RESUMEN
AIM: The study is an integrated assessment of clinical, imagistic and morphological parameters in severe intracerebral hemorrhages (ICH) complicated with subarachnoid effusion (SAE). MATERIALS AND METHODS: The studied group had 37 cases of patients with ICH and SAE who were hospitalized in the Emergency County Hospital of Craiova and died during hospitalization. The parameters evaluated were clinical (relation with the seasons, age, sex, arterial blood pressure, the motor deficit, degree of coma and Glasgow score at admission) and morphological (the sites of the intraparenchymal hematoma and SAE, the size of the intraparenchymal hematoma, the presence of the mass effect, and the association of intraventricular effusion). The latter were assessed on CT films and during autopsy. RESULTS: The presence of SAE as a complication of ICH showed a predilection for cold seasons, especially winter. From the 37 studied cases, 18 were men and 19 women. 51.3% of the patients were in the fourth and fifth life decade. Almost 73% of the patients had third stage arterial hypertension at admission, over 56% motor deficits and almost 49% Glasgow scores lower than 6. The hematomas had huge dimensions as compared to hosting encephalic structures, in lobar sites involving more than one lobe. Other risk factors as mass effect, perilesional edema and intraventricular extension (IVE) were constantly present. CONCLUSIONS: The association of SAE with other independent risk factors such as hypertension, low Glasgow scores, dimensions of hemorrhagic foci, presence of mass effect, perilesional edema and intraventricular extension (IVE) results in the death of patient despite any sustained therapeutical intervention.

AIMS: The study is an integrated assessment of clinical, image and morphological parameters in severe intracerebral haemorrhages (ICH) complicated with intraventricular extension (IVE). MATERIAL AND METHODS: The studied group had 93 cases of patients with ICH and IVE who were hospitalized in the Emergency County Hospital of Craiova and died during hospitalization. The parameters evaluated were clinical (relation with the seasons, age, sex, arterial blood pressure, the motor deficit, degree of coma, Glasgow score at admission and medical care) and morphological (the sites of the intraparenchymal haematoma and IVE, the size of the intraparenchymal haematoma, the presence of the mass effect, perilesional oedema and subarachnoid effusion). The latter were assessed on CT films and during autopsy. RESULTS: The presence of IVE as a complication of ICH showed a predilection for cold seasons, especially autumn. From the 93 studied cases 51 were men and 42, women. 52.6% of the patients were in the fifth and sixth life decade. Almost 80% of the patients had IIIrd stage arterial hypertension at admission, over 80% motor deficits and almost 60% Glasgow scores lower than 6. The ventricular effusion involved at least one of the lateral ventricles. The hematomas had huge dimensions as compared to hosting encephalic structures, in lobar sites involving more than one lobe. Other risk factors as mass effect and perilesional oedema were constantly present. CONCLUSIONS: The association of IVE with other independent risk factors such as hypertension, low Glasgow scores volume of intraventricular bleeding, dimensions of haemorrhagic foci, presence of mass effect and perilesional oedema results in the death of patient despite any sustained therapeutic intervention.

AIMS: The study was performed in order to assess the alterations of extra-parenchymal and intraparenchymal vascular structures in 82 hypertensive patients suspected of primary intraparenchymal hematoma, which died and were autopsied in order to confirm the diagnosis. MATERIAL AND METHODS: The studied material consisted of nervous tissue situated near and distant from the haemorrhagic lesion. The specimens of nervous tissue were processed by the classical histological technique and stained with the usual stainings and with immunohistochemical stains for basement membranes and endothelial cells. RESULTS: Extra-parenchymal arteries showed classic lesions of atherosclerosis. Atheromatous lesions were of all types, even the extension towards the media being encountered a complication with thrombosis. At the level of the intraparenchymal blood vessels, the spectrum of the lesions due to arterial hypertension included all steps of vascular wall degeneration, from hypertrophy of smooth muscle layer to complete hyalinization of arterial wall, but with a focal irregular distribution, not related with the proximity of haemorrhagic focus. High arterial blood pressure also influenced the capillary walls which showed focal or circumferential thickening due to the densification of the type IV collagen material from the basement membrane structure. The CD34 immunostaining showed that endothelial cells kept their structural integrity. CONCLUSIONS: The sequence of degenerative lesions of the cerebral vascular wall culminates with the hyalinization of excessive fibrillar material form arteriolar wall or from basement membranes. Hyalin material is weakening the wall resistance to the stress determined by the high values of blood pressure in hypertension, and, correlated with a minimal resistance of the surrounding cerebral parenchyma, can explain why the cerebral parenchyma is the only tissue in which blood pressure variations can determinate vascular rupture and cerebral haemorrhage. The more adequate term for describing the vascular wall changes seems to be sclerosis (arteriolar and even capillary) with hyalinosis.
