1. PERCUTANEOUS ABLATION OF TUMORS (RFA AND MICROWAVE)– Percutaneous radiofrequency/ mircowave ablation is an exciting approach to destroying small/ inoperable primary tumors or metastases in the liver, kidneys and certain tumors in bone. It is a simple and minimally invasive procedure done under USG/ CT guidance and thus avoids the morbidity and long recovery periods associated with invasive surgery.
2. TRANS-ARTERIAL CHEMO-EMBOLIZATION/ RADIO-EMBOLIZATION OF TUMORS (TACE/ TARE)– Transcatheter arterial chemoembolization (also called transarterial chemoembolization or TACE) is a minimally invasive procedure performed in interventional radiology done 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. These particles both block the blood supply and induce cytotoxicity, attacking the tumor in several ways. The radiotherapeutic analogue (combining radiotherapy with embolization) is called radioembolization or selective internal radiation therapy (SIRT/ TARE). It is mainly used in the treatment of HCC.
3. PRE-OPERATIVE EMBOLIZATION OF TUMORS– Many of the tumors have a large blood supply including tumors of head, neck, and spine like meningiomas, paragangliomas or glomus tumors, juvenile nasopharyngeal angiofibromas, vertebral body hemangiomas and renal tumors like angio-myolipoma and renal cell carcinomas. This can make surgical removal of these tumors difficult and risky. Pre-operative endovascular embolization of these tumors can be done to reduce intra-/ postoperative blood loss and aid in surgical resection.
