On the contrary, the presence of emicizumab in the blood and its maintenance of permanent basic hemostasis allow for the reduction of doses and infusion time of bypassing agents. Patients undergoing surgical procedures with a high risk of postoperative bleeding require an additional hemostatic treatment during the first two or three days after the surgery. Then the duration of hemostatic treatment should be determined individually. We recommend the use of recombinant activated factor VII for the prevention/control of postoperative bleeding in patients with hemophilia A with inhibitors who are currently receiving emicizumab or have received it in the past 6 months. If treatment with anti-inhibitor coagulant complex is required, the daily dose should not exceed 100 units/kg. Here we report the first case of laparoscopic appendectomy in an 8-year-old child with hemophilia A with inhibitors receiving prophylactic treatment with emicizumab. The patient's parents gave their consent to the use of their child's data, including photographs, for research purposes and in publications.</p></abstract><trans-abstract xml:lang="ru"><p>Хирургические вмешательства, в том числе с высоким риском послеоперационного кровотечения, у пациентов, получающих профилактическую терапию эмицизумабом, не ассоциированы с большими рисками или техническими сложностями в сравнении с больными, получающими стандартную заместительную терапию. Напротив, наличие эмицизумаба в кровотоке и поддержание с его помощью постоянного базового гемостаза позволяет снизить дозу и продолжительность введения препаратов шунтирующего действия. При проведении хирургических вмешательств с высоким риском послеоперационного кровотечения необходимо обеспечить дополнительный гемостаз в течение 2–3 послеоперационных суток. В дальнейшем решение о продолжительности гемостатической терапии принимается индивидуально. Лучше предпочесть введение рекомбинантного активированного фактора VII для профилактики/остановки послеоперационного кровотечения у пациентов с ингибиторной формой гемофилии А, которые получают эмицизумаб или принимали его в последние 6 мес. В случае необходимости назначения антиингибиторного коагулянтного комплекса запрещено превышать дозу 100 Ед/кг/сут. В данной статье мы представляем первый опыт выполнения лапароскопической аппендэктомии у ребенка 8 лет с ингибиторной формой гемофилии А, получающего профилактическую терапию эмицизумабом. Родители пациента дали согласие на использование информации, в том числе фотографий ребенка, в научных исследованиях и публикациях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hemophilia A</kwd><kwd>emicizumab</kwd><kwd>recombinant activated factor VII</kwd><kwd>bleeding</kwd><kwd>prophylactic treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гемофилия А</kwd><kwd>эмицизумаб</kwd><kwd>рекомбинантный активированный фактор VII</kwd><kwd>кровотечение</kwd><kwd>профилактическая терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
