The Simpson atherectomy catheter in the management of complete obstructions

Abstract

The Simpson atherectomy catheter has been used successfully to recanalise eleven complete occlusions of the iliac and femoropopliteal arteries. Atherectomy and angioplasty were used in combination in 8 cases. Following atherectomy, all patients showed clinical improvement. Distal pulses returned in 7; rest pain and/or claudication disappeared in the other 4. Ischaemic ulcers healed in the 2 affected patients. Overall, ankle-arm indices (AAI) improved by an average of 0.43, with the improvement being greatest (0.55) in patients in whom the lumen was recanalised to within 91-100% of the native luminal diameter. Seven patients have remained with stable AAI values and without change in their clinical status at 18 months follow-up.

Percutaneous Peripheral Atherectomy of Femoropopliteal Stenoses Using a New-Generation Device:Six-Month Results From a Single-Center Experience

“…36,44 However, individual single-center studies provided overwhelmingly positive long-term results. [27][28][29][30][31][32][33][34][35][37][38][39][40][41][42][43][45][46][47][48][49][50][51][52][53][54][55][56][57][58] In our small cohort, midterm results are encouraging, considering that technically challenging lesions were included in the study. The lowest 6-month restenosis rate we saw was in primary lesions (27%).…”

Initial Clinical Experience with Percutaneous Atherectomy in the Infragenicular Arteries

“…However, the application of atherectomy devices has been limited to vessels with diameters of at least 4 mm. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Even a new, recently tested 7-F atherectomy device proved incompatible with vessels Ͻ4 mm. 24 Added to this size limitation of directional atherectomy are the technical deficiencies seen when the Simpson Atherocath was used in pelvic and femoropopliteal arteries.…”
