[Cerebral hemodynamics and metabolism in the acute stage of cerebral aneurysm rupture].

The relationship between lipid peroxidation products and the severity of arterial spasm was studied in 86 patients. For this, the level of radical production, the content of the end lipid peroxidation product malonic dialdehyde and the overall antioxidative activity of lumbar cerebrospinal fluid were determined during 24-hour Doppler monitoring of blood flow in the middle cerebral and internal carotid arteries. Following subarachnoidal hemorrhage, the activation of lipid peroxidation processes was shown to correlate with the severity of arterial spasm and it is likely to contribute to the development of late ischemias.

[The prognosis of the ischemic complications due to a cerebral arterial spasm after subarachnoid hemorrhages (clinico-dopplerographic comparisons)].

The clinical status, angiographic and Doppler ultrasound transcranial findings were compared in 50 patients with acute subarachnoidal hemorrhage (40 with aneurysmal hemorrhage and 10 with unknown hemorrhage). There was a correlation between the change in the linear velocity of blood flow in the cerebral arteries and the clinical manifestations of arterial spasm-induced brain ischemia. With this, Doppler signs of arterial spasm appeared as clinical manifestations 3-4 days earlier.

[The dopplerographic diagnosis of arterial spasm in patients with subarachnoid hemorrhages].

The paper deals with the specific features of using Doppler transcranial sonography in patients with subarachnoid hemorrhage. It describes the advantages and disadvantages of the method for the diagnosis of arterial spasm of various intracranial arteries. A comparison of angiographic and Doppler sonographic findings revealed that the values of the peak systolic velocity of blood flow (r = -0.

[Clinico-neuropsychological observations of patients with aresorptive hydrocephalus].

Clinical and neuropsychological examinations were made in 33 patients with post-bleeding hydrocephalus. The neuropsychological syndrome in aresorptive hydrocephalus due to ruptures both of arterial aneurysms and of arteriovenous malformations was shown to appear as dysfunction of frontal and diencephalic regions of the brain. It included disorientation, inertness, spontaneity, perseveration, awakening fluctuations, persistent memory dysfunctions and sluggish mentality.

[Lipid peroxidation of the cerebrospinal fluid in patients with arterial cerebral aneurysms].

It was established from study of lipid peroxidation (LOP) products in 19 patients (16 with subarachnoid hemorrhages /SAH/ resulting from rupture of arterial aneurysms and 3 with arterial hemorrhages in the "cold" period) that their content was significantly higher in patients with a history of 2 or 3 SAH than in those who had suffered from a single SAH. The LOP level in the c.s.
