Abstract

We assessed the morphological changes induced by intraventricular haemorrhage (IVH) and investigated the effects of intraventricular fibrinolytic treatment following IVH. The experiment was performed in 30 Wistar rats. In first (control) group (15 rats) animals received intraventricular injection of 40 microl autologous blood with 10 microl normal saline. In second group (15 rats) 40 microl autologous blood with 10 microl t-PA recombinant tissue plasminogen activator (t-PA) was injected in ventricular of the animals. Morphological examination of the brains were carried out 2 days and 21 days following IVH. Marked losses of the ependymal covering of the ventricular walls, choroids plexus were founded in bouth groups. The results indicate that intraventricular administered t-PA significantly enhanced the lysis of intraventricular blood clots, but r-PA (in second group) promoted delayed periventricular white matter edema formation (more 21 days).
