Objective To explore the vascular conditions and the necessity of vascular reconstruction in the treatment of chronic ischemic diseases of lower extremities with tibial transverse transport (TTT) from the perspective of vascular surgery.Methods A clinical data of 59 patients with chronic ischemic disease of lower extremities treated by TTT between February 2014 and July 2019 were analyzed retrospectively. Among them, there were 41 patients with diabetic foot (DF), including Wagner grade 3-4, Texas grade 2-3, and stage B-D lesions; the disease duration ranged from 0.7 to 2.4 years, with an average of 1.5 years, and 5 cases complicated with arteriosclerosis obliteran (ASO). There were 14 patients with ASO (Fontaine stage Ⅳ and Rutherford stage Ⅲ-Ⅳ) with an average disease duration of 10.8 months (range, 1.5-23.4 months). There were 4 patients with thromboangiitis obliteran (TAO) with an average disease duration of 12.3 months (range, 2.1-18.2 months), and the clinical stages were all in the third stage. In 18 patients that ankle brachial index (ABI) of anterior or posterior tibial artery was less than 0.6 before operation, or the blood flow of the three branches of inferior anterior tibial artery did not reach the ankle by imaging examination, vascular reconstruction was performed before TTT (5 cases of DF combined with ASO, 12 of ASO, 1 of TAO). After operation, the effectiveness was evaluated by ulcer wound healing, skin temperature, pain visual analogue scale (VAS) score, ABI, and CT angiography (CTA) examination.Results The patients with DF were followed up 8-16 months (mean, 12.2 months); the ulcer wounds healed with a healing time of 5.1-9.2 weeks (mean, 6.8 weeks); CTA examination showed that the branches of inferior anterior tibial artery were opened in 5 patients after revascularization; and the tibial osteotomy healed for 5-14 weeks (mean, 8.3 weeks). The patients with ASO were followed up 13-25 months (mean, 16.8 months); the ulcer wounds healed with a healing time of 6.2-9.7 weeks (mean, 7.4 weeks). CTA examination showed that the branches of inferior anterior tibial artery were opened in 12 patients after revascularization; all tibial osteotomy healed, and the healing time was 4.5-14.4 weeks (mean, 10.2 weeks). The patients with TAO were followed up 12-23 months with an average of 12.3 months, and toe/limb amputation was performed after ineffective treatment. The patients were divided into two groups according to whether they were combined with revascularization or not. The ABI, VAS score, and skin temperature in the combined revascularization group significantly improved at 6 months after operation (P<0.05); while there was no significant difference in ABI at 6 months after operation in the TTT group (P>0.05), but the skin temperature and VAS scores significantly improved when compared with those before operation (P<0.05).Conclusion The ABI of anterior or posterior tibial artery is more than 0.6, radiological examination shows that at least one of the three branches of inferior anterior tibial artery leads to ankle artery, which is a prerequisite for successful TTT in the treatment of chronic ischemic disease of lower extremities. DF is the indication of TTT. ASO can choose TTT, and TAO should use this technique cautiously.
