Pulsation of visible vessel or adherent clot in duodenal ulcer may indicate pseudoaneurysm: Case series.

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.
