No statistically significant differences in procedure-related complications, survival, primary patency, reintervention, or limb-related outcomes were observed during follow-up. These findings should be interpreted cautiously because of the small sample size, treatment-selection bias, and differences in follow-up duration.<\/jats:p>\n
