Vascular and Interventional Radiology Procedures
Vascular and interventional radiology (VIR) procedures are an essential part of modern healthcare, offering minimally invasive alternatives to traditional surgical interventions. These procedures utilize a range of medical instruments, including catheters and wires, guided by advanced imaging technologies such as CT scans, ultrasounds, and fluoroscopy. The use of these techniques allows for precise and targeted treatment, reducing risks and promoting faster recovery.
The main benefit of VIR procedures is their minimally invasive nature, which means smaller incisions, shorter hospital stays, and reduced discomfort for patients. Let’s take a closer look at some common VIR procedures:
- Ablation: This procedure involves the destruction or removal of abnormal tissue, such as tumors or problematic veins, using various energy sources.
- Balloon Angioplasty: In this procedure, a catheter with a deflated balloon is inserted and inflated to open narrowed or blocked blood vessels.
- Embolization: Embolization is the deliberate blockage of blood vessels to treat conditions such as bleeding or to cut off the blood supply to tumors.
- Sclerosis: Sclerotherapy is commonly used to treat varicose veins by injecting a solution directly into the affected vein, causing it to shrink and eventually disappear.
- Stent Placement: Stents, small expandable tubes, are inserted into blood vessels to help keep them open, improving blood flow and preventing blockages.
These procedures, along with others performed by vascular and interventional radiologists, offer patients less invasive options and can often be done on an outpatient basis. By combining advanced imaging technologies with skilled medical professionals, VIR procedures continue to advance the field of medicine and provide patients with safer, more effective treatment options.
