CLINICAL CASE 4 (ALF)

81 year old woman with PAOD (Fontain stage IV) of right lower extremity. Past medical history significant for prior above-knee amputation of left lower extremity.

CTA 20-DEC (MIP, MIP2, mpCPR, CPR)
Maximum intensity projected (MIP) and thin, stretched curved planar reformation (CPR) through the right popliteal artery demonstrate a high-grade (99%) stenosis with collaterals in the supragenual popliteal segment.

DSA / PTA 21-DEC (DSA, DSA2)
Selective DSA, performed on the following day (with guide-wire in place), shows a 5cm occlusion (caused by the guide-wire passing through the high-grade stenosis), which is treated by balloon angioplasty (4mm/8cm).
