Stroke after Total Hip Arthroplasty / The Japanese Journal of Rehabilitation Medicine

ABSTRACT

During the perioperative period after total hip arthroplasty (THA), much attention has been recently paid to deep venous thrombosis, yet there are few reports concerning stroke after THA and there is no such data at all in Japan at present. The purpose of this retrospective study was to elucidate the occurrence rate and the characteristics of stroke cases during the THA perioperative period. A total of 1,551 primary THAs performed between January 1999 and December 2008 were investigated. Cerebral infarction occurred in three patients (0.19%) during three weeks after THA. Concerning the related factors, one male had foramen ovale, one female had untreated diabetes and atrial fibrillation, and one female had severe stenosis of the internal carotid artery. Cerebral infarction occurred at Day 1 in one male, at Day 2 in one female, and at Day 5 in the other female, and they underwent anticoagulant therapy just after their diagnosis. In all three patients, motor paralysis fully improved and they came back to the THA rehabilitation program within Day 9. One male was discharged at 4 weeks, and another two females were discharged at 8 weeks. Because many people eating a more European diet are now getting older in Japan, prophylaxis for not only DVT but also stroke after THA should be emphasized.
