Post-Close Technique for Arteriotomy Hemostasis After Impella Removal

Area of Science:

• Cardiovascular Interventions
• Medical Device Technology
• Surgical Techniques

Background:

• Large-bore sheaths are increasingly used with advanced hemodynamic support devices.
• The pre-close technique is standard for hemostasis after device removal but has limitations.
• Failure of pre-close can occur with large arteriotomies (>8 Fr) due to device limitations.

Purpose of the Study:

• To describe a novel "postclose" technique for achieving hemostasis.
• To address challenges in closing large arteriotomies (13-14 Fr) after hemodynamic support.
• To provide an alternative to the pre-close technique in specific clinical scenarios.

Main Methods:

• A "postclose" technique was developed for large arteriotomies (13-14 Fr).
• Two Perclose devices were employed sequentially after device removal.
• The technique was applied after Impella 2.5 or CP system removal from the common femoral artery.

Main Results:

• The described postclose technique provides effective hemostasis for large arteriotomies.
• This method overcomes limitations of the pre-close technique in specific cases.
• Successful application was demonstrated for Impella device removal.

Conclusions:

• The postclose technique is a viable option for managing large arteriotomies after hemodynamic support.
• This approach enhances hemostasis options when standard methods are insufficient.
• Further evaluation may confirm its utility in complex cases.
