The optimal cannulation site in repair of DeBakey type I aortic dissection is controversial, and malperfusion during cardiopulmonary bypass is facilitated by retrograde flow. We propose the use of a long arterial cannula through the femoral artery to achieve a proximal antegrade perfusion. The tip of the cannula is placed in the true lumen of the distal aortic arch through the common femoral artery (Seldinger technique and transesophageal echography guidance). In 9 patients, there was one case of operative mortality (cardiac death), and no cases of perioperative stroke, bowel ischemia, severe renal failure, or local complications. Proximal perfusion can achieved rapidly and through an easily accessible site.
在修复 DeBakey Ⅰ型主动脉夹层时,最佳的插管部位存在争议,体外循环期间的逆行血流会导致灌注不良。我们建议使用通过股动脉的长动脉插管来实现近端顺行灌注。通过股动脉将插管尖端置于降主动脉远端真腔中(Seldinger 技术和经食管超声心动图引导)。在 9 例患者中,有 1 例(心脏死亡)手术死亡,无围手术期卒中、肠缺血、严重肾衰竭或局部并发症发生。近端灌注可以通过易于接近的部位快速实现。
