Sinistral portal hypertension, also known as left-sided portal hypertension, is a rare cause of gastric variceal bleeding which occurs secondary to occlusion of the splenic vein. We present a case of venous occlusion and sinistral portal hypertension secondary to distal pancreatic cancer requiring treatment of gastric variceal bleeding. After failing conservative management, transvenous intervention was attempted, but a venous communication with the gastric varices was unable to be identified on multiple venograms. A percutaneous trans-splenic approach using a 21-G needle and ultrasound guidance was successful in directly accessing an intraparenchymal vein feeding the gastric varices, and glue embolization was performed directly through the access needle with excellent results.
