In Interventional Radiology (IR), biopsy, drainages, and other miscellaneous procedures refer to a group of minimally invasive treatments used to diagnose and treat various conditions. These procedures are commonly performed using imaging guidance such as ultrasound, CT scans, or fluoroscopy to guide the radiologist to the target area. The main goal is to obtain diagnostic samples, drain fluid collections, or treat certain conditions without the need for open surgery.
Minimally Invasive: These procedures typically involve small incisions (or none at all) and are performed under local anesthesia, leading to reduced pain, minimal scarring, and shorter recovery.
Accuracy: Image guidance allows for precise targeting of the area of interest, leading to high accuracy and minimal risk to surrounding tissues.
Lower Risk: Compared to traditional surgery, these procedures carry a lower risk of complications, such as infection, bleeding, or anesthesia-related issues.
Faster Recovery: Most biopsy and drainage procedures are outpatient, meaning patients can typically return home the same day and resume normal activities within a short time.
Versatile Treatment Options: These procedures can be applied to various conditions across multiple organ systems, offering personalized and effective solutions.
Biopsy involves the removal of a small sample of tissue from an abnormal area for diagnostic purposes. This is often used to diagnose cancer, infections, inflammatory diseases, or tumors.
The needle is inserted into the body at the target site, such as liver, lung, kidney, or breast, using imaging guidance (CT, ultrasound, or fluoroscopy). The radiologist then removes a small tissue sample for examination under a microscope to determine the cause of the problem.
Drainage Procedures (Percutaneous Drainage)Drainage procedures are used to remove fluid collections such as abscesses, cysts, or hematomas (collections of blood), often caused by infection, injury, or surgery.
A catheter is inserted through the skin into the fluid collection site, and the fluid is drained out. The catheter may be left in place to allow for continuous drainage until the area is healed.
Drainage for AbscessesAbscesses are localized pockets of infection filled with pus. Drainage is used to relieve symptoms and promote healing. The procedure involves inserting a catheter or needle into the abscess, draining the pus, and often washing out the cavity to reduce the chance of further infection.
Drainage for Biliary Obstruction (Percutaneous Biliary Drainage)For patients with blocked bile ducts (due to conditions such as gallstones, tumors, or infection), a catheter is inserted through the skin to bypass the obstruction and drain the bile. This procedure can help reduce the symptoms of jaundice and infection and improve liver function.
Abscess Drainage (Liver, Kidney, or Abdominal Abscess)Abscesses in the liver, kidney, or abdominal cavity can be drained by image-guided puncture. A needle or catheter is inserted into the abscess cavity, and the infected fluid is drained, alleviating symptoms and reducing the risk of systemic infection.
Other Miscellaneous InterventionsEndovenous Laser Therapy (EVLT): A minimally invasive treatment for varicose veins in which a catheter is inserted into the vein and laser energy is used to seal it off.
Percutaneous Gastrostomy (PEG): Involves the insertion of a tube directly into the stomach for nutritional support in patients who cannot eat normally.
Dialysis Access: Procedures like peritoneal dialysis catheter placement and hemodialysis fistula creation are performed to facilitate dialysis for patients with kidney failure.
