The risk factors and formation time of de novo aneurysms are not fully known. Congenital, environmental and hemodynamic factors can play a role in aneurysm development. The 43-year-old female patient was operated with the middle cerebral artery superior trunk aneurysm in our clinic. She came to us again after 17 months with a severe headache. In computed cranial tomography angiography, the middle cerebral artery superior trunk placement aneurysm was found to have a partial clip and de novo aneurysm was developed. She was re-operated for de novo aneurysm. In this study, the risk factors in development of de novo aneurysms were discussed in the light of literature through this patient.en10.4103/bc.bc_2_20info:eu-repo/semantics/openAccessDe novo aneurysmmicrosurgeryrisk factorsAngiographic Follow-UpIntracranial AneurysmsSubarachnoid HemorrhageCerebral AneurysmsEnlargementFrequencyDiagnosisAssessment of risk factors in de novo aneurysm developmentArticle6320821033210047WOS:000581617500012N/A
