Abstract:[Objective] To investigate the clinical outcomes of tibia transverse transport (TTT) for diabetic foot ulcer (DFU) complicat- ed with chronic kidney disease (CKD) . [Methods] A retrospective study was conducted on the patients who underwent TTT for DFU in our department from February 2015 to August 2019. Among them, 67 patients with chronic kidney disease were fall into the CKD group, while the other 53 patients without kidney disease were termed as the non-CKD group. The clinical and auxiliary examination results were com- pared between the two groups. [Results] The CKD group consumed significantly longer operation time, hospital stay and external fixator wearing time than non-CKD group (P<0.05) . All the patients were followed up for 4~24 months, with an average of (14.38±4.38) months. During the follow-up period, 7 patients in CKD group died of cardiovascular and cerebrovascular diseases, while no patients in the nonCKD group died (P<0.05) . Although there was no significant difference in the healing rate of foot ulcers between the two groups at the last follow-up (P>0.05) , the CKD group got ulcer healing significantly later than the non-CKD group (P<0.05) . At the last follow-up, the CKD group had higher recurrence rate of foot ulcers and amputation than the non-CKD group, despite of the fact that no significant differences were noted between the two groups (P>0.05) . Angiographically, the findings significantly improved in both groups after surgery(P<0.05) , which in the non-CKD group proved significantly superior to the CKD group at 1 month postoperatively, and bacame not statistically signifi- cant between the two groups at 3 months after surgery(P>0.05) . In terms of lab tests, CRP, Cr and HbA1c significantly decreased in both groups 1 month after operation compared with that before operation (P<0.05) , whereas the Hb, Alb and Urea remained unchanged in both groups (P>0.05) . At the corresponding time point, the CKD group had significantly lower Hb and Alb (P<0.05) , while significantly higher Urea, Cr and CRP than the non-CKD group (P<0.05) . [Conclusion] TTT for treatment of diabetic foot ulcer complicated with chronic kid- ney disease does achieve a higher chance of ulcer healing, with low amputation and recurrence rates.
