Background: Arteriovenous Malformations are one of the most common cerebrovascular diseases that can affect various parts of the brain. AVMs cause complications such as cerebral hemorrhage, epilepsy, and neurological lesions that can be prevented by different therapeutic procedures such as microsurgery, endovascular intervention, radiosurgery with gamma-knife, and non-surgical treatment. The current study aimed to evaluate the demographic features and clinical outcomes of patients with AVM who referred to Loghman Hakim Hospital.

Materials and Methods: A descriptive study was performed using medical records of patients with AVM who had referred to our center betwen 2011-2018. The demographic data and treatment outcome and complications were collected and interviews with patients were conducted. Data were analyzed using SPSS, version 18.

Results: Out of 47 cases, 70.2% were men and 29.8% women. A total of 25 patients were treated via microsurgery, while 14 patients received radiosurgery therapy, and 8 patients received non-surgical treatment. Treatment complications were observed in 40% of the patients who had surgically been treated (10 patients), the most common complication in patients with transient motor disorder.
 
Conclusion: Appropriate treatment approaches can improve initial symptoms of patients. However, decisions must be made to select the best treatment option based on the clinical conditions of the patients as well as the assessment of the possible effects of the complications to improve their quality of life.
