One case of percutaneous lung biopsy assisted by artificial pneumothorax technique and literature review.
Review in Medicine, 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
rationaleEarly lung cancer diagnosis is crucial for prognosis, but elderly patients with comorbidities poorly tolerate invasive procedures. Conventional percutaneous biopsy for major vessel-adjacent high-risk nodules has a mere 60% to 70% success rate and high complications, while artificial pneumothorax boosts it to 85% to 90%. This case verifies the technique's safety in this population. PATIENT CONCERNS: A 72-year-old female had a 7-mm left lung ground-glass nodule (2021, no intervention). Follow-up computed tomography (CT) (November 2024) showed the nodule enlarged to 10 × 10 mm with a new 18 × 17 mm irregular consolidation. Empirical anti-infection failed; the lesion was adjacent to the aortic arch and heart, so artificial pneumothorax-assisted CT-guided biopsy was adopted. DIAGNOSES: Video-assisted thoracoscopic surgery confirmed stage IA1 (tumor, node, metastasis stage T1aN0M0) lung adenocarcinoma (lepidic-predominant + invasive mucinous subtypes), with negative margins and no vascular, nerve, or pleural invasion.
interventionsCT-guided artificial pneumothorax-assisted percutaneous lung biopsy, followed by video-assisted thoracoscopic surgery left upper lobectomy plus lymph node dissection. OUTCOMES: Vital signs were stable; drainage tube removed on day 4 post-biopsy. One-month follow-up: no hemoptysis, chest pain, or pneumothorax; CT showed no intrapulmonary exudation. LESSONS: The technique is safe for lesions adjacent to the heart and major vessels. However, large-sample studies and artificial intelligence-based nodule analysis are needed to further verify its efficacy.
