Complicaciones vasculares de la pancreatitis

Vascular complications of pancreatitis are infrequent but important clinical problems because of their higher mortality. Pseudocysts that appear in 5%-50% patients with pancreatitis can erode adjacent vessels with hemorrhage, venous thrombosis and pseudoaneurysms. Increase in pressure within pseudoaneurysm can give rise to its rupture, that is the most serious complication of pancreatitis. Intracystic and intraperitoneal or retroperitoneal hemorrhage are the other arterial complications that can occur in the natural history of pancreatitis. Most frequent venous complications are splenic thrombosis, splenoportal thrombosis, and mesenteric thrombosis.
