We report the case of a 33 years old woman who suffered from pain in the left upper arm and a lack of sensibility in the inner part of the left hand 14 days after having had a breast augmentation. We found an increase in d-dimers. Otherwise blood results were normal. Duplex sonography showed a thrombophlebitis of the left vena basilic vein. The patient was treated with Rivaroxaban (Xarelto®) 2 × 15 mg per day for four weeks and had to wear a compression bandage. Due to the treatment, pain relief set in soon. The basilica vein was recanalized five weeks after diagnosis.
