[Structure of in-hospital and remote complications of surgical treatment of stenotic lesions of coronary and carotid arteries]. / Struktura gospital'nykh i otdalennykh oslozhnenii khirurgicheskogo lecheniia stenoticheskikh porazhenii koronarnykh i sonnykh arterii.

BACKGROUND: Problems concerning the choice of optimal revascularization strategy in patients with simultaneous atherosclerotic lesions of the coronary and brachiocephalic arteries still remain unsolved, since there are no randomized studies and there is uncertainty in Russian and foreign guidelines. AIM: The study was aimed at analysing the remote results of surgical treatment of 391 patients with concomitant lesions of the coronary and brachiocephalic arteries within the framework of a single-centre prospective registry. PATIENTS AND METHODS: Within the timeframe of our study, all patients were divided into 4 groups depending on the method of surgical treatment of the above-mentioned pathology of the coronary and brachiocephalic arteries. Group 1 patients underwent staged surgery in the scope of coronary artery bypass grafting followed by carotid endarterectomy. Group 2 patients endured coronary artery bypass grafting combined with carotid endarterectomy. Group 3 patients were subjected to hybrid revascularization consisting in percutaneous coronary intervention and carotid endarterectomy. Group 4 patients sustained staged surgery consisting of carotid endarterectomy followed by coronary artery bypass grafting. The clinical and demographic characteristics, period of follow up, as well as the results after the respective surgical intervention for each group are presented. RESULTS: We analysed the frequency and structure of adverse cardiovascular events depending on the time intervals within which complications had occurred resulting from a particular surgical policy used. DISCUSSION: The obtained findings demonstrated that adverse cardiovascular events in the total sample of patients were mainly observed in the remote period of follow up, which was related primarily to a progressive course of atherosclerosis, the presence of bilateral lesions of the internal carotid arteries, as well as the lack of protocols ensuring complete revascularization in multifocal atherosclerosis within a limited time interval. CONCLUSION: We made a conclusion on efficacy of the simultaneous strategy of revascularization by means of coronary artery bypass grafting combined with carotid endarterectomy in regard to decreased incidence of strokes in the remote period of follow up.

[Surgical treatment of a patient with saccular arterial aneurysm of the cavernous-ophthalmic segment]. / Khirurgicheskoe lechenie bol'nogo s meshotchatoi arterial'noi anevrizmoi kavernozno-oftal'micheskogo segmenta.

Presented in the article are the results of surgical management of a patient with an extremely rare pathology - a saccular arterial aneurysm of the cavernous-ophthalmic segment of the left internal carotid artery. We performed multistage open surgical intervention in the following scope: osteoplastic pterional craniotomy on the left, creation of a wide-lumen anastomosis between the left external carotid artery and M2 segment of the left middle cerebral artery with the use of the radial artery, ligation of the cervical portion of the left internal carotid artery and clipping of its supraclinoid portion. The chosen surgical policy made it possible to create sufficient volumetric blood flow through the shunt, comparable to the blood flow through the internal carotid artery, which helped avoid ischaemic stroke after exclusion of the aneurysm from circulation. A conclusion was drawn on efficacy of this method of treatment.

[Results of coronary artery bypass grafting in patients of different age groups]. / Rezul'taty koronarnogo shuntirovaniia u patsientov raznykh vozrastnykh grupp.

BACKGROUND: Myocardial revascularization involves a wide range of invasive strategies aimed at treating ischaemic heart disease in patients of different age groups. AIM: The purpose of the present study was to analyze the outcomes of coronary artery bypass grafting in patients depending on age. PATIENTS AND METHODS: A total of 905 patients enrolled in our study were subdivided into groups based on age-related characteristics (young age, middle age, old age, senile age). The endpoints of follow up were as follows: myocardial infarction, acute impairment of cerebral circulation, death and haemorrhagic complications. RESULTS: It should be mentioned that the groups were comparable by the majority of the parameters studied. No statistically significant differences in the frequency of the development of complications in the postoperative period were observed. However, amongst patients over 75 years old, revision of the mediastinum for haemorrhage was performed more often. DISCUSSION: Patients of different age groups undergoing coronary artery bypass grafting are extremely heterogeneous by the clinical, anamnestic, instrumental and intraoperative characteristics. A high frequency of haemorrhagic complications amongst patients over 75 years old may be explained by a more aggressive approach to the regimens of anticoagulant/antiaggregant therapy resulting form the presence of atrial fibrillation. In its turn, this fact determines the probability of a high frequency of the development of adverse cardiovascular events. An individual approach to the choice and scope of the strategy of revascularization in patients of different age groups is the fundamental principle for an optimal outcome of coronary surgery. CONCLUSION: The obtained findings and analysis of the statistical data are indicative of the necessity of personified selection of the technique of a surgical intervention for each particular patient, which will make it possible to decrease the rate of adverse cardiovascular events in the postoperative period.

