In selected circumstances, such as a type A aortic dissection, aneurysmal enlargement of the ascending aorta or arch, or a porcelain aorta, the same cannula is used to cannulate the axillary or femoral artery, again by the Seldinger technique. In the aforementioned situations, the use of this small cannula, without cross-clamping distal to the insertion point, avoids compromising the antegrade perfusion of the extremity.

We have used this technique in 301 patients undergoing coronary, valvular, and aortic surgery. The overall postoperative stroke rate has been 2% (6 patients) in a high-risk population. From this group, 4 patients (1.3%) had a permanent stroke.

Percutaneous femoral cannulation for cardiopulmonary bypass was first described for use in patients with refractory cardiac arrest.1 We present a safe approach for the antegrade cannulation of a diseased aorta: a cannula with ...
