbilical cord containing various embryonic remnants that can lead to postnatal diseases. It is the collection point for blood and lymphatic flow and other structures. Hence, various diseases and conditions can occur. In this review, we aimed to categorize umbilical diseases based on the embryonic remnants, including urachal remnants, omphalomesenteric duct anomalies, and complications of the umbilical arteries and veins. The urachus, formed from the allantois, can result in anomalies such as patent urachus and urachal cysts, with infections being the most common complication. Radiologists must note that urachal carcinoma is a rare complication presenting with characteristic imaging findings. The omphalomesenteric duct can lead to Meckel's diverticulum, the most prevalent gastrointestinal anomaly. In addition, obliterated umbilical arteries and veins can cause various conditions, including hernias and abscesses. This review also summarizes the umbilical ring lesions, such as gastroschisis and omphalocele, and iatrogenic lesions associated with laparoscopic procedures and catheter placement. Imaging techniques such as ultrasound, computed tomography, and magnetic resonance imaging are crucial for diagnosing and managing these conditions. Understanding the embryological basis and imaging features of umbilical diseases is vital for timely diagnosis and treatment.

Virtual Chest Radiographs Developed From Computed Tomography Images for Differentiating Central Venous Versus Misplaced Arterial Lines and for Training Radiologists

OBJECTIVE

Radiographic findings to identify central venous catheter misplacement in the arteries, which can cause lethal complications, have not been fully evaluated, and its training is difficult because it is rare. The purpose of this study is to clarify radiographic findings for differentiating central venous and misplaced arterial lines using virtual chest radiographs and elucidate their usefulness in training radiologists.

METHODS

This retrospective study included 150 patients (mean age, 67 [SD, ±12] years; 97 men) who underwent colon cancer surgery between January 2018 and December 2020. Virtual chest radiographs, including 6 oblique projections at 5° intervals, were developed from the computed tomography images using ray-sum reconstruction. Virtual venous and arterial lines were drawn from the right neck to the superior vena cava and aorta, respectively. Diagnostic abilities, including area under the curve (AUC) analysis of the 7 proposed radiographic findings for differentiating these lines in 100 patients, were evaluated. The diagnostic performance, including AUC analysis by 5 radiologists in the other 50 patients, was compared before and after disclosing these results to the radiologists.

RESULTS

The findings of crossing over the right paratracheal stripe and running along the paracaval line showed the highest AUC for indicating arterial and venous lines in the frontal, right anterior oblique 15°, and left anterior oblique 15° projections (AUC = 0.992, 0.991, and 0.979, and 1.000, 0.994, and 0.998, respectively). The diagnostic performance of the radiologists improved after informing them of these results (AUC, 0.982-0.999 to 0.993-1.000 [ P  = 0.145-1.000] for the frontal projections and 0.932-0.970 to 0.967-0.995 [ P  = 0.075-0.150] for the oblique projections).

CONCLUSIONS

Virtual chest radiographs created from computed tomography images were useful for clarifying radiographic findings for differentiating central venous and misplaced arterial lines and for training radiologists.

Tunneled Hemodialysis Catheter Making its Way into the Spinal Canal: An Unusual Complication

The procedure of tunnelled hemodialysis catheter insertion is generally considered safe. We report the case of a lady who had a malpositioned femoral tunneled hemodialysis catheter that entered into the spinal canal causing neurological weakness. The catheter was later safely removed leading to partial neurological recovery.

"It Looks Arterial": The Chest X-Ray of Nightmares

Central venous access is a common procedure for a variety of indications such as dialysis, plasmapheresis, or difficult venous access. Although a relatively safe procedure that can be done at the bedside, complications can still occur. Recognition and management of central line complications such as vascular injury and bleeding, infection, and misplacement are important when caring for patients with central vascular access and for the proceduralist who places the central line. Here we present an uncommon complication of internal jugular central access where a left internal jugular central line placement resulted in misplacement of the line in the hemiazygos vein.

Systematic review of ultrasound-guided central venous catheter placement-related complications in neonates and infants aged <12 months

OBJECTIVE

Although ultrasound can be considered an assistant method, successful placement of a central venous catheter (CVC) in infants is still challenging. The incidence of CVC placement-related complications is still high. Therefore, this systematic review aimed to synthesize evidence to assess the effects of ultrasound-guided CVC placement on adverse outcomes in infants and neonates aged <12 months.

