Find your care

Our board-certified physicians diagnose and treat many vascular conditions. Call 310-481-7545 to learn more about interventional radiology services.

Treatment for:

Fluid collections

Why it’s done:

Abnormal fluid collections can be due to infection (abscess), lymphatic damage (lymphocele), leakage of serous fluid, bile or urine (seroma, biloma or urinoma), among other causes. These fluid collections often require drainage for definitive treatment.

How it’s done:

An interventional radiologist uses ultrasound or CT guidance to place a drain into the abnormal collection.

CT guided needle entering an abscess in the abdomen
CT guided placement of needle for drainage of an abscess

Level of anesthesia:

Conscious sedation


Bleeding, infection, damage to surrounding structures


One to two hours of bed rest


Drain output should be monitored, and the drain can usually be removed once symptoms have resolved and drainage has significantly slowed. Drains may require intermittent flushing, depending on the clinical situation.
