The outcomes of arterial bypass surgery for chronic lower limb ischemia at Viet Tiep Friendship Hospital during the period from 2022 to 2025

Abstract

Objective: To evaluate the surgical outcomes in the treatment of Chronic lower limb ischemia (CLI) at Viet Tiep Friendship hospital during the period of 2022 to 2025.

Patients and Methods: This was a retrospective descriptive study of patients with chronic lower limb ischemia who underwent surgery at the Cardiothoracic and General Surgery Departments of Viet Tiep Friendship Hospital, from January 2022 to May 2025.

Results: There were 35 patients included in the study. The mean age was 65.17 ± 7.76 years. Among them, 18 patients (51.4%) had a history of hypertension, and 17 patients (48.6%) had a history of smoking. All patients were admitted at a late stage, with 19 patients (54.3%) in stage III and 13 patients (37.1%) in stage IV. TASC D lesions accounted for the majority of cases, with 29 patients (82.9%). Femoral–above-knee bypass surgery was the most commonly performed procedure in the study, applied in 24 patients (68.6%). There were no deaths recorded during the follow-up period. Overally, postoperative ischemic symptoms showed significant improvement.

Conclusion: The majority of patients with chronic lower limb ischemia were elderly and had a history of hypertension and smoking. Patients were often admitted at a late stage with severe and complex vascular lesions. Surgical interventions yielded favorable outcomes.
