Midterm outcome predictors for lower extremity atherectomy procedures

Abstract

Lower extremity atherectomy procedures with the SilverHawk device are safe and effective means in improving symptoms. However, there is decreased durability and significant patency and limb loss over time. Diabetes, renal disease, tobacco use, and tissue loss are all associated with inferior outcomes.

Short‐term outcomes of excisional atherectomy in lower limb arterial disease

“…This study showed 12‐month primary and secondary patency of 66 and 70%, respectively, and reported a 10‐fold increase in restenosis rates if the vessels were undergoing re‐intervention. Sarac et al . recorded primary and secondary patencies of 43 and 57% at 12 months; however, 58% of the cohort in this study had tissue loss, implying a more severely diseased cohort than those in our study.…”

Patterns of procedure-specific radiation exposure in the endovascular era: Impetus for further innovation

“…These new techniques are not readily available, however, and have their own limitations and uncertainties. 17,18 Another limitation is that coronary interventions and procedures done in other facilities were not included in this report. The cumulative level of radiation exposure would be higher if these were included.…”

The role of atherectomy in the treatment of lower extremity peripheral artery disease

“…Sarac et al recruited 167 patients treated with Silver Hawk device in tibial arteries. Cumulative 1-year primary and secondary patency rates were 43% and 57%, respectively [45]. An interesting result comes from Shammas et al trial which demonstrates the inferiority of Silver Hawk atherectomy versus balloon angioplasty.…”
