USG-Guided Interventions

USG-Guided Interventions

1.    Thoracocentesis—Chest tap—Pleural effusion tapping

2.    Paracentesis—Ascitic fluid tap

3.    Cyst aspiration

4.    Percutaneous abscess drainage

5.    FNAC/Biopsy—Breast, liver, kidney, lymph node, and any peripheral superficial structure

6.    Vascular access

7.    Suprapubic catheterization


Real-time needle placement

Angled approach (different planes) possible

Color Doppler identifies and avoids the vascular structures in the path


Minimally invasive with less morbidity

Readily available, relatively inexpensive, and portable

Less time-consuming


Not suitable for deeper, retroperitoneal structures

Hindrance by the bowel gas

Difficult access in obese patients


Coagulation profile should be checked.

Informed written consent.

Prior USG to choose the short possible route, avoiding the adjacent crucial structures.


Monitor patient’s vitals

Reimaging for proper procedure


Both diagnostic and therapeutic

Done in sitting or lateral decubitus position with the affected side up

Transducer should be perpendicular to the chest

Marker on the probe should point toward the head

Identify diaphragm, liver, spleen, and lung

Locate the largest pocket of fluid and mark it

Note the distance from the transducer to the pleural fluid
