Prevention of cholesterol embolism (trash foot) during aorto-iliac reconstruction using a blood filtering device

Area of Science:

• Vascular Surgery
• Surgical Innovation
• Cardiovascular Research

Background:

• Aorto-iliac reconstruction requires cleansing of the aorta and prosthesis to prevent distal embolization.
• The standard "downward flush" method discards potentially valuable blood and may be limited in effectiveness.
• Distal embolization can lead to serious complications such as "trash foot".

Purpose of the Study:

• To present an innovative method for improving the cleansing process during aorto-iliac reconstruction.
• To enhance the effectiveness of preventing distal embolization and associated complications.
• To optimize the "downward flush" maneuver by incorporating a filtering device.

Main Methods:

• A novel filtering device was applied during the "downward flush" in aorto-iliac reconstruction.
• The device allowed flushed blood, containing debris, to be filtered and retained within the distal arterial tree.
• This technique enabled a prolonged and potentially more effective cleansing maneuver.

Main Results:

• The filtering device facilitated the retention of flushed blood, preventing its discard.
• The method allows for prolongation of the cleansing maneuver.
• The overall effectiveness of preventing distal embolization and "trash foot" is potentially increased.

Conclusions:

• The presented filtering device offers a significant improvement over the traditional "downward flush" technique.
• This innovation enhances surgical practice in aorto-iliac reconstruction by improving debris management.
• The method holds promise for reducing the incidence of "trash foot" and improving patient outcomes.
