Percutaneous embolization for cervicofacial neoplasms and hemorrhages

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Oncology

Background:

• Head and neck neoplasms and vascular malformations present complex management challenges.
• Hypervascular lesions and associated bleeding require effective therapeutic strategies.

Purpose of the Study:

• To evaluate the efficacy of percutaneous embolization for head and neck hypervascular neoplasms, vascular malformations, and bleeding.
• To assess its role in curative, preoperative, and palliative settings.

Main Methods:

• Retrospective analysis of 85 patients over 8 years.
• Inclusion of patients undergoing embolization for tumors, vascular lesions, refractory bleeding, or epistaxis.
• Success defined by reduced intraoperative blood loss (<500 ml) and/or complete vessel occlusion on angiography.

Main Results:

• Complete preoperative embolization achieved in 83.5% of patients; partial in 10.5%.
• Successful outcomes reported for all cases of refractory tumor bleeding and epistaxis.
• Significant reduction in intraoperative bleeding and improved tumor resectability.

Conclusions:

• Preoperative percutaneous embolization enhances surgical outcomes for head and neck vascular lesions and tumors.
• Endovascular embolization provides an effective treatment for cervicofacial bleeding, including that from tumors, malformations, and epistaxis.
