A case of severe bleeding and deep inferior epigastric pseudoaneurysm after peritoneal dialysis catheter removal
Bibliographic record
Abstract
We present an unusual but severe complication of peritoneal dialysis (PD) catheter removal resulting in significant haemorrhage and hospitalisation. A patient presented for PD catheter removal under local anaesthesia in the interventional radiology suite and was noted to have a heavily calcified deep Dacron cuff. This cuff was intimately associated with a deep inferior epigastric perforating (DIEP) vessel. Removal of the catheter resulted in shearing of DIEP vessel and pseudoaneurysm formation. Despite attempted surgical management with ligation haemorrhage continued, requiring urgent angiographic embolisation to stop the bleeding. Intimate relationship between DIEP vessel and Dacron cuff due to calcification was the cause of this complication. This case report represents a rare but important complication associated with PD catheter removal, highlighting that when calcification is seen at the deep cuff, caution should be exercised and there should be access to angiography suite in case of complication.

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.
