Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
Anne Christine Roberts is an American interventional radiologist who is credited with the invention of the Roberts Uterine Catheter (RUC), a catheter designed to facilitate navigation through the uterine arteries and currently used widely for uterine artery embolization procedures. [1]
Once a catheter is in place, it can be used to perform a number of procedures including angioplasty, PCI (percutaneous coronary intervention) angiography, transcatheter aortic valve replacement, balloon septostomy, and an electrophysiology study or catheter ablation.
The Seldinger technique is used for angiography, insertion of chest drains and central venous catheters, insertion of PEG tubes using the push technique, insertion of the leads for an artificial pacemaker or implantable cardioverter-defibrillator, and numerous other interventional medical procedures.
Melvin Paul Judkins (May 3, 1922 – January 28, 1985) was an American physician known for his pioneering contributions to the field of radiology, with techniques and devices that played a part in the early development of the fields of interventional radiology and interventional cardiology.
Uterine artery embolization (UAE, uterine fibroid embolization, or UFE) is a procedure in which an interventional radiologist uses a catheter to deliver small particles that block the blood supply to the uterine body. The procedure is primarily done for the treatment of uterine fibroids and adenomyosis.
In modern interventional cardiology the procedural success rates are high and ischemic complications are relatively rare. However the bleeding complications associated with transfemoral catheterization have not been significantly reduced even after the introduction of new pharmacological strategies.
