(aged 60 years) was admitted to the department of vascular surgery (Vladivostok). He was diagnosed with Leriche’s syndrome, for which he took 100 mg of aspirin and 75 mg of clopidogrel. On January 12, 2022, combined spinal-epidural anesthesia was performed, and the epidural space was punctured on the fourth attempt. However, massive bleeding was observed from the puncture site. Intraoperatively, before the great vessels were clamped, 100 units/kg of heparin (8000 units) was administered. After the operation, the epidural puncture site was revised: the sticker was soaked with hemorrhagic discharge and removed, and a new sticker was applied. On January 12, 2022, nadroparin calcium 9500 IU anti-Xa/ml 0.3 mL was given two times a day in the ICU. On the same day, intensive bleeding was noted in the area where the epidural catheter was located. This was treated locally with cold and two doses of fresh frozen plasma. On January 13, 2022, magnetic resonance imaging of the lumbar spine showed the spinal cord without displacement and compression, the puncture area had no signs of bleeding, the epidural catheter was removed, and the patient was discharged for outpatient treatment on day 7.</p> <p><bold><italic>CONCLUSION:</italic></bold> To reduce bleeding risk in neuraxial blockade, the recommendations for preparing for surgery patients receiving anticoagulant and antiplatelet therapy must be followed, and the pharmacokinetics of antithrombotic drugs must be taken into account. If puncture and catheterization of the epidural space are technically difficult, manipulation should be abandoned.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование.</italic></bold> Кровотечение в области пункции при нейроаксиальных блокадах — потенциально опасное осложнение, риск которого значительно возрастает у пациентов, получающих антитромботическую терапию.</p> <p><bold><italic>Описание клинического случая.</italic></bold> Пациент С., 60 лет, поступил в отделение сосудистой хирургии Приморской краевой клинической больницы № 1 (Владивосток) с жалобами на боль в икроножных мышцах в покое, чувство онемения и зябкость стоп. Из анамнеза известно, что больной страдает синдромом Лериша; принимал ацетилсалициловую кислоту (100 мг) и клопидогрел (75 мг). 12.01.2022 пациенту выполнена комбинированная спинально-эпидуральная анестезия, пункция эпидурального пространства произведена с 4-й попытки. Обращала на себя внимание повышенная кровоточивость из места пункции. Интраоперационно перед пережатием магистральных сосудов введено 100 ед/кг (8000 ЕД) гепарина натрия. По окончании операции осуществлена ревизия места эпидуральной пункции: наклейка промокла геморрагическим отделяемым, была удалена, наложена новая наклейка. 12.01.2022 в отделении реанимации и интенсивной терапии назначен надропарин кальция в дозе 9500 МЕ, анти-Ха/мл 0,3 мл 2 раза/сут. 12.01.22 зафиксировано интенсивное кровотечение в области нахождения эпидурального катетера. Лечение: местно — холод, 2 дозы свежезамороженной плазмы. По данным магнитно-резонансной томографии поясничного отдела позвоночника, спинной мозг без смещения и компрессии. 13.01.22 — область пункции без признаков кровотечения, эпидуральный катетер удалён. Пациент выписан на амбулаторное лечение на 7-е сут после вмешательства.</p> <p><bold><italic>Заключение.</italic></bold> Для снижения риска развития кровотечения при нейроаксиальных блокадах необходимо придерживаться клинических рекомендаций по подготовке к оперативному лечению пациентов, получающих антикоагулянтную и дезагрегантную терапию, учитывать фармакокинетику используемых антитромботических препаратов. При возникновении технических сложностей, в том числе и после 3 неудачных попыток выполнения пункции и катетеризации эпидурального пространства, как произошло в нашем случае, от манипуляции следует отказаться.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epidural analgesia</kwd><kwd>bleeding</kwd><kwd>anticoagulants</kwd><kwd>antithrombotic drugs</kwd><kwd>complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпидуральная аналгезия</kwd><kwd>кровотечение</kwd><kwd>антикоагулянты</kwd><kwd>антитромботические препараты</kwd><kwd>осложнения</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">Møller MH, Sigurðsson MI, Olkkola KT, et al.
