Повышение венозного давления в ВПВ и отсутствие своевременного лечения приводит не только к серьезным осложнениям, но и к летальному исходу. За последние годы этиология СВПВ резко изменилась, главным образом из-за увеличения количества имплантируемых внутрисосудистых устройств (центральные венозные катетеры, электрокардиостимуляторы, дефибрилляторы и др. устройства). Эндоваскулярные методы получили широкие применение в лечении пациентов с СВПВ. В первую очередь этому способствовали малоинвазивность вмешательства, высокий технический успех операции (восстановление просвета вены) и быстрое наступление клинического улучшения. Пациенты, у которых СВПВ развился после имплантации устройств, преимущественно молодого возраста и имеют более высокую продолжительность жизни. При выборе метода лечения крайне важно учитывать эти факторы и отдавать предпочтение тем методам, которые позволяют обеспечить долгосрочный эффект с наименьшим количеством возможных осложнений. В статье представлен клинический случай эндоваскулярного лечения пациентки с окклюзией ВПВ, развившейся спустя 9 лет после имплантации электрокардиостимулятора, с применением методов внутрисосудистой визуализации.</p></abstract><trans-abstract xml:lang="en"><p>Superior vena cava syndrome (SVCS) is due to impaired venous outflow from the head, neck, limbs and upper half of the body into the right atrium due to stenosis or complete obstruction of the superior vena cava (SVC). Increased venous pressure in the SVC and lack of timely treatment leads not only to serious complications, but also to death. In recent years, the etiology of SVCS has changed dramatically, mainly due to an increase in the number of implanted intravascular devices (central venous catheters, pacemakers, defibrillators, and other devices). Endovascular methods have become widely used in the treatment of patients with SVCS. This was primarily due to the minimally invasive nature of the intervention, the high technical success of the operation and the rapid onset of clinical improvement. Patients who develop SVCS after device implantation are predominantly younger and have a longer life expectancy. When choosing a treatment method, it is extremely important to take these factors into account and give preference to methods providing a long-term effect with the fewest possible complications. The article presents a case of endovascular treatment of a patient with SVCS occlusion, which developed 9 years after pacemaker implantation, using intravascular imaging methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром верхней полой вены</kwd><kwd>электрод-ассоциированный синдром верхней полой вены</kwd><kwd>ангиопластика верхней полой вены</kwd><kwd>стентирование верхней полой вены</kwd><kwd>экстракция электродов</kwd><kwd>имплантируемые устройства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>superior vena cava syndrome</kwd><kwd>lead-related superior vena cava syndrome</kwd><kwd>superior vena cava angioplasty</kwd><kwd>superior vena cava stenting</kwd><kwd>lead extraction</kwd><kwd>implantable devices</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rice TW, Rodriguez RM, Light RW.
