USG Guided Interventions
Ultrasound allows us to detect various abnormalities and perform ultrasound guided diagnostic and therapeutic procedures.
It helps in placing the needle correctly and accurately thereby greatly improving the outcome.
- FNAC (Fine Needle Aspiration Cytology ) : Thin needle is inserted into the abnormal area under sonography guidance and sample is aspirated.
Generally no anaesthesia is required. e.g. Thyroid, neck, breast, liver, pancreas, etc.
- Biopsy : Wide bore needle (automated/semi automated biopsy needle ) is used to obtain tissue core sample from abnormal area. It is more accurate and has higher diagnostic yield. Generally most of the biopsies are done after giving local anaesthesia. General anaesthesia may be required in few cases (unco-opearative or paediatric patients).
E.g. Liver, abdominal mass, breast lump, lymph node, muscle, kidney, etc.
- TRUS (Trans Rectal ultrasound Guided) 12 quadrant prostate biopsy : Generally done to rule out prostate cancer in patients with rising PSA (prostate specific antigen) or with hard prostate on per rectal digital examination. Performed under peri-prostatic block (anaesthesia).
General anaesthesia may be required in few cases (unco-opearative patients).
- Pleural / ascitic / joint fluid / abscess aspiration : Abnormal fluid from chest, abdomen or other body part can be removed for assessment of the same to obtain a diagnosis.
