[Intracranial angiomatous malformations]

Area of Science:

• Neurosurgery
• Neurology
• Vascular Malformations

Background:

• Intracranial arteriovenous malformations (AVMs) and cavernous angiomas pose significant risks, including hemorrhage and neurological deficits.
• Surgical intervention is a primary treatment modality for these vascular lesions.

Purpose of the Study:

• To evaluate the outcomes of surgical management for intracranial arteriovenous malformations and cavernous angiomas.
• To assess the efficacy of radical surgery in improving quality of life and preventing rebleeding.

Main Methods:

• A retrospective review of 21 patients with intracranial AVMs and six with cavernous angiomas operated over a four-year period.
• Analysis of surgical outcomes, including operative mortality, post-operative complications such as perfusion pressure breakthrough, and long-term quality of life.

Main Results:

• A total of 27 patients underwent surgery, with 16 presenting with ruptured lesions.
• One operative death occurred. Five patients experienced post-operative normal perfusion pressure breakthrough, with one resulting in a disabling deficit.
• Radical surgery was performed in 21 cases, leading to good quality of life in most ruptured cases and eliminating bleeding risk in unruptured cases.

Conclusions:

• Radical surgical resection is an effective treatment for intracranial arteriovenous malformations and cavernous angiomas.
• Surgery can significantly improve quality of life for patients with ruptured lesions and mitigate risks for unruptured lesions.
• Careful surgical planning and management are crucial to minimize post-operative complications like perfusion pressure breakthrough.
