[Dopplerographic assessment of the autoregulation of the blood supply to the brain in neurosurgical pathology].
The development of an informative, noninvasive technique for evaluating the reserve of the cerebral circulatory system is a topical task of clinical angioneurology. The authors developed methods of Doppler evaluation of an autoregulatory response from hyperemic changes after short-term regional hypotension caused by digital compression of the cervical carotid. They calculated the indices acceptable in routine clinical practice, defined the range of their values in health and in typical variants of cerebral circulatory insufficiency in patients with disseminated neurosurgical pathology. The carotid compression test by recording linear blood flow velocity in the cerebral arteries is a safe, valid, and reproducible method of semiquantitative assessment of the autoregulation reserve which may be used to determine the tension of resistive vessels in the middle cerebral arterial bed as an important index of the functional status of the cerebral circulatory system.
