Spontaneous arteriovenous fistulation of a pseudoaneurysm into superior mesenteric vein (SMV) has rarely been reported. We present the case of a 61-year-old woman who presented with a post pancreatic arterioportal fistula (APF) that was successfully managed by stent graft (SG) placement in the gastroduodenal artery (GDA). We also review the published experience of the endovascular management of mesenteric extrahepatic APFs. This review demonstrates the evolution from open surgical to endovascular management for majority of these patients.

Background: Metastases in the lateral pelvic lymph nodes or mesenteric lymph nodes represent distinct categories of mid-low rectal cancer. This study investigated the patterns of mesenteric and lateral pelvic lymph node metastases in mid-low rectal cancer; the survival benefit of postoperative treatment was also analysed in these groups.
Methods: This retrospective multicentre study included consecutive patients with mid-low rectal cancer who underwent total mesorectal excision with lateral pelvic lymph node dissection in three Chinese institutions between 2012 and 2020.

Retroperitoneal hemorrhage in patients with vascular Ehlers-Danlos syndrome (vEDS) is uncommon, and its optimal management remains controversial because both surgical and endovascular interventions carry substantial risks. A 36-year-old man with vEDS presented with persistent upper abdominal pain. Computed tomography (CT) revealed a massive retroperitoneal hematoma, approximately 20 cm in size, with a pseudoaneurysm in a mesenteric artery branch but without contrast extravasation.

Chronic mesenteric ischemia (CMI) is a rare, yet increasingly prevalent, condition, especially among older adults. Diagnosing CMI in older adults presents significant challenges. Along with the burden of comorbidities and the physiological changes associated with aging, timely intervention is often delayed, leading to poorer outcomes.

Chronic mesenteric ischemia typically presents with postprandial abdominal pain and weight loss due to atherosclerotic stenosis of mesenteric arteries. Endovascular treatment has become the first-line management, demonstrating lower early mortality and fewer complications compared to open surgery. Recent evidence shows that covered stents provide superior long-term outcomes, with better primary patency and freedom from reintervention than bare-metal stents.

The robotic approach to liver and pancreatic surgery is expanding worldwide. However, limited data are available on vascular management in these complex procedures. The unique characteristics of the robotic platform may enhance the feasibility of minimally invasive vascular resection and reconstruction.
