Aneurysm rupture in median arcuate ligament syndrome leading to duodenal stenosis: A case report

Figure 1 Image of contrast-enhanced computed tomography. A: Contrast-enhanced computed tomography (CE-CT) showing a retroperitoneal hematoma, indicating arterial bleeding; B: CE-CT showing celiac artery stenosis (arrow), supporting the diagnosis of median arcuate ligament syndrome; C: CE-CT showing two aneurysms in the inferior pancreaticoduodenal artery (arrow), requiring intervention.

Figure 2 Images of angiogram during interventional radiology. A: Angiography showing aneurysms in the inferior pancreaticoduodenal artery, confirming the bleeding source (arrow); B: Post-embolization angiography showing successful hemostasis with microcoils.

A: Computed tomography (CT) showing gastric distension without duodenal dilation after transcatheter arterial embolization; B: CT showing reduced retroperitoneal hematoma; C: Endoscopy showing edematous duodenal mucosa without ulceration; D: Endoscopic contrast showing stenosis in the third part of the duodenum (arrow).
