Therapeutic embolization of aneurysmal bone cyst

Area of Science:

• Interventional Radiology
• Orthopedic Surgery
• Vascular Surgery

Background:

• Aneurysmal bone cysts (ABCs) are benign, expansile bone lesions often causing pain and pathological fractures.
• Traditional treatments for ABCs can be invasive and may lead to significant morbidity.
• Minimally invasive therapeutic embolization offers a potential alternative for managing ABCs.

Purpose of the Study:

• To evaluate the efficacy and safety of transcatheter arterial embolization for treating aneurysmal bone cysts.
• To assess clinical outcomes, including pain relief and cyst size reduction.
• To observe radiological changes and complications following embolization.

Main Methods:

• Transcatheter arterial embolization was performed in five patients diagnosed with aneurysmal bone cysts.
• Embolization agents used included Ivalon particles, Gelfoam particles, and Gianturco coils.
• Patient outcomes were monitored for pain, cyst size, and radiographic evidence of healing.

Main Results:

• All five patients experienced complete pain relief post-embolization.
• A significant decrease in the size of the aneurysmal bone cysts was observed in all patients.
• Radiological follow-up exceeding 12 months revealed bone sclerosis and recalcification, indicating healing.
• No complications were reported during or after the embolization procedures.

Conclusions:

• Transcatheter arterial embolization is a safe and effective treatment for aneurysmal bone cysts.
• The procedure provides rapid pain relief and leads to cyst size reduction.
• Embolization promotes bone healing and offers a low-complication alternative to conventional therapies.
