Recurrences after surgical treatment of patients with post-thrombotic syndrome of the lower extremities.

A Linton flap operation was performed in 148 patients with post-thrombotic syndrome of the lower extremities. One-hundred and five patients were followed up from 6 months to 10 years and 14.5% of cases had recurrent ulcers. The most common causes of recurrence was further deep venous thrombosis or remaining incompetent perforating veins. All patients with a recurrence of their ulcer had a further operation and incompetent perforating veins were ligated and divided with good clinical results.
