A modified technique of atriofemoral bypass for visceral and distal aortic perfusion in thoracoabdominal aortic surgery.
Modified atriofemoral bypass (AFB) was used for repair of thoracoabdominal aortic aneurysms (TAAA). The primary circuit consisted of a centrifugal pump and heat exchanger to perfuse and warm the systemic circulation. A parallel secondary circuit with a second heat exchanger perfused the viscera with cold blood. A progressive sequential cross-clamping technique was used. This technique offers theoretical hemodynamic and metabolic advantages and may prove to be useful in preventing ischemic and reperfusion injury to the spinal cord and kidneys.
