Paget–Schroetter syndrome after a dental procedure in a patient with factor V Leiden (R506Q) heterozygosity
Paget-Schroetter syndrome or effort thrombosis is characterized by spontaneous thrombosis of the upper extremity venous system, commonly seen in a young healthy patient after repetitive use of the upper extremities. It is rarely associated with coagulopathy and thus, hypercoagulable work-up is not usually a part of the investigation. We present a first case of a young woman, who was diagnosed with left upper extremity effort thrombosis following a dental procedure. Interestingly, she was also noted to be heterozygous for factor V Leiden mutation.
