The study found that approximately 8.4% of patients with chronic pancreatitis developed vascular complications, mainly splanchnic venous thrombosis. Splenic vein thrombosis was the most common, while arterial pseudoaneurysm was less common. Most patients were asymptomatic with no variceal bleeding, possibly explained by well-developed collateral circulation and strict study inclusion criteria.
Introduction: Chronic pancreatitis (CP) is a long-standing progressive inflammation of the pancreas, which can lead to a variety of vascular complications, such as splanchnic venous thrombosis (VT) and arterial pseudoaneurysm (PA). There is a lack of studies on vascular complications in Scandinavian countries. Methods: We performed a retrospective analysis of medical records of patients with CP identified from the Karolinska University Hospital database between 2003 and 2018. A total of 394 patients with definite CP were included in the study. Results: There were 33 patients with vascular complications, with a median age of 62 (IQR 55-72) years. The cumulative incidence of vascular events was 3.2% at 5 years. Thirty patients had isolated VT, whereas three patients had PA (7.6% and 0.8%, respectively). Isolated splenic vein thrombosis was most common (53.3%), followed by a combination with other splanchnic veins. PA was found in the splenic artery in two patients and in the left gastric artery in one patient. Varices were present in three (10%) patients; variceal bleeding was not recorded. All patients had asymptomatic splanchnic VT, most with chronic VT with developed collaterals (83.3% had abdominal collateral vessels). Nearly two-thirds of patients with VT (63.3%) received no treatment, whereas 11 (36.6%) were treated with anticoagulants. Pseudocysts and alcoholic etiology of CP are risk factors for vascular complications. Conclusions: The cumulative incidence of vascular complications was 3.2% at 5 years. Splanchnic VT is more common than PA. Patients were asymptomatic with no variceal bleeding, explained by well-developed collateral vessels and strong study inclusion criteria.
