Embolization of a tumor can be done for various purposes, including preoperative embolization, definitive embolization, and embolization for tumoral bleed.
Preoperative embolization is often used to shrink or devascularize the tumor before surgery, making it easier to remove and reducing the risk of bleeding during surgery. This is often done for tumors that are highly vascular, such as kidney or liver tumors.
Definitive embolization, on the other hand, is a treatment option for tumors that cannot be surgically removed or for patients who are not suitable candidates for surgery. This involves blocking or reducing blood flow to the tumor using embolic agents, causing the tumor to shrink over time. This may be used in cases where the tumor is causing symptoms or is at risk of growing and spreading.
Embolization for tumoral bleed is a technique used to stop bleeding from a tumor. This can be a life-saving procedure in cases where the bleeding is severe and cannot be controlled using other methods. The embolic agents are used to block the blood vessels supplying the tumor, stopping the bleeding.
The embolization procedure involves the insertion of a catheter into the blood vessels supplying the tumor, usually via the groin or wrist. Embolic agents, such as tiny beads or coils, are then injected into the blood vessels, blocking or reducing blood flow to the tumor.
Embolization can be an effective treatment option for certain types of tumors, but it is not suitable for all patients. The decision to undergo embolization should be made in consultation with a team of experienced doctors, who can evaluate the patient’s individual situation and determine the most appropriate treatment plan.
