Diagnosis and Management of Acute Limb Ischemia

Introduction: Acute limb ischemia is considered as a life threatening disease .After twelve hours of ischemia, chances of saving the ischemic limb are lower (78%), with higher mortality (31%) as well. Methods: A total of 54 patients who underwent surgery for acute non traumatic limb ischemia between January 2013 and December 2020 were retrospectively reviewed. Results: We included 30 women and 24 men; median age was 69 years. Twenty patients (37%) were presented with upper limb ischemia, where as 34 patients (63%) with lower limb ischemia. Mean delay between the onset of symptoms and hospital admission of upper limb ischemia was 22 hours, 35% of Patients were diagnosed at the stage IIA of Rutherford classification, while 65% were diagnosed at the stage of II B. Lower limb ischemia patients were admitted after 28.5 hours, 64.8% of patients were diagnosed at the stage of II A of Rutherford, while 32.3% were diagnosed at the stage of II B of Rutherford. Revascularization of all ischemic upper limbs (100%) and the majority of ischemic lower limbs (94.1%) were carried out through endovascular thromboembolectomy with Fogarty ballooncathete. Meanlength of hospitalstaywas 8.3 days for upper limb ischemia cases ; while lower limb ischemia patients required 9.2 days of mean hospitalstay. We report a total of 4 deaths (7.4%). Conclusion: Acute limb ischemia remains a challenging entity for clinicians with significant risk of patient limbloss and mortality. Prompt diagnosis, anticoagulation, and timely revascularization are crucial to minimize the risk of limbloss.
