Abstract

Objective: To evaluate the early outcomes of surgical intervention to treat acute lower limb ischemia Rutherford class II. Subjects and Methods: This was a non-controlled, retrospective descriptive study of acute lower limb ischemia patients with Rutherford class II who underwent surgical revascularization from January 2020 to August 2025. Results: Of the 45 patients, the mean age was 69.2 ± 13.9 years; male/female = 3.1/1. The rates of grade IIa and IIb according to Rutherford were 44.4% and 55.6%, respectively. There was no difference in age, gender, comorbidities, and the time from onset to revascularization between the two patient groups. However, group IIb had significantly more calf swelling (64% vs. 5%, p<0.001) and cyanosis (64% vs. 30%, p=0.033) than group IIa. The popliteal artery was the most common site of occlusion. Most patients in group IIa required simple thrombectomy, while 64% in group IIb underwent combined elective fasciotomy. Group IIb was more likely to have postoperative complications, with 12% having recurrent embolization and one case of death. Conclusion: Acute lower limb ischemia with Rutherford class II remained a challenge in diagnosis and treatment. Surgical revascularization under local anesthesia was effective and safe
