The ventriculoatrial (VA) shunt is a surgical intervention used to manage hydrocephalus, although it is less often utilized compared to the ventriculoperitoneal (VP) shunt or endoscopic third ventriculostomy. Placement of the distal catheter typically involves the utilization of either the common facial vein (CFV) or the internal jugular vein (IJV), 2 frequently employed options for venous access. This study aims to determine whether there is a statistically significant difference between the long-term patency (2years) of the distal end of the VA shunt of these 2 options. A retrospective cohort analysis was conducted of patients who received VA shunt surgeries with the employment of the CFV or IJV as access veins at Rajavithi Hospital in Thailand between January 2015 and December 2020. The analysis focused on long-term patency and potential complications. The study comprised a total of 42 participants. Twenty-six (61.9%) individuals underwent ventriculoatrial (VA) shunt surgery via the CFV, while the other 16 (38.1%) underwent the same procedure using the IJV. Neither of the 2 groups required shunt revision due to distal catheter malfunction. Most cases exhibited no significant complications apart from a single instance of shunt system infection. In VA shunt surgery, both the CFV and IJV can be used as venous access sites for the right atrium because there is no discernible difference between their complications or long-term patency. Anatomical considerations, patient-specific characteristics, and the surgeon's preference should all be considered when choosing the venous access location for the placement of a VA shunt.
