Summary
Distal anterior cerebral artery aneurysms are rare but require specialized surgical management due to their tendency for multiplicity and bleeding. Microsurgical techniques achieved excellent outcomes with no deaths in this patient cohort.
Area of Science:
- Neurosurgery
- Vascular neurology
- Cerebrovascular disease
Context:
- Distal anterior cerebral artery aneurysms are uncommon, accounting for 0.35-4.5% of intracranial aneurysms.
- These aneurysms present unique challenges due to their location and potential for multiplicity.
Purpose:
- To review the surgical management and outcomes of patients with distal anterior cerebral artery aneurysms.
- To highlight the specific characteristics and treatment strategies for these rare aneurysms.
Summary:
- Twenty patients with distal anterior cerebral artery aneurysms underwent microsurgical treatment between 1981 and 2002.
- The genu of the corpus callosum was the most frequent location (65%). 80% of patients achieved complete recovery with no mortality.
- Key characteristics include high multiplicity and early bleeding tendency; midline location allows for small craniotomies, and avoidance of cerebral retractors minimizes morbidity.
Impact:
- Demonstrates the efficacy of specialized microsurgical techniques for treating distal anterior cerebral artery aneurysms.
- Provides insights into the management of these rare cerebrovascular lesions, emphasizing patient outcomes and surgical considerations.
