摘要目的评估锥形束(CBCT)引导下经皮穿刺活检纵隔内肿块的诊断准确性及其并发症发生率。方法 75例病人[男38例,女37例;平均年龄:(48.55±18.76)岁]在CBCT引导下经皮穿刺活检纵隔内肿块共78个。对其手术细节、诊断敏感性、特异性、准确性以及并发症发生率进行研究。结果病灶平均大小为(6.80±3.08)cm,皮肤至目标的平均距离为(3.67±1.80)cm,芯针穿刺活检率为96.2%(75/78),留置针留置平均时间为(9.29±4.34)min,全过程平均时间为(13.26±5.29)min,活检标本平均数量为(3.13±1.02)个,CBCT取得活检标本平均数量为(3.03±0.68)个,病灶与邻近纵隔边界识别
Abstract Objective To evaluate the diagnostic accuracy and the incidence of complications caused by percutaneous puncture biopsy of mediastinal masses guided by cone beam (CBCT). Methods Seventy-eight patients (38 males and 37 females, mean age: (48.55 ± 18.76) years) underwent percutaneous biopsy with mediastinal CBCT. The details of surgery, diagnostic sensitivity, specificity, accuracy and incidence of complications were studied. Results The average size of the lesion was (6.80 ± 3.08) cm, the average distance from the skin to the target was (3.67 ± 1.80) cm, the rate of core needle biopsy was 96.2% (75/78) and the average time of indwelling needle was (9.29 ± 4.34 ) min, the average time of the whole process was (13.26 ± 5.29) min, the average number of biopsy specimens was (3.13 ± 1.02) and the average number of biopsy specimens obtained by CBCT was (3.03 ± 0.68)
