摘要
颈动脉内膜切除术迄今已开展了近50年。但是,尚没有报告描述在这些"内膜切除"标本中动脉中层出现的情况。对来自1997年1月至2003年5月的147份颈动脉内膜切除标本进行了组织学检查。所有的标本中均检出了动脉中层部分。在所有患者中,环状中层的最大含量为从55例(37%)患者中】环状横截面的95%至4例(3%)患者中的≤25%不等。在116例(79%)患者中可见到颈内动脉管周】75%的面积中含有动脉中层。因此,该项手术的更恰当名称似应为"动脉内膜中层切除术",而非"动脉内膜切除术"。
Carotid endarterectomy has been performed now for approximately 50 years. No report, however, has described the presence of media in these ' endarterectomy' specimens. From January 1997 through May 2003, 147 carotid endarterectomy specimens were examined histologically. Portions of arterial media were present in each of them. The maximal amount of circumferential media in any patient varied from >95% of the cross-sectional circumference in 55 patients(37% ) to ≤ 25% of the circumferences in 4 patients(3% ). In 116 patients(79% ), >75% of the arterial circumference of the internal carotid artery contained media. The proper term for this operative procedure might better be ' endomediaectomy' rather than ' endarterectomy.' .
