TRUJILLO-ARAUJO, Ana K.; COSSIO-ZAZUETA, Alfonso; CAMARILLO-NAVA, Víctor M.  e  SERRATO-AULD, Roberto C.. Acute arterial and venous thrombosis in patients infected with COVID-19. Rev. mex. angiol. [online]. 2021, vol.49, n.2, pp.45-50.  Epub 23-Ago-2021. ISSN 2696-130X.


There are recognized complications in patients infected by COVID-19 and thrombotic processes are closely related to infection.


To describe the factors associated with increased risk in thrombotic events in COVID-19.

Material and methods:

Case-control study to identify factors associated with thrombotic processes in patients with COVID-19. Descriptive, comparative and inferential statistics were used, as well as logistic regression. The value of p <0.05 was determined as statistically significant and the statistical program IBM SPSS V.25 was used.


15 cases of acute thrombosis were assesed, 17.5% were arterial and 8.8% were venous, 66.7% (n = 10) were men. Therapeutic anticoagulation and surgical procedures were neccesary. There was an association as a risk factor the fact of presenting some comorbidity (p = 0.005), and prolonged aPTT (p = 0.10), as well as abnormalities in the D-dimer.


Infected patients suffers from hypercoagulability and confers a high risk of thrombosis. Significant elevation of D-dimer may be one of the markers of inflammation. The condition of presenting COVID-19 is not a contraindication for any revascularization procedure, which encourages us to improve our diagnostic and therapeutic behavior in patients with COVID-19 infection.
