Abstract
IntroductionInflammation-induced dysregulation of the coagulation cascade and vascular stasis in hospitalized patients with acute necrotizing pancreatitis (ANP) serve as a milieu for venous thromboembolism (VTE). Deep vein thrombosis (DVT) and pulmonary embolism (PE) are often underrecognized. We evaluated the incidence and risk factors for VTE in a cohort of patients with ANP. MethodsAll adult patients with ANP at our center between 2009 and 2022 were followed for three months after index hospitalization and categorized into cases and controls based on development of VTE. Demographic, clinical, and radiologic characteristics during admission were compared. A multivariable analysis was done to identify independent predictors for VTE. A p value of <0.05 was taken as significant. ResultsAmong 643 ANP patients, 512 [males-350, median age-52 years] were eligible for inclusion. VTE developed in 64 (12.5 %) patients – 28 DVT (5 %), 22 PE (4 %) and both in 14 (3 %) after a median 16 days from the diagnosis of ANP. Significant independent predictors for VTE on multivariable analysis were age ≥60 years (OR 1.91; 95 % CI 1.04–3.53), peri-pancreatic extent of necrosis (OR 7.61; 95 % CI 3.94–14.70), infected necrosis (OR 2.26; 95 % CI 1.13–4.50) and total length of stay ≥14 days (OR 4.08; 95 % CI 1.75–9.50). ConclusionsThe overall incidence of VTE in our cohort of patients with ANP was 12.5 %, which was usually diagnosed within one month of hospitalization. High-risk patients can be stratified based on clinical and imaging characteristics and may benefit from intensive DVT screening and prophylaxis during hospitalization and following discharge.
