Complications and Antiplatelet and Anticoagulant Therapy in Vascular Surgery.

The goal of this retrospective clinical trial is to find out association antiplatelet and anticoagulant therapy with perioperative complications in non-cardiac vascular surgery in patients . The main questions it aims to answer are: Does the use of antiplatelet agents and anticoagulants affect the development of complications in the perioperative period during operations on the main arteries? Does discontinuing antiplatelet and anticoagulant medications affect the development of perioperative complications in major artery surgeries?? Researchers will compare with patients who didn't use antiplatelets and anticoagulant drugs to see ift he incidence of complications comparable? This is a retrospective study based on the analysis of medical records (case histories).
