Summary

Presurgical embolization is effective for difficult-to-operate, highly vascularized tumors, especially in head and neck regions. This interventional radiology technique offers better outcomes for certain angiomatous lesions compared to surgery alone.

Area of Science:

  • Interventional Radiology
  • Vascular Surgery
  • Oncology

Background:

  • Highly vascularized tumors in head and neck regions pose significant surgical challenges.
  • Conventional surgery may be difficult or impossible for certain complex lesions.
  • Angiomatous lesions can present unique treatment difficulties.

Purpose of the Study:

  • To demonstrate the utility of presurgical embolization for challenging tumors.
  • To compare embolization outcomes with surgical interventions for specific lesions.
  • To highlight prerequisites for safe and effective intravascular embolization in head and neck procedures.

Main Methods:

  • Utilized digital subtraction angiography (DSA) for optimal intravascular embolization technique.
  • Employed computed tomography (CT) scans (axial and coronal) for lesion and bone destruction assessment.
  • Prioritized maxillary artery embolization, followed by facial artery injection (per Davis) to confirm collateral opacification and completeness of embolization.

Main Results:

  • Presurgical embolization proved useful for highly vascularized tumors where surgery is difficult or impossible.
  • Embolization achieved superior results compared to surgery in select cases of angiomatous lesions.
  • Devascularizing juvenile nasopharyngeal angiofibroma yielded best results when the maxillary artery was embolized first.

Conclusions:

  • Presurgical embolization is a valuable tool for managing complex, highly vascularized head and neck tumors.
  • Optimal technique, experienced team, and patient cooperation are crucial for successful interventional procedures.
  • Maxillary artery embolization, confirmed by facial artery injection, is an effective strategy for juvenile nasopharyngeal angiofibroma.
