Abstract
BackgroundCentral Venous Catheters (CVC) are being used in both intensive care units and general wards for multiple purposes. A previous study Galante et al. (2017) observed that during CVC insertion through Subclavian Vein (SCV) or the Internal Jugular Vein (IJV) the guidewire is sometimes advanced to the Inferior Vena Cava (IVC), and at other times to the right atrium. The rate of IVC wire cannulation and the association with side and point of insertion is unknown.ObjectiveIn this study, we describe guidewire migration location during real time CVC cannulation (right atrium versus IVC) and report the association between the insertion site and side of the CVC and the location of guidewire migration, Right Atrium (RA)/Right Ventricle (RV) versus IVC guidewire migration.MethodsThis is a retrospective study in the medical intensive care unit among patients that have received CVC during the study years 2014–2020. The rate of IVC versus right atrium/right ventricle wire migration during the procedure were analyzed. The association between the side and point of CVC insertion and the wire migration site was analyzed as well.ResultsOne hundred and sixty-six patients were enrolled. 33.7% of wires migrated to the IVC and 66.3% to the versus right atrium/right ventricle. The rate of wire migration to the IVC was similar in the IJV site and the SCV site. There was no association between the side of CVC insertion and wire migration to the IVC.ConclusionAbout a third of all wire migrations, during CVC Seldinger technique insertion, were identified in the IVC, with no potential for wire associated arrhythmia. There was no association between CVC insertion point (SCV versus IJV) nor the side of insertion and the site of guidewire migration.

Summary
Central venous catheters are being used in both intensive care units and general wards for multiple purposes. During CVC cannulation, some complications may occur One of those complications is extra systole or arrhythmia that can be caused due to irritation of the endocardium by the metallic guidewire, especially if the guidewire is inserted to an excessive depth [1, 2]. Central Venous Catheters (CVC) are being used in both intensive care units and general wards for multiple purposes. The rate of IVC wire cannulation and the association with side and point of insertion is unknown
