Spinal Cavernous Malformations: A Narrative Review

Area of Science:

• Neurology
• Neurosurgery
• Vascular Malformations

Background:

• Spinal cord cavernous malformations (SCCMs) present complex management challenges.
• Treatment decisions hinge on neurological status, lesion features, and intervention timing.

Purpose of the Study:

• To evaluate the efficacy of surgical versus conservative management for SCCMs.
• To identify factors influencing outcomes in SCCM treatment.

Main Methods:

• Review of studies comparing surgical resection and conservative management of SCCMs.
• Analysis of patient neurological status, lesion characteristics, and timing of intervention.

Main Results:

• Surgical resection is indicated for symptomatic SCCMs, particularly large or progressive lesions, aiming for gross total excision.
• Conservative management is suitable for small, asymptomatic SCCMs with regular monitoring.
• Early surgery (within 3 months) is associated with better long-term outcomes and neurological recovery.

Conclusions:

• Optimal SCCM management requires careful consideration of individual patient factors and lesion characteristics.
• Early surgical intervention may improve neurological recovery and prevent hemorrhage in symptomatic SCCMs.
• Further research is needed on the optimal timing for surgical intervention in SCCMs.
