Background: Treatment guidelines for splanchnic vein thrombosis in necrotizing pancreatitis are lacking due to insufficient data on the full clinical spectrum. Methods: We performed a post-hoc analysis of a nationwide prospective necrotizing pancreatitis cohort. Multivariable analyses were used to identify risk factors and compare the clinical course of patients with and without SVT. Results: SVT was detected in 97 of the 432 included patients (22%) (median onset: 4 days). Risk factors were left, central, or subtotal necrosis (OR 28.52; 95% CI 20.11–40.45), right or diffuse necrosis (OR 5.76; 95% CI 3.89–8.51), and younger age (OR 0.94; 95% CI 0.90–0.97). Patients with SVT had higher rates of bleeding (n = 10,11%) and bowel ischemia (n = 4,4%) compared to patients without SVT (n = 14,4% and n = 2,0.6%; OR 3.24; 95% CI 1.27–8.23 and OR 7.29; 95% CI 1.31–40.4, respectively), and were independently associated with ICU admission (adjusted OR 2.53; 95% CI 1.37–4.68).

Spontaneous recanalization occurred in 62% of patients (n = 40/71). Radiological and clinical outcomes did not differ between patients treated with and without anticoagulants. Discussion: SVT is a common and early complication of necrotizing pancreatitis, associated with parenchymal necrosis and younger age. SVT is associated with increased complications and a worse clinical course, whereas anticoagulant use does not appear to affect outcomes
