Femoral artery cannulation in Stanford type A aortic dissection operations.

The aim of this study was to evaluate femoral artery cannulation in Stanford type A aortic dissection operations. Between March 1994 and December 2001, 88 patients with Stanford type A aortic dissection underwent surgery with cardiopulmonary bypass and perfusion through the femoral artery; 31 of them had deep-hypothermic circulatory arrest. False lumen perfusion was detected in 8 patients (9.1%). There were 4 (4.5%) cerebral events: 2 patients had diffuse cerebral injury, with one death; and 2 patients had hemiplegia, with one death. Six patients (8.0%) had delayed incision healing, with local infection in one. There was no lower extremity ischemia associated with femoral artery cannulation. It was concluded that retrograde perfusion through the femoral artery was effective for repair of aortic dissection, with a low risk of those cerebral events associated with a high mortality rate.
