Interventional Radiology Procedures Guide
Interventional radiology procedures are minimally invasive treatments performed using image guidance, such as X-rays, ultrasound, CT, or MRI. These procedures diagnose and treat a wide range of conditions across various organ systems, offering alternatives to traditional open surgery. They typically involve small incisions, leading to less pain, shorter recovery times, and reduced risks for patients.

What are common non-vascular interventional radiology procedures?
Non-vascular interventional radiology procedures focus on treating conditions outside the blood vessels, utilizing advanced image guidance for precise, minimally invasive interventions. These techniques address a broad spectrum of medical issues, from targeted pain management and organ system drainage to diagnostic biopsies, often providing effective alternatives to more invasive surgical approaches. They are crucial for diagnosing diseases, relieving debilitating symptoms, and significantly improving patient quality of life by targeting specific anatomical areas with high accuracy, leading to reduced recovery times and fewer complications.
- Epidural Steroid Injections: Precisely deliver medication into the epidural space to alleviate chronic back and neck pain.
- Biliary Interventions: Address blockages or strictures in bile ducts, including placing stents or performing balloon dilation to restore flow.
- Percutaneous Biliary Drainage: Drains obstructed bile to relieve jaundice and infection, improving patient comfort and health.
- Endoscopic Retrograde Cholangiopancreatography (ERCP): A combined endoscopic and X-ray technique to diagnose and treat problems in bile and pancreatic ducts.
- Transjugular Intrahepatic Portosystemic Shunt (TIPS): Creates a shunt within the liver to reduce high blood pressure in the portal vein, managing complications like variceal bleeding.
- Gastrostomy, Jejunostomy Tube Placement: Provides essential nutritional access for patients unable to eat normally, ensuring adequate feeding.
- Fluid Drainage Procedures: Safely removes abnormal fluid collections, such as abscesses or effusions, from various body cavities under imaging guidance.
- Biopsy: Obtains accurate tissue samples for definitive diagnosis, including fine needle aspiration (FNA) and core needle biopsy techniques.
- Cholecystostomy: Involves placing a tube into the gallbladder to drain bile, often used for acute cholecystitis in high-risk patients.
- Percutaneous Nephrostomy: Drains urine directly from the kidney when the normal urinary tract is obstructed, preventing kidney damage.
- Dialysis Access Procedures: Creates, maintains, or revises vascular access points crucial for patients undergoing hemodialysis treatments.
- Celiac Plexus Block: Administers medication to block nerve signals, providing significant pain relief for severe abdominal pain, often cancer-related.
- Chronic Pain Management: Employs various image-guided techniques to alleviate persistent pain, improving patient function and daily living.
- Pelvic Congestion Syndrome Treatment: Addresses chronic pelvic pain in women by embolizing dysfunctional pelvic veins.
- Central Line Removal/Exchange: Manages and maintains central venous access devices, ensuring their proper function and safety.
How do vascular interventional radiology procedures treat conditions?
Vascular interventional radiology procedures involve diagnosing and treating conditions within the body's intricate network of blood vessels, including both arteries and veins. These highly specialized interventions utilize catheters and wires, precisely guided by real-time imaging, to manage circulatory disorders, clear blockages, and correct vascular malformations. They serve as crucial, less invasive alternatives to open surgery, aiming to restore optimal blood flow, prevent severe complications, or provide necessary access for other medical treatments, significantly reducing patient recovery times and hospital stays.
- Diagnostic Arteriography: Visualizes blood vessels using contrast dye to identify blockages, aneurysms, or other abnormalities, including peripheral, cardiac, and pulmonary angiography.
- Angioplasty and Stenting: Widens narrowed or blocked arteries using a balloon, then places a small mesh tube (stent) to keep the vessel open, such as in carotid or brachiocephalic arteries.
- Percutaneous Transluminal Angioplasty (PTA): A specific technique using a balloon catheter to open narrowed blood vessels, improving blood flow without a stent.
- Embolization: Intentionally blocks blood flow to specific areas, like vascular malformations or bleeding sites, to stop hemorrhage or shrink abnormal growths.
- Catheter-directed Thrombolysis: Delivers clot-dissolving medication directly to a blood clot via a catheter, effectively treating conditions like acute stroke or pulmonary embolism.
- Venous Procedures: Treat various vein conditions, including varicose veins, using techniques like Endovenous Laser Therapy (EVLT), sclerotherapy, and Inferior Vena Cava (IVC) filter placement for clot prevention.
- Central Line Access Procedures: Involves placing specialized catheters for long-term medication delivery, chemotherapy, or dialysis, including Central Venous Catheter (CVC), tunneled, PICC, and implantable port placements.
What interventional radiology techniques are used for tumor treatment?
Interventional radiology offers several advanced, minimally invasive techniques for treating various tumors throughout the body, often serving as an effective alternative or complement to traditional surgery, chemotherapy, or external beam radiation. These procedures precisely target cancerous cells while minimizing damage to surrounding healthy tissue, leveraging sophisticated image guidance for accurate delivery of therapeutic agents or energy. They are particularly beneficial for patients who may not be candidates for conventional surgery or those seeking less aggressive treatment options with faster recovery periods and improved quality of life.
- Radiofrequency Ablation (RFA): Uses heat generated by high-frequency electrical currents to destroy cancerous tumor cells, a common treatment for liver and kidney tumors.
- Cryoablation: Freezes and destroys cancerous tissue using extreme cold, often applied to kidney, lung, and bone tumors.
- Uterine Artery Embolization (UAE): Blocks the blood supply to uterine fibroids, causing them to shrink and alleviating symptoms without surgery.
- Microwave Ablation: Employs microwave energy to rapidly heat and destroy tumors, offering a fast and effective treatment option.
- Transarterial Chemoembolization (TACE): Delivers concentrated chemotherapy drugs directly to a tumor via its blood supply, then blocks the supply to trap the drugs, primarily for liver cancer.
- Selective Internal Radiation Therapy (SIRT): Involves delivering microscopic radioactive beads directly into liver tumors through the hepatic artery, providing targeted radiation.
When are spinal interventional radiology procedures performed?
Spinal interventional radiology procedures are typically performed to treat painful vertebral compression fractures, which are often caused by conditions like osteoporosis, trauma, or metastatic disease affecting the spine. These minimally invasive techniques aim to stabilize the fractured vertebra, significantly reduce pain, and restore patient mobility, offering a substantial improvement in their overall quality of life. They are usually considered when conservative treatments such as bed rest, pain medication, or physical therapy have not provided sufficient relief, allowing for targeted intervention with minimal disruption to surrounding tissues.
- Vertebroplasty: Injects a specialized bone cement directly into a fractured vertebra to stabilize it, providing rapid and effective pain relief.
- Kyphoplasty: Involves inserting a balloon into the fractured vertebra to create a cavity, which is then filled with bone cement to restore vertebral height and stabilize the fracture.
