Surgical and Endovascular Management of Aortic Thrombosis in COVID-19 and Vaccine-Induced Immune Thrombotic Thrombocytopenia.
Review in Vascular health and risk management, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: COVID-19 has been associated with a hypercoagulable state, leading to various thrombotic complications, including aortic thrombosis, a rare but severe manifestation requiring surgical intervention. Additionally, vaccine-induced immune thrombotic thrombocytopenia (VITT), linked to adenoviral vector vaccines, presents unique surgical challenges due to a heightened risk of thrombosis and bleeding. This review focuses on the surgical management of COVID-19-associated aortic thrombosis and VITT-related large-vessel occlusions. Results: Surgical intervention in COVID-19-associated aortic thrombosis depends on thrombus burden, patient stability, and associated comorbidities. Open thrombectomy, aortic bypass, and hybrid endovascular techniques have been employed, with perioperative anticoagulation being critical to prevent recurrence. High thrombus burden cases often require open repair, while endovascular approaches are preferred in high-risk patients. Mortality rates remain elevated (up to 30%), with post-surgical complications including recurrent thrombosis and limb loss. In VITT cases, surgical revascularization is complicated by thrombocytopenia and a prothrombotic state, necessitating non-heparin anticoagulation and close hematologic monitoring. Delayed diagnosis and inappropriate anticoagulation significantly worsen outcomes. Conclusion: The surgical management of aortic thrombosis in COVID-19 and VITT patients requires a multidisciplinary approach, incorporating vascular surgery, hematology, and intensive care. Early intervention with individualized surgical and anticoagulation strategies is crucial in optimizing outcomes. Further research is needed to refine surgical decision-making, improve postoperative anticoagulation protocols, and enhance patient survival in these complex thrombotic conditions.
