Name of the Procedure:

Transcatheter Biopsy

• Common Name: Transcatheter Biopsy
• Medical Term: Percutaneous Transcatheter Biopsy

Summary

Transcatheter biopsy is a minimally invasive procedure where a tissue sample is obtained from an organ or lesion using a thin, flexible tube (catheter). This procedure allows doctors to diagnose and evaluate various conditions without the need for traditional surgery.

Purpose

Transcatheter biopsy is used to:

• Diagnose abnormalities in organs such as the liver, kidneys, lungs, or lymph nodes.
• Evaluate suspicious masses or lesions identified on imaging tests.
• Obtain tissue samples for pathology to diagnose infections, inflammatory conditions, or cancers.

Indications

• Unexplained masses or lesions detected via imaging (e.g., CT, MRI).
• Symptoms suggesting organ-specific disease (e.g., liver dysfunction, lung issues).
• Need for tissue examination to guide treatment decisions.

Preparation

• Patients may need to fast for several hours before the procedure.
• Medications such as blood thinners might need to be adjusted.
• Pre-procedure imaging tests (e.g., CT or ultrasound) to locate the target area.
• Blood tests to check clotting function and overall health status.

Procedure Description

1. Anesthesia: Local anesthesia is administered at the insertion site to numb the area. Sedation might be used for patient comfort.
2. Insertion: A catheter is introduced through a small incision in the skin, usually guided by imaging (e.g., fluoroscopy, ultrasound).
3. Navigation: The catheter is navigated through the blood vessels to reach the target organ or lesion.
4. Sample Collection: A special biopsy needle is advanced through the catheter to collect tissue samples.
5. Completion: The catheter and needle are carefully removed. Pressure is applied to the entry site to prevent bleeding.

Tools and Equipment:

• Catheter, biopsy needle, imaging equipment (CT, MRI, ultrasound).

Duration

The procedure typically takes 30 minutes to an hour, but this might vary based on the target organ and patient factors.

Setting

Performed in a hospital's interventional radiology suite, outpatient clinic, or surgical center.

Personnel

• Interventional Radiologist or specialized medical doctor.
• Radiology Technologist.
• Nurses for preparation and post-procedure care.
• Anesthesiologist, if sedation is required.

Risks and Complications

• Common Risks: Minor bleeding, bruising, pain at the insertion site.
• Rare Complications: Infection, major bleeding, injury to nearby organs or blood vessels, allergic reaction to contrast material (if used).

Benefits

• Minimally invasive with a shorter recovery time compared to surgical biopsies.
• Accurate diagnosis leading to appropriate and timely treatment.
• Less pain and lower risk of complications than traditional surgery.

Recovery

• Post-procedure monitoring for a few hours to ensure stability.
• Instructions to rest for 24-48 hours.
• Avoid strenuous activities for a few days.
• Follow-up appointments for results and further management.

Alternatives

• Surgical Biopsy: Involves a larger incision and longer recovery. More invasive but might be necessary if transcatheter biopsy is not feasible.
• Fine Needle Aspiration (FNA): Less invasive but may not provide as much tissue for a comprehensive analysis.
• Imaging Studies Alone: Non-invasive but may not offer conclusive tissue diagnosis.

Patient Experience

• Patients might feel pressure or slight discomfort at the insertion site.
• Pain management includes local anesthesia and possibly mild sedatives.
• Post-procedure, some soreness and minor bruising can be expected.
• Overall, the procedure is well-tolerated and involves minimal pain.
