The Use of a Handheld Ultrasound Device to Guide the Axillary Vein Access during Pacemaker and Cardioverter-Defibrillator Implantation. A Feasibility Study.

BACKGROUND

Although ultrasound guidance for axillary vein (AV) access (USGAVA) has been described as a reliable technique for cardiac implantable electronic device (CIED) implantation, no data is available on the use of handheld ultrasound devices (HUD) in such a setting.

OBJECTIVE

We investigated the feasibility of using a HUD for USGAVA in patients referred to our Institution for CIED implantation.

METHODS

The procedure details of 80 consecutive patients undergoing USGAVA (Group-1) from June 2020 to June 2021 were prospectively collected and compared to those of an age and sex-matched cohort of 91 patients (Group-2) who had undergone AV access with the traditional venipuncture guided by fluoroscopic landmarks.

RESULTS

The two groups were comparable for the success rate of venous access (92.5% versus 93.4%, = 0.82), complication rate (1.3% versus 0.9%, = 1.0), and procedure time (71 32 min versus 70 29 min, = 0.9). However, Group-2 had a longer X-ray exposure time (7.6 8.4 min versus 5.7 7.3 min, = 0.03). In Group-1, the univariate logistic regression analysis demonstrated that the AV diameter was associated with successful USGAVA (odds ratio = 3.34, 95% confidence interval 1.47-7.59, 0.01), with a 3-fold increase of probability of success per each 1 mm increase in the AV diameter.

CONCLUSIONS

USGAVA using a HUD for CIED implantation is a feasible, effective, and safe technique; moreover, it saves X-ray exposure time without lengthening the implant procedure time.
