Venous thromboembolic complications are an uncommon but significant cause of morbidity & mortality after live donor hepatectomy . The precise incidence of these events and the current practices of centers performing living donor liver transplantation worldwide are unknown.


An online survey was shared amongst living donor liver transplantation centers containing questions regarding center activity, center protocols for donor screening, peri‐operative thromboembolic prophylaxis and an audit of ‐perioperative venous thromboembolic events after live donor hepatectomy in the previous five years (2016–2020).


Fifty‐one centers from twenty countries completed the survey. These centers had cumulatively performed 11500 living donor liver transplants between 2016–2020. All centers included pre‐operative l assessment for thromboembolic risk amongst potential liver donors in their protocols. Testing for inherited prothrombotic conditions was performed by 58% of centers. Dual‐mode prophylaxis was the most common practice (65%), while eight and four centers used single mode or no routine prophylaxis respectively. Twenty (39%) and 15 (29%) centers reported atleast one perioperative deep venous thrmobosis or pulmonary embolism event respectively. There was one donor mortality directly related to post‐operative pulmonary embolism. Overall incidence of deep venous thrombosis and pulmonary embolism events was 3.65 and 1.74 per 1000 live donor hepatectomies respectively. Significant variations in center practices and incidence of thromboembolic events was identified in the survey primarily divided along world regions. 75% of participating centers agreed on the need for clear international guidelines.


Venous thromboembolic events after live donor hepatectomy are an uncommon but important cause of donor morbidity. There is significant variation in practice among centers. Evidence‐based guidelines regarding risk assessment, and peri‐operative prophylaxis are needed.
