[Repeated closed craniocerebral trauma]. / Povtornaia zakrytaia cherepno-mozgovaia trama.

As many as 446 patients with repeated craniocerebral injury and 386 patients with primary injury, analogous in respect of severity, were subjected to clinical and physiological examinations. On comparison of the results of examining the above two patients' groups it has been revealed that repeated brain injury may be characterized by its own features and runs a graver course as compared to primary injury. This manifests by more pronounced and persistent general cerebral and focal symptoms, disorders of the dynamics of the CSF toward hypotension, vegetative disorders in the form of lability and asymmetry of arterial pressure, thermal asymmetry, prolongation of the time of the thermoregulation vascular reflex and resolution of the blister according to the McClure-Aldrich test, and so forth. According to the therapeutic indications, 204 patients with repeated injury underwent pneumoencephalography. Manifest alterations in CSF-containing spaces, the intensity of which depended on the number of injuries, were revealed in 90.2% of them early after the injury. A special complex of pathogenetic therapy provided to 212 patients with repeated injury allowed attaining more favourable results as compared to 234 analogous patients who received routine treatment.

[Validation of the use of the CO2 laser in operations on the brain]. / Obosnovanie primeneniia CO2-lazera rpi operatsiiakh na golovnom mozge.

It is reported that the CO2-laser can be used in operations on the brain. Information is given on the response of the brain structures to irradiation with a wave length of 10.6 microns. The optimal regimens of the device operation were elaborated depending on the concrete object of the various stages of the surgical intervention. The medical laser device Skal'pel'-1 was used in the clinic in 109 operations. The low traumatization of such operations and the favourable course of the postoperative period are pointed out.

[Clinical and roentgenological diagnosis of spinal cord compression in acute closed trauma of the cervical spine]. / Kliniko-rentgenologicheskaia diagnostika sdavleniia spinnogo mozga pri ostroi zakrytoi travme sheinogo otdela pozvonochnika.

The clinical picture of injury to the spinal cord in the acute period of the trauma and the results of radiological examination of 184 patients with closed trauma of the cervical spine are analysed. Associations of clinical and radiological signs were revealed which pointed to compression of the spinal cord and showed the degree of its damage. The data obtained allow the method of treatment to be chosen and the possible outcome of the spinal cord injury to be prognosticated.

[Late results of cranioplasty using explants in children]. / Otdalennye rezul'taty kranioplastiki éksplantatami u detei.

The work is based on the analysis of 101 clinical cases in 91 of which children were subjected to cranioplasty in different periods after operation for craniocerebral injury, which terminated in the formation of a bone defect. In 5 children cranioplasty was conducted because the bone in the area of the linear fracture had resorbed, and in another 5 children it was carried out as a final stage of operation for anterior craniocerebral herniations. The children's age ranged from 3 months to 16 years. The late results of treatment were studied in 79 of 101 patients in follow-up periods of 12 months to 25 years, in 31 of them in periods of 10 to 25 years after cranioplasty. Cranioplasty must be undertaken in children as early as possible. Primary and early cranioplasty are conductive to the prevention of the formation of a meningocerebral cicatrix and a coarse adhesive process in the meninges and brain matter and are more effective than late cranioplasty.

[Cranioplasty using radiopaque allotransplants]. / Kranioplastika s primeneniem rentgenokontrastnykh allotransplantatov.

A method for contrasting plates of acrylic resins for cranioplasty in defects in the skull bones was developed. Per each 1.0 g of protacryl (or butacryl, etc.) powder 0.2 g of iodine-containing agents (verografin, urografin, urotrast, etc.) was added. This ensured a high contrast of the allograft not only in the immediate but also in the late period. The developed method is of great significance in conducting expert medical assessment of working capacity when there is no corresponding medical documentation and the medical history is unclear.

[Surgical tactics in injuries of the cervical portion of the spine and spinal cord]. / Khirurgicheskaia taktika pri travme sheinogo otdela pozvonochnika i spinnogo mozga.

From experience of many years, the author developed a method for the treatment of patients suffering from closed injury to the cervical spine and spinal cord. The method includes the correction of deformities of the spine and spinal canal and all types of compression of the spinal cord through an anterior or posterior approach, each having its definite indications. As a result of the application of the method in 208 patients lethality was reduced to 10.6% and the conducting function of the damaged spinal cord was improved, in some cases considerably, in 59.6% of the patients.
