Summary. Because of the belief that post-operative deep vein thrombosis (DVT) is rare in Asian patients, thromboprophylaxis is not usually prescribed for surgical patients. This study reports an open multi-centre controlled study of the use of a low molecular weight heparin, nadroparin calcium (Fraxoparine Sanofi France), as opposed to no prophylaxis in 100 patients undergoing uncemented total hip replacement. The patients had bilateral venography performed preoperatively and 10 days after operation. Eight patients (16%) developed DVT in the control group of 50 patients and 1 (2%) in the treatment group, also of 50 patients. Pulmonary embolus occurred in 1 patient in the treatment group and in 3 in the control group. Intraoperative and postoperative blood loss did not differ significantly between the two groups. Our study suggests that the incidence of DVT in Asian patients, though somewhat less than in their Western counterparts, is still considerable. It confirms the safety and efficacy of nadroparin calcium in preventing post-operative DVT in patients undergoing elective total hip replacement.

Résumé. A cause de l’idée selon laquelle la thrombose veineuse profonde post-opéraloire est rare parmi les patients asiatiques, la tromboprophylaxie pour les patients opérés est inhabituelle. Nous avons accompli une étude, comparant la prophylaxie au moyen d’héparine de bas poids moléculaire en utilisant du calcium nadroparine (Fraxiparine Sanofi France) et la non-prophylaxie sur 100 patients subissant un remplacement total de la hanche. Les patients ont subi une vénographie bilatérale avant l’opération et 10 jours après. Huit patients (16%) ont développé une thrombose veineuse dans le groupe de contrôle, contre 1 (2%) dans le groupe traité (p = 0.015, 95% CI 0.02 – 0.67). Trois embolies pulmonaires sont survenues dans le groupe de contrôle et 1 dans le groupe traité (p = 0.27 95% CI 0.04 – 2.44) aucune n’étant fatale. La perte de sang intra-opératoire et post-opératoire n’a pas varié de manière significative entre les deux groupes. Notre étude démontre que l’incidence de la thrombose veineuse profonde post-opératoire chez les patients asiatiques est notable bien qu’elle soit moindre que dans les pays occidentaux et confirme la sûreté et l’efficacité du calcium nadroparine pour la prévenir aprés un remplacement total de la hanche.
