Abstract
Objective: To describe the evolution and outcome of a case of gastroduodenal artery pseudoaneurysm in a patient with extrapulmonary tuberculosis. Case details: Female patient, 15 years old, with no previous complications, was admitted to the emergency room with hematemesis without endoscopic control and for that reason was referred to the operating room for emergency laparotomy. During the surgery, tumor in the mesentery (later diagnosed with tuberculosis) and duodenotomy and raffia of the blood vessel were evidenced. Lesion in the second part of the duodenum. Evolved with new episodes of upper gastrointestinal bleeding in the postoperative period being diagnosed with pseudoaneurysm of gastroduodenal artery, performing artery embolization with evolution and discharge with complete recovery of the condition. Final considerations: Pseudoaneurysms usually have a secondary origin: traumatic, inflammatory or infectious. Gastroduodenal artery pseudoaneurysms are rare, corresponding to only 1.5% of all visceral aneurysms. Most of the time, it causes non-specific symptoms such as abdominal pain, in the presence or absence of rupture, and digestive hemorrhage, retroperitoneal or intraperitoneal. Although the low number of known cases limits the experience in the therapeutic approach, it is usually preferable to use endovascular methods to approach them.