METHODS

PubMed, Ovid, EMBASE, and the Cochrane Library were searched to identify potentially relevant studies. The main outcome was the incidence of adverse events, which included inadvertent arterial puncture, hematoma, pneumothorax and hemothorax, catheter kinking, threading, and malpositioning problems, venous thrombosis, catheter-related infection, phlebitis, and cardiac tamponade.

RESULTS

Eleven studies involving 2097 patients were included in the final analysis. The odds of inadvertent arterial puncture, and catheter kinking, threading, and malpositioning problems were lower in the ultrasound group than in the control group. No significant difference was detected in the incidence of hematoma or venous thrombosis between the control and ultrasound groups. Other complications, such as pneumothorax, hemothorax, phlebitis, and cardiac tamponade, rarely occurred.

CONCLUSION

Ultrasound-guided CVC placement can improve the safety of punctures in neonates and infants. CVC punctures should be guided in real-time by ultrasound.

Rare Central Venous Catheter Malpositions: A Case Series

Central venous catheters are a procedure that provides vascular access, allowing the application of various clinical treatments and the measurement of some hemodynamic values. It provides access to the internal jugular vein, subclavian vein, and, femoral vein with a large-bore catheter. There are mechanical, infectious, and thromboembolic complications resulting from central venous catheter placement and care. Central venous catheter malposition is a rare catheter complication that may be encountered. The location of the central venous catheter can be evaluated with imaging techniques such as posteroanterior chest radiograph, ultrasonography, central venous catheter waveform, and transesophageal echocardiography. Five malposition cases detected by imaging after the central venous catheter procedure in our clinic are presented.

Malposition of Central Venous Catheter into Coronary Sinus throughout the Persistent Left Superior Vena Cava and Other Complications Related to Catheterization

This case concentrates on the persistent left superior vena cava (PLSVC), a rare vascular anomaly which contributes to central venous catheter (CVC) misplacement. A 72-year-old woman with renal insufficiency presented to the hospital with recurrent bleeding from her permanent CVC device placed in the right common jugular vein. An initial attempt to replace the device was unsuccessful, necessitating the placement of a secondary catheter in the left jugular vein. Shortly after the procedure, the patient developed swelling of the face and neck. Further diagnostic imaging, including a chest radiograph and computed tomography (CT), revealed CVC misplacement in the PLSVC and coronary sinus, thrombosis of the common jugular vein, and a posterior mediastinal hematoma. Conservative therapy of the mediastinal hematoma was implemented and proved effective in this case. A temporary CVC was inserted into the left femoral vein. Two months later, the catheter underwent further dysfunction and a decision was made to place a long-term permanent CVC via the right femoral vein. The patient is currently awaiting an arteriovenous fistula for dialysis use. This case emphasizes the importance of radiological techniques for CVC procedural placement, as well as the detection of congenital abnormalities. Providers regularly placing CVCs should have an in-depth knowledge of the possible complications and potential anatomical variations, especially as seen in high-risk patients.

Two Cases of Malpositioning of Internal Jugular Central Venous Catheters: A Review of Literature and Current Treatment Recommendations

Percutaneous central venous catheterization, despite ultrasound guidance, is known to carry significant risks. While central venous catheters are widely used in clinical practice, they are also associated with various complications, including incorrect positioning during insertion. Arterial puncture is a well-recognized complication, and although unintended subclavian or carotid artery cannulation is rare, it can lead to serious consequences. We present two cases, in which a dual-lumen, non-tunneled temporary hemodialysis catheter was inadvertently inserted into the left common carotid artery and in the left innominate vein.

Angiographic evidence of an inadvertent cannulation of the marginal sinus following central line migration: illustrative case

BACKGROUND

Central venous catheters (CVCs) play an indispensable role in clinical practice. Catheter malposition and tip migration can lead to severe complications. The authors present a case illustrating the endovascular management of inadvertent marginal sinus cannulation after an internal jugular vein (IJV) catheter tip migration.

OBSERVATIONS

A triple-lumen CVC was inserted without complications into the right IJV of a patient undergoing a repeat sternotomy for aortic valve replacement. Two weeks postinsertion, it was discovered that the tip had migrated superiorly, terminating below the torcula in the posterior fossa. In the interventional suite, a three-dimensional venogram confirmed the inadvertent marginal sinus cannulation. The catheter was carefully retracted to the sigmoid sinus to preserve the option of catheter exchange if embolization became necessary. After a subsequent venogram, which displayed an absence of contrast extravasation, the entire catheter was safely removed. The patient tolerated the procedure well.

