概括
与固体结节相比,亚固体肺结节的计算机断层扫描 (CT) 引导的皮肤内核针活检 (PCNB) 携带更高的肺出血风险. 由于亚固体结核而接受PCNB的患者需要对这种增加的出血风险进行仔细的咨询.
科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 干预性瘤学干预性瘤学
背景情况:
- 肺结节的特征对于诊断和治疗计划至关重要.
- 计算机断层扫描 (CT) 引导的皮肤穿透核心针活检 (PCNB) 是获得肺组织样本的常用方法.
- 结节密度 (固体,部分固体,非固体) 可能会影响活检结果.
研究的目的:
- 基于肺结节密度的CT引导PCNB的成功率和并发症率进行比较.
- 为了评估诊断准确度和并发症率 (肺胸病,肺出血),按结节类型分层.
- 为了评估这些结果,使用倾向得分匹配 (PSM) 来进行可靠的比较.
主要方法:
- 对1312个CT指导PCNB案件 (2013年3月至2021年3月) 的回顾性分析.
- 病变分为固体 (n=1,120),部分固体 (n=115),非固体 (n=77) 的病变.
- 倾向性得分匹配 (PSM) 用于比较固体与联合亚固体结节 (部分固体 + 非固体).
主要成果:
- 固体,部分固体和非固体结节之间的成功率或肺胸部发病率没有显著差异.
- 整体肺出血率有显著差异 (p<0.001),特别是在固体和部分固体/非固体结节之间.
- 在PSM后,肺出血发生率在亚固体结节 (29.7%) 与固体结节 (8.9%,p<0.001) 相比显著更高.
结论:
- 亚固体肺结节的CT引导PCNB与固体结节相比,肺出血的风险增加有关.
- 临床医生应在接受亚固体结节活检的患者的知情同意过程中强调肺出血的风险.
- 结节密度是评估肺活检潜在并发症时需要考虑的重要因素.

Radiological Investigation I: X-ray and CT
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
