CT引导下经皮肺穿刺活检术并发症发生的影响因素分析

Analysis of Influencing Factors of Complications for CT-guided Percutaneous Lung Biopsy

背景与目的 计算机断层扫描引导下经皮肺穿刺活检术(computed tomography guided percutaneous lung biopsy,CT-PLB)是目前临床广泛应用的肺部病变诊断方式,但其为有创检查,最常见的并发症为气胸和肺出血,严重时可危及生命。本研究旨在分析影响CT-PLB不同并发症发生的独立危险因素,以降低并发症发生率。方法回顾性分析2018年5月至2019年12月于我院行CT-PLB且临床资料完整的605例患者的资料。依病变位置分为胸膜下组和非胸膜下组,根据并发症分为气胸组、肺出血组、气胸合并肺出血组及无气胸/肺出血组,计算各并发症的发生率。分析影响不同并发症发生的危险因素及各并发症的独立危险因素。结果气胸发生率为34.1%,肺出血发生率为28.1%,同时发生气胸及肺出血63例,发生率为10.8%。影响胸膜下组气胸发生的独立危险因素为病变大小(P=0.002)。影响非胸膜下组气胸发生的独立危险因素为穿刺针走行区域平扫CT值(P=0.035)、穿刺针经过肺组织长度(P=0.003)、穿刺针经过胸壁厚度(P=0.020);影响非胸膜下组肺出血发生的独立危险因素为穿刺针经过肺组织长度(P<0.001)、穿刺针走行区域△CT值(P=0.001)、病变大小(P=0.034)及患者体位(P=0.014)。影响气胸、肺出血同时发生的独立危险因素为穿刺针经过肺组织长度(P<0.001)、穿刺针走行区域△CT值(P<0.001)。结论 CT-PLB是一种安全、有效的诊断方式,对肺部占位性病变具有较高的诊断价值,选择合适的穿刺方案可减少气胸、肺出血等并发症,提高诊疗效率。

Background and objective Computed tomography guided percutaneous lung biopsy(CT-PLB)is a widely used method for the diagnosis of lung lesions.However,it is invasive,and the most common complications are pneumothorax and pulmonary hemorrhage,which can be life-threatening in severe cases.Therefore,the aim of this study is to analyze the independent risk factors affecting the occurrence of different complications of CT-PLB,so as to reduce the incidence of complications.Methods The 605 patients with complete clinical data who underwent CT-PLB in our hospital from May 2018 to December 2019 were retrospectively analyzed.According to the location of the lesions,they were divided into subpleural group and non-subpleural group.The patients were divided into pneumothorax group,pulmonary hemorrhage group,pneumothorax with pulmonary hemorrhage group and non-pneumothorax/pulmonary hemorrhage group according to the complications.The risk factors affecting the incidence of different complications and the independent risk factors of each complication were analyzed.Results The incidence of pneumothorax was 34.1%,the incidence of pulmonary hemorrhage was 28.1%,and the incidence of pneumothorax complicated with pulmonary hemorrhage was 10.8%(63 cases).The independent risk factor affecting the incidence of subpleural pneumothorax was lesion size(P=0.002).The independent risk factors affecting the occurrence of pneumothorax in the non-subpleural group were plain scan CT value(P=0.035),length of needle through lung tissue(P=0.003),and thickness of needle through chest wall(P=0.020).Independent risk factors affecting the occurrence of pulmonary hemorrhage in the non-subpleural group were length of needle through lung tissue(P<0.001),△CT value of needle travel area(P=0.001),lesion size(P=0.034)and body position(P=0.014).The independent risk factors affecting the co-occurrence of pneumothorax and pulmonary hemorrhage were the length of needle through lung tissue(P<0.001)and the△CT value of needle travel area(P<0.001).Conclusion CT-PLB is a safe and effective diagnostic method,which of high diagnostic value for lung lesions.Selecting the appropriate puncture program can reduce complications such as pneumothorax and pulmonary hemorrhage,and improve diagnosis and treatment efficiency.