LESSONS

Clinicians must be vigilant of catheter tip migration and malposition risks. Relying solely on postinsertion radiographs is insufficient. Once identified, prompt management of the malpositioned catheter is paramount in reducing morbidity and mortality and improving patient outcomes. Removing a malpositioned catheter constitutes a critical step, best performed by a specialized team under angiographic visualization.

Accidental Diagnosis of Isolated Persistent Left Superior Vena Cava After an Elective Central Venous Access Procedure for Chronic Hemodialysis: Clinical Implications and Precautions From a Case Report

Persistent left superior vena cava (PLSVC) is the most frequent thoracic venous anatomical variant in the general population. Isolated PLSVC, without formation of the right superior vena cava, is described in 10% of cases of PLSVC only. While it can be associated with congenital heart disease, arrhythmias, and premature death, adult patients with PLSVC are mostly asymptomatic, and the diagnosis is usually accidental. We present the case of a 72-year-old male with end-stage renal disease who was started on urgent hemodialysis through a temporary non-tunneled femoral central venous catheter (CVC) in the SLED (slow low-efficiency dialysis) modality and later remained dependent on hemodialysis. At this stage, placement of a tunneled CVC in the right internal jugular vein was necessary and fluoroscopy guidance was not available. There were no complications during the procedure, but postoperative conventional chest radiography revealed an inadequate positioning of the CVC tip in the left hemithorax, crossing the midline. Subsequently, the diagnosis of PLSVC was obtained by performing a thoracic angio-CT scan, confirming CVC tip positioning inside the PLSVC, and also excluded the presence of cardiac defects or additional anatomical variations of the great vessels of the thorax. Early evaluation for the creation of autologous vascular access was started under our care, and there were no mechanical or other complications associated with hemodialysis sessions during early follow-up after discharge.

Potassium Chloride-Induced Phlebitis via a Malpositioned Central Venous Catheter

We present a case of potassium chloride-induced phlebitis with severe, burning, left-sided chest pain when infused via a malpositioned central venous catheter. Using a malpositioned central venous catheter requires careful consideration, but this novel case prompts the need for additional review before its use for the infusion of potentially irritating medications.

A reappraisal of pediatric thoracic surface anatomy

Accurate knowledge of surface anatomy is essential for physical examination, invasive procedures, and anatomy education. Individual factors such as age make surface landmarks variable so accurate descriptions are needed. The aim of this study is to describe age-related surface landmarks for intrathoracic structures in children. A total of 156 thoracic computed tomography scans of children aged 0-18 years were categorized into six groups, and the associations between major intrathoracic structures and surface landmarks were analyzed. Sternal angle is an accurate surface landmark for the azygos vein-superior vena cava junction in all age groups. However, the aortic arch (except in the 0-1 year group), the bifurcation of the pulmonary trunk and the tracheal bifurcation in those aged 15-18 years were not within this plane. The left brachiocephalic vein was located behind the ipsilateral sternoclavicular joint except in the 1-3 years group, and the right was behind it in children older than 6 years. The apex of heart was at the 5th intercostal space level in the 0-1 and 12-18 years groups; however, it was higher in the other groups. The lower borders of the lungs were at the sixth costal cartilage level in the midclavicular line, eighth intercostal space level in the midaxillary line, and T12 adjacent to the vertebral column in the 15-18 years group; the lower borders were at higher levels in younger children. Defining the variations in surface anatomy by in vivo studies will increase its clinical and pedagogical value.

Chest X-ray Interpretation: Detecting Devices and Device-Related Complications

This short review has the aim of helping the radiologist to identify medical devices when interpreting a chest X-ray, as well as looking for their most commonly detectable complications. Nowadays, many different medical devices are used, often together, especially in critical patients. It is important for the radiologist to know what to look for and to remember the technical factors that need to be considered when checking each device's positioning.

Supradiaphragmatic central venous catheter malposition detection using the parasternal long-axis echocardiographic view and dextrose 50% contrast solution: A pilot study

Background

Contrast-enhanced ultrasonography (CEUS) using saline was studied to detect supradiaphragmatic central venous catheter malposition. Commonly used echocardiographic views are apical 4-chamber (A4c) and subcostal views. However, this standard method is not feasible in certain situations. We explored the feasibility of the right ventricle inflow parasternal long axis (RVI-PLAX) echocardiographic view and dextrose 50% (D50%) contrast solution for detecting supradiaphragmatic central venous catheter malposition.

