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.

Effective treatment of iatrogenic femoral pseudoaneurysms by combined endovascular balloon inflation and percutaneous thrombin injection

The increasing number of percutaneous endovascular procedures in highly anticoagulated patients has increased the possibility of iatrogenic femoral artery pseudoaneurysm (IFAP). Ultrasound (US)-guided percutaneous thrombin injection is one of the feasible treatments; however, there are concerns about complications such as peripheral embolization. This study was performed to examine the efficacy and safety of treatment of IFAPs using a combination of percutaneous thrombin injection and intravascular balloon inflation. In this retrospective, single-center study, we analyzed 11 patients who developed and were treated for IFAPs from January 2017 through April 2020. The patients were treated with endovascular therapy (EVT) with percutaneous thrombin injection. The technique utilized fluoroscopic guidance to place a balloon at the neck of the IFAP, and the balloon was then inflated to prevent the inflow of blood to the aneurysm. We then performed US-guided thrombin injection. The mean age was 72.36 ± 10.43 years; mean body mass index (BMI) was 25.25 ± 3.18. All patients had hypertension, 72.7% were undergoing hemodialysis, and 54.5% used oral anticoagulant drugs. The mean aneurysm size was 24.34 ± 13.54 mm. The approach was transfemoral in ten patients and transradial in one patient. All procedures were successful, and there were no complications. The mean thrombin dose was 677.3 ± 410.7 IU; the total hemostatic time was 45.4 ± 24.9 min. In conclusion, the combination of percutaneous thrombin injection and endovascular balloon inflation was feasible and safe for the treatment of IFAPs. This technique may contribute to the treatment of IFAPs.

An Effective Method for Percutaneous Removal of Venoarterial Extracorporeal Membrane Oxygenation by a Combination of Balloon Dilatation in Endovascular Therapy and the Perclose Proglide™ Closure Device

BACKGROUND

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can be undertaken surgically, but there are various problems with this method.

METHODS AND CASE REPORT

We removed the arterial cannula of VA-ECMO percutaneously by combining intravascular balloon dilatation and the Perclose ProGlide™ (PP) closure device in a short amount of time and the extent of bleeding was extremely small. Simultaneously, the venous cannula was removed by suturing and manual compression. We report a series of cases of percutaneous removal of VA-ECMO using intravascular balloon dilatation and PP.

CONCLUSIONS

By using this method, VA-ECMO removal was possible in a very short amount of time with minimal invasiveness.
