Background:
Distal anterior cerebral aneurysm (DACA) represents 4% of intracranial aneurysms. Two treatment modalities are available: microsurgery and endovascular therapy (EVT).
Objective:
To compare the results between microsurgery and EVT in a modern French cohort.
Methods:
A multicenter retrospective cohort study of 3 French neurosurgical units was carried out from January 1, 2015, to December 31, 2020. All participants were adult patients who required treatment for a ruptured or unruptured DACA aneurysm.
Results:
A total of 69 patients were included; 16 patients (23.2%) were treated by microsurgery and 53 (76.8%) were treated by EVT. Thirty-one patients (44.9%) had ruptured aneurysms. The complication rate was low, with 1 death and 1 symptomatic ischemia. There was no difference in complications between microsurgery and EVT (P = 0.22). The number of retreatments was higher in EVT (15% vs. 0%) but not significantly (P = 0.18).
Conclusions:
In the specific subgroup of DACA, both treatment modalities are effective in ruptured and unruptured aneurysms, with a low rate of complications. Retreatment may be more frequent in EVT but it does not lead to more complications.
