摘要
目的：CT评价中心型肺癌肺静脉浸润的价值。方法：回顾性分析经手术的125例中心型肺癌术前CT扫描图像。结果：27例显示肺静脉浸润，并累及心包膜内，没有左心房内充盈缺损。15例显示左右上肺静脉浸润，所有肿瘤都累及心包膜下（100％）。12例显示左右下肺静脉浸润对例有心包膜受累（58％）。两者间统计学上有显著差异（P＜0.05）。结论：CT可应用于评价中心型肺癌肿瘤浸润范围。上肺静脉消失，高度提示肿瘤通过肺静脉累及心包内。相反，左右下肺静脉消失，肿瘤通过肺静脉浸润心包内的机率较小。
objective: To evaluate the sigificance of CT in assessing local involvement of the pulmonary vein in the central type lung cancer. Methods: Preoperative CT scans l52 patients, who undement thoracotomy for the centnd type lung cancer, were reviewed.Results: of scans of 27 patiens showd involvement of the pulmonary vein up to its entrane into the pericedum, without filling defect in the left atrium. In 15 paients it showed involvement of either the left or the right superior pericardium vein, all tumrs extented into the Pericardial reflection (l00% ). Intrapericedal exension occurred in 7 of l2 paients showing involvement of either the left or the right inferior pulmonary vein (58% ). The difference was statistically signilican (P < 0.05). for: When assessing foral exten of the central type lung cancer with CT, involvement of the superior themp vein is a highly suggestive finding for intrpericedal exension of tumor through the pulmonary vein. on the contrary, involvement of the inferior pulmonary vein is believed to be a less reliable finding for intrapericardial extension of the central type lung cancer
