RESUMEN
GOAL: Presentation of the first Russian computer program (www.carotidscore.ru) for risk stratification of postoperative complications of carotid endarterectomy (CEE). MATERIAL AND METHODS: The present study is based on the analysis of a multicenter Russian database that includes 25,812 patients after CEE operated on from 01/01/2010 to 04/01/2022. The following types of CEE were implemented: 6814 classical CEE with plastic reconstruction of the reconstruction zone with a patch; 18,998 eversion CEE. RESULTS: In the hospital postoperative period, 0.18% developed a lethal outcome, 0.14%-myocardial infarction, 0.35%-stroke. The combined endpoint was 0.68%. For each factor present in patients, a predictive coefficient was calculated. The prognostic coefficient was a numerical indicator reflecting the strength of the influence of each factor on the development of postoperative complications. Based on this formula, predictive coefficients were calculated for each factor present in patients in our study. The total contribution of these factors was reflected in "%" and denoted the risk of postoperative complications with a minimum value of 0% and a maximum of 100%. On the basis of the obtained calculations, a computer program CarotidSCORE was created. Its graphical interface is based on the QT framework (https://www.qt.io), which has established itself as one of the best solutions for desktop applications. It is possible not only to calculate the probability of developing a complication, but also to save all data about the patient in JSON format (for the patient's personal card and his anamnesis). The CarotidSCORE program contains 47 patient parameters, including clinical-demographic, anamnestic and angiographic characteristics. It allows you to choose one of the four types of CEE, which will provide an accurate stratification of the risk of complications for each of them in person. CONCLUSION: CarotidSCORE (www.carotidscore.ru) is able to determine the likelihood of postoperative complications in patients undergoing CEE.
RESUMEN
OBJECTIVE: To analyze in-hospital and long-term results of eversion carotid endarterectomy (CEE), carotid endarterectomy with patch repair and carotid artery stenting (CAS) in patients with high bifurcation of common carotid artery. MATERIAL AND METHODS: A retrospective multiple-center open study included 1983 patients who underwent internal carotid artery (ICA) repair for severe stenosis between 2010 and 2021. Three groups of patients were distinguished depending on revascularization option: group 1 (n=638) - eversion CEE; group 2 (n=351) - CEE with patch repair; group 3 (n=994) - CAS. RESULTS: In-hospital postoperative mortality and incidence of stroke and myocardial infarction were similar. All bleedings (n=39) occurred after CEE. ICA thrombosis was diagnosed in groups 1 and 2 due to intimal detachment after insertion of temporary bypass tube. Incidence of laryngeal paresis, neuropathy of hypoglossal and glossopharyngeal nerves, Horner syndrome, damage to salivary glands was comparable in groups 1 and 2. Long-term mortality was the highest (n=10; 2.8%) after CEE with patch repair due to fatal stroke. In turn, the highest incidence of ICA restenosis and restenosis-induced ischemic stroke was observed after CEE with patch repair and CAS. CONCLUSION: 1. Classical and eversion CEE in patients with high CCA bifurcation is followed by high in-hospital incidence of damage to cranial nerves and salivary glands, laryngeal paresis, Horner syndrome, bleeding and risk of ICA thrombosis. 2. In patients with high CCA bifurcation, CAS and CEE with patch repair are accompanied by high incidence of ICA restenosis, restenosis-induced stroke and mortality in long-term postoperative period. 3. Eversion CEE demonstrates the lowest rates of all adverse cardiovascular events in long-term follow-up period.

