Catheter-directed therapy is a minimally invasive treatment approach that involves the use of a catheter to deliver targeted therapies directly to the affected area within the body. This can include procedures such as catheter-directed thrombolysis for the treatment of blood clots, catheter-based angioplasty to treat narrowed or blocked blood vessels, and catheter-based embolization to block blood flow to tumors or abnormal vessels. Catheter-directed therapy is often used in interventional radiology and cardiology procedures, offering a less invasive alternative to traditional surgery with shorter recovery times and fewer complications.
