Patients with a calcified "porcelain" aorta may also have aortic valve stenosis, necessitating aortic valve replacement to prevent cerebral complications. However, a porcelain aorta can be difficult to open, and ascending aorta repair sutures are almost impossible to insert in a calcified plate. We devised a method of aortotomy using a small oscillating saw, which allowed us to incise the aortic wall cleanly without destruction or the formation of debris. After partial endarterectomy of the calcified plate with aortotomy, closure of the aorta was buttressed with bovine pericardium. During the endarterectomy, we used an elevator designed for hand surgery to exfoliate the calcified intimal plate.
患有钙化“瓷化”主动脉的患者也可能有主动脉瓣狭窄,因此需要进行主动脉瓣置换以预防脑部并发症。然而,瓷化主动脉可能难以打开,而且几乎不可能在钙化的板块上插入升主动脉修复缝线。我们设计了一种使用小型摆动锯进行主动脉切开术的方法,这使我们能够干净利落地切开主动脉壁,而不会造成破坏或形成碎片。在通过主动脉切开术对钙化板块进行部分动脉内膜切除术后,用牛心包加强主动脉的闭合。在动脉内膜切除术期间,我们使用了一种为手部手术设计的剥离器来剥离钙化的内膜板块。