Method

This pilot study screened 60 patients who underwent ultrasound-guided supradiaphragmatic central venous catheter insertion. We compared the investigators' guidewire's J-tip detection, D50% rapid atrial swirl sign (RASS) findings on the RVI-PLAX view and the central venous catheter tip on chest radiograph. We also compared the mean capillary blood sugar level before and after the 5 ml D50% flush.

Results

No guidewire J-tips were detected from the RVI-PLAX view. The first and second investigators' diagnosis of central venous catheter malposition detected on RVI-PLAX CEUS achieved an almost perfect agreement (κ = 1.0 (95% confidence interval (CI): 0.90 to 1.0), p < .0001). The RVI-PLAX CEUS was not able to detect two central venous catheter malpositions (one atrial malposition and one left brachiocephalic vein venous catheter malposition). The capillary blood sugar was significantly elevated (8.96 mmol/L vs. 9.75 mmol/L) after D50% flush (p < 0.005) with no complications reported within 30 minutes after the D50% flush.

Conclusion

RVI-PLAX view should not be used for guidewire detection. CEUS using D50% and RVI-PLAX view are potentially useful tools in detecting central venous catheter malposition. Further studies comparing them with conventional methods are needed.

A Pictorial Review of Radiologic Findings of Foreign Bodies in the Thorax

Thoracic foreign bodies (FBs) are serious and relatively frequent in emergency departments. Thoracic FBs may occur in association with aspiration, ingestion, trauma, or iatrogenic causes. Imaging plays an important role in the identification of FBs and their dimensions, structures, and locations, before the initiation of interventional treatment. To guide proper clinical management, radiologists should be aware of the radiologic presentations and the consequences of thoracic FBs. In this pictorial essay, we reviewed the optimal imaging settings to identify FBs in the thorax, classified thoracic FBs into four types according to their etiology, and reviewed the characteristic imaging features and the possible complications.

Inadvertent Arterial Cannulation and Norepinephrine Infusion Due to a Misplaced Central Venous Catheter

Central venous catheter (CVC) insertion is one of the most common procedures done for critically ill patients. The subclavian vein is the particular preferred site. Misplacement of a CVC via the subclavian vein is frequent and can result in life-threatening complications. We aim to report a rare complication of misplaced CVC in the left subclavian vein and norepinephrine infusion that was associated with right upper limb ischemia. Immediate recognition and intervention are key to prevent further complications. The use of ultrasound has proven to reduce such complication, and the hospital implemented the use of ultrasound prior to any CVC placement.

Trimmed central venous catheters in pediatric cardiac surgery: Does height or weight correlate with the amount trimmed?

BACKGROUND

Due to excess catheter length, pediatric patients undergoing cardiac surgery frequently have the tip of the central venous catheter trimmed while on bypass to obtain optimal catheter positioning.

AIMS

We sought to determine if there is a correlation between the patient's height or weight and the length of catheter removed. Our secondary aim compared the instances of central line-associated bloodstream infections and venous thromboembolisms between the trimmed and untrimmed catheters.

METHODS

This retrospective study included patients having undergone cardiac surgery over a 3-year period who had an 8 cm central venous catheter placed in the right internal jugular vein. Hospital lists of central line-associated bloodstream infections and venous thromboembolisms that occurred were cross referenced with our study patients.

RESULTS

There were 147 cases where the 8 cm central venous catheter was trimmed, which represents 35% of the cases. Of the catheters that were cut, on average 2.17 cm was removed. There is negligible correlation between the length of catheter removed and patient height (r = -.19, p = .021). There is negligible correlation between the length of catheter removed and patient weight (r = -.17, p = .039). There were no instances of central line-associated bloodstream infections or venous thromboembolisms attributed to the trimmed catheters. Of the 273 untrimmed catheters, there were no instances of an infection and one instance of a venous thromboembolism.

CONCLUSION

Right internal jugular 8 cm central venous catheters are trimmed during pediatric cardiac surgery, and there is minimal correlation between the length removed and the patient height or weight. Due to the difficulty in estimating the proper length of a central venous catheter in smaller pediatric patients, placing an 8 cm long catheter in these patients and then trimming the distal tip while on bypass may be the most accurate way to properly position a catheter.

