Efficacy and Safety of Percutaneous Venoarterial Extracorporeal Membrane Oxygenation Decannulation Using Endovascular Balloon Dilation and Perclose ProGlide Closure Device: Results from the Multicenter SKYLINE Study.

BACKGROUND

The venoarterial extracorporeal membrane oxygenation (VA-ECMO) cannula can be surgically removed, but postoperative complications and surgical staffing issues can be problematic. We previously reported a method of percutaneously removing the arterial cannula of VA-ECMO by combining intravascular balloon dilation and the Perclose ProGlide (PP) closure device. In this study, we investigated the efficacy and safety of this percutaneous decannulation of the VA-ECMO.

METHODS

This multicenter, retrospective study involved consecutive patients who underwent percutaneous VA-ECMO decannulation at 2 cardiovascular centers from September 2019 to December 2021. We analyzed 37 patients in whom the VA-ECMO cannula was removed by the percutaneous procedure with balloon dilation and the PP. The primary end point was procedural success of hemostasis. The secondary end points were the procedural time, procedure-related complications, and rate of surgical conversion.

RESULTS

The patients' mean age was 65.4 years. The approach site of the endovascular therapy (EVT) procedures were the transradial approach (56.8%), transfemoral approach (27.8%), and transbrachial approach (18.9%). The mean balloon diameter was 7.3 ± 0.68 mm, and the mean balloon inflation time was 14.8 ± 7.3 min. The mean procedure time was 58.5 ± 27.0 min. The procedure success rate was 94.6%, procedure-related complication rate was 10.8%, procedure-related death and postprocedural infection rate was 0.0%, surgical conversion rate was 0.0%, and EVT access site complication rate was 2.7%.

CONCLUSIONS

We concluded that percutaneous VA-ECMO decannulation using a combination of intravascular balloon dilation in EVT and the PP appears to be a safe, minimally invasive, and effective procedure.
