Unfortunately, mistakes in surgical practice are far from uncommon. Many papers have been published on this subject in special journals and the general non-medical press. A large number of clinical and anatomical conferences very often discuss errors in surgical practice, but rarely give specific recommendations for their prevention, especially with regard to organizational measures. Diagnostic errors are quite common, which often entail treatment-tactical errors. It should be emphasized here that most of the errors are noted with common diseases (IV Davydovsky). An underreporting of anamnesis can lead to an irreparable mistake.

Syringomyelia affects people predominantly between the ages of 20 and 50. Deep trophic disorders of bones, joints, muscles and skin often lead patients with syringomyelia to a surgeon, while the primary lesion is the spinal cord. The most common surgical complications of syringomyelia are burns associated with loss or decrease in temperature sensitivity, kyphoscoliotic deformities of the spine in the cervical and thoracic regions with the formation of a rib hump, arthropathic deformities of the joints with arbitrary dislocations, massive effusions, peculiar deformities of the hand with an increase in its size (cheiromegaly), edema of soft tissues, long-term non-healing painless panaritiums, sometimes the loss of whole phalanges (mutations).

Thrombosis and embolism, according to statistics cited by many authors, are one of the important causes of mortality in the world's population (6, 8, 28).

In a previous report (1961), the results of our observations on the change in the so-called procoagulant blood factors in patients with coronary insufficiency under the influence of anticoagulant therapy were summed up.

Epilepsy is one of the most common neuropsychiatric diseases, which, due to its long course, difficulties in treatment and severe consequences, has not only medical but also great social significance.
