This report describes a surgical approach of aortic valve replacement in a patient with a calcified ascending aorta, calcified aortic valve stenosis and coronary artery disease. The aortic valve was replaced with a 19 mm St. Jude Medical prosthetic valve through the transected aorta while the distal ascending aorta was cross-clamped at a narrow but not calcified band approximately 4.5 cm distal to the aortic anulus. These procedures were successfully done and no neurological deficit was found after surgery. The aortic valve replacement through the transected aorta may be one of the alternatives in selected patients with porcelain aortas and calcified aortic valves.
本报告描述了一名患有升主动脉钙化、主动脉瓣狭窄和冠状动脉疾病患者的主动脉瓣置换手术方法。通过横断主动脉，用一个19毫米的圣犹达医疗人工瓣膜替换主动脉瓣，同时在主动脉瓣环远端约4.5厘米处一个狭窄但未钙化的部位对升主动脉远端进行交叉钳夹。这些手术均成功完成，术后未发现神经功能缺损。对于选定的患有瓷化主动脉和钙化主动脉瓣的患者，经横断主动脉进行主动脉瓣置换可能是一种选择。
