Interventional therapy for gastric remnant hemorrhage post-Billroth II subtotal gastrectomy in an 85-year-old man. a, b, No stomach-related blood supply arteries are seen on angiographies of the celiac axis and superior mesenteric arteries, respectively; c, A microcatheter is superselected to the left phrenic artery, after which gelatin sponge particles are used for decompressive embolization; d, Initial re-bleeding persisted despite using an endoscopically-implanted titanium clamp. A repeat angiography reveals a branch of the left hepatic artery (arrow) flow towards the titanium clips (arrow); e, A microcatheter is superselected to the suspected bleeding vessel, followed by empiric embolization using gelatin sponge particles; f, The terminal branch of the left internal thoracic artery is found to run near the titanium clips (arrow), and embolization is performed similarly
