A Closer Look at Tumor Embolization

Tumors require a good supply of blood from blood vessels to grow. Tumor embolization targets those vessels directly, using image-guided techniques to block the blood supply. This approach can be used to treat liver tumors, kidney cancers, and uterine fibroids, among others.

For patients who aren’t candidates for surgery, or who need a treatment boost before chemotherapy or radiation, embolization provides another option with proven results.

Third Coast Vascular specializes in minimally invasive procedures that treat a full range of vascular conditions. Our physicians offer embolization techniques on-site at our Sheboygan and Milwaukee locations. With a focus on safety, precision, and long-term outcomes, our team works closely with patients to design personalized, effective care plans.

How tumor embolization works

Embolization involves making a small puncture, typically in the groin or wrist. A catheter is guided through the blood vessels to reach the arteries that feed the tumor. Once in position, the physician releases embolic material, such as beads, foam, coils, or medical glue to block those vessels. 

The result is reduced blood flow, less oxygen delivery, and a slower-growing or shrinking tumor.

Blocking the tumor’s blood supply can also improve the effectiveness of radiation and chemotherapy. By limiting blood flow, embolization helps trap chemotherapy drugs near the tumor and increases their impact.

Common uses and conditions treated

Tumor embolization is often used for: 

• Liver tumors (primary or metastatic)
• Renal cell carcinoma
• Bone tumors
• Uterine fibroids (in a procedure called uterine fibroid embolization)
• Tumors that cause bleeding or pain

It’s also used to reduce blood loss before surgery, making tumor removal safer. Embolization can serve as a palliative tool, especially when traditional treatments aren't effective or possible.

Benefits of a minimally invasive approach

Embolization offers several advantages:

• Shorter recovery times
• Reduced risk of complications
• Minimal blood loss
• Preservation of surrounding healthy tissue
• Most procedures are completed on an outpatient basis

Because embolization is image-guided, it delivers targeted results with less impact on the rest of the body. 

Who is a candidate for tumor embolization

Tumor embolization is typically recommended for patients whose tumors are difficult to remove surgically or when surgery presents high risks due to age, underlying health conditions, or tumor location. It’s also used in combination with other treatments to improve outcomes or relieve symptoms.

Ideal candidates often include those with large or highly vascular tumors, tumors that bleed easily, or tumors that aren’t responding well to systemic therapies. In some cases, embolization is used preoperatively to reduce bleeding during surgery or to shrink a tumor beforehand.

Before recommending the procedure, the team at Third Coast Vascular evaluates medical history, imaging results, and overall treatment goals. This ensures the approach is safe, and appropriately aligned with each patient’s care plan.

What to expect after the procedure

After tumor embolization, patients may experience mild discomfort, fatigue, or low-grade fever. These symptoms are typical and, in most cases, resolve without issue within a few days. Our team provides detailed aftercare instructions, monitors healing, and coordinates with referring physicians or oncologists to ensure comprehensive support.

If you’re exploring treatment options for a tumor or need to manage related bleeding or pain, tumor embolization may be right for you. Contact Third Coast Vascular to schedule a consultation with our interventional team and learn more about this advanced treatment.
