Superiority of aortic over femoral cannulation for cardiopulmonary bypass, with specific attention to lower extremity neuropathy.

The advantage of aortic cannulation over femoral cannulation in cardiopulmonary bypass has been well established in our experience. Over a four year period, we compared the incidence of complications of these two modalities in a large group of patients. Specific emphasis is placed on the lack of lower extremity neurological deficit and retrograde dissection in patients who underwent aortic cannulation.
