Successful Emergency Cardiac Surgery for Intraoperative Pulmonary Artery Tumor Embolism During Renal Cell Carcinoma Surgery: A Case Report.
Article in IJU case reports, 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
Introduction: Intraoperative tumor thrombus embolization during renal cell carcinoma (RCC) surgery with inferior vena cava (IVC) tumor thrombus is a rare but potentially fatal complication. We report successful emergency cardiac surgery for massive pulmonary artery tumor embolism. Case Presentation: A 75-year-old female with left RCC and IVC tumor thrombus underwent radical nephrectomy. Pre-existing left pulmonary artery tumor embolism was noted preoperatively. During IVC manipulation, the tumor thrombus dislodged and migrated through the right heart to completely occlude the right pulmonary artery, causing cardiac arrest. Through multidisciplinary collaboration, nephrectomy was completed under cardiac massage, followed by emergency cardiopulmonary bypass and pulmonary artery thrombectomy. The patient recovered completely without neurological sequelae. Conclusion: This case demonstrates the critical importance of preoperative risk assessment, intraoperative transesophageal echocardiography monitoring, and immediate multidisciplinary decision-making in managing this life-threatening complication. The "double hit" mechanism of pre-existing and acute pulmonary embolism significantly worsened the clinical course.
