[Successful treatment of high-risk pulmonary embolism with low-dose anticoagulation: a case report].

ABSTRACT

Reperfusion is considered as the cornerstone of the treatment of high-risk pulmonary embolism (PE). However, when thrombolysis is contraindicated and surgery or interventional therapy is not available, the treatment of high-risk PE becomes very difficult. To our knowledge, there are no reports of successful treatment of high-risk PE with low-dose anticoagulation. On November 30, 2021, a 56-year-old male patient with subarachnoid hemorrhage was admitted to the emergency department of the First Affiliated Hospital of Chongqing Medical University. On the second day of admission, the patient suddenly went into shock during aneurysm clipping. After implementing D-dimer, markers of myocardial injury, echocardiography and computed tomography pulmonary angiography, a high-risk PE was diagnosed. Due to the contraindication of thrombolysis and the refusal of endovascular treatment, he was eventually cured with low-dose anticoagulation combined with vasopressors.
