Embolization of Musculoskeletal Bone Tumors

Bone tumors may present as incidental findings, with pain or loss of function, or as fractures. There is a broad range of indications for transarterial embolization (TAE) in primary or metastatic bone tumors: to reduce operative hemorrhagic risks, to simplify or allow more definitive surgery, or in the context of pain palliation, fever, bleeding, or hypercalcemic and other rheological factors. Embolization may also increase tumor sensitivity to chemotherapy or radiation therapy. The procedure itself is often complex with significant risk to adjacent structures and is usually part of a wider treatment strategy. There are many options of embolic agent, techniques, and end points but all aim to devascularize the tumor. Catheter angiography at the time of TAE is used to determine the correct embolic agent and technique with care taken to isolate at risk structures. Many factors determine the best choice of embolic material, probably the most important of which is operator experience. In life-threatening situations or in preoperative embolizations of metastatic tumors, many operators opt for a combination of particulate emboli and stainless steel or platinum coils. Agents discussed include polyvinyl alcohol particles, trisacryl microspheres, gelatin sponge, liquid embolic agents, and embolization coils. Tumor types treated include vascular metastatic lesions, commonly renal cell or thyroid, particularly in locations prone to fracture; giant cell tumors; aneurysmal bone cysts; vertebral hemangiomas, osteosarcomas; arteriovenous malformations; and osteoblastomas. TAE should be considered in the treatment algorithm of primary or secondary bone tumors. Specific benefit is present where there is a high risk of bleeding at surgery, where there is spinal involvement and neural encroachment, where active bleeding is present or in awkward surgical locations where prolonged surgery is anticipated. KEYWORDS: Embolization, bone tumors, metastasesObjectives: Upon completion of this article, the reader should be able to identify which primary or metastatic bone tumors are amenable to embolization and which factors and locations influence the procedural technique and associated risks. The reader should also be able to identify procedures and techniques to increase efficacy and reduce risk as well as be able to choose the correct embolic material.

Preoperative and Therapeutic Embolization of Extremities of Bone and Soft Tissue Tumors

et al. 2012

Embolization of bone and soft tissue tumors has a broad range of indications, from curative treatment to palliation. The main purpose of embolization is to occlude as much of the tumor blood supply as possible. The outcome ranges from complete tumor devascularization and necrosis to degrees of ischemia and hypovascularity. Thus, the tumor will shrink, bleeding will be reduced, borders between the tumor and surrounding tissue will become clear, and resection will be easier. The purpose of this study was to correlate the effectiveness of preoperative embolization with the blood loss and transfusion requirement during surgery for bone or soft tissue tumors.

Однак на сучасному етапі розвитку методики трансартеріальної емболізації (ТАЕ) показання до застосування даного методу розширилися і застосовуються у лікуванні як злоякісних пухлин (первинних і вторинних) кістково-м'язової системи, так і навіть доброякісних новоутворень [15].…”

Summary. The article considers current issues of modern medicine, in particular the use of the method of transarterial embolization of blood vessels in the treatment of malignant tumors of the extremities. The purpose, indications, technical features and materials used for its implementation, as well as contraindications and complications are highlighted. Its efficiency in preparation of the patient for a surgery of musculoskeletal malignant tumor is considered. Analysis of the modern domestic and foreign literature shows that now indications for use of this method expand, and technical possibilities of the equipment and physical and chemical properties of materials improve. The issues of further study and development of the problem are outlined.
