Right and left renal arterial tortuosity in the severity groups of MFS patients. Group A - patients without aortic involvement. Group B - patients who had undergone elective surgery of the ascending aorta. Group C - patients who had been operated for either annuloaortic ectasia or type A aortic dissection. Both DM (a) and ICM/SOAM (b) of the two renal arteries were increased in patients who underwent surgery (Group B and Group C) compared to the non-operated group (Group A)
