Introduction: Central venous catheterization is a routine procedure for long-term infusion therapy and central venous pressure measurement. Sometimes, the catheter tip may be unintentionally placed at the position other than the junction of superior vena cava and right atrium. This is called malposition and can lead to erroneous pressure measurement, increase risk of thrombosis, venous obstruction or other life threatening complications like pneumothorax, cardiac temponade.Objectives: This study aimed to observe the incidence of the malposition and compare the same between ultrasound guided catheterization and blind anatomical landmark technique.Methodology: This study was a prospective comparative study conducted at the intensive care unit of Birat Medical College and Teaching Hospital for two-year duration. All the catheterizations were done either with the use of real time ultrasound or blind anatomical landmark technique. The total numbers of central venous catheterization, the total incidences of malposition were observed. Finally the incidences were compared between real time ultrasound guided technique and blind anatomical landmark technique.Results: In two-year duration of the study, a total of 422 central venous cannulations were successfully done. The real time ultrasound was used for 280 cannulations while blind anatomical landmark technique was used for 162 patients. The study observed various malposition in 36 cases (8.5%). The most common malposition was observed for subclavian vein to ipsilateral internal jugular vein (33.3%) followed by subclavian to subclavian vein (27.8%) and internal jugular to ipsilateral subclavian vein (16.7%). In four patients the catheter had a reverse course in the internal jugular vein while the tip was placed in pleural cavity in three cannulations. There was coiling of the catheter inside left subclavian vein in one patient. The malposition was significantly reduced with the use of the real time ultrasound (P< 0.001). However there is no significant difference in the incidence of the various malposition between ultrasound guidance technique and blind anatomical landmark technique when compared individually.Conclusion: The malposition of the central venous catheter tip was common complication with the overall incidence of 8.5%. The most common malposition was subclavian vein to internal jugular vein. The use of real time ultrasound during the catheterization procedure can significantly reduced the risk of malposition.Birat Journal of Health SciencesVol.2/No.3/Issue 4/Sep- Dec 2017, Page: 277-281

Abstract Background and Objective: Detection of radiolucent soft-tissue foreign bodies is a challenging problem, which is especially further complicated when retained foreign body is highly suggested by clinicians but radiography is negative. So, blind exploration is sometimes hazardous for patients. The purpose of this study was to determine the accuracy of ultrasonography (USG) in detecting radiolucent soft-tissue foreign bodies in the extremities. Materials and Methods: From November 2011 to January 2012, patients with clinically suspected radiolucent soft-tissue foreign body and negative radiography were evaluated by USG with a 12-MHz linear array transducer. The patients with positive clinical and USG examination were included in our study and underwent exploration or USG removal. Results: Fifty-one patients underwent foreign body removal under ultrasonography-guided or surgical exploration and 47 patients had foreign body (31, 12, 3, and 1 case had thorn, wood, glass, and plastic, respectively). Ultrasound was positive in 50 patients. USG falsely predicted the presence of foreign body in four cases and was falsely negative in one of the cases. Accuracy, sensitivity, and positive predictive value were determined as 90.2%, 97.9%, and 92%, respectively. Conclusions: The real-time high-frequency USG is a highly sensitive and accurate tool for detecting and removing radiolucent foreign bodies which are difficult to be visualized by routine radiography.

INTRODUCTION: The four main roles of ultrasound in Breast imaging are-primary screening, supplemental screening, diagnosis and Interventional procedures. Palpable masses, abnormal nipple discharge and mammographic abnormalities constitute the most common indication for targeted Breast Ultrasound. AIM: To study the role of Ultrasound in evaluating Breast lesions and characterising them as Benign or Malignant. MATERIAL AND METHODS:This is a Retrospective analysis conducted in Department of Radiology, MGM Medical College and Hospital, Kamothey, Navi Mumbai from February 2021 to June 2021. A total of 136 patients with signs and symptoms related to breast lesions were screened. CONCLUSION: The advent of high frequency probe, easy accessibility, cost effectiveness, reliability and relatively easy to perform makes ultrasound as the prime modality of choice for screening breast lesions.
