POST-TRANSPLANT RENAL ARTERY KINKING ASSOCIATED WITH THE PATIENT'S POSITION: CASE-REPORT
Keywords:Kidney Transplantation, Renal Artery, Renal Artery Obstruction, Vascular surgery
Introduction: Transplant renal artery kinking is an unusual post-kidney transplant complication usually associated with early graft dysfunction.
Methods: We present an unusual clinical manifestation of post-transplant renal artery kinking. A review of the clinical process was made with patient consent.
Results: A 52-year-old male with end-stage renal disease secondary to IgA nephropathy was submitted to cadaveric donor kidney transplant. The patient had good renal function postoperatively, however, after three months the patient began a gradual reduction of diuresis and worsening of renal function, needing to remain in a “squatting position” 5 hours a day to maintain a normal urine output. A bypass between the left external iliac artery and the graft renal artery with an ipsilateral autologous great saphenous vein was made to correct a renal artery kinking and the patient fully recovered.
Conclusion: Renal artery kinking commonly manifested as renal graft dysfunction may have a singular form of presentation. Early intervention is essential to preserve graft viability.
