[Implantation of a fenestriated stent-graft in a patient with thoracic aortic aneurysm]. / Implantatsiya fenestrirovannogo stent-grafta u patsienta s anevrizmoi grudnogo otdela aorty.

The authors present endovascular treatment of a patient with stenosis of the left anterior descending artery, chronic DeBakey type III aortic dissection and thoracic aortic aneurysm. The first stage was percutaneous coronary intervention with stenting of the left anterior descending artery. The second stage implied implantation of a fenestrated stent-graft. The follow-up CT angiography after 6 months revealed occlusion of the left subclavian artery that required stenting. Control CT angiography confirmed adequate stent-graft placement without endoleaks and stenosis of the artery. The choice of these reconstructions and stages of interventions are substantiated. The authors concluded effectiveness of treatment strategy, as well as the need for preventive subclavian artery stenting after implantation of a fenestrated graft.

[Isolated liver perfusion with melphalan followed by pembrolizumab therapy for unresectable metastases of uveal melanoma to the liver]. / Sposob izolirovannoi perfuzii pecheni melfalanom s posleduyushchei terapiei pembrolizumabom v lechenii nerezektabel'nykh metastazov uveal'noi melanomy, ogranichennykh pechen'yu.

Uveal melanoma accounts for 80% of all ocular melanomas, and 30-60% of patients have metastases to the liver. A few patients are candidates for liver resection, and this disease is associated with poor prognosis. There are few data on optimal management of metastatic uveal melanoma. Isolated hepatic perfusion is a perspective method for regional treatment of inoperable metastatic liver lesions with uveal melanoma. We present a patient with uveal melanoma who underwent previous enucleation of the eye. Cancer progressed 15 years later as an isolated inoperable metastatic liver lesion. The patient underwent isolated liver perfusion with melphalan, hyperthermia and oxygenation. Subsequently, the patient received systemic therapy with pembrolizumab. Partial response was achieved 1 month after the procedure. There was no progression for 20 months after surgery under systemic therapy with pembrolizumab. Thus, isolated liver chemoperfusion with melphalan is advisable in these patients.

[Isolated endovascular liver chemoperfusion for liver metastases of uveal melanoma]. / Sposob izolirovannoi endovaskulyarnoi khimioperfuzii pecheni pri metastazakh uveal'noi melanomy v pechen'.

Isolated hepatic perfusion is one of the possible approaches for unresectable liver metastases of uveal melanoma. This technique is rare in modern oncology because of extremely difficult technique and high risk of intra- and postoperative complications. Thus, minimizing surgical trauma and increasing safety and reproducibility of this technique are important. There were 36 procedures of isolated «open¼ hepatic perfusion. The authors describe the first experience of endovascular hepatic perfusion. Advantages and clinical prospects of this method are shown.

CAROTIDSCORE.RU-The first Russian computer program for risk stratification of postoperative complications of carotid endarterectomy.

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.

[Hybrid revascularization in a patient with Covid-19 and chronic limb ischemia stage IV]. / Gibridnaya revaskulyarizatsiya u patsienta s COVID-19, khronicheskoi ishemiei nizhnei konechnosti IV stepeni.

The authors report hybrid treatment of a patient with angina pectoris class II, multiple previous reconstructive interventions on the aortofemoral segment and chronic ischemia of the left lower limb stage IV and concomitant COVID-19. Coronary angiography was performed after regression of infectious disease under antiviral therapy. Occlusion of the left anterior descending artery was observed that required LAD stenting. On the next day, hybrid revascularization of the lower extremities was implemented: thrombectomy and endarterectomy from the branch of the aorto-femoral bypass graft and deep femoral artery at the first stage, stenting of the orifice of proximal branch of aorto-femoral bypass graft at the second stage, endarterectomy from superficial femoral artery, recanalization and stenting of superficial femoral artery and popliteal artery at the third stage and prosthetic- femoral bypass with autologous vein at the fourth stage. Postoperative angiography revealed patent stents and no residual stenoses. The choice in favor of these procedures and step-by-step approach has been substantiated. The authors emphasized effectiveness and safety of this treatment strategy.

[Resection of lumbar arteriovenous malformation]. / Rezektsiya arteriovenoznoi mal'formatsii poyasnichnoi oblasti.

The authors present a 64-year-old patient with lumbar arteriovenous malformation 22´35´50 mm. Open resection under endotracheal anesthesia was carried out. Postoperative period was uneventful. The patient was discharged in 7 days after surgery. Surgical resection of lumbar AVM is preferable because this approach eliminates cosmetic defect without the risk of soft tissue necrosis. Such an invasive intervention can be performed in case of superficial afferent vessel whose ligation will reduce the risk of intraoperative bleeding.

