Low-Dose Catheter-Directed Thrombolysis for Massive Pulmonary Embolism: A Case Report Highlighting Dosing Considerations in Asian Patients.
Article in Case reports in cardiology, 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
Clinical management of massive pulmonary embolism is challenging when active hemorrhage, a contraindication to thrombolytics, is concurrently present. We describe a successful attempt in using low-dose catheter-directed thrombolysis (CDT) in a high-risk patient with absolute contraindications to systemic thrombolysis. A 69-year-old Asian female with cardiac arrest was brought to a resource-limited rural hospital. The patient underwent 50 min of cardiopulmonary resuscitation (CPR) before regaining the pulse but remained in cardiogenic shock. Computerized tomography (CT) of the chest found massive PE. The patient was found with multiple fractures and subarachnoid hemorrhage. Catheter-directed embolectomy was performed without clinical improvement. A low-dose CDT with alteplase was attempted by giving 5 mg over 2 h with a repeated session 24 h later for a total of 10 mg. The patient started improving, was extubated on Day 9, and transferred out of the ICU on Day 15. Low-dose CDT in massive PE could be lifesaving despite the presence of absolute alteplase contraindications. Patients with contraindications, a high risk of bleeding, or of Asian race may benefit more from the low-dose alteplase regimen.
