This study aimed to report a single centre management experience and mid term outcomes for symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD). This was a retrospective observational study. Between 1 August 2012, and 30 June 2018, consecutive patients with symptomatic SISMAD were included. Patient demographics, clinical symptoms, comorbidities, risk factors, and dissection characteristics were obtained. The treatment regimens and clinical and follow up outcomes were reviewed and analysed. A chi square test, Fisher's exact test, or one way analysis of variance was used to compare variables between the groups. Binary logistic regression was used to determine predictive factors for failed conservative treatment. The cumulative rate of complete dissection remodelling was calculated using a Kaplan-Meier curve. Sixty-two patients (mean age, 56.0±9.3 years) were included. Patients at risk of intestinal ischaemia or dissecting aneurysm rupture were considered to be high risk patientse treatment. This study found that conservative treatment showed satisfactory symptom resolution for low risk SISMAD patients. Endovascular stenting was associated with a high technical success and dissection remodelling rate. This treatment modality might be reserved for patients with high risk SISMAD or failed conservative treatment. In addition, a dissection length ≥50 mm was a risk factor for failed conservative treatment. The ABO blood group may influence the development and progression of cancer. In particular, the prognosis of patients with blood type O is better for pancreatic adenocarcinoma, although this has not been extensively explored in pancreatic neuroendocrine tumors (PanNET). To assess the influence of the ABO and Rhesus blood types on the risk of recurrence in patients who underwent curative intent PanNE
