肺针活检是获得很小的肺组织样本的程序。然后使用显微镜检查组织。

This technique is used to diagnose an irregular area of tissue in your lungs. A needle biopsy is also called percutaneous needle aspiration.

Your doctor may perform a lung needle biopsy to investigate an abnormality found during achest X-ray, aCT scan, oranother imaging test.

Your doctor can use this procedure to:

A lung needle biopsy may be performed on its own or with other tests, such as:

  • 支气管镜检查。In a支气管镜检查, an instrument with a camera on its end is inserted into your throat through your mouth, and then into the airways in your lungs. This allows your doctor to view various parts of your lungs.
  • Mediastinoscopy.In a纵隔镜检查，通过胸部的切口插入带有光线的仪器。您的医生使用纵隔镜来查看肺之间的区域。之后，他们收集淋巴结组织用于检测。

确保您告诉医生您是否怀孕，可能怀孕或最近患病。

Also tell your doctor about all of the medications you’re taking, both over the counter and prescription. You may be told to avoid taking some medications for a period of time before your procedure, including:

  • 非甾体类抗炎药（NSAID），例如布洛芬（Advil，Motrin IB）和阿司匹林
  • some blood thinners, such as warfarin (Coumadin)

您将进行活检的设施中的某人会在手术前打电话给您以确认时间和位置。可能会告诉您在活检前至少6到8个小时避免进食或饮酒。

A specialist known as an interventional radiologist usually performs the biopsy with the aid of a CT or other type of scan.

活检之前

The radiologist indicates the exact spot where the needle should be placed by drawing on your skin with a marker.

您可能将静脉注射线插入一只手臂或手中的静脉中。这用于提供镇静剂让你困了。

技术人员或护士可以帮助您进入正确的位置。他们用防腐剂清洁活检部位的皮肤。然后他们向您注入麻药麻木区域。这可能刺痛。

在活检期间

Your radiologist will generally use a biopsy needle that’s several inches in length. The design of the needle — hollow and wider than those used for regular shots — is what allows them to obtain a tissue sample.

可以在您的皮肤中切开一个小切口，以便轻松插入活检针头。插入多少针取决于异常肺组织的位置。然后，您的放射科医生采集异常组织的样品。这可能会感觉像压力甚至急性疼痛。

You’ll be asked to remain still and avoid coughing during the biopsy. When your radiologist is ready to remove a tissue sample, you’ll need to hold your breath. Several samples may be required.

活组织检查后

Once the biopsy is done, the needle is removed. Pressure is applied to the insertion site to help control any bleeding. When the bleeding has stopped, the site is bandaged. Sometimes one or more stitches are required if an incision is made. A typical lung needle biopsy is usually completed in less than 60 minutes.

The tissue samples will be sent to a laboratory for testing.

肺针活检通常是安全的。但是，与任何程序一样，存在风险。对于肺针活检，其中包括：

活检后，技术人员和护士将监视您是否有任何并发​​症的迹象。活检完成后，您可能不久就可以离开该设施。

与您的医生谈谈在返回工作或上学之前应该休息多长时间。还要询问任何限制，例如举重或重型运动。

If you were sedated

If you were sedated, it may take a day or so to recover from the medication. In this case, plan to have a friend or relative drive you home. Once you’re home, they should also stay with you until you’re fully awake.

如果你痛苦

您可能需要一些止痛药来控制活检后的不适。

避免使用NSAID，因为它们可能会增加您出血的风险。取而代之的是非阿斯皮素止痛药，例如对乙酰氨基酚（泰诺）。

Your doctor may also order a prescription pain reliever.

什么时候打电话给你的医生

您可能会咳嗽少量的血液。如果这与您有关，请致电您的医生。

如果您在活检后有以下任何症状，请致电医生：

  • 活检部位出血
  • 活检部位的发红或排水
  • 咳嗽超过少量血液
  • difficulty breathing
  • 胸痛
  • fever

Once the tissue samples are examined, a report will be sent to your doctor, who will contact you with the results. They may receive the report quickly, or it may take a few days. Results are typically ready in 2 or 3 days, though.

Depending on the findings, your doctor may order additional tests. Once they determine a diagnosis, they may suggest a treatment plan or refer you to other specialists.
