Abstract
To evaluate tibial single access in treatment of chronic total occlusions (CTO) in patients with ipsilateral chronic-limb ischemia (CLTI). In this retrospective study, data was collected on patients treated for ipsilateral CTO via a tibial artery access between March 2017 and March 2021. Fifty-nine limbs in 57 patients, (42 men, average age 73years; range 47-96) were treated. Patient's symptoms were classified in accordance with the Rutherford category. The end points were freedom from major amputation and the need for reintervention up to 1year of follow up. Out of the 59 treated limbs, technical success was achieved in 57 (97%). The treated multilevel segments involved 5 common and 12 external iliac arteries, 23 common and 37 superficial femoral arteries, 23 femoropopliteal segments, 14 popliteal arteries, and 4 bypasses. Mean length of occlusion was 186 mm (range 7-670). Rutherford classification of the treated limbs was category 5 and 6 in 45 patients and category 4 in 14 patients. Three procedural complications occurred and were successfully treated during the same procedure. No immediate post-procedural complication was encountered. Median follow-up was 13months (range 1-45.3). Reintervention was required in 9 limbs, after an average of 6months. One year free from amputation rate was 91.2%. Single access via the ipsilateral tibial artery can be a useful, effective, and safe approach for treating CTO in CLTI patients.
