Pulmonary glue embolism mimicking thrombotic pulmonary embolism after varicocele embolization: a case report.
Article in BMC pulmonary medicine, 2026. 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
backgroundPulmonary glue/iodized oil embolism is an uncommon form of non-thrombotic pulmonary embolism caused by migration of cyanoacrylate-based embolic agents. Although most cases have been reported after endoscopic treatment of gastric varices, cases after varicocele embolization are exceptionally rare, and longitudinal data on clinically stable patients remain limited. CASE PRESENTATION: We report a 35-year-old man who developed acute dyspnea, chest pain, and palpitations immediately after varicocele embolization, mimicking thrombotic pulmonary embolism. Computed tomography pulmonary angiography demonstrated bilateral radiopaque intravascular material within the pulmonary arterial circulation, consistent with migrated glue/iodized oil material, with associated right-dominant consolidation, ground-glass opacities, and minimal pleural effusion. The patient remained hemodynamically stable, with no sustained hypoxemia, right ventricular dysfunction, or pulmonary hypertension, and was managed with individualized conservative/supportive treatment without surgical or endovascular intervention. Follow-up CT at 1 month showed marked regression of parenchymal abnormalities and an apparent partial decrease in the visible radiopaque embolic material. At 6 months, pulmonary function, including DLCO, normalized, echocardiography showed no pulmonary hypertension, and CT findings remained stable. At 1 year, the patient was asymptomatic, and chest radiography showed no clinically significant residual or new parenchymal or pleural abnormality.
conclusionsThis case adds to the limited literature on pulmonary glue/iodized oil embolism after varicocele embolization by documenting a hemodynamically stable course with favorable longitudinal clinical, radiological, and functional follow-up. In carefully selected patients without right ventricular dysfunction or clinical deterioration, conservative/supportive management may be reasonable, but treatment decisions should remain individualized and multidisciplinary.
