CVC insertion represents a risk for pneumothorax nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound US guidance and to confirm its utility in clinical practice in cancer patients. Methods Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore mechanical thrombotic infection and malfunctioning. The patient was placed in Trendelenburg s position a MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure an upright chest X-ray and ultrasound scanning were carried