Case Report of a Left-sided Superior Vena Cava Causing Unique Positioning of Central Line

Introduction

Persistent left-sided superior vena cava is a rare congenital venous malformation. While often clinically asymptomatic, these variations in normal anatomy may give rise to complications with central venous catheter placement.

Case Report

We present a case of a 71-year-old male who presented to the emergency department with sepsis of unknown etiology. A right-sided central venous catheter was placed, and due to a persistent left-sided superior vena cava the post-procedure chest radiograph showed a uniquely positioned catheter tip within the left atrium.

Conclusion

A persistent left-sided superior vena cava may lead to uniquely positioned catheter tip placement on post-procedural imaging. This case demonstrates the need to consider variants in normal venous anatomy, such as persistent left-sided superior vena cava, to aid with correct interpretation of post-procedure imaging findings.

Partial Anomalous Pulmonary Venous Return Diagnosed by Central Catheter Misplacement

Anomalous venous connections of the left lung can either affect all of the veins or only the upper lobe. They mostly drain into the innominate vein. We present the case of a patient who underwent a coronary bypass operation and was prepared with insertion of central lines including Swan-Ganz catheter through both the internal jugular veins. Blood gas analysis obtained from these catheters suggested the presence of a left-to-right shunt. CT (computed tomography) imaging confirmed a pulmonary venous anomaly with misplacement of the left-sided catheter in an abnormal pulmonary vein. Such a rare condition can be suspected by obtaining arterialized blood samples and measuring the mean pressure through central catheters.

Accidental Central Venous Catheter Placement in the Internal Thoracic Vein: A Case Report

Central venous catheter (CVC) placement is an essential component of critical care medicine. CVC malposition is a known complication of internal jugular vein (IJV) cannulation. However, catheterization of the internal thoracic vein (ITV) is much rarer. Only a handful of case reports have been documented, and guidelines for management are therefore lacking. Our case study describes this rarely occurring ITV cannulation along with the discussion of risk factors, warning signs of malpositioning, and subsequent management plans to optimize patient safety. Previous studies have used fluoroscopy and agitated saline flush tests to confirm that agents administered through an ITV-located catheter would reach the right atrium. Considering this, it would follow that a catheter in this site could theoretically be used for medication administration, especially in emergency settings. This hypothesis remains the most novel part of our case study and might prompt further exploration of management strategies in this particular situation.

Overlooked guide wire: a multicomplicated Swiss Cheese Model example. Analysis of a case and review of the literature

Objectives: Central venous catheter (CVC) implementation is now usual in emergency department. The most common complications are misplacement, bleeding, pleural perforation, thrombosis and sepsis. Forgetting a guide wire in the patient's body after catheterization is an underestimated complication of this procedure; only 76 cases are described. Even if the majority of patients remained asymptomatic, severe complications can happened even years later. This article's aim is to identify the sequence of elements that led to the event occurrence and to suggest recommendations of good practice to minimize complications related to central catheter placement.Method: After reviewing all the complications related to central venous catheterization and their frequencies, we analyse from a case report and a review of the literature the sequence of elements that led to the medical error. We use an Ishikawa diagram to show our results and the links between them.Results: Our Ishikawa diagram shows that material, human resources, procedural and radiological involvement factors are the main elements on which we can act to reduce the complications rate after central venous catheterization. We advocate for the establishment of standardized procedures before, during and after the technical gesture.Conclusions: Because of human nature, errors will always be possible when taking care of a patient. However, we propose good practice recommendations to avoid the repetition of a forgetting guide wire after central venous catheterization.

Complication risk factors related to central venous catheter in pediatric

BACKGROUND

A prospective epidemiological study was carried out in the pediatric intensive care unit (ICU), at the Mayotte Hospital Center (MHC). The purpose of the study was to identify and to evaluate complications risk factors related to central venous catheterization. Improving side effects prevention and patients care was the second goal.

METHOD

Data collection took place over a period of 10 months. The central approaches followed in the study were femoral, jugular and subclavian. Since the database is composed of qualitative and quantitative variables, the Chi² test has been used to measure the association between two variables.

RESULTS

The study was carried out on 101 patients. Five infectious risk factors on the 10 variables evaluated have been significantly highlighted: the number of punctures, the number of repair of the dressing, the duration of the catheterization, the exposure time and the parenteral nutrition administration.

CONCLUSIONS

Evaluation of practices through audits, an appropriate training for the staff, the update and the standardization of procedures, development of standardized assembly of the devices should lower the incidence of complications related to the venous approach.

