The Importance of Preoperative Endovascular Embolization in Assisting Giant Musculoskeletal Tumor Surgery: A Case Series of A Tertiary Center in Indonesia

<ns3:p>Introduction The excision of musculoskeletal tumors often results in significant blood loss as its unique challenge. Increased vascularization is one of the main reasons for this challenge. Preoperative endovascular embolization may be a potential adjunct intervention to address this challenge. Case Presentation This is a case series of three patients with musculoskeletal tumors undergoing preoperative endovascular angioembolization. These patients underwent preoperative endovascular embolization a day prior to the surgery, all of which showed a significant reduction in vascularization and, subsequently, intraoperative bleeding. Tumors resected from the patients included a Giant Cell Tumor/Aneurysmal Bone Cyst of the right humerus, right femur liposarcoma, and gluteal and femoral liposarcoma. Conclusions This case report highlights the potential of preoperative embolization as a valuable adjunct to musculoskeletal tumor surgery, facilitating safer resection with reduced blood loss.</ns3:p>