[Subclavian-carotid transposition and subclavian artery stenting for steal-syndrome]. / Podklyuchichno-sonnaya transpozitsiya i stentirovanie podklyuchichnoi arterii v lechenii stil-sindroma.

OBJECTIVE: To analyze in-hospital results of subclavian-carotid transposition and subclavian artery stenting in patients with steal-syndrome. MATERIAL AND METHODS: A retrospective open study included 137 patients with occlusion or severe stenosis of the first segment of subclavian artery and steal-syndrome. The 1st group included 50 patients who underwent stenting or recanalization with stenting of the first segment of subclavian artery between January 2010 and March 2020. The 2nd group included 87 patients who underwent subclavian-carotid transposition between January 2010 and March 2020. RESULTS: There were no in-hospital mortality, myocardial infarction, ischemic stroke or bleeding. In the second group, damage to recurrent laryngeal nerve with irreversible laryngeal paresis occurred in 6.9% of patients, and one patient had brachial plexus neuropathy. One patient developed lymphorrhea with chylothorax accompanied by shortness of breath on exertion. Conservative management with repeated pleural punctures was not accompanied by clinical compensation. The patient was discharged for outpatient treatment. Thromboembolism of the left branch of the aorto-femoral prosthesis and deep femoral artery on the left was diagnosed in the endovascular correction group after implantation of Protege GPS stent (10´60 mm) and post-dilation with a PowerFlex PRO balloon catheter (9´4 mm). Acute ischemia of the left lower limb required thrombectomy with patch repair of deep femoral artery. The patient was discharged after 5 days. In another case, vertebral artery dissection occurred after implantation of Protege GPS stent (10×40 mm) and post-dilatation with a PowerFlex PRO balloon catheter (8´20 mm). In this regard, the patient underwent stenting of the fourth segment of vertebral artery (Endeavor Resolute 4.0´24 mm stent) with post-dilation (Boston Scientific Samurai balloon catheter 0.014´190 cm). The patient was discharged after 3 days. CONCLUSION: Subclavian-carotid transposition and subclavian artery stenting are safe methods of revascularization that are not accompanied by myocardial infarction, ischemic stroke or mortality. However, subclavian-carotid transposition is characterized by higher risk of neurological disorders (laryngeal paresis, phrenic nerve paresis, brachial plexus neuropathy) and wound complications (lymphorrhea, chylothorax). In turn, subclavian artery stenting is associated with the risk of dissection and embolism. Therefore, the choice of treatment strategy in patients with occlusive-stenotic lesions of the first segment of subclavian artery should be personalized and carried out by a multidisciplinary team.

[Computer modeling of the area of carotid endarterectomy with patches of various forms]. / Sposob komp'yuternogo modelirovaniya zony klassicheskoi karotidnoi endarterektomii s primeneniem zaplat razlichnoi formy.

OBJECTIVE: To describe geometric models of carotid artery bifurcation and computer modeling of carotid endarterectomy (CEA) with patches of various configurations. MATERIAL AND METHODS: The method was demonstrated on a reconstructed model of intact vessel based on preoperative CT of the affected vessel in a certain patient. Blood flow is modeled by computational fluid dynamics using Doppler ultrasound data. Risk factors were assessed considering hemodynamic parameters of vascular wall associated with WSS. RESULTS: We studied hemodynamic results of 10 virtual CEA with patches of various shapes on the example of a reconstructed intact artery in a particular patient. Patch implantation is aimed at prevention of carotid artery narrowing since simple suture without a patch can reduce circumference of the artery by 4-5 mm. This result adversely affects blood flow. On the other hand, too wide a patch creates aneurysm-like deformation of internal carotid artery bulb. It is not optimal due to a large recirculation zone. It was found that patch width approximately equal to 3 mm ensures an optimal hemodynamic result. Deviations from this median value, both upward and downward, impair hemodynamics while the absence of a patch results the worst result. CONCLUSION: The proposed computer modeling technique is able to provide a personalized patch selection for CEA with low risk of restenosis in long-term follow-up period.

[Long-term results of carotid endarterectomy and carotid artery stenting in patients with high bifurcation of common carotid artery: a multiple-center study]. / Otdalennye rezul'taty karotidnoi endarterektomii i karotidnoi angioplastiki so stentirovaniem u patsientov s vysokim raspolozheniem bifurkatsii obshchei sonnoi arterii. Rezul'taty mnogotsentrovogo issledovaniya.

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.