Inadvertent insertion of a venous catheter into the internal thoracic vein: a word of caution

Central venous catheters are widely used in clinical practice and are linked to many types of complications, including incorrect positioning at the time the catheter is fitted. Here, the authors describe a case in which a fully implantable catheter was inadvertently positioned in the right internal thoracic vein. The complication was identified when the nursing team attempted to use the catheter. The right internal thoracic vein is within the radiographic projection of the right brachiocephalic vein and the superior vena cava, simulating correct catheter placement on an anteroposterior radiograph. In cases of central catheter malfunction during the immediate postoperative period, work-up should include oblique and lateral views, to rule out the complication described here without a need for computed tomography.

Imaging Approach to Misplaced Central Venous Catheters

Central venous catheters (CVCs) are commonly used in patients in a variety of clinical settings, including the intensive care unit, general ward, and outpatient settings. After placement, the radiologist is frequently requested to evaluate the location of CVCs and deem them suitable for use. An understanding of the ideal location of catheter tips as well as the approach to identifying malpositioned catheter tips is essential to prevent improper use, recognize and/or prevent further injury, and direct potential lifesaving care. An approach to CVC placement based on tip location can be helpful in localization and guiding management.

Evidence-Based Strategies and Recommendations for Preservation of Central Venous Access in Children

Children with chronic illness often require prolonged or repeated venous access. They remain at high risk for venous catheter-related complications (high-risk patients), which largely derive from elective decisions during catheter insertion and continuing care. These complications result in progressive loss of the venous capital (patent and compliant venous pathways) necessary for delivery of life-preserving therapies. A nonstandardized, episodic, isolated approach to venous care in these high-need, high-cost patients is too often the norm, imposing a disproportionate burden on affected persons and escalating costs. This state-of-the-art review identifies known failure points in the current systems of venous care, details the elements of an individualized plan of care, and emphasizes a patient-centered, multidisciplinary, collaborative, and evidence-based approach to care in these vulnerable populations. These guidelines are intended to enable every practitioner in every practice to deliver better care and better outcomes to these patients through awareness of critical issues, anticipatory attention to meaningful components of care, and appropriate consultation or referral when necessary.

Adherence to central venous catheter insertion bundle in neonatal and pediatric units

OBJECTIVE

To describe the observed behavior of professionals in two neonatal and pediatric intensive care units regarding the use of central venous catheter insertion bundle, and the clinical and birth profile of neonates and children who received the devices.

METHOD

A quantitative descriptive exploratory study was conducted in two intensive care units of a public hospital in Belo Horizonte with neonates and children, between February and September 2016.

RESULTS

The sample consisted of 59 observed implants of central venous catheter. Most patients were male preterm infants, of cesarean delivery and proper weight according to the gestational age. Among all procedures observed, only three followed all recommendations for the central venous catheter insertion bundle. Incorrect techniques were observed while performing surgical antisepsis and inadequate use of chlorhexidine, an antiseptic.

CONCLUSION

The findings highlight the importance of more investment in continuous training of the team on the prevention of bloodstream infection caused by central venous catheter to reduce the number of adverse events related to intravenous therapy.

A rare case of malposition of central venous catheter detected by ultrasonography-guided saline flush test

Central venous catheter (CVC) insertion is associated with many potential complications; malposition of the catheter is one of them. A chest X-ray is routinely done to detect the malposition of catheter, but sometimes it has been seen that X-ray is time-consuming and its accuracy is also low for determining the exact position of the catheter tip. In our case, an ultrasonography (USG)-guided CVC was placed into the right internal jugular vein of the patient. As there was no ECG change obtained during insertion of guidewire and catheter, malposition was suspected, which was easily detected by a novel USG-guided saline flush test. We present a case report where USG was used for detection of a misplaced CVC (from right internal jugular vein to right subclavian vein). With ultrasound, the location of the catheter tip can be confirmed in very less time compared with chest X-ray.

Central Venous Line Insertion Revealing Partial Anomalous Pulmonary Venous Return: Diagnosis and Management

Central venous line malposition is a well-known complication of line insertion. Rarely, it can be mal-positioned in an anomalous pulmonary vein. We present an unusual case of a 56-year-old woman that was found to have partial anomalous pulmonary venous return on central venous line insertion. In this report, we describe a systematic approach to diagnosis and management of this unusual situation.
