We assessed new proposed risk factors (i.a. number of outflows and outflow diameter) of intracerebral haemorrhage due to intracranial dural arteriovenous fistula and presented our personal experience in endovascular treatment of dural arteriovenous fistulas.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>The patient database from January 2006 and December 2016 was reviewed, and 25 patients with 28 dural arteriovenous fistulas were identified.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>50% of patients presented with intracerebral haemorrhage. Multiple dural fistulas occurred in 12% of patients. Spearman\u2019s rank correlation coefficient revealed that there was a\u00a0strong association between Cognard classification type and time needed to treat (r = 0.59, p &lt; 0.05), as well as the volume of contrast used (r = 0.77, p &lt; 0.05). Infratentorial (r = 0.53, p &lt; 0.05) and right-sided (r = 0.66, p &lt; 0.05) localisation were more challenging to treat. Bleeding was associated with poorer clinical outcome (r = 0.48, p &lt; 0.05). No significant differences were found between the non-haemorrhagic group and the haemorrhagic group regarding the number of outflows (p = 0.459) and largest outflow diameter (p = 0.298). Clinical evaluation at follow-up was as follows: 56% of patients were asymptomatic, 24% had non-significant disability, maintaining independency, 16% had moderate disability, and 8% died \u2013 one in the course of intracerebral haemorrhage and one due to other sustained injuries. There were no reported embolisation- related complications.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>To conclude, regardless of presentation, both symptomatic and asymptomatic dural arteriovenous fistulas deserve clinical attention, structured evaluation, and follow-up. Type I\u00a0fistulas were associated with haemorrhage in 1\/3 of all cases. Overall our results indicate that the risk of haemorrhage and dire consequences is multifactorial.<\/jats:p><\/jats:sec>","DOI":"10.5114\/pjr.2019.84602","type":"journal-article","created":{"date-parts":[[2019,5,15]],"date-time":"2019-05-15T11:33:17Z","timestamp":1557919997000},"page":"179-184","source":"Crossref","is-referenced-by-count":3,"title":["Are type I\u00a0dural arteriovenous fistulas safe?