[Redo surgery of carotid arteries in patients with contraindications to carotid angioplasty and stenting]. / Redo-khirurgiia sonnykh arterii u patsientov s protivopokazaniiami k karotidnoi angioplastike so stentirovaniem.

AIM: The study was aimed at analysing the in-hospital results of carotid re-endarterectomy and plasty of the zone of reconstruction with a biological patch in patients with haemodynamically significant restenosis and contraindications to carotid angioplasty with stenting. PATIENTS AND METHODS: During the period from 2008 to 2019, we operated on a total of 22 patients presenting with carotid restenosis and found to have contraindications to carotid angioplasty with stenting (an extended lesion, unstable neointima, calcification, pronounced tortuosity). Carotid re-endarterectomy was performed according to the classical technique. The time period after the first intervention to regression of pathology amounted to 48.5±21.3 months. All patients with clinical manifestations of angina pectoris were at the preoperative stage subjected to coronarography, as a result of which in one case a hybrid intervention was performed in the scope of percutaneous coronary intervention and carotid endarterectomy. The endpoints included death, myocardial infarction, acute impairment of cerebral circulation, and lesions of craniocerebral nerves. RESULTS: Carotid re-endarterectomy was most often carried out according to the classical technique with plasty of the zone of reconstruction using a xenopericardial patch. Only in 1 case it was required to perform eversion carotid re-endarterectomy due to tortuosity of the internal carotid artery. During the in-hospital postoperative period no lethal outcomes, myocardial infarctions, nor haemorrhagic complications were registered. One patient was found to develop acute impairment of cerebral circulation. The most frequent complication was unilateral laryngeal paresis caused by lesions of craniocerebral nerves (n=3; 13.6%), with reversible neurological deficit. No cases of either thrombosis/restenosis or elevated pressure gradient in the area of implantation of the xenopericardial patch were revealed. The composite endpoint amounted to 18.2% (n=4). CONCLUSION: The classical carotid re-endarterectomy was not accompanied by cases of thrombosis and restenosis during either the in-hospital or remote period of follow up, however turned out to be associated with a high frequency of the development of complications such as acute impairment of cerebral circulation and lesions of craniocerebral nerves.

[Delayed complication of iliofemoral bypass surgery: giant false aneurysm of distal anastomosis]. / Pozdnee oslozhnenie podvzdoshno-bedrennogo protezrovaniya: gigantskaya psevdoanevrizma branshi proteza v oblasti distal'nogo anastomoza.

We report the results of open surgical correction of a giant false aneurysm of the distal anastomosis in long-term period after iliofemoral bypass surgery. Preoperative diagnostic procedures made it possible to determine the most appropriate treatment strategy. Aneurysm resection was followed by distal anastomosis repair on the right with prosthesis 10 mm. Postoperative imaging is presented. The authors concluded the effectiveness of revascularization strategy.

[Embolization of arteriovenous malformation of the scrotum]. / Embolizatsiya arteriovenoznoi mal'formatsii moshonki.

The authors report a rare disease at the junction of urology and cardiovascular surgery (arteriovenous malformation (AVM) of the scrotum). The options for correction of this disease are discussed. The authors describe the complications of natural course of disease and their treatment. Treatment strategy with AVM embolization is substantiated. Postoperative regression of symptoms is emphasized. The authors concluded safety and effectiveness of interventional correction of this disease.

[Randomized study of tolerability, safety and efficacy of Pletax in intermittent claudication]. / Randomizirovannoe issledovanie perenosimosti, bezopasnosti i éffektivnosti preparata Pletaks pri peremezhaiushcheisia khromote.

