SUMMARY

Background: Anterior communicating artery aneurysms (Acom) accounts for 23 - 40% of ruptured intracranial aneurysms. A ruptured cerebral aneurysm is a medical and neurological emergency that requires early diagnosis and prompt management to reduce mortality and sequelae.

Material and method: Retrospective description of 40 patients who were diagnosed of ruptured anterior communicating aneurysms based on the clinical characteristics, imaging and results of endovascular treatment. Clinical outcomes were evaluated on a modified Rankin scale.

Results: Patients suffering from ruptured Acom aneurysms presented headache (100%), thunderclap headache (45.0%), vomiting with or without nausea (60%), nuchal rigidity (67.5%). Aneurysms’s size was under 5mm, 5-15mm and over 15mm accounting for 52.4%, 45.0% and 2.5% respectively; None of the patients had giant aneurysms. Dome and neck ratio of <1.2 ; 1.2 - 1.5 and ≥1.5 account for 37.5%; 32.5% and 30.0% respectively. Diameter of Acom ruptured aneurysm’s neck under and above 4mm accounted for 80.0% and 20.0%, respectively. Successful coiling embolization of Acom ruptured aneurysms without complications achieved in 80.0%. The patient had a good clinical recovery of 92,5% after 3 to 6 months follow-up.

Conclusion: Coiling embolization of Acom ruptured aneurysms were effective and safe.
