Insights

A rare aortic perforation occurred during off-pump coronary artery bypass grafting using an automatic aortic cutter. This complication led to massive bleeding, requiring emergency surgery and aortic valve replacement.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Techniques
  • Minimally Invasive Cardiac Surgery

Background:

  • Off-pump coronary artery bypass grafting (OPCAB) aims to reduce complications associated with cardiopulmonary bypass.
  • Aortic manipulation during OPCAB, particularly for proximal anastomoses, carries inherent risks.
  • Minimizing aortic cross-clamping is a key goal in OPCAB procedures.

Observation:

  • A posterior aortic wall perforation occurred during routine OPCAB.
  • The complication arose after using an automatic aortic cutter to create a hole in the ascending aorta.
  • This perforation resulted in massive intraoperative hemorrhage.

Findings:

  • The aortic perforation necessitated immediate conversion to cardiopulmonary bypass.
  • Emergency surgical intervention included replacement of the aortic valve and ascending aorta.
  • This case highlights a rare but severe complication of automated aortic cutting devices.

Implications:

  • Enhanced safety protocols and device selection are crucial for OPCAB procedures.
  • Surgeons must be prepared for rare but catastrophic aortic complications during OPCAB.
  • Further research into safer methods for proximal anastomosis in OPCAB is warranted.
