Introduction
Chronic limb-threatening ischemia (CLTI) is a severe condition with high risks of amputation and mortality. A groundbreaking study by Ding et al. (2024) has revealed the potential of combining Tibial Cortex Transverse Transport (TTT) with Endovascular Therapy (EVT) to enhance outcomes for patients suffering from CLTI.
Key Findings
• At 6 months, 85.5% of patients in the TTT+EVT group achieved Amputation-Free Survival (AFS) compared to 72.4% in the EVT-only group.
• Wound healing rates at 6 months were 54.5% for TTT+EVT versus 51.3% for EVT-only.
• At 12 months, TTT+EVT continued to show superior outcomes, with AFS of 81.9% versus 48.9% in the EVT-only group, and wound healing rates of 72.7% compared to 46.7%.
Methodology
The study retrospectively analyzed 131 patients with CLTI (Rutherford category 5 or higher) at Guangxi Medical University. Patients were divided into two groups:
• Control group: Received EVT alone.
• Experimental group: Received a combination of TTT and EVT.
Conclusion
The addition of TTT, a technique inspired by Ilizarov’s distraction osteogenesis principles, significantly improved both AFS and wound healing rates. These findings, if confirmed, suggest a potentially promising avenue for enhancing limb salvage in patients with advanced CLTI.
