Abstract

Background: Aortic complications, such as aortic tears and dissections, during cannulation must be managed urgently and often require hypothermic circulatory arrest. We report a unique management strategy to repair an aortic tear without dissection by modifying a Dacron ascending aortic graft with side-arm to serve both as a patch for the aortic tear and inflow for the bypass circuit. Case Presentation: A 32-year-old female patient undergoing reoperative cardiac surgery suffered an unexpected aortic tear during cannulation for cardiopulmonary bypass. After promptly transitioning to femoral cannulation and hypothermic circulatory arrest, the tear was repaired by utilizing a physician-modified ascending aortic graft with side-arm, in which the surrounding skirt of the side-arm was cut from the circumferential graft to patch the defect. The patient was rewarmed with the side-arm serving as arterial inflow for the bypass circuit, and the remainder of the operation proceeded without complication. Conclusion: This type of aortic repair for aortic tears without dissection can offer the patient the benefit of avoiding multiple aortotomies in a weakened aorta, reducing circulatory arrest time, and re-establishing a central cannulation strategy for cardiopulmonary bypass, consequently reducing the likelihood of distal limb ischemia.
