Aim. Plantar veins’ thrombosis (PVT) is considered as a rare cause of acute foot pain but it also might represent a missed diagnosis because of the higher frequency of the other causes of plantar foot pain.
Methods. We observed seven patients with history of feet stress and subsequent, acute onset, plantar foot pain associated with colour duplex ultrasound (CDUS) findings of PVT.
Results. In all the cases CDUS showed enlarged, uncompressible medial and/or lateral plantar veins without colour-coded signals. Trauma hypotheses included stretching of the feet, direct and repeated compressions, stasis and hyper-extension as the most probable causes of origin of this rare localization of deep venous thrombosis. However PVT may be secondary to other disease.
Conclusion. CDUS investigation can easily provide a direct diagnosis of PVT as well as a sure differential diagnosis with some other causes (e.g. tenopathy, fasciitis) of acute foot pain. CDUS investigation may be indicated to achieve a correct diagnosis in cases of acute foot pain of uncertain origin.