[In-hospital outcomes of transcutaneous coronary intervention and carotid endarterectomy in hybrid and staged regimens]. / Gospital'nye rezul'taty chreskozhnogo koronarnogo vmeshatel'stva i karotidnoi éndarteréktomii v gibridnom i poétapnom rezhimakh.

The aim of this study was comparative assessment of in-hospital outcomes after hybrid and staged surgical management of patients presenting with haemodynamically significant lesions of the coronary (CA) and brachiocephalic arteries (BCA) treated by means of either endovascular or surgical techniques. Over the period from 2010 to 2017, we operated on a total of 197 patients with stenotic lesions of the carotid and coronary arteries. The strategy of revascularization included transcutaneous coronary intervention (TCI) and carotid endarterectomy (CEA). Of these, 73 (37%) patients underwent staged revascularization of the brain and myocardium in various sequence (TCI-CEA or CEA-TCI), with a mean interval between the operations amounting to 9.89±7.36 months. Unfavourable outcomes were regarded as the development of such significant cardiovascular events as myocardial infarction (MI), acute impairment of cerebral circulation, death, repeat unplanned revascularization. For hybrid strategy (TCI+CEA) the index period of assessing the outcomes was the single in-hospital period, whereas for the staged strategy it was the time period beginning from the in-hospital period of the primary operation and ending by the in-hospital period of the second stage. The groups were comparable by the absolute majority of the parameters. More than half of the patients were elderly males. One third had a history of MI. The findings of coronary angiography most often revealed lesions of 1-2 CAs. The average parameters of carotid artery stenosis, according to the BCA angiography varied from 74.9 to 82.6%, with bilateral occlusive stenotic lesions being revealed in every third patient. In connection with more frequent involvement of 1-2 CAs the patients underwent implantation of 1-2 stents. In our sample we used a total of 247 stents. Of these, 119 were uncoated and 128 were drug-eluting stents. No between-group significant differences in the development of unfavourable cardiovascular events during the in-hospital postoperative period were revealed. However, despite this, a pronounced negative tendency of the complication rate was noted in the group of staged revascularization. Non-optimal time intervals between the stages of the operations in a third of cases exceeded one year on the patient's own initiative. Nearly a quarter of patients did not come for the second stage of revascularization. An important finding of our study was no increase in the risk of stent thrombosis in hybrid operations compared with the staged approach, despite administration of a loading dose of clopidogrel after CEA, but not before TCI. Another significant result was the fact of greater availability of revascularization of the myocardium and the brain within the framework of the hybrid strategy as compared with the staged one, which may play an important role in prevention of ischaemic unfavourable events in the remote period of follow up.

[Carotid endarterectomy: three-year results of follow up within the framework of a single-centre register]. / Karotidnaia éndarteréktomiia: trekhletnie rezul'taty nabliudeniia v ramkakh odnotsentrovogo registra.

The purpose of the study was to determine the incidence rate and structure of cardiovascular complications in patients presenting with lesions of the carotid arteries and multifocal atherosclerosis, having endured carotid endarterectomy (CEA), during a three-year period within the framework of a single-centre register. The study included a total of 1,035 patients subjected to CEA over the period from 2011 to 2016. The duration of the long-term follow up averagely amounted to 42.4±18.6 months. The outcome measures assessed were as follows: death, myocardial infarction (MI), acute cerebral circulation impairment (transitory ischaemic attack) [ACCI (TIA)], clinically significant haemorrhage according to the BARC scale, unplanned repeat revascularization. In the remote period of follow up, the mortality rate did not exceed 2.3%. Of the unfavourable outcomes, most frequently observed turned out to be ACCI (TIA), with less often observed being MI. Two times a year, all patients underwent duplex scanning of the carotid arteries, whose findings revealed haemodynamically significant restenosis in 3.28% of cases. The average period of formation of restenosis amounted to 14.0±3.1 months after the operation. Three patients underwent repeat CEA and a further 16 patients endured stenting of the internal carotid artery (with 2 patients having developed intraoperative TIA). In the remote period, no cases of secondary restenosis were revealed this group of patients. It was determined that restenosis more often developed in patients having sustained classical.
