[Endovascular treatment of deep vein thrombosis of the upper extremities]. / Endovaskulyarnoe lechenie trombozov glubokikh ven verkhnikh konechnostei.

OBJECTIVE: To improve the results of treatment of deep vein thrombosis of the upper extremities sing endovascular technologies. MATERIAL AND METHODS: We analyzed safety and effectiveness of treatment in 24 patients with deep vein thrombosis of the upper extremities. All ones were divided into 2 homogeneous groups by 12 people each. In the first group, conventional anticoagulation was performed. In the second group, we used additional regional catheter thrombolysis with alteplase and, if necessary, venous stenting or balloon angioplasty for residual stenosis. Patients received apixaban at baseline and throughout 6 postoperative months. After 12 months, we performed ultrasound and clinical examination to identify deep vein patency and venous outflow disorders. Vein recanalization was evaluated as follows: <50% - minimal, 50-99% - partial, 100% - complete. The quality of life of patients was studied using the SF-36 questionnaire. RESULTS: In the first group, we observed complete vein recanalization in 25% of cases, partial - in 33%, minimal - in 41% of cases; in the second group - 83.3% and 16.7% of patients, respectively. In the first group, clinical manifestations of venous outflow disorders were absent in 25% of patients, mild disorders - 25%, moderate - 8.3%, severe - 41.7% of patients. In the second group, venous outflow was not impaired in 83.7% of patients, mild violations occurred in 16.7% of patients. In the first group, physical health was equal to 44.2±1.7 scores, psychological health - 49.3±2.3 scores; in the second group - 69.3±5.7 and 71.3±5.4 scores, respectively. CONCLUSION: Endovascular treatment improved postoperative outcomes.

[Cardiac ruptures in acute myocardial infarction]. / Razryvy serdtsa pri ostrom infarkte miokarda.

Presented in the article are the generalized data of the Russian and foreign literature addressing the currently important problem of myocardial ruptures as one of the most dangerous complications of infarction, also analysing the results of clinical studies on interconnection of heart ruptures with systemic thrombolytic therapy and with a percutaneous coronary intervention. This is followed by describing the mechanisms that may lead to myocardial rupture during thrombolytic therapy and surgical endovascular treatment, underlying the necessity of pharmacological pre- and post-conditioning for prevention of reperfusion myocardial lesions. The article also touches upon the clinical and instrumental diagnosis of myocardial ruptures, as well as approaches to surgical treatment depending on the type of rupture and necessity of myocardial revascularization.

[Acute cerebral circulation impairment associated with percutaneous coronary intervention]. / Ostroe narushenie mozgovogo krovoobrashcheniia, assotsiirovannoe s chreskozhnym koronarnym vmeshatel'stvom.

The article deals with generalized literature data on the current importance of the problem concerning acute cerebral ischemia occurring during percutaneous coronary interventions. Pathophysiological mechanisms of the development of acute cerebral circulation impairment are described, with their classification. Also considered are various risk factors which may cause this formidable complication, followed by describing modern methods of its surgical treatment. It is noted that the main risk factors for neurological complications appearing after revascularization of coronary arteries include age, accompanying diseases (instability of arterial pressure, diabetes mellitus, atrial fibrillation, atherorosclerotic lesions of the aorta and brachiocephalic arteries, previous stroke), as well as systolic dysfunction, leukocytosis, and a low level of cognitive function prior to operation. The development of acute cerebral circulation impairment during and after percutaneous coronary intervention is an indication for using methods of endovascular treatment. It is most appropriate to use a combination of direct percutaneous thrombectomy and a stent retriever. It is underlined in the article that removal of the thrombus form the cerebral artery is not an independent surgical procedure but rather a methodology envisaging an operation to be performed from the simplest technique to the most complicated one. As the first procedure, it is necessary to perform thrombaspiration and then, if ineffective, a second stage consisting in thrombextraction with the help of a stent retriever. Besides, in order to increase efficacy of thrombaspiration there have been worked out several techniques combining the use of direct thrombextraction and a stent retriever. Described in detail are 4 most commonly used techniques.

[Endovascular interventions in true and false aneurysms of hepatic, splenic and renal arteries].

A false aneurysm of visceral arteries is a life-threatening pathology sufficiently difficult to treat. Open operations are characterised by a large scope, considerable surgical injury and accompanied by a high rate of serious complications. The development of the technology of superselective catheterization of blood vessels, creation of specialized microcatheters, glue composites and various types of spirals made it possible to treat this severe pathology without resorting to open operations. The work deals with a brief literature review concerning epidemiology, methods of diagnosis and treatment of pseudoaneurysms of visceral arteries, followed by presenting three clinical case reports concerning successful treatment of posttraumatic false aneurysms of the right hepatic and splenic arteries, as well as an aneurysm of the renal artery. Both immediate and remote results of endovascular interventions in these patients are followed up, demonstrably showing possibilities of endovascular technologies in treatment of the pathology involved.

[Coronary angioplasty with direct stenting: assessment of primary results and some economical aspects]. / Koronarnaia angioplastika s priamym stentirovaniem: otsenka pervichnykh rezul'tatov i nekotorykh ékonomicheskikh aspektov.

UNLABELLED: Comparison of immediate angiographical and clinical results of direct coronary stenting and stenting after predilation was carried out in 68 patients. Groups of patients subjected to direct stenting and stenting with predilation had similar clinical and angiographical characteristics. Direct stenting was successful in 100%, stenting with predilation--in 97.2% of patients with residual stenosis 5.1 and 4.9%, respectively. There were no cases of stent loss, death or emergent bypass grafting during neither the procedure nor period of hospitalization. There was 1 Q-wave myocardial infarction (2.8%) and 2 non-Q wave myocardial infarctions (1 in each group). Compared with stenting with predilation procedure of direct stenting was associated with significantly shorter procedure duration (39-/+7.1 min, 60-/+12.5 min, respectively), radiation exposure time (7.9-/+6.3 and 13.5-/+8.9 min, respectively), lower workload of the laboratory (4.9-/+3.5 and 6.1-/+2.0 patients/day, respectively), decreased consumption of contrast medium (200-/+71 and 275-/+75.9 ml, respectively), and thus lower overall cost of the procedure. CONCLUSION: Direct coronary stenting is a convenient, safe and economically justified method of stent implantation.
