Abstract
Background
Chronic limb-threatening ischemia (CLTI) leads to decreased quality of life and increased disease burden, resulting in progressive patient deterioration, limb amputation, and mortality.
Objectives
This study aims to present the outcomes of a Latin American experience using the open distal venous arterialization (DVA) technique for no-option limb salvage in a high volume CLTI center.
Methods
A retrospective case series study was performed including patients from 2018 to 2022 using a population from Bogotá, Colombia. Patients with no-option chronic limb-threatening ischemia underwent open DVA with a 12 month follow-up period. Variables such as operative time, hospital and ICU length of stay, graft material, re-interventions, 1-year patency, amputations and 1-year mortality were recorded.
Results
5 patients with a mean age of 71 years were intervened. 60% were male and 80% had a diabetes mellitus diagnosis. Four patients underwent a reverse great saphenous vein graft procedure and 1 composite polytetrafluoroethylene graft. A total of 80% of patients demonstrated graft patency after 1 year. No perioperative mortalities were recorded but one late postoperative mortality due to myocardial infarction occurred. One major amputation was required, minor amputations were performed in 2 of the patients.
Conclusion
Open DVA is a feasible low cost technique for adequately selected patients with favorable saphenous vein, as evidenced by the limb salvage and graft patency outcomes.
