Complications of operations in neurosurgery

Complications of operations are negative, but inevitable companions of surgery and determine dissatisfaction with the outcome of treatment for both the doctor and the patient. In this regard, the improvement of the results of surgical treatment is associated not only with the improvement of the technique and skill of the surgeon, but also with the prevention and control of complications. On this path, it is necessary to analyze complications from your own practice and share negative experiences in scientific publications, at conferences, in the educational process. Despite the significance of the problem, there is still no single approved definition of “complication of surgery” in the surgical literature, and experts’ opinions on this matter differ. It is quite difficult to analyze scientific publications on this topic when different indicators of the frequency and structure of complications can be determined by different understanding of the term “complication” by specialists. This review presents the main approaches to the definition of “complication of surgery”, as well as other definitions proposed by some authors (“consequence of surgery”, “undesirable perioperative events”). Based on the conducted review, a variant of the use of terms is proposed.
