Summary

This study looks at a new, less invasive way to treat aneurysms in the arteries that supply the stomach, liver, and spleen. Instead of traditional surgery or X-ray-guided procedures, doctors will use an endoscope with ultrasound to guide tiny coils and glue directly into the aneurysm. The goal is to see if this approach is safe and works well for 30 adults aged 18-60.

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Mar 2026

An estimate. Start dates often move.

Expected to finish

Jul 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patients aged 18-60 years diagnosed with VAA by CT, MRI, or EUS. 2. VAA presenting with any symptoms such as abdominal pain or compression; any asymptomatic VAA located in gastric, gastroepiploic, pancreaticoduodenal, gastroduodenal, mesenteric, or colonic arteries; asymptomatic splenic, renal, hepatic, celiac, jejunal, or ileal artery aneurysms with a diameter \>2 cm; any asymptomatic VAA with an annual maximum diameter increase \>0.5 cm/year; or female patients of childbearing age with VAA. 3. Patients who are allergic to iodinated contrast or are pregnant, and thus are unsuitable for endovascular intervention. 4. VAA that is accessible and identifiable by EUS Exclusion Criteria: 1. Patients with unstable vital signs or those accompanied by major organ dysfunction, severe coagulation disorders (INR \>1.5), active infection, or cardiopulmonary insufficiency, rendering them unable to tolerate endoscopic examination. 2. Patients with uncorrectable coagulation disorders (PT-INR \<1.5 and/or fibrinogen \<120 mg/dL) or uncorrectable thrombocytopenia (platelet count \<20 × 10⁹/L). 3. Patients with a known allergy to intravenous anesthetic agents. 4. Patients who have previously undergone surgical, interventional, or EUS-guided treatment for VAA. 5. Patients unable to provide informed consent.
