Rationale: Owing to the anatomical characteristics of the duodenum, gastroduodenal artery (GDA) pseudoaneurysms can be caused by duodenal ulcers, which may rupture and lead to massive or repeated bleeding. Pseudoaneurysms are usually diagnosed using enhanced computerized tomography or angiography, whereas endoscopic signs have rarely been reported. Patient concerns: Three patients aged 18 to 83 years with bleeding duodenal ulcers and GDA pseudoaneurysms were treated. Diagnosis: All patients had symptoms of gastrointestinal bleeding, and endoscopy revealed duodenal ulcers with visible vessels or adherent clot pulsations. Angiography confirmed the presence of a GDA pseudoaneurysm, which had an adjacent relationship with the duodenum. Interventions: The GDA pseudoaneurysm was embolized in each patient. Outcomes: Through transcatheter arterial embolization, endoscopic treatment, and traditional treatment, hematemesis or melena was gradually stopped and all patients were discharged. Lessons: The pulsation of visible vessels or adherent clots observed during endoscopy in patients with duodenal ulcer may indicate the formation of a gastroduodenal artery pseudoaneurysm. Therefore, we suggest that such patients receive enhanced computerized tomography or angiography to assess whether they need timely endovascular intervention treatment to avoid bleeding caused by a pseudoaneurysm.
Rationale: Transjugular intrahepatic portosystemic stent-shunt (TIPSS) is a minimally invasive procedure used for the treatment of portal hypertension. Intrahepatic hematoma is the rare complication caused by hepatic arterial injuries from TIPSS procedure.Patient concerns: This case report illustrated a 77-year-old man with hepatitis B virus-induced cirrhosis who underwent TIPSS.Diagnoses: The patient suffered from intrahepatic hematoma and hepatic pseudoaneurysm because of the hepatic artery injury after TIPSS.Interventions: The hepatic artery laceration began at the level of the branch of the left hepatic artery was embolized.Outcomes: The acute intrahepatic hematoma and hepatic pseudoaneurysm of the patient were cured. Conclusion:In this report, we describe a cirrhosis patient with a large intrahepatic hematoma secondary to TIPSS, and a literature review is also presented. The intrahepatic hematoma and hepatic pseudoaneurysm should be paid more attention after TIPSS while early-stage prevention should be carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
