We report a 36-year-old woman who presented with a proximal staple-line leak, managed with laparoscopic washout and endoscopic stenting. During apparent clinical improvement, she experienced sentinel haemorrhage on postoperative Day 30, initially attributed to stent-related mucosal trauma. Catastrophic haemorrhage ensued 2.5\u00a0hours later. Endoscopy revealed a clot-filled stent without a mucosal source; computed tomography angiography (CTA) identified a 20\u2009\u00d7\u200918\u2009\u00d7\u200913\u00a0mm splenic artery pseudoaneurysm within the perigastric collection. Proximal coil angioembolization achieved complete exclusion without splenic infarction. The patient made a full recovery and was discharged home on postoperative Day 42. This case illustrates a potentially fatal vascular complication arising during active leak management. A splenic artery pseudoaneurysm must be actively sought in any upper gastrointestinal bleeding during post-LSG leak management, and CTA must exclude a vascular source before attributing bleeding to stent-related mucosal trauma.<\/jats:p>","DOI":"10.1093\/jscr\/rjag782","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T11:36:49Z","timestamp":1787053009000},"source":"Crossref","is-referenced-by-count":0,"title":["Splenic
