What this Trial Is About
This research focuses on acute pancreatitis, a rare but serious inflammation of the pancreas that can occur after percutaneous mechanical thrombectomy (PMT), a minimally invasive procedure used to treat blood clots in arteries and veins. The study aims to determine how often acute pancreatitis happens following PMT, understand the factors that increase risk, evaluate patient outcomes, and develop a clear approach for diagnosis and treatment. PMT, including devices like the AngioJet system, is increasingly used for various vascular conditions such as deep vein thrombosis and arterial blockages. The study examines patients who developed acute pancreatitis within 14 days after undergoing PMT for thrombotic disorders. It reviews patient and procedural data retrospectively to identify incidence rates and severity, focusing on those treated for peripheral vascular diseases. The study does not involve new treatments but observes outcomes and clinical courses following the PMT procedure. Participants' medical records are analyzed to assess the occurrence of acute pancreatitis and acute severe pancreatitis within two weeks post-procedure. The research evaluates clinical outcomes and aims to establish a diagnosis and treatment pathway based on these findings. The study spans a retrospective period starting from 2016 and continues through 2026, with no direct participant visits or interventions, as it is observational in nature.
