title: Tarsal tunnel syndrome associated with a perforating branch from posterior tibial artery: a case report.
abstract: Tarsal tunnel syndrome, a compressive neuropathy of the tibial nerve or its branches with in the tarsal tunnel, is an uncommon condition. Various etiologies of the syndrome have been described. We report a rare case of tarsal tunnel syndrome associated with a perforating branch from the posterior tibial artery. A 56-year-old woman presented with 1-year history of paresthesia and hypoesthesia in the medial and lateral plantar area of the left foot. Tinel's sign was elicited at the tarsal tunnel. Electrodiagnostic studies confirmed the diagnosis of left tarsal tunnel syndrome. Intraoperatively, the perforating branch from posterior tibial artery which traveled through a split in the tibial nerve was encountered. The patient's symptom improved significantly at 2 years after tarsal tunnel release and vascular ligation. Only a minor degree of paresthesia remains in the forefoot.