AIM: This study was aimed at assessing tolerability, safety and therapeutic efficacy of Pletax® (cilostazol) compared with Trental® (pentoxifylline) in patients with moderate-to-severe intermittent claudication. PATIENTS AND METHODS: The study included a total of one hundred 40-to-65-year-old patients presenting with confirmed diagnosis of moderate-to-severe intermittent claudication. Depending on the therapeutic regimen, the patients were divided into two groups. Group 1: 50 patients orally took Pletax® (cilostazol) at a dose of 100 mg twice daily 30 minutes before meals or 2 hours after meals together with conventional therapy. Group 2: 50 patients took oral Trental® (pentoxifylline) in a dose of 400 mg 3 times daily 30 minutes before meals or 2 hours after meals along with conventional therapy. The duration of the follow up period amounted to 24 weeks for both groups. The treadmill test was carried out at room temperature, with the running track tilt angle of 0° at a speed of 3 km/h. The primary parameters of efficacy were as follows: the dynamics of the minimal walking distance (a distance walked by the patient until the appearance of pain in the extremity) and dynamics of the maximal walking distance (a distance walked by the patients until full stop due to pain in the extremity). RESULTS: Analysing efficacy demonstrated higher results of Pletax® compared with Trental®. The obtained findings suggested that Pletax® showed a significant clinical effect as soon as at 2 weeks, followed by advantage during the whole period of follow up. Analysing the parameters of the minimal and maximal walking distances in the group of patients taking Pletax® demonstrated clear superiority over the Trental® group as soon as by week 2 of administration, which preserved during the whole follow-up period. The minimal pain-free walking distance in the Pletax group at baseline amounted to 92.9±83.4 m (Trental group - 92.3±78.4; p=0.3), followed by an increase at week 8 to 126±115 m (Trental group - 116±96.3; p=0.51), at week 16 to 136±116 m (Trental group - 118±95.5; p=0.04), at week 24 to 149±126 b (Trental group - 127±98.9; p=0.01). At the same time, the effect of Pletax® and Trental® on the secondary parameter of efficacy, i.e., the ankle-brachial index was comparable: at baseline - 0.472 and 0.482 (p=0.28), at 2 weeks - 0.48 and 0.483 (p=031), at 8 weeks - 0.49 and 0.485 (p=0.74), at 16 weeks - 0.494 and 0.492 (p=0.2), at 24 weeks - 0.501 and 0.496 (p=0.45). CONCLUSION: The obtained findings demonstrated advantages of Pletax® over Trental®, manifesting themselves in the achievement of the highest parameters by such criteria as the minimal and maximal walking distance. High safety and efficacy of Pletax® were confirmed by low frequency of unfavourable events during therapy.

[Transposition of internal carotid artery over hypoglossal nerve in eversion carotid endarterectomy]. / Eversionnaya karotidnaya endarterektomiya: transpozitsiya vnutrennei sonnoi arterii nad pod"yazychnym nervom.

OBJECTIVE: To analyze in-hospital and long-term results of eversion carotid endarterectomy (CEE) with transposition of internal carotid artery (ICA) over hypoglossal nerve. MATERIAL AND METHODS: A cohort prospective open-label study included 919 patients with severe ICA stenosis for the period from January 2017 to April 2020. The 1st group (n=172) included patients who underwent eversion CEE with ICA transposition over hypoglossal nerve; the 2nd group (n=747) - who underwent conventional eversion CEE. ICA transposition technique included standard mobilization of the carotid arteries, cross-clamping, arterial wall incision, removal of atherosclerotic plaque and ICA translocation above the hypoglossal nerve for subsequent anastomosis. All patients were examined every 6 months. Mean follow-up period was 17.5±6.9 months. RESULTS: There were no significant between-group differences in cardiovascular morbidity. However, all complications occurred in the 2nd group (traditional eversion CEE). Nevertheless, incidence of adverse events was minimal and combined endpoint did not exceed 0.6% (n=5). Both groups were also comparable by overall incidence of cardiovascular events in long-term period. All ICA restenoses (over 70%) were symptomatic with similar incidence (4 (2.3%) vs. 18 (2.4%), respectively, p=0.83; OR 0.96; 95% CI 0.32-2.88). Mean restenosis-free period was 7.2±2.6 months. In case of significant restenosis, redo CEE with patch repair was performed. There were no cardiovascular complications. All cases of hypoglossal nerve injury occurred in the 2nd group (0 vs. 18 (100%), respectively; p=0.0001; OR 0.003; 95% CI=5.21-0.17) without ICA transposition over the hypoglossal nerve. CONCLUSION: Eversion CEE with ICA transposition over the hypoglossal nerve ensures optimal conditions for successful redo CEE in case of restenosis. This technique facilitates ICA mobilization without hypoglossal nerve injury. This aspect is valuable for successful postoperative outcome and adequate quality of life. ICA transposition is not difficult and does not require additional experience. Transposition per se is not a risk factor of ICA restenosis. Thus, ICA transposition may be routinely recommended in patients eligible for eversion CEE.

[Extended lesion of the internal carotid artery: carotid autotransplantation, creation of a neobifurcation or prosthetic repair?] / Protiazhennoe porazhenie vnutrennei sonnoi arterii: karotidnaia autotransplantatsiia, formirovanie novoi bifurkatsii ili protezirovanie?

