A 39-year-old man was admitted to the hospital due to hematemesis and melena for 2 wk, with a new episode lasting 1 d.\nTwo weeks before admission, the patient had hematemesis and melena without obvious known causes. He vomited light red fluids 4-5 times/d and passed tarry stools 3-4 times/d; these events were accompanied by epigastric pain, abdominal distension, and fatigue. He had no dizziness or syncope. He was hospitalized at a local hospital where examinations showed a hemoglobin (Hb) level of 86 g/L. Esophagogastroduodenoscopy (EGD) showed fresh blood in the descending part of the duodenum but did not show a clear bleeding site. The patient was treated with blood transfusion, acid blockers, and intravenous (IV) fluid and discharged from the hospital after no recurrence of hematemesis or melena was observed.\nOne day before admission to our hospital, the patient vomited bright red blood once and was admitted to the local hospital. Bedside EGD showed no obvious bleeding in the upper gastrointestinal tract. During his hospitalization, the patient had repeated hematemesis and hematochezia 4-5 times/d accompanied by left upper abdominal pain and fatigue. His minimum Hb level was 42 g/L. After treatment with blood transfusion, IV fluid, acid blockers, and hemostasis, he was transferred to our hospital for emergency admission.\nThe patient had a history of chronic pancreatitis. He denied chronic diseases such as hypertension, coronary heart disease, and diabetes, a history of abdominal surgery and trauma, and a history of food and drug allergy.\nThe patient denied a history of smoking and drinking and any history of diseases in family members.\nOn admission, the patient had a body temperature of 37.2 °C, a pulse of 102 beats/min, a respiratory rate of 19 times/min, a blood pressure of 117/91 mmHg, and an oxygen saturation of 98%. The patient had manifestations of anemia and pale conjunctiva. His abdomen was soft with upper abdominal tenderness. No rebound tenderness was noted. No abdominal mass was palpable. No other obvious abnormality was noted.\nThe complete blood count on admission was as follows: White blood cell count, 8.00 × 109/L; red blood cell count, 2.34 × 109/L; Hb, 66 g/L; hematocrit, 0.192; platelet count, 108 × 109/L; total amylase, 198 U/L; D-dimer, 6060 µg/L; hypersensitive C-reactive protein, 40.1 mg/L; procalcitonin, 0.12 ng/mL; and serum albumin, 24 g/L (Table ). Coagulation function, alanine aminotransferase, aspartate aminotransferase, total bilirubin, alkaline phosphatase, glutamyl transpeptidase, urinalysis results, stool analysis, tumor marker expression, troponin I, and electrocardiogram results were all within normal limits.\nA noncontrast-enhanced computed tomography (CT) scan of the abdomen and pelvis showed pancreatic swelling, uneven density, vague edges, multiple spots of calcifications, and hyperintense opacities in the pancreatic head and body, indicating chronic pancreatitis and pancreatic head hemorrhage.\nSubsequent contrast-enhanced CT of the abdomen showed isointense, rounded opacities with a diameter of approximately 41 mm in the pancreatic head that were enhanced with contrast in the arterial phase and were closely related to the gastroduodenal artery, indicating pseudoaneurysm (Figure ). Furthermore, digital subtraction angiography performed via the celiac trunk showed the formation of pseudoaneurysms at the proximal gastroduodenal artery; the remaining blood vessels were unremarkable (Figure , Video 1A).
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.
