To assess the impact of cardiac motion during percutaneous computed tomography (CT)-guided core needle biopsy (PCT-CNB) of small lung lesions near pericardium, focusing on safety and diagnostic accuracy.
Seventy-eight PCT-CNBs were performed between March 2010 and June 2018 in 78 patients with small (≤ 20 mm) lung nodules, each within 10 mm of pericardium. Shifts in distance and length of interface separating lesions from pericardium were calculated and compared by cardiac chambers (left atrium, left ventricle, right atrium, or right ventricle). Risk factors for complications were subjected to univariate analysis, and diagnostic accuracy was assessed.
The respective mean values were 0.8 ± 1.1 mm (range 0-5.1 mm) for shifts in distance and 1.5 ± 2.1 mm (range 0-10.8 mm) for length of interface. Neither parameter shifted significantly with respect to cardiac chambers (p > 0.05, both). Pneumothorax ensued in 28 patients (35.9%), and pulmonary hemorrhage occurred in 41 (52.6%). The overall sensitivity, specificity, and accuracy of PCT-CNB were 91.2%, 100%, and 93.2%, respectively.
Our data indicate that cardiac motion has no impact on either the incidence of complications or the diagnostic accuracy of PCT-CNB in patients with small (≤ 20 mm) lung lesions near pericardium.
评估心脏运动对经皮 CT 引导下（PCT）经皮肺穿刺活检（PCT-CNB）近心包小肺病变的影响，重点关注安全性和诊断准确性。
2010 年 3 月至 2018 年 6 月期间，对 78 例（78 名患者）小（≤20mm）肺结节患者行 78 例 PCT-CNB，每个结节距离心包均在 10mm 以内。计算并比较各心腔（左心房、左心室、右心房或右心室）时病变与心包之间界面的距离和长度变化。对并发症的危险因素进行单因素分析，并评估诊断准确性。
距离变化的平均值分别为 0.8±1.1mm（范围 0-5.1mm），界面长度变化的平均值分别为 1.5±2.1mm（范围 0-10.8mm）。两个参数均与心腔无明显相关性（p>0.05，均）。28 例（35.9%）发生气胸，41 例（52.6%）发生肺出血。PCT-CNB 的总体敏感性、特异性和准确性分别为 91.2%、100%和 93.2%。
我们的数据表明，心脏运动对近心包小（≤20mm）肺病变患者 PCT-CNB 的并发症发生率或诊断准确性均无影响。
