Résumé
Background: Acute myocarditis corresponds to an acute inflammation of the myocardium whose origin is most often viral. Several viruses can be incriminated to note the parvovirus B19, the virus herpes of the group 6 and to a lesser degree the virus of the hepatitis C (VHC) [18,19]. Since 2019 and with the discovery of SARS COV2 some cases of myocarditis associated with covid have been noted, this last association is rare and is present in only 5% of cases [8]. The diagnosis of myocarditis is sometimes difficult and can lead to confusion with acute coronary syndrome, especially in cases of ST-segment elevation on the EKG, hence the interest of magnetic resonance imaging, which has made it possible in recent years to reduce the rate of unnecessary coronary angiography, especially in the case of young subjects with no cardiovascular risk factors. in this context we report the case of a 33 year old patient with no cardiovascular risk factors and no medical or surgical antecedents who was admitted to the emergency department for the management of acute chest pain related to acute post-covid myocarditis, the patient was initially admitted to the cardiology intensive care unit where he was put in condition and under analgesic treatment and under therapeutic protocal of covid 19 and under anticoagulation based on low molecular weight heparin at preventive dose with a good clinical evolution he was transferred thereafter to the clinical cardiology then declared outgoing under treatment of covid 19 with an appointment of control in 1 month.
Résumé
Background and aims: The initiation of a global mass vaccination against COVID-19 seems to decrease mortality and hospitalization for vaccinated people. However, side effects may occur. This short review illustrates some cases of vascular complications following the COVID-19 vaccination, affecting young people with ischemic, embolic complications or a combination of the two. Patients and methods: Observation 1: a 46 years old woman consulted for a sudden left sided hemiparesis seven days following the second dose of covid-19 vaccine. The initial brain scan was normal and she received thrombolytic treatment. Control scan showed signs of ischemic stroke of right superficial cerebral artery with haemorrhagic transformation. Supra-aortic ultrasound was performed showing a fresh mobile thrombus with complete obstruction of the right internal carotid artery. Observation 2: a 52 year old patient admitted for accute dyspnea, three days after receiving the third dose of covid-19 vaccine. CT angiography revealed a thrombosis of left pulmonary artery. Five days later, an ischemic vascular accident occurs confirmed by CT scan, so we made a supra-aortic ultrasound revealing a thrombosis of right proximal internal carotid artery. Discussion and results: Incidence of vascular complications due to the covid 19 vaccination is discussed with possible hypotheses. Conclusions: COVID-19 vaccines are considered safe since the proven benefits of vaccination in protecting against COVID-19. Nonetheless, health professionals must be aware of all possible complications, early diagnosis and quick initiation of the appropriate treatment may enhance the outcome. (Figure Presented).
