摘要
目的 探讨纵隔病变的不同穿刺途径的临床应用及并发症处理。方法 经X线平片和CT发现的 5 1例纵隔肿块样占位病变 ,在CT引导下采用不同的穿刺途径 ,包括 :①直接 ;②经肺 ;③经胸膜腔途径。用细针抽吸切割方法取样 ,标本块用 10 %甲醛溶液固定 ,病理切片观察。结果 5 1例纵隔病变 ,刺中率 90 .1% (4 6 /5 1) ,正确率88.2 % (4 5 /5 1) ,假阴性率 11.8% (6 /5 1) ,无假阳性发现。穿刺病理结果 ,恶性病变占 72 .5 % ,并发症 ,气胸 4例占 7.8% ,肺内出血现象 3例占 5 .9% ,1例伤及内乳血管。结论 ①CT是目前纵隔病变穿刺活检的最佳手段。②纵隔病变穿刺活检多采用直接和经肺途径。③并发症一般不严重 。
Objective To evaluate the clinical applications of alternative approaches to CT guided fine needle biopsy of mediastinal lesions and the disposed complications. Methods The alternative approaches under CT guidance were adopted for X ray or CT images of 51 cases with mediastinal mass like lesions, including: ① direct approach, ② approach traversing lung, ③ approach traversing pleural cavity. Samples obtained with fine needle aspirating and cutting were fixated in 10% formalin, and observed in pathological histology. Results Punctur rate 90.1%(46/51), accuracy rate 88.2%(45/51), false negative rate 11.8%(6/51), without false positive in the cases. Pathologically, the malignancy 72.5%. Complications, pneumothorax 7.8%(4 cases), intrapulmonary hemorrhage 5.9%(3cases),internal mammary vessels injured (1 case). Conclusion CT is the best guided method in biopsy of mediastinal lesions. ② Direct and traversing lung were performed constantly in biopsy of mediastinal lesions. ③ The Complications were not serious, and disposed in clinic.
