Preoperative tumor embolization
Summary
Tumor embolization effectively reduced tumor stain in 12 cases, including meningiomas and angiofibromas. Treatment selection depended on tumor type, feeding artery, and histology for optimal preoperative embolization.
Area of Science:
- Interventional Radiology
- Neurosurgery
- Oncology
Background:
- Preoperative embolization is crucial for specific tumor types, including deep-seated and hypervascular tumors.
- Tumor embolization aims to reduce vascularity and facilitate surgical resection.
Purpose of the Study:
- To evaluate the efficacy of preoperative embolization for various tumor types.
- To determine optimal embolic agents and techniques based on tumor characteristics.
Main Methods:
- Performed embolization on 12 patients with tumors requiring preoperative treatment between September 1996 and September 1998.
- Utilized estrogen-alcohol and polyvinyl acetate for most cases; polyvinyl alcohol particles and liquid coils for specific scenarios.
- Employed direct tumor puncture with a N-butylcyanoacrylate mixture for a hypervascular juvenile angiofibroma.
Main Results:
- Angiography confirmed a reduction in tumor stain in all treated cases.
- Successful embolization was achieved for meningiomas, hemangiopericytoma, angiofibroma, and glomus tumors.
- Individualized embolic strategies were employed based on clinical and pathological factors.
Conclusions:
- Preoperative embolization is a valuable technique for managing selected tumors.
- The choice of embolic material and technique should be tailored to the specific tumor and clinical context.
- Embolization contributes to reduced tumor vascularity, aiding subsequent treatment.
