Background: In the case of sudden or violent death, occurring in the rehabilitation period after a previously performed coronary bypass surgery, a forensic medical examination is usually prescribed. In recent years, the number of such forensic examinations has increased. At the same time, problems were revealed related to the lack of guidelines for the study of coronary shunts and recommendations on the structure of forensic diagnosis. Aims: This study aimed to summarize significant differences and features of coronary shunt research methods and give examples of diagnosis in cases of forensic examinations of corpses of patients who underwent coronary bypass surgery. Conclusions (acts) of forensic medical examinations (studies) of corpses performed at the bureau of forensic medical examination of the city of Moscow for the five-year period in 20122016 were studied. Cases of forensic examinations in patients who had previously undergone coronary bypass surgery were identified, original technical methods for sectional study of postoperative shunts are summarized, and options for constructing and substantiating sectional diagnoses were developed. In the analysis of 135, 446 conclusions (acts), 56 cases of forensic examinations of corpses of persons with signs of previously performed coronary bypass surgery were selected. Distinctive features of original methods for the study of shunts, tasks resolved during the study of native and prosthetic heart vessels, and examples of the design of forensic protocols are described. Examples of construction and substantiation of forensic diagnoses are also provided. Conclusion: This study revealed original technical methods for the study of coronary shunts during the concealment of corpses and examples of protocols of identified changes, and options for the formulation of forensic medical diagnoses in cases of forensic examinations of corpses of persons with a previously performed coronary bypass surgery are given.

Background: Acute mechanical intestinal obstruction is relevant for surgical and forensic practice. However, in forensic literary sources, the structure of death from intestinal obstruction is not sufficiently covered. Aims: Investigate the structure of mortality due to acute mechanical obstruction of the intestine according to the conclusion of forensic medical examinations for the period 20152019, generalize and highlight the peculiarities of sectional practice in this pathology compared to clinical data. Results: The number of deaths from mechanical intestinal obstruction during the studied period of forensic practice was stable. The most common cases were deaths from acute mechanical intestinal obstruction caused by the impairment of various external ventral hernias or prior to the adhesion process in the abdominal cavity. Conclusions: The structure of mortality from acute mechanical intestinal obstruction according to forensic expert practice differs from clinical data, where the adhesion form of mechanical obstruction prevails significantly.
