Key result
Femoral artery cannulation for Stanford type A aortic dissection repair was effective, with a 4.5% rate of cerebral events and no lower extremity ischemia.

Does femoral artery cannulation provide safe and effective perfusion in patients undergoing Stanford type A aortic dissection operations?
Retrograde perfusion through the femoral artery is an effective strategy for Stanford type A aortic dissection repair with a low risk of severe cerebral events and lower extremity ischemia.
May support femoral cannulation in type A dissection repair; leaves open optimal strategy pending prospective comparative data.
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.
