ANATOMICAL VARIATIONS OF THE INTERNAL JUGULAR VEIN: THE ROLE OF ULTRASONOGRAPHY (original) (raw)
EuroMediterranean Biomedical Journal
Central venous catheterization (CVC) is a common procedure used for long term central intravenous therapy, central venous pressure monitoring, dialysis and apheresys (1-3). The most commonly used technique is percutaneous catheterisation of the internal jugular vein (IJV) which can be found by the identification of an anatomical landmark (Sedillot triangle, formed by medial and lateral heads of the sternocleido-mastoid muscle and base by medial end of the clavicle) ), or by Ultrasonography scanning. The aim of the present paper is to determine the rate of anatomical variations of IJV, in relation with the other structures of the neck, particularly the CCA (4-7), in a cohort of patients who underwent US-guided CVC, in order to underline the importance of anatomical knowledge to reduce the complications related to this procedure, such as difficult or Original Article © EUROMEDITERRANEAN BIOMEDICAL JOURNAL 2014, 9(12):112-117.

This study was aimed to determine by the support of ultrasonography (US) the anatomical variations of the internal jugular vein (IJV) in relation with other structures of the neck, such as the common carotid artery (CCA). Material and Methods: 830 patients requiring central vein catheterization (CVC) were included in the analysis. The position of the IJV in relation to the other structures of the neck was demonstrated by portable ultrasonography.
