[The risk of complications of cerebral angiography in patients with cerebral aneurysms in relation to the time of its use].

The authors analysed the effect of cerebral angiography on the condition of the patients after haemorrhage from an intracranial aneurysm. The studied material comprised 242 patients in whom cerebral angiography was carried out at various times after the haemorrhage by the method of direct percutaneous needle insertion into the carotid artery. Complications of angiography included: worsening of the general condition or neurological condition during the angiography and within 24 hours after it. Such complications were found in 14 patients (5.8%). In only 3 cases they appeared during the angiography. No cases of repeated haemorrhage from the aneurysm were observed. The greatest risk of complications was after 7-9 days from the haemorrhage which was connected with the greatest intensity of arteriospasm at that time. All carotid angiographies were done using a contrast medium hypersmolar and hypertonic in relation to the blood and cerebrospinal fluid (Uropolinum-Polfa 60%).
