Ultrasound averts inadvertent injury during internal jugular vein cannulation.

摘要

To the Editor,We report a case where ultrasound imaging (US) was used for internal jugular vein (IJV) cannulation. Not only was US helpful in locating the IJV for central venous catheter (CVC) placement, it also identified a partially occluded IJV.A 17-year-old female patient with a body mass index of 20.7 kg m~(-2) was scheduled for removal of an osteogenic sarcoma from her T6 vertebra. She had undergone surgery one year previously for removal of an osteogenic sarcoma from her maxillary sinus on the left side. As a part of her anesthetic management, we planned to site a CVC in the right IJV under US guidance. After sterile preparation, the anterior triangle of the neck was scanned at a point halfway between the mastoid process and the sternal notch, with a GE Logic-e unit (GE Medical Systems, Wuxi, Jiangsu, China) using a linear 12 MHz transducer. An initial needle puncture was made over the right IJV where the vein appeared fully patent under real time US guidance. The needle was seen to enter the vein, and after free aspiration of blood, a guide wire was passed into the needle. At approximately 3 cm beyond the needle tip threading of the guide wire encountered resistance, and consequently, both the guide wire and the needle were removed. A repeat US scan caudal to the needle insertion site showed a partiallyoccluded LTV with the lumen reducing to less the 2 mm (Fig. 1). The procedure was abandoned on the right side and the CVC was eventually placed in the fully patent left IJV, under US guidance in a single attempt.
