Abstract
Background: Leadless pacemakers offer a promising alternative to traditional transvenous pacemakers, especially in patients with complex vascular anatomy or a high risk of infection. Conventional access routes may be compromised in patients with significant venous stenosis or prior vascular interventions, requiring alternative strategies for device implantation.
Case presentation: We report the case of a 74-year-old female with sick sinus syndrome, chronic kidney disease, type 2 diabetes, and severe bilateral iliac vein stenosis, who was deemed high-risk for conventional pacemaker implantation. After failed attempts through both femoral veins, the right internal jugular vein (RIJV) was successfully used as an alternative access route for Micra leadless pacemaker implantation. The procedure was performed under ultrasound and fluoroscopic guidance without complications. Post-procedure, the pacing threshold was 0.75 V, sensing was 8.5 mV, and impedance was 760 Ω, all within normal limits.
Conclusion: This case highlights the feasibility and safety of using the right internal jugular vein as an alternative access route for leadless pacemaker implantation in high-risk patients when femoral access is not possible. This approach provides a valuable option for patients with complex venous anatomy, contributing to the broader application of leadless pacing technology.

International Medical Case Reports Journal is an international, peer-reviewed, open access, online journal publishing original case reports from all medical specialties. Submissions should not normally exceed 3,000 words or 4 published pages including figures, diagrams and references. As of 1st April 2019, the International Medical Case Reports Journal will no longer consider meta-analyses for publication.
