Bariatric surgery carries a mortality rate of 0.5-1%, with PE found to be the most frequent postoperative complications and causes of death. Currently employed prophylactic methods include unfractionated or low molecular weight heparins in combination with mechanical calf compression. However, despite the implementation of these standard measures, the reported incidence of fatal PE has ranged from 0.2 to 0.64% accounting for between 30 to 50% of deaths after bariatric surgery.
