The Seldinger technique is a method of femoral cannulation that has been used to establish cardiopulmonary bypass. Reports of cannulation of the ascending aorta for antegrade perfusion using the Seldinger method are anecdotal. To the best of our knowledge, the approach described herein for direct cannulation of the ascending aorta with use of the Seldinger technique for antegrade perfusion has not been previously described in the English-language medical literature. This method is helpful when the surgeon is treating a patient who has a calcified ascending aorta, complicated aortic dissection, calcified femoral vessels, or a diseased thoracoabdominal aorta. In such cases, retrograde perfusion has been associated with severe complications as a result of atheromatous embolization from the descending thoracic aorta. Herein, we describe our approach to cannulation for cardiopulmonary bypass, which entails insertion of an aortic cannula into the ascending aorta by means of the Seldinger technique. A soft-tip guidewire is inserted through an arterial entry catheter that has been used to puncture a hole in the wall of the vessel. Then the aortic cannula is intro duced into the vessel, sliding along the guidewire. Guided by transesophageal echocardiography, the tip of the cannula is positioned carefully and is then advanced into the descending aorta. This positioning of the cannula decreases the chance of arterial embolization, thereby improving cerebral protection. If cannulation of the ascending aorta is not feasible, the transverse aortic arch or proximal descending aorta can be used.
