A Rare Case of Stroke as a Complication After Percutaneous Mechanical Thrombectomy in a Patient with Intermediate-High Risk Pulmonary Embolism and Patent Foramen Ovale.

Unlabelled: We present an extremely rare case of a patient with intermediate-high risk pulmonary embolism treated with percutaneous mechanical thrombectomy, complicated with stroke as a form of paradoxical embolism through a previously unknown patent foramen ovale. We reviewed the literature for indications, efficacy, and safety of this procedure, as well as for experience on this technique in patients with patent foramen ovale.

Learning Points: Some authors propose percutaneous mechanical thrombectomy as an aggressive treatment of intermediate-high risk pulmonary embolism.

[Risk of thrombosis recurrence among patients with COVID-19- and surgery-associated venous thromboembolism].

Introduction: Recent surgery is a well-known major transient risk factor for venous thromboembolism (VTE) due to the low risk of VTE recurrence after anticoagulation is discontinued. On the other hand, the risk of VTE recurrence among patients with COVID-19-associated VTE is unknown. This study aimed to compare the risk of VTE recurrence between patients with COVID-19- and surgery-associated VTE.
