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


ADVANTAGES


Real-time needle placement


Angled approach (different planes) possible


Color Doppler identifies and avoids the vascular structures in the path


Nonionizing


Minimally invasive with less morbidity


Readily available, relatively inexpensive, and portable


Less time-consuming


DISADVANTAGES


Not suitable for deeper, retroperitoneal structures


Hindrance by the bowel gas


Difficult access in obese patients


PREPROCEDURAL EVALUATION


Coagulation profile should be checked.


Informed written consent.


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


POSTPROCEDURAL EVALUATION


Monitor patient’s vitals


Reimaging for proper procedure


THORACOCENTESIS


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
