- Abstract
Objectives: To evaluate outcomes of management without surgical revascularization in patients with acute lower limb ischemia (ALI) in a population-based setting. Design: Retrospective observational population-based study. Materials: Patients from Malmö, Sweden, hospitalized for ALI between 2015 and 2018. Methods: In-hospital, surgical, radiological, and autopsy registries were scrutinized for descriptive data on ALI patients managed by endovascular and open vascular surgery, conservative vascular therapy, primary major amputation, and palliative care. Results: Among 161 patients, 73 (45.3%) did not undergo any operative revascularization. Conservative vascular therapy, primary amputation, and palliative care were conducted in 25 (15.5%), 26 (16.1%), and 22 (13.7%) patients, respectively. Conservatively treated patients had Rutherford class ≥ IIb ischemia and embolic occlusion in 33% and 68% of cases, respectively. Their median C-reactive protein level at admission was 7 mg/L (interquartile range 2 – 31 mg/L). Among conservatively treated patients, anticoagulation therapy in half to full dose was given to 22 (88%) patients for six weeks or longer, and analgesics in low or moderate doses were given to twelve (48%) patients at discharge. The major amputation rate at 1 year was 8% among conservatively treated patients, and four patients with foot embolization had not undergone amputation at 1 year. Conclusion: Patients selected for initial conservative therapy of ALI with anticoagulation alone may have a good outcome, even when admitted with Rutherford class IIb ischemia. A low C-reactive protein level at admission seems to be a favorable marker when choosing conservative therapy. A prospective, preferably multicenter, study with a predefined protocol in these conservatively treated patients is warranted to better define the dose and length of anticoagulation therapy.
