Introduction: Rupture of intracranial aneurisms leads to severe
morbidity and mortality. There are two modalities of treatment surgery and
endovascular treatment. The diagnosis is made by angiography (DSA, CTA, RMA).
The angiographic features used to assess the risk of the complications and
choose the treatment modality are size, location and aneurism morphology. Materials
and Methods: We reviewed and analyzed the computed tomographic angiography
and magnetic resonance angiography of all patients admitted to the hospital of
Mali with IAs from 2015 to 2021 either 7 years. Patients who were less than 18
years old, those with non-aneurysmal SAH, patients who request a discharge and
those with an incomplete angiographic description of the IAs were excluded from
the analysis. Results: We have collected 105 patients with 109
aneurysms. The sex ratio was 2/1 in favor of females. The mean age was 44.51
years with the range from 18 to 70 years. The presentation mode was
subarachnoid hemorrhage (SAH) in 97% of cases. 76.19% had confirmed high blood
pressure before the bleeding. 19.04% were diabetics. 98% of our patients have
made a CT angiography and 2% have made MR angiography for the aneurysm
diagnosis. 97.24% of aneurisms were located in the anterior part of the Willis
circle. 39.44% of these aneurisms were the anterior communicating complex
aneurysm. 27.52% of aneurysm had a small size, 42.20% had a medium size, 20.18%
large size against 5.50% of the giant (Figure 3) and the middle cerebral artery
was the most involved in the least. 95.41% of cases were saccular aneurysms
against 4.59% fusiform. Conclusion: The angiographic feature of an
intracranial aneurism in the Malian population may differ from other populations
of the sub-region. The anterior communicating complex aneurysm is more common
and the aneurism of the posterior part of the Willis circle is less common. We
found the aneurism size ≥ 6 mm, ACA, MCA and Pcom more frequent.
