A calcified porcelain aorta may complicate aortic valve insertion and require an alternative, more complex method for valve replacement. The reason for this is that sutures cannot be inserted through the calcific plates in the annulus and ascending aorta.
In 6 patients with an average age of 73.8 years (range, 65 to 81 years), we performed the simpler procedure of aortic endarterectomy of the calcific plates with the aortic valve replacement. We realized that there may be an increased risk of postoperative complications, particularly stroke. The calcific plates were fractured to allow debridement of the calcium. In addition, an end-arterectomy was performed of the left main coronary ostium in 2 patients, and 5 patients also had coronary artery bypass grafting performed.
All 6 patients underwent successful operations without major complications. On follow-up, echocardiography or computed tomographic scans in 3 patients have not shown dilation of the ascending aorta.
Endarterectomy of the aorta may be an option in the management of patients with calcification of the aorta.
钙化的瓷化主动脉可能使主动脉瓣植入复杂化,需要采用替代的、更复杂的瓣膜置换方法。原因在于缝线无法穿过瓣环和升主动脉的钙化板。
在6例平均年龄为73.8岁(范围65至81岁)的患者中,我们实施了更为简单的切除钙化板的主动脉内膜切除术并进行主动脉瓣置换。我们意识到术后并发症风险可能增加,尤其是中风。将钙化板折断以便清除钙质。此外,2例患者对左冠状动脉开口进行了内膜切除术,5例患者还接受了冠状动脉旁路移植术。
所有6例患者手术均成功,无重大并发症。随访时,3例患者的超声心动图或计算机断层扫描未显示升主动脉扩张。
主动脉内膜切除术可能是主动脉钙化患者治疗的一种选择。
