[Carotid endarterectomy in patients with internal carotid artery thrombosis in the acutest period of ischemic stroke with COVID-19]. / Karotidnaya endarterektomiya u patsientov s trombozom vnutrennei sonnoi arterii v ostreishem periode ishemicheskogo insul'ta na fone COVID-19.

OBJECTIVE: Analysis of the results of emergency carotid endarterectomy (CEE) in internal carotid artery (ICA) thrombosis in the acute period of acute cerebrovascular accident (ACVI) in patients with COVID-19. MATERIAL AND METHODS: During the COVID-19 pandemic (April 1, 2020 - May 1, 2021), 43 patients with ICA thrombosis and a positive polymerase chain reaction (PCR) result for SARS-CoV-2 were included in this prospective study. In all cases, CEE was performed in the acutest period of ACVA. These patients were included in group 1. The comparison group was represented by 89 patients who underwent CEE in the acute period of stroke, in the period before the COVID-19 pandemic (April 1, 2019 - March 1.2020). RESULTS: In the hospital postoperative period, the groups were comparable in terms of the incidence of deaths (group 1: 2.3%, n=1; group 2: 1.1%, n=1; p=0.81; OR=2.09; 95% CI=0.12-34.3) myocardial infarction (group 1: 2.3%, n=1; group 2: 0%; p=0.7; OR=6.3; 95% CI=0.25-158.5), CVA (group 1: 2.3%, n=1; group 2: 2.2%, n=2; p=0.55; OR=1.03; 95% CI=0.09-11.,7). ICA thrombosis and hemorrhagic transformations were not recorded. However, in view of severe coagulopathy with ongoing anticoagulant/antiplatelet therapy, patients with COVID-19 more often developed bleeding in the operation area (group 1: 11.6%, n=5; group 2: 1.1%, n=1; p=0.02; OR=11.5; 95% CI=1.3-102.5). CONCLUSION: Emergency CEE in the acute period of stroke is an effective and safe method of cerebral revascularization in case of ICA thrombosis in conditions of COVID-19.

[Catheter-directed thrombolysis in iliofemoral thrombosis and aplasia of the inferior vena cava]. / Kateter-napravlennyi trombolizis pri iliofemoral'nom tromboze i aplazii nizhnei poloi veny.

Demonstrated in the article are the results of catheter-directed thrombolysis in a male patient presenting with bilateral acute iliofemoral venous thrombosis on the background of aplasia of the inferior vena cava. The incidence rate of this pathology is specified, with an emphasis on no recommendations on choosing optimal therapeutic strategy in this cohort of patients. The main causes and complications of the disease are described. The realized policy of revascularization demonstrated its safety and efficacy. The chosen method of correction resulted in a successful outcome of treatment, preventing phlegmasia cerulea dolens. This policy can be recommended as most preferred for patients with acute iliofemoral venous thrombosis on the background of aplasia of the inferior venal cava.
