目的 探讨小FOV扫描方法在CT引导下经皮穿刺活检肺小结节(长径≤20 mm)中的应用价值。方法 对104例肺小结节患者分别采用小FOV(n=38,A组)和常规FOV(n=66,B组)行CT引导下经皮穿刺活检,记录病变沿针道距胸膜距离、肺内调整进针次数、手术时间,进针胸膜角等,比较2组肺内出血、气胸的发生率。结果 A组肺内出血总体发生率31.58%(12/38),≥2级肺内出血发生率2.63%(1/38),B组分别为66.67%(44/66)、22.73%(15/66);A组出血发生率明显低于B组(χ2=14.172,P=0.001)。2组肺气肿、病变沿针道距胸膜的距离、手术时间、肺内调整进针次数差异均无统计学意义(P均>0.05)。结论 采用小FOV扫描方法行肺小结节CT引导下经皮穿刺活检可明显降低肺内出血、尤其是≥2级肺内出血发生率。 |

Objective To explore the value of small FOV scanning in CT-guided of transthoracic needle lung biopsy (TTLB) for small pulmonary nodule (≤ 20 mm). Methods CT-guided TTLB was performed in 104 small pulmonary nodules under CT guidance using small FOV (n=38, group A) or common FOV (n=66, group B) scan mode, respectively. The technique and lesion-related variables, including distance to pleura, times of puncture, operating time and pleura-needle angle, etc. were recorded. The incidence of pulmonary hemorrhage and pneumothorax were compared between 2 groups. Results The total incidence rate of pulmonary hemorrhage in group A was 31.58% (12/38), of ≥ grade 2 pulmonary hemorrhage was 2.63% (1/38), while in group B was 66.67% (44/66) and 22.73% (15/66), respectively. The incidence rate of pulmonary hemorrhage in group A was significantly lower than that in group B (χ2=14.172, P=0.001). There was no significant difference of incidence rate of pneumothorax, distance to pleura, times of puncture nor operating time (all P>0.05). Conclusion The incidence rate of pulmonary hemorrhage after CT-guided TTLB for small pulmonary nodule (≤ 20 mm), especially higher-grade (≥ grade 2) pulmonary hemorrhage might be significantly reduced by using small FOV scanning mode. |
