Do higher levels of IVC clamping increase operative complications and thrombosis risk in patients undergoing IVC surgery?
Higher levels of IVC clamping during surgery are associated with increased operative time, blood transfusions, hospital stay, and postoperative thrombosis, necessitating prompt hemodynamic support and anticoagulation.
Although IVC clamping is a prerequisite for IVC surgery, operative durations, units of RBC transfused, and length of hospital stays increase with higher clamping levels. In addition, CPB use and IVC clamping level are significant risk factors for postoperative thrombosis. In IVC surgery with higher clamping levels, prompt hemodynamic support and proper anticoagulation therapy are important.
