May-Thurner syndrome in a pediatric renal transplant recipient - Case report and literature review

Vascular complications post-renal transplantation are not very common and can be associated with increased risk of graft loss. We report an unusual case of a young, female teenager with asymmetrical leg swelling. After one month of transplantation, the patient developed a rise in serum creatinine with right leg swelling (ipsilateral to transplant) from compression of the iliac vein by a right renal transplant lymphocele, which resolved after lymphocele drainage. Subsequently, left leg swelling (contralateral to transplant) was noticed and the diagnosis of May-Thurner syndrome was made by MRV. The patient was successfully managed with oral Plavix, stockings and leg elevation. The allograft function remained stable at 18 months post-transplant.
