Contralateral deep venous thrombosis after hip arthroscopy.

Since the 1980s, hip arthroscopy has become an accepted treatment modality for a variety of hip conditions. It is generally considered a low-risk procedure with a low rate of complications. The risk of developing a deep venous thrombosis (DVT) or venous thromboembolism following these procedures is also thought to be low, and most patients undergoing these procedures receive no pharmacologic prophylaxis postoperatively. This article presents a case of a 33-year-old woman with a history of oral contraceptive use who presented 13 days after a routine hip arthroscopy with pain and swelling in the contralateral thigh. Ultrasonography revealed acute DVTs in the left common femoral, superficial femoral, and popliteal veins. She was admitted to the hospital and treated accordingly. A workup for thrombophilic disorders was negative. We believe that her history of oral contraceptive use, the use of axial traction, and asymmetric forces about the pelvis during the procedure contributed to this postoperative complication. Although this complication is rare and the use of pharmacologic prophylaxis is not common, physicians must be aware of this potential complication following hip arthroscopy.
