Acetylsalicylic acid in combination with dihydroergotamine for preventing thromboembolism

In a prospective randomized clinical trial involving 150 patients who underwent major abdominal surgery, acetylsalicylic acid (ASA) and dihydroergotamine (DHE) were examined either alone or in combination for their potential to prevent thromboembolism. Combined treatment with ASA and DHE was found to be more effective in preventing the spread of thrombi and their propagation to the femoral veins.
