Falling Through the Cracks: The Need to Include Acute Pancreatitis in Risk Assessment Models for Acute Deep Venous Thrombosis.

Acute pancreatitis is an inflammatory condition caused by an insult to the pancreas. Pancreatitis is associated with local and systemic complications such as splenic vein thrombosis and systemic inflammatory response syndromes (SIRS), respectively. Pancreatitis increases the risk of deep vein thrombosis (DVT) through a combination of increased production of pro-inflammatory cytokines and systemic vascular injury. However, DVT and pulmonary embolism remain under-recognized and underappreciated complications of acute pancreatitis as they fall through the cracks in the commonly used venous thromboembolism (VTE) risk assessment model. We therefore propose that VTE prophylaxis needs to be considered by all clinicians when admitting and evaluating patients with acute pancreatitis and that acute pancreatitis needs to be included on the various VTE risk assessment calculators as it is a significant risk factor for the development of VTE.
