Subclavian and Axillary Vein Access Versus Cephalic Vein Cutdown for Cardiac Implantable Electronic Device Implantation: A Meta-Analysis.

OBJECTIVES: This study sought to evaluate the efficacy and safety of venous access techniques for cardiac implantable electronic device (CIED) implantation.

BACKGROUND: Minimally invasive transvenous access is a fundamental step during implantation of CIEDs. However, the preferred venous access is still subject to ongoing debate, and the decision depends on patient characteristics and operator experience.

METHODS: A comprehensive search for studies comparing subclavian vein puncture (SVP) and axillary vein puncture (AVP) versus cephalic vein cutdown (CVC) for CIED implantation was performed in PubMed, Google Scholar, EMBASE, SCOPUS, ClinicalTrials.gov, and various scientific conferences from inception to July 1, 2019. A meta-analysis was performed by using a random effects model to calculate risk ratios (RRs) and mean differences with 95% confidence interval (CIs).

RESULTS: Twenty-three studies were eligible that included 35,722 patients (SVP, n = 18,009; AVP, n = 409; and CVC, n = 17,304). Compared with CVC, SVP was associated with a higher risk of pneumothorax (RR: 4.88; 95% CI: 2.95 to 8.06) and device/lead failure (RR: 2.09; 95% CI: 1.07 to 4.09), whereas there was no significant difference in these outcomes compared with AVP. Acute procedural success was significantly higher with SVP compared with CVC (RR: 1.24; 95% CI: 1.00 to 1.53). There was no significant difference in other complications such as pocket hematoma/bleeding, device infection, or pericardial effusion between SVP or AVP compared with CVC.

CONCLUSIONS: CVC was associated with a lower risk of pneumothorax and lead failure compared with SVP. AVP and CVC are both effective approaches for CIED lead implantation and offer the potential to avoid the complications usually observed with traditional SVP.
