    What is Usg Guided Biopsy?

    USG guided biopsy is a minimally invasive procedure in which ultrasound is used to locate a lesion and guide a needle to obtain tissue for histopathology.

    Common Sites

    Liver Lesion

    Renal Mass

    Other Lesions

    • Lymph nodes, Soft tissue masses, Ascites, Thyroid nodules, Spleen etc.

    PROCEDURE TECHNIQUE: STEP BY STEP

    USG-GB

    01. Patient Preparation

    1

    Explain procedure and take consent.Check coagulation profile.Patient in comfortable supine/prone/lateral position.

    Jan

    02. Ultrasound Evaluation

    2

    Scan to locate the lesion.Choose the safest needle path avoiding vessels & organs.

    Jan

    04.Needle Insertion under USG

    4

    Introduce the biopsy needle in real-time USG guidance.Advance carefully into the lesion

    Jan

    05. Tissue Sampling

    5

    Obtain tissue using core biopsy needle or FNAC needle.Multiple samples if required.

    Jan

    06.Post Biopsy Care

    6

    Withdraw needle.Apply pressure.Observe patient for 2–4 hours (as needed).Advise rest and follow-up.

    Jan

    Contraindications

    • Uncorrected coagulopathy ( 1NR > 1.5 , platelets < 50,000/L)
    • Uncooperative patient
    • Local infection at puncture site
    • Lack of safe access window
    • Severe cardiopulmonary instability
    • Vascular lesion (unless specifically indicated and under expert guidance)
    • Pregnancy (relative, depending on indication)

    ADVANTAGES

    Real-time imaging guidance
    Minimally invasive
    Safe, quick and well tolerated
    No radiation exposure
    High diagnostic accuracy
    Outpatient/day care procedure
    Cost-effective
    Multiple sites can be biopsied

    Indications

    Liver

    • Focal liver lesions (benign/malignant)
    • Diffuse liver disease (e.g. hepatitis, fibrosis)
    • Suspected liver metastasis
    • Unexplained liver dysfunction

    Renal

    • Renal masses/tumors
    • Suspected renal cell carcinoma
    • Infections (abscess, TB)
    • Rejection in renal transplant

    Others

    • Lymphadenopathy
    • Soft tissue masses
    • Ascites (diagnostic tap)
    • Thyroid nodules
    • Spleen lesions

    Usg Guided Biopsy - Common Lesions

    Liver Lesion

    Retroperitoneal Node

    Lymph Node

    Soft Tissue Mass

    Potential Complications

    Liver

    • Pain
    • Bleeding/hematoma
    • Hemobilia (rare)
    • Infection
    • Injury to adjacent organs (very rare)

    Renal

    • Hematuria
    • Perirenal hematoma
    • Arteriovenous fistula (rare)
    • Pain
    • Infection

    Others

    • Bleeding
    • Infection
    • Organ injury (rare)

    Types of Needles

    FNAC Needle (226/23G)

    Core Biopsy Needle (18G/16G)

    Automated Biopsy Gun

    Tissue Samples

    Key Points

    • Choose the shortest and safest needle path.
    • Avoid interposed vessels and bowel loops.
    • Use real-time USG throughout the procedure.
    • Apply firm pressure after biopsy to prevent bleeding.
    • Monitor patient and vital signs after the procedure.

    Important Advice

    • USG guided biopsy is a safe, accurate and effcemod obtain tissue diagnosis from various organs and lesions when performed by skilled hands with proper patient selection and technique.