OBJECTIVE: To analyze the dynamics of systolic blood pressure (SBP) and the results of various types of carotid endarterectomy (CEE) in patients with resistant arterial hypertension (RAH). MATERIALS AND METHODS: The study included 1577 patients with hemodynamically significant stenosis of the internal carotid artery (ICA) and RAH for more than 3 years. Patients were enrolled from January 2014 to December 2020. Depending on the implemented revascularization strategy, 5 groups were formed: group 1 (n=289 (18.3%)) with classical CEE with plasty of the reconstruction zone with a patch, group 2 (n=472 (29.9%)) with eversional CEE with cut-off of carotid glomus (CG); group 3 (n=109 (6.9%)) with the formation of a new bifurcation; group 4: (n=117 (7.4%)) with autoarterial reconstruction; group 5: (n=590 (37.4%)) with glomus-saving CEE. RESULTS: In the postoperative period, no significant differences were obtained in the frequency of deaths (0.34% for group 1; 0.63% for group 2; 0% for groups 3, 4 and 5), myocardial infarction (0.34%, 0.84%, 1.83, 0.85%, 0.33%, respectively); ischemic stroke (0.34%, 1.27%, 0.91%, 0.85%, 0.17%, respectively), hemorrhagic transformation (0%, 0.84%, 0.91%, 0.85%, 0%, respectively). However, according to the frequency of the combined endpoint (death + myocardial infarction + ischemic stroke + hemorrhagic transformation), the lowest rates were observed in the group of classical carotid endarterectomy with plasty of the reconstruction zone with a patch and glomus-sparing CEE (1.03%, 3.6%, 3.67%, 2.56%, 0.5%, respectively). This is due to the absence of cases of labile AH and hypertensive crises among patients of groups 1 and 5, which was ensured by the preservation of carotid glomus (CG). As a result, the number of patients with 2 and 3 degrees of hypertension in these groups decreased statistically significantly. The vast majority of patients after these operations achieved a stable target SBP. In groups 2, 3, and 4, there was a statistically significant increase in the number of patients with 2 and 3 degrees of AH, which is associated with excision of the CG. CONCLUSION: Classical CEE and glomus-sparing CEE techniques make it possible to achieve a stable target SBP level in patients with RAH as a result of CG preservation. Removal or traumatization of the latter during eversional CEE, the formation of a new bifurcation, autoarterial reconstruction is accompanied by the development of labile hypertension, an increase in the degree of hypertension and a high risk of hemorrhagic transformation in the brain. Thus, the most effective and safe types of CEE in the presence of RAH are classical CEE with plasty of the reconstruction zone with a patch and glomus-sparing CEE.

The article describes the clinical case and analyzes the literature concerning endoprosthesis replacement in the case of traumatic thoracic aortic injury in polytrauma. Current strategy of diagnostics and treatment of patient in critical condition with rupture of isthmic aortic part is based on the principle of multistage surgical treatment (damage control orthopedic). The external fixation of multiple pelvis and extremities fractures and on-time implantation of stent-graft in thoracic aortic part were performed at first hours after the admission. A condition of the patient was stabilized. The delayed reconstructive operations on pelvis and extremities bones allowed obtaining the satisfactory functional result. The principles of staged surgical treatment and the use of on-time high-technology methods allowed saving life for the patient even in critical situation in I level traumatologic centre.

Examinations and operations on 36 ischemic heart disease patients with postinfarction aneurysm of the left ventricle (PIALV) in combination with hemodynamically significant obliterating atherosclerosis of the lower extremity arteries were performed in the clinic during the period from 1995 through 2005. The first stage of the treatment included resection of PIALV and myocardium revascularization. Positive results were obtained in all 36 patients at the first stage of surgical treatment, without ischemia of the myocardium being observed in the postoperative period. The contractive function of the left ventricle as an ejection fraction due to resection of PIALV and its plasty was on average 17% greater, which created favorable conditions for the following stage of surgical treatment. At the second stage of surgery an individual approach was used for patients with generalized atherosclerotic lesions of the lower extremities with special reference to specific clinical picture, as well as non-standard surgical methods. Among the nonstandard surgical methods there were transprosthetic aortotomic shunts and the method of a reverse formation of anastomoses.

Under observation there were 14 male patients. Since 1995 a method of transprosthetic aortotomy has been used in patients with impaired carotid arteries, later this method was used in patients with postinfarction aneurysms of the left ventricle. In addition, in 3 critical patients we used minimally invasive techniques of surgery in stage-wise treatment. Single-stage operations in ischemic heart disease patients with postinfarction aneurysms of the left ventricle and a lesion of the brachiocephalic arteries (BCA) are indicated in the following cases: 1. In intrathoracal lesion of BCA; 2. In atherosclerotic lesion of the left coronary artery trunk; 3. In patients with postinfarction aneurysms of the left ventricle and with output fraction less than 35%; 4. When instable angina is not amendable to medicinal stabilization.

The purpose of the research was to give a topographical substantiation of the choice of an approach to the extracranial internal carotid artery (ICA) in view of individual anatomical variability of ICA and various localizations of stenosis or occlusion. In 38 human corpses ICA was uncovered using operative methods proposed by Cooper. DePalma, Pauliukas and Nelson. A comparative estimation of the approaches was given with calculation of standard parameters of the operative wound. It was established that the approach to the subcranial ICA was dependent on the type of constitution, features of the anatomical shape of the mandible, distance between the mandibular angle and mastoid process. The statistical processing of the findings has shown that all the factors in question made up 91.5% which is enough for the mathematical description of the position of ICA. Regression models of accessibility of the ICA segment for each of the four investigated approaches were made. The PC program for Windows 95/NT which allows the estimation of accessibility of ICA in each patient before operation was created. These mathematical models were used in the clinic for surgical treatment of the ICA pathology in 24 patients. The difference between the calculated data of ICA accessibility and intraoperative measurements was +/- 3 mm. It demonstrates reliability of the estimation of the approach parameters before operation.
