Angiography and Angioplasty
Angiography is a vital tool in vascular IR. It lets us see inside blood vessels. We inject a contrast agent to spot blockages or abnormalities.
Angioplasty is often done with angiography. A balloon is used to widen narrowed or blocked vessels. This helps restore blood flow.
Stent Placement Techniques
After angioplasty, a stent may be placed. A stent is a small, mesh-like device that supports the vessel walls. It prevents the vessel from narrowing again.
We use different types of stents. Drug-eluting stents release medication to prevent cell growth and reduce restenosis risk.
Embolization Procedures
Embolization blocks blood flow to specific areas. It’s crucial for managing aneurysms, AVMs, and bleeding. We use agents like coils or liquid materials to block vessels.
Embolization can save lives in acute bleeding cases. It can also treat tumors by cutting off their blood supply.
Interventional Oncology Procedures
Interventional oncology has changed cancer treatment for the better. It offers new, less invasive ways to fight cancer. We use advanced imaging to find and treat cancer, making care more effective and quick.
Tumor Ablation Techniques
Tumor ablation kills cancer cells with heat, cold, or chemicals. It’s great for tumors that can’t be removed by surgery or for patients who can’t have surgery.
- Radiofrequency ablation (RFA)
- Cryoablation
- Microwave ablation (MWA)
These methods are guided by imaging, so we can target tumors well and avoid harming nearby tissue.
Chemoembolization and Radioembolization
Chemoembolization and radioembolization send cancer treatment straight to the tumor through the blood. Chemoembolization injects chemotherapy drugs into the tumor’s blood supply and then blocks it. Radioembolization uses tiny radioactive beads to treat the tumor.
