Variaciones de la relación anatómica de la arteria carótida común y la vena yugular interna. Estudio ecográfico

Abstract

Introduction: The internal jugular vein locates anterior or anterolateral to the common carotid artery in two-thirds of the subjects studied by ultrasound when the head is in a rotated position. Aim: To identify variables associated with the anterior location of the internal jugular vein. Methods: Ultrasound examinations were performed with the patients in the supine position, with the head rotated to the opposite side. The proximal third of the neck was visualized transversely with a 7.5-mHz transducer. The relationship between the vessels was described in accordance with the proportion of the artery overlapped by the vein. Univariate comparisons and a multivariate analysis of potential variables that may affect the anatomic relationships were performed. Results: Seventy-eight patients were included, 44 of whom were men. The patients' ages ranged from 17 to 90 years (median 64.0, interquartile range 41-73). The right and left sides were studied 75 and 73 times, respectively. The vein was located lateral to the artery in 24.3% (95%CI= 17.4-32.2) of the studies, anterolateral in 33.8% (95%CI= 26.2-41.4) and anterior in 41.9% (95%CI= 33.9-49.8). The multivariate analysis identified age group (OR= 3.7, 95% CI 2.1-6.4) and, less significantly, the left side (OR= 1.7, 95%CI= 0.8-3.5) and male gender (OR= 1.2, 95%CI= 0.6-2.7) as variables associated with the anterior position of the vein. Conclusión: The anterior position of the internal jugular vein relative to the common carotid artery increases gradually with age. Additionally, left-sided localization and male sex further increased the probability of an anterior position.

Anatomical variations of the internal jugular vein in the context of central line placement: A visual approach to data processing

“…Current guidelines for central venous access encourage the use of ultrasound guidance but do not consider the variability of the positions and dimensions of the vessels (American Society of Anesthesiologists, 2020). Previous research has suggested at least five variations in positioning between the IJV and the CCA, with the IJV anterior overlapping the CCA in only 35.8% of the sample (Umaña Perea et al, 2015). This study has further investigated geometrical measures of the vessels and found that the depth of the right IJV more closely correlates with the individual's BMI than the depth of the left IJV (Table 1).…”

“…Previous studies in adult populations attempted to characterize the fenestrations in the IJV (Abakay et al, 2019; Mumtaz & Singh, 2019; Pegot et al, 2015) and positional variations of the IJV (Lorchirachoonkull et al, 2012; Umaña Perea et al, 2015); geometric parameters and modeling have mainly been studied in pediatric populations (Lee et al, 2017). More specifically, there has been an effort to determine the optimal depth of the IJV for central line placement, both in pediatric and adult populations (Kim et al, 2012).…”

Deep learning‐based ultrasonic dynamic video detection and segmentation of thyroid gland and its surrounding cervical soft tissues

“…IJV may differ due to anatomical differences, the movement of head, or the position of probe. 29 Second, IJV wall is thinner than CCA. The probe is slightly under pressure and IJV is prone to deformation, thus making the diameter and cross-sectional area to become smaller or disappear.…”

Remote physiological monitoring of neck blood vessels

“…The discrepancy in ROI selection and individual anatomy differences can also cause inconsistent correlation results. Umaña et al found that about 41.1% of the observations show that the internal jugular vein was significantly overlapped with a carotid artery on the left side of the neck 32,33 . Furthermore, the lateral position of the internal jugular vein was approximately 26.5% on the left side of the neck 32,33 .…”
