Tunneled Pleural Catheters in the Management of Chylothorax from Central Venous Catheter-Related Superior Vena Cava Obstruction
Bibliographic record
Abstract
Chylothorax is characterized by the accumulation of chyle in the pleural space, of which the most common cause is trauma or neoplasm. Although chylothorax accounts for a small proportion of clinical pleural effusions, prompt recognition is needed to avoid malnutrition, immunodeficiency, and fibrothorax. We report 2 patients with superior vena cava obstruction caused by tunneled venous catheters resulting in chylothorax and demonstrate the potential safety of tunneled pleural catheters for prolonged chylothorax drainage in an outpatient setting with rigorous follow-up. Changes in pleural fluid chemistries of the effusions and the possible pathophysiology were assessed with a review of the literature on pleural fluid chemistries in superior vena cava obstruction.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
