Intervention for Long SFA Stenosis
- Operators: Dierk Scheinert, MD, Dong Hoon Choi, MD
Clinical Information

- Relevant clinical history and physical examination:
A 56-year-old woman was presented with claudication (50m). She had suffered from long standing diabetes mellitus and ESRD. She underwent kidney transplantation 7years ago. ABI and CT angiogram revealed significant stenosis at both superficial femoral artery. Six months ago, she was underwent stenting at left superficial femoral artery. She was admitted for PTA at right superficial femoral artery. Her dorsal and postero-tibial artery pulse was very weak.

- Relevant test results prior to catheterization:
CT angiography showed segmental moderate to severe stenosis of both superficial femoral artery. (Figure 1)
Segmental limb pressure with doppler revealed moderately decreased both ankle-brachial index and pressure drop of both femoro-popliteal segments.

- Relevant catheterization findings:
Severe stenosis of right superficial femoral artery was found on angiography. (Figure 2)

Interventional Management
- Procedural step:
After Lt. femoral puncture, The Flexor Tuohy-Borst Silde-Arm Introducer (ansel 7Fr) was inserted. We crossed the lesion using terumo wire and percutaneous transluminal angioplasty was performed using a Powerflex 5.0/80mm. SMART stents (6.0*150mm, 6.0*80mm) was successfully deployed (Figure 3). Adjunctive ballooning using Powerflex 40 x 7.0 was performed. Good patency was achieved in right EIA (Figure 4).