AIM: The aim of our investigation was to analyse the results of autotransplantation, creation of a neobifurcation or prosthetic repair of the internal carotid artery during the in-hospital and long-term follow-up periods. PATIENTS AND METHODS: The study included a total of 241 patients presenting with and treated for extended atherosclerotic lesions of the internal carotid artery from 2016 to 2019. The patients were divided into three groups depending on the surgical modality employed: group 1 - autotransplantation of the internal carotid artery (27.8%, n=67), group 2 - creation of a neobifurcation (55.2%, n=133), and group 3 - prosthetic repair of the internal carotid artery (17.0%, n=41). The duration of the postoperative follow-up period amounted to 24.8±11.9 months. The outcome measures selected were as follows: all-cause mortality, myocardial infarction, ischaemic stroke, haemodynamically significant restenosis, and a composite endpoint (death + myocardial infarction + ischaemic stroke + haemodynamically significant restenosis). RESULTS: During the in-hospital postoperative period we registered 1 (2.4%) ischaemic stroke in the group of prosthetic repair, with no significant inter-group difference revealed (p=0.08). In the remote period of follow-up, no statistical differences were revealed for the following outcome measures: all-cause mortality (group 1: 7.5%, n=5; group 2: 10.5%, n=14; group 3: 14.6%, n=6; p=0.49); cardiovascular-related death (group 1: 4.5%, n=3; group 2: 6.7%, n=9; group 3: 12.2%, n=5; p=0.31); myocardial infarction (group 1: 1.5%, n=1; group 2: 3%, n=4; group 3: 4.9%, n=2; p=0.59). However, the patients in the group of prosthetic repair of the internal carotid artery were found to have the highest incidence rates of ischaemic stroke (group 1: 3%, n=2; group 2: 3%, n=4; group 3: 14.6%, n=6; p1-2=0.1; p1-3=0.02; p2-3=0.008), haemodynamically significant restenosis (group 1: 0%, n=0; group 2: 0%, n=0; group 3: 14.6 %, n=6; p1-2>0.99; p1-3=0.000; p2-3=0.000), and higher values of the composite endpoint (group 1: 12 %, n=8; group 2: 16.5%, n=22, group 3: 48.8%, n=20; p1-2>0.99; p1-3=0.000; p2-3=0.000). CONCLUSION: Prosthetic repair of the internal carotid artery for an extended atherosclerotic lesion is a less preferable method compared with autotransplantation and creation of a neobifurcation, as evidenced by the highest incidence rates of ischaemic stroke, haemodynamically significant restenosis, and higher values of the composite endpoint in the remote period of follow up.

[Catheter-directed thrombolysis in iliofemoral thrombosis and aplasia of the inferior vena cava]. / Kateter-napravlennyi trombolizis pri iliofemoral'nom tromboze i aplazii nizhnei poloi veny.

Demonstrated in the article are the results of catheter-directed thrombolysis in a male patient presenting with bilateral acute iliofemoral venous thrombosis on the background of aplasia of the inferior vena cava. The incidence rate of this pathology is specified, with an emphasis on no recommendations on choosing optimal therapeutic strategy in this cohort of patients. The main causes and complications of the disease are described. The realized policy of revascularization demonstrated its safety and efficacy. The chosen method of correction resulted in a successful outcome of treatment, preventing phlegmasia cerulea dolens. This policy can be recommended as most preferred for patients with acute iliofemoral venous thrombosis on the background of aplasia of the inferior venal cava.

[Hybrid revascularization of the brain and myocardium: risk stratification for in-hospital complications]. / Gibridnaia revaskuliarizatsiia golovnogo mozga i miokarda: stratifikatsiia riska gospital'nykh oslozhnenii.

AIM: The study was aimed at determining efficacy of a new computer program of stratification of the risk for postoperative adverse cardiovascular events in patients with atherosclerotic lesions of coronary and carotid arteries. PATIENTS AND METHODS: Based on a mathematical analysis of the outcomes of treatment of patients with atherosclerotic lesions of coronary and carotid arteries over the period from 2011 to 2015, we created a program making it possible to determine a staged or simultaneous policy of revascularization, which was retrospectively and prospectively tested in our medical facility. RESULTS: Within the frameworks of a clinical example we carried out hybrid revascularization of the brain and myocardium in the scope of percutaneous coronary intervention and carotid endarterectomy. During the early postoperative hours, the development of myocardial infarction was registered. According to the program's calculations, in using other strategies of surgical treatment (carotid endarterectomy + coronary artery bypass grafting and carotid endarterectomy - coronary artery bypass grafting), the level of risk for the development of a complication was lowest. Thus, taking into consideration this risk stratification by a multidisciplinary team made it possible to avoid the development of complications. CONCLUSION: This program of decision-making regarding revascularization for atherosclerotic lesions of coronary and carotid arteries may be an additional tool in the armamentarium of the methods of determining therapeutic strategy for this patient cohort.
