Short-term Perioperative Thromboprophylaxis After Major Abdominal Surgery

Major abdominal surgery for cancer is major risk factor for thromboembolism. Patients who undergo major abdominal surgery are prone to develop venous thromboembolism, both in the early postoperative period and after hospital discharger. There are strong recommendations in the international guidelines in favor to pharmacological thromboprophylaxis. Thus there is no consensus dor the duration of the prophylaxis. There are authors that suggest extended prophylaxis up to 4 week after surgery. On the other hand, there are prospective randomized trials that inpatient (short-term up to 7-10 days) prophylaxis is adequate.
