“…If part of the venous ring remains at the time of IJV formation, the formation of a window of the IJV around these veins could occur, and this anatomical structure is completed when the SAN enters the window [ 13 ]. Few study reports have identified the IJV fenestration; however, the SAN crossed the central part of the IJV and did not pass through the window [ 14 , 15 ]. Moreover, these cases cannot be explained by vascular embryological theory alone.…”

Neck dissection (ND) is a major surgery for head and neck cancer. Currently, some or all of the spinal accessory nerve (SAN), sternocleidomastoid muscle, and internal jugular vein (IJV) are aggressively preserved during ND to reduce postoperative complications. Since the anatomical relationship between the SAN and IJV has several variations, knowledge of these variations is necessary to avoid iatrogenic damage. In the present case, the SAN was observed to pass through the fenestrated IJV at the level of the posterior belly of the digastric muscle during ND in a patient with squamous cell carcinoma of the mandible. Although the anatomical structure of the SAN and IJV is rare, surgeons must be aware of this anatomical variation.

“…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).…”

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

et al. 2022

Central line placement in the internal jugular vein (IJV) can result in complications.Previous studies that examined variations in geometric anatomical parameters in pediatric populations have reduced these risks in children. The aim of this study was to establish possible anatomical variations to improve central line placement in the adult population and demonstrate the use of a correlation heatmap in processing large amounts of data. Twenty-seven volunteers were imaged using ultrasound at three different neck levels on right and left sides and various anatomical parameters were measured. Demographic information was also collected and included in the data processing. The Pearson coefficient was derived from each possible relationship between the measured parameters and was plotted in a correlation heatmap. Strong correlations were observed between the body mass index and the depth of the IJV and common carotid artery (CCA), the relative depth of the IJV to the CCA. No significant correlations were found in the dimensions of both vessels. Anatomical variations were more common than anticipated and should be taken into account when performing central line catheterization in order to minimize post-procedure complications.
