not-yet-known not-yet-known not-yet-known unknown Conclusion Venous thromboembolism encompasses a range of clinical presentations and outcomes, with RHT being an underdiagnosed but significant complication. RHT can notably impact prognosis, leading to higher mortality and hemodynamic instability. Optimal treatment for RHT remains to be debated due to the lack of randomized studies, though anticoagulation, thrombolysis, and surgical options are considered. Thrombolysis, including ”half-dose” regimens, has shown promising results in resolving RHT while minimizing bleeding risks, as demonstrated in our case. This underscores the necessity for tailored therapeutic approaches based on individual risk assessments and the need for further research to establish standardized treatment protocols for RHT in PE.
