目的：探讨CT定位导引下氩氦刀治疗胸部肿瘤的可行性、安全性及疗效评价。方法：36例经病理证实的胸部肿瘤（41处病灶）在CT定位导引下经皮行氩氦刀冷冻消融治疗，术后计算冰球覆盖率，统计数据采用x2检验进行差异显著性检验，P＜0．05认为差异有显著性。结果：冷冻消融治疗后，胸部肿瘤病灶呈球形低密度，CT值均明显下降；最大径小于3cm、3cm～5cm、大于5cm的肿瘤冰球覆盖率分别为96．3±1．9、84．2±2．8、60．1±3．6，前2组与第3组的冰球覆盖率差异有统计学意义（P＜0．05）；并发症发生率13．8％（5/36）：其中气胸3例，肺出血2例。结论：氩氦刀冷冻消融治疗胸部肿瘤是一种安全、有效的治疗方法，治疗效果明显，在CT准确定位下，手术并发症发生率低，具有较高的临床应用价值。

Purpose:To investigate the feasibility, safety and efficacy evaluation for the treatment of thoracic neoplasm by CT guided AHCS (argon-helium cryosurgery system).Methods:36 patients (41 lesions) with pathologically confirmed thoracic neo-plasm were treated in CT guided AHCS and then calculated ice hockey coverage ratio.All statistical data were analyzed mainly through the x2 test.Difference were considered to be statistically significant if P<0 .05 .Results:After cryoablation therapy, breast neoplasm were spherical with low density, the CT values were significantly decreased.The maximum tumor diameter of less than 3cm,3cm ~5cm, greater than 5cm hockey coverage rate was 96.3 ±1.9, 84.2 ±2.8, 60.1 ±3.6,respectively Hockey coverage of the first two groups and the third group difference was statistically significant (P<0.05).Complication rate of 13.8%(5/36):pneumothorax in 3 cases, pulmonary hemorrhage in 2 cases.Conclusion:The treatment of thoracic neoplasm by CT guided AHCS might be a safe and effective method of treatment, the accurate positioning of the CT-Pinpoint location system, the low incidence of complications, with a high clinical value.
