Преимущество порт-систем над другими видами сосудистых доступов связано с минимизацией ранних осложнений, однако поздние осложнения по-прежнему остаются актуальными. В статье приведены клинические случаи поздних порт-ассоциированных осложнений, тактика ведения пациентов при их возникновении и возможные исходы. Проведена оценка частоты встречаемости поздних осложнений внутривенных порт-систем. Наиболее распространенными осложнениями являются инфекции, тромбозы и механические повреждения (защемление и фрагментация катетера - pinch-off-синдром, повреждение портальной камеры, дислокация камеры и катетера порт-системы и др.), которые могут стать причиной прерывания специализированного лечения, неэффективности противоопухолевой терапии, повлиять на исход заболевания и стать причиной летального исхода. К редким осложнениям относят такие, как прорезывание камеры (пролежень мягких тканей в области камеры порта) и экстравазацию цитостатических препаратов. Ключевым аспектом профилактики поздних порт-ассоциированных осложнений является соблюдение, как медицинским персоналом, так и самим пациентом, рекомендаций по уходу за системами длительного венозного доступа, изложенных в действующих клинических протоколах.</p></abstract><trans-abstract xml:lang="en"><p>   Currently, in oncological practice, the installation of fully implantable intravenous port systems has become most often used to provide central vascular access. The advantage of port systems over other types of vascular access is associated with minimizing very early and early complications, but late complications are still relevant. The article presents clinical cases of late port-associated complications, patient management tactics in case of their occurrence and possible outcomes. The frequency of late complications of intravenous port systems was assessed. The most common complications are infections, thrombosis and mechanical damage (pinching and fragmentation of the catheter - pinch-off syndrome, damage to the portal chamber, dislocation of the chamber and catheter of the port system, etc.), which can cause interruption of specialized treatment, ineffectiveness of antitumor therapy, affect the outcome of the disease and cause death. Rare complications include such as eruption of the chamber (bedsore of soft tissues in the area of the port chamber) and extravasation of cytostatic drugs. A key aspect of the prevention of late port-associated complications is compliance, both by medical personnel and by the patient himself, with the recommendations for the care of long-term venous access systems set out in current clinical protocols.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутривенная порт-система</kwd><kwd>порт-ассоциированные осложнения</kwd><kwd>противоопухолевая терапия</kwd><kwd>тромбоз</kwd><kwd>инфекция</kwd><kwd>механические повреждения порт-систем</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intravenous port system</kwd><kwd>port-associated complications</kwd><kwd>antitumor therapy</kwd><kwd>thrombosis</kwd><kwd>infection</kwd><kwd>mechanical injuries of port systems</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Silberzweig J., Sacks D., Khorsandi A., et al.
