Background: Ruptured tiny intracranial aneurysm (RTIA) is particularly rare seen. Treatment of RTIA is more difficult and not under control.Methods: We hereby present twelve rare cases of RTIA that were diagnosed based on DSA. These patients were found due to spontaneous or traumatic SAH, 11 of whom were treated only by electrocoagulation, and one of whom was treated by stent-assisted coiling and electrocoagulation.Results: There were eight patients with aneurysms located in posterior

The twelfth patient was carried out stent-assisted coiling and electrocoagulation. The twelve patients' average follow-up time was 12.5 months and the outcomes were all surprisingly excellent. No revascularization of aneurysm was found. Conclusions: Electrocoagulation with guidewire manipulation is a suitable method to treat RTIA. While large-scale studies with long-term follow-up are required to validate these promising results.
