    Notizen: Abstract The frequency, predisposing factors and clinical consequences of haemorrhagic infarcts and damaged blood-brain barrier as shown by contrast enhancement (CE) in ischaemic cerebral infarcts are controversial. We prospectively compared the sensitivity of CT and MRI to haemorrhagic transformation (HT) and CE. We also wished to investigate the clinical significance of HT and factors possibly associated with it. We studied 36 patients with acute ischaemic infarcts in the middle cerebral artery territory during the first 2 weeks after the ictus. After CT and rating of the neurological deficit on admission, serial examinations with clinical neuromonitoring, contrast-enhanced CT and MRI were done on the same day. The occurrence and severity of HT were correlated with CE, stroke mechanism, infarct size, development of neurological deficits and antithrombotic treatment. The frequency of HT detected by MRI was 80 %. CE usually preceded HT or was seen simultaneously. MRI had a higher sensitivity than CT to HT and CE. Severity of HT was positively correlated with infarct size (P 〈 0.01). HT had no influence on patient's neurological status. Neither the type of antithrombotic treatment nor the stroke mechanism was associated with the severity of HT. No parenchymal haemorrhage occurred.

    Beschreibung / Inhaltsverzeichnis: Summary DAVF are difficult to recognize with CT- or MR-imaging. Diagnosis is often possible by arterial MRA. The type of the venous drainage as demonstrated by DSA is relevant for the clinical decision. Most often the endovascular occlusion of the affected venous segment a suitable therpeutical approach.
    Notizen: Zusammenfassung Kraniale arteriovenöse Durafisteln (DAVF) sind in der Schnittbilddiagnostik schwierig, am besten mittels der arteriellen MRA erkennbar. Klinisch ist die Einteilung nach dem in der DSA ermittelten venösen Drainagetyp relevant. Therapeutisch kommt in erster Linie der transvenöse endovasculäre Verschluss in Betracht.
