This procedure involves inserting a balloon-tipped catheter into the affected vessel and inflating it to widen the passageway, often followed by the placement of a stent to keep the vessel open. Another frequently performed procedure is embolization, where interventional radiologists block blood vessels to stop bleeding, cut off blood supply to tumors, or treat aneurysms. This technique is particularly useful in managing conditions like uterine fibroids and certain types of cancer. Thrombolysis, the dissolving of blood clots, is another critical procedure performed by interventional radiologists. Using catheters, they deliver clot-busting drugs directly to the site of the clot, restoring blood flow and preventing serious complications like pulmonary embolism or stroke. Interventional radiologists also specialize in venous access procedures, such as the placement of central venous catheters or ports for patients requiring long-term intravenous medications or dialysis. These procedures ensure reliable access to the bloodstream while minimizing the risk of infection and other complications. In addition to these, interventional radiologists perform biopsies to obtain tissue samples for diagnostic purposes. Using imaging guidance, they can precisely target suspicious areas and collect samples with minimal invasiveness, aiding in the diagnosis of cancer and other diseases. Drainage procedures are also common, where interventional radiologists insert catheters to drain abscesses, fluid collections, or other blockages in the body. This can provide immediate relief and prevent further complications. Furthermore, interventional radiologists play a crucial role in pain management, offering procedures like nerve blocks and epidural injections to alleviate chronic pain conditions. These treatments can significantly improve the quality of life for patients suffering from debilitating pain.

In oncology, interventional radiologists play a vital role in diagnosing and treating cancer. They perform biopsies to obtain tissue samples for diagnosis and use techniques like tumor embolization and ablation to target and destroy cancerous cells. These procedures can be used to treat liver cancer, kidney cancer, and other types of tumors, often with fewer side effects than traditional cancer treatments. Interventional radiologists also manage liver and biliary conditions. They can place stents to relieve blocked bile ducts, drain abscesses in the liver, and perform transjugular intrahepatic portosystemic shunts (TIPS) to treat portal hypertension. These procedures are essential for patients with liver disease and cirrhosis. In the realm of women's health, interventional radiologists treat uterine fibroids using uterine artery embolization (UAE), a minimally invasive alternative to hysterectomy. They also manage pelvic congestion syndrome, a condition causing chronic pelvic pain, using embolization techniques. Interventional radiologists are also involved in managing bleeding and trauma. They can quickly locate and stop bleeding vessels using embolization, which is critical in trauma situations and in patients with gastrointestinal bleeding. Additionally, they treat pulmonary embolism, a life-threatening condition caused by blood clots in the lungs, using thrombolysis and mechanical clot removal. They also address kidney and urinary tract issues, such as kidney stones and urinary obstructions, using minimally invasive techniques to remove stones and place stents to restore urine flow.
