Abdominal pain is often most severe in areas of the bowel with stenoses. This may result in deformations and stenoses. Revascularization of symptomatic stenoses has a much higher therapeutic index compared to asymptomatic lesions. A contrast-enhanced MRV (ATECO) scan has a high detection rate for abnormal transverse sinus stenoses. Stenoses with an iFR between 0.86-0.93 can undergo an FFR assessment to guide therapy. Any stenoses found may be treated by the use of balloon angioplasty, stenting, or atherectomy. Using this typical range, almost 60% of stenoses can be spared from needing vasodilator infusion. These stenoses can be more adequately identified and assessed with catheter cerebral venography and manometry. Multiple stenoses are typically present (mean 8&colon; range 1-25).
