[Cerebral angiospasm in subarachnoid hemorrhages].

Publications on the prevalence and causes of subarachnoid hemorrhages (SAH) and one of the most frequent their complications, cerebral vasospasm (CV), are reviewed. The issues of the pathogenesis and pathophysiology of CV in SAH are covered, basic methods of its clinical and paraclinical verification are described. The authors reviewed the reasons of the discrepancy between clinically significant and angiographic vasoconstrictive reactions.

[Ocular and orbital blood flow in apparently healthy adults].

Doppler measurements of ocular and orbital blood flow at rest were studied using duplex ultrasonography in 30 apparently healthy adult volunteers. The following linear and calculated Doppler measurements were estimated at rest: blood flow in ophthalmic artery (OA), central retinal artery (CRA), posterior ciliary arteries, central retinal vein and superior ophthalmic vein (SOV). In 10 patients Doppler measurements of blood flow in OA, CRA SOV were estimated 5 times by 2 observers with different level of skills in ultrasonographic ophthalmologic examination.
