1.Biopsy: Interventional Radiology could be a simple procedure like taking a biopsy. This is done with the ultrasound or CT scanner so that the expert can see the needle. The needle is set perfectly in the tumor and the risk of biopsy is very subdued. The identical procedure can be used to remove pus or blood that has collected in the chest or abdomen. Following CT or US guidance a catheter can be put into the collection. A simple procedure that protects the patient from major surgery.
2.Angioplasty: On the Digital subtraction angiography, the catheter is introduced inside the blood vessel to do the angiogram and can be used to manage many diseases. A blocked vessel can be opened with a catheter with a balloon.
3.Embolization: There are some situations where a vessel must be blocked as part of the treatment. When there are critical bleeding and blood exchange does not support, preventing the blood vessel from the center will save a life. This method is described Embolisation and is the chosen way of using GI bleeds due to Psuedoanerysms.
4.Chemoembolization: This is a way where the cancer medicine is injected right into the blood vessel going into the tumor. The common consequences of using cancer medicines can be avoided and specialists can guarantee that the tumor gets a high dose. This treatment choice is now being given to patients with liver cancer who cannot have surgery.
5.Radiofrequency Ablation: A likely new method for handling small (<4cm) hepatocellular carcinomas and metastasis from colorectal cancer. Radiofrequency Ablation means placing a 16G needle into the lesion under US or CT administration and allowing tumor ablation by heating.
