Objective:
To evaluate the clinical profile and outcome of arterial pseudoaneurysms (PSA) associated with acute and chronic pancreatitis (CP).
Methods:
Records of all patients of pancreatitis from 2010 to 2016 were analyzed retrospectively for the development PSAs; clinical profile and outcome parameters were compared between PSAs associated with acute and CP.
Results:
Of the 980 patients, 46 (all males, age 39.70 ± 11.78 years) developed PSAs, including 19 of 600 of acute pancreatitis (AP) and 27 of 380 of CP. The most common clinical presentation was bleeding (37, 80.4%). The majority of patients was managed nonsurgically, with endovascular embolization in 31 (67.4%) and percutaneous thrombin injection in 9 (19.6%) patients. Pseudoaneurysms in patients with AP were associated more often with fluid collections (94.7% vs. 55.6%, P = 0.004) with more requirement of surgery compared to patients with CP (15.8% vs. 3.7%, P = 0.033). The pattern of arteries involved with PSAs and outcome was similar in AP and CP patients.
Conclusion:
Arterial PSAs were more commonly associated with CP compared to AP with similar presentations. Associated fluid collections and requirement of surgical intervention were higher in PSAs in patients with AP compared to patients with CP.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
