Drainage is required when preliminary tests such as chest x-rays, ultrasound and CT scans, have shown an abnormal collection of fluid inside your body. There are different reasons to remove this fluid. For instance to find out what it is, what’s causing it, if it is infected (for instance a collection of pus following surgery), causing difficulty breathing or causing discomfort.
This is a minimally invasive way of draining fluid from your body using ultrasound or CT guidance. The procedure is carried out under local anaesthesia.
A preliminary CT or ultrasound scan is carried out. Once the exact needle path has been determined, the radiologist will insert a needle followed by a guide wire and drainage catheter (small plastic tubes about 4mm in diameter) into the fluid. The fluid is then sucked out with a syringe and then the drain is usually attached to an external drainage bag.
