A 43-year-old female patient (para 9 with her last delivery two months prior) known hypertensive for 10 years presented to our department with gastrointestinal bleeding in the form of hematemesis, multiple episodes of melena, and hematochezia for one week. She also complained of weight loss and non-radiating and self-relieving epigastric pain not associated with positional changes. The patient was then assessed for causes of pseudoaneurysm formation, which primarily includes pancreatitis and cholecystitis. However, no significant abdominal tenderness, palpable abdominal mass, jaundice, flank tenderness, and increase in serum lipase and amylase were observed. The only significant findings included laboratory studies showing mild anemia with a hemoglobin of 9.6 g/dL, hematocrit of 29.5%, mean corpuscular hemoglobin (MCH) of 26.7, and red blood cells of 3.6 × 10^12/L, for which she was transfused two units of blood and started on injectable Vitamin K (10 mg, once daily), injectable tranexamic acid (500 mg, TDS), and omeprazole infusion (40 mg, once daily). After two days, her hemoglobin levels of 12.4 g/d, hematocrit of 37.5%, MCH of 26.7, and red blood cells 4.64 × 10^12/L. Meanwhile, mesenteric CT angiography also showed multiple splanchnic pseudoaneurysms involving the celiac axis trifurcation, gastroduodenal artery, superior/inferior pancreaticoduodenal artery, and jejunoileal branch of the superior mesenteric artery, and a large partially thrombosed pseudoaneurysm arising from superior pancreaticoduodenal branch causing a significant mass effect on the second part of duodenum as seen in Figure .\nBased on such findings, coiling and embolization of the corresponding arteries were planed. Accordingly, the right common femoral artery was used as the access route with a retrograde 5-Fr catheter, which provided access to the celiac trunk and then into the gastroduodenal artery using a 4-Fr C2 and microcatheter. The large aneurysm in the gastroduodenal artery was identified and crossed. Multiple other small aneurysms with secondary aterio-venous malformations were also observed. The whole flow circuit (retrograde and anterograde) to the large aneurysm was packed with multiple coils, with the aneurysm sack also being coiled can be seen in Figure .\nThe second aneurysm in the pancreaticoduodenal artery was accessed after multiple attempts, showing multiple coils of variable sizes blocking the aneurysm sack and its retro- and anterograde flow evident from Figure .\nAs seen in Figure repeat angiography revealed good outcomes, with no retrograde or anterograde filling of aneurysm and immediate complications having been observed.\nPostoperative care included augmentin administration (1 mg, intravenous; two doses) with positional changes to prevent any hematoma formation. The patient was advised to keep her head tilted on 45-degree angle. She was observed for one more day for any hematoma formation or bleeding prior to discharge.
A 55-year-old male diagnosed case of ethanol-related chronic pancreatitis presented with frequent episodes of melena associated with paroxysms of abdominal pain. He was given blood transfusions elsewhere for severe anemia. As patient had persistent GI bleeding with repeated drop in hemoglobin, he was referred for further evaluation and management. On clinical examination, he had profuse sweating, hypotension, tachycardia, severe pallor and mild tenderness in the epigastrium. His laboratory investigations revealed hemoglobin of 7.1 g% and hematocrit of 22%, mild renal failure and increased serum triglycerides. Contrast-enhanced computed tomography of the abdomen showed evidence of chronic calcifying pancreatitis (). Esophagogastroduodenoscopy with a standard scope and colonoscopy were normal. Repeat esophagogastroduodenoscopy with a standard scope after an episode of melena showed active bleeding from the ampulla (). Angiographic study could not localize the site of bleeding. Endoscopic ultrasound showed chronic pancreatitis with a heterogeneous inflammatory lesion in the body of the pancreas (). As the bleeding source could not be localized and the patient had ongoing melena and drop in hemoglobin, emergency exploratory laparotomy was performed after initial hemodynamic stabilization. Pancreas was seen adherent to splenic vessels and hilum. There was evidence of splenic vein rupturing into the main pancreatic duct. Distal pancreatectomy with splenectomy was performed. The patient had an uneventful recovery postoperatively. Postoperative histology demonstrated chronic calcifying pancreatitis (), lymphnodes with reactive hyperplasia and congested spleen (). He was discharged in a hemodynamically stable condition and there was no further recurrence of GI bleeding after 6 months of follow up.
