Summary

Surgical excision of large cerebral arteriovenous malformations (AVMs) without embolization is feasible. This approach allows for safe treatment of AVMs at more neurosurgical centers.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Vascular Neurology

Background:

  • Management of large cerebral arteriovenous malformations (AVMs) presents significant challenges.
  • Current strategies often involve pre-operative embolization, limiting treatment to specialized centers.
  • Developing alternative, widely accessible treatment options is crucial.

Purpose of the Study:

  • To evaluate the safety and efficacy of surgical excision of large cerebral AVMs without pre-operative embolization.
  • To determine if direct surgical removal can be a viable primary treatment modality.

Main Methods:

  • A retrospective study of 27 patients with large cerebral AVMs (>5 cm) diagnosed between 1986 and 1992.
  • Analysis of case records for patients treated surgically without embolization.

Main Results:

  • Eleven out of thirteen patients who underwent surgery achieved total AVM excision.
  • No pre- or intra-operative embolization was performed in the surgical group.
  • All surgically treated patients experienced no post-operative neurological deterioration.

Conclusions:

  • Direct surgical excision of large cerebral AVMs, without prior embolization, is a safe and effective treatment.
  • This approach offers acceptable outcomes and expands treatment accessibility for AVM patients.
